8′ Front Door: Factory Sourcing Guide for B2B Buyers (2025)

21 min read

A procurement manager in Ohio once sent me a photo of a warped 8-foot door slab leaning against a warehouse wall. The finish was blistered. The stile had twisted a full half-inch. His supplier had shipped it without a moisture barrier, and the ocean voyage had done the rest. That door cost him $1,400 landed. He spent another $600 trying to make it work before scrapping it.

That story repeats itself more often than most buyers admit. The 8′ front door segment is growing—taller entryways have become a standard request in custom residential and light commercial projects—but the failure rate among imported doors is disproportionately high. The reason is rarely the factory’s machinery. It is almost always a mismatch between what the buyer specified and what the factory actually tested, packed, and shipped.

This guide covers the technical specifications that matter at 8 feet tall, the performance standards you should demand, and a practical framework for evaluating factories before you commit a container’s worth of budget.

1. Understanding the 8′ Front Door Size Standard

An 8′ front door refers to a door slab that is 96 inches (2438 mm) tall, typically paired with widths from 36 to 48 inches. The rough opening must be framed approximately 2 inches larger in both dimensions to accommodate the jambs and leveling shims.

The 96-inch height has become a de facto standard in North American residential construction, particularly in the custom and semi-custom segments. Builders spec it for the visual proportion it gives to high-ceiling foyers. Architects use it to align door heights with window headers. Multi-family developers use it to differentiate their units from standard 80-inch production builds.

1.1 Dimensional Breakdown: Rough Opening vs. Door Slab

Understanding the difference between slab dimensions and rough opening dimensions prevents the most common ordering error in this category.

Dimension	Door Slab (Typical)	Rough Opening (Typical)
Height	96″ (2438 mm)	98″ (2489 mm)
Width (single)	36″ (914 mm)	38″ (965 mm)
Width (single wide)	42″ (1067 mm)	44″ (1118 mm)
Width (double)	48″ (1219 mm) total	50″ (1270 mm)
Thickness (residential)	1¾” (44 mm)	—
Thickness (commercial)	2¼” (57 mm)	—

The 2-inch allowance on the rough opening is a residential convention that provides room for jamb installation, shimming, and leveling. Commercial projects frequently use a 1-inch allowance or a custom dimension specified on the architectural drawings. International buyers should note that metric equivalents vary: a 2030 mm × 900 mm door is common in Europe and Asia, but it is not identical to the 36″ × 96″ North American specification. The difference is small—roughly 10 mm—but it matters when thresholds and frames are pre-drilled.

1.2 Standard vs. Custom: What “8-Foot” Actually Covers

An 8-foot door is tall enough that standard production methods hit their limits. Hinge placement, frame rigidity, and glass weight all change at this height.

Three hinges are the minimum at 8 feet. For doors exceeding 100 pounds, heavy-duty ball-bearing hinges or pivot systems are recommended. The frame must be reinforced at the hinge and strike locations—either with densified wood blocks or metal inserts—to prevent screw pull-out over years of use.

Weight is the hidden variable. A 36″ × 96″ solid wood door typically weighs 80–120 pounds depending on species and core construction. Glass lites add significant mass: a 36″ × 60″ insulated glass unit (IGU) can weigh 50–70 pounds on its own. Buyers who do not calculate total door weight before selecting hinges and closers will deal with sagging within the first year.

Tolerance standards vary by market. North American manufacturers typically reference NWWDA I.S. 1A or ASTM E2832 for dimensional tolerances. European buyers should expect compliance with EN 14351-1, which includes air permeability, water tightness, and wind load resistance classifications. These standards are not interchangeable—a door built to EN standards may not meet ASTM requirements for impact or structural performance, and vice versa.

2. Material Options for 8′ Front Doors

The four primary materials for 8′ front doors are solid wood, thermal-break aluminum, steel, and fiberglass. Each has distinct trade-offs in weight, insulation, maintenance, and cost that become more pronounced at 8 feet of height.

Material selection at this height is not about aesthetics alone. The engineering demands of a tall door—structural rigidity, thermal movement, moisture resistance—will expose weaknesses in materials that perform acceptably at 80 inches.

2.1 Solid Wood: Performance at Height

Solid wood remains the premium choice for residential entry doors, but the 8-foot height demands specific construction methods.

Engineered stile-and-rail construction is the industry standard for tall wood doors. The stiles (vertical frame members) and rails (horizontal members) are typically laminated from multiple layers of wood with opposing grain directions. This cross-lamination resists the warping that affects solid-slab doors at height. A door built from a single piece of solid wood will move with seasonal humidity changes—often enough to bind against the frame or pull the hinges loose.

Common species for 8-foot doors:

• Oak: Dense, durable, takes stain well. Heavy—expect 100+ pounds for a 36″ × 96″ slab.
• Mahogany: Stable, rot-resistant, popular for coastal projects. Slightly lighter than oak.
• Walnut: Premium appearance, good stability, higher cost.
• Engineered composites: Veneer over engineered wood core. Best dimensional stability per dollar.

Finish is non-negotiable at this size. Factory-applied UV-cured finishes provide a consistency that site finishing cannot match, particularly on tall doors where brush marks and drips become obvious at eye level. Buyers should specify the finish system in their order—not leave it to the factory’s discretion.

2.2 Aluminum Alloy / Thermal-Break Systems

Thermal-break aluminum is the dominant choice for commercial and high-performance residential applications. The “thermal break” refers to a polyamide or polyurethane strip that separates the interior and exterior aluminum profiles, interrupting the heat transfer path.

Performance metrics to request from suppliers:

• U-factor: 0.30–0.45 BTU/h·ft²·°F is typical for thermal-break systems with double glazing.
• Air infiltration: 0.06 cfm/ft² or better per AAMA/WDMA/CSA 101/I.S.2/A440.
• Water penetration resistance: Minimum 8 psf per AAMA testing protocols.
• Design pressure (DP) rating: 30–50 psf for residential, 50–70+ psf for commercial in wind-prone regions.

Multi-chamber profiles—typically 3 to 5 chambers—provide both thermal performance and structural rigidity. At 8 feet, the profile depth increases to prevent deflection under wind load. A standard residential aluminum door profile may be 2–3 inches deep; an 8-foot commercial unit often requires 3–5 inches.

Surface treatments matter for longevity. Powder coating per AAMA 2604 (architectural grade) or AAMA 2605 (superior grade) provides 20+ year finishes. Anodizing offers a metallic appearance but is less scratch-resistant. Wood-grain foil finishes are increasingly popular for residential projects that want the look of wood with the performance of aluminum.

2.3 Steel and Fiberglass: The Mid-Range Workhorses

Steel doors use 24-gauge or 22-gauge steel skins over an insulated foam core. They are secure, affordable, and dimensionally stable—but they dent, and the skin conducts heat despite the insulated core. At 8 feet, a steel door’s weight increases significantly: a 36″ × 96″ steel door with a foam core typically weighs 90–110 pounds.

Fiberglass doors are the compromise option. They do not dent like steel, do not warp like wood, and resist moisture better than either. The surface can mimic wood grain convincingly. Fiberglass is particularly strong in coastal climates where salt air corrodes steel and moisture destroys poor-quality wood.

Material	Weight (36″×96″)	Insulation (R-value)	Maintenance	Cost Range (per unit)	Typical Lifespan
Solid Wood	80–120 lbs	R-2 to R-5	High (refinish every 2–5 yrs)	$800–$3,000	30+ years with care
Thermal-Break Aluminum	60–90 lbs	R-7 to R-11 (with IGU)	Low	$1,200–$4,000	40+ years
Steel	90–110 lbs	R-5 to R-10	Low (but dents)	$400–$1,200	20–30 years
Fiberglass	60–90 lbs	R-7 to R-12	Very low	$600–$1,800	30+ years

The imperfect insight here is that cost does not map linearly to performance. A mid-range fiberglass door can outperform a premium solid wood door in coastal environments, but it will never match wood’s aesthetic depth. Buyers must decide which failure mode they can tolerate—warping, denting, or corrosion—before they choose a material.

3. Glass, Hardware, and Glazing Options

At 8 feet, glass configuration significantly affects door weight, thermal performance, and security. Double-pane insulated glass is the minimum standard; triple-pane and laminated impact glass are specified for extreme climates.

3.1 Glass Configurations for 8′ Doors

Full-lite doors—where glass occupies 80% or more of the door surface—are popular for entryways that want maximum natural light. Half-lite designs place glass in the upper portion, leaving a solid lower panel for privacy and impact resistance. Sidelites flank the door and are often specified at matching heights.

Glazing options at 8 feet:

• Double-pane IGU: Two panes with an air or argon gap. This is the minimum standard for energy-efficient construction.
• Triple-pane IGU: Three panes, typically with two gas-filled gaps. Used in cold climates where heating costs justify the premium.
• Low-E coatings: A microscopically thin metallic coating that reflects infrared radiation while transmitting visible light. Specify the coating’s solar heat gain coefficient (SHGC) based on your climate zone.
• Tempered glass: Heat-treated for strength. Breaks into small, relatively harmless pieces. Required for safety glazing in most jurisdictions.
• Laminated glass: Two panes bonded with a PVB interlayer. Holds together when broken, providing security and impact resistance. Required for hurricane-rated doors.

Safety glazing is not optional. The International Building Code (IBC) Section 2406 and ANSI Z97.1 specify where safety glazing is required—and a full-lite entry door is almost always within the regulated zone. Buyers should verify that the factory’s glass supplier provides certification documentation with each shipment.

3.2 Hardware Requirements at 8-Foot Height

The hardware schedule for an 8-foot door differs from standard-height doors in specific ways:

• Hinges: Minimum three per door. For doors over 100 pounds, specify heavy-duty ball-bearing hinges (5-knuckle) or pivot hinges rated for the door’s weight. Standard residential hinges (3.5″ × 3.5″) are insufficient.
• Multi-point locking: A 2-point or 4-point locking system engages multiple latches along the door edge. This prevents the door from warping at height and improves security. For 8-foot doors, a 4-point system is recommended.
• Door closers: Required for commercial applications. For residential, a closer is recommended if the door is exposed to wind or if children are present. Specify adjustable backcheck to control opening speed.
• Weatherstripping: At 8 feet, the door-to-frame seal has more linear footage—and more opportunity for air leakage. Specify compression seals (silicone or EPDM) rather than adhesive-backed foam, which degrades within 2–3 years.
• Thresholds: Adjustable thresholds allow fine-tuning of the door-to-floor seal. For commercial projects, check ADA compliance: the threshold height cannot exceed 1/2 inch for most applications.

4. Building Codes, Wind Loads, and Performance Testing

8′ front doors must comply with local building codes covering egress, energy performance, and structural integrity. For wind-prone regions, impact-rated glass and reinforced frames are mandatory, not optional.

4.1 Code Compliance for 8′ Front Doors

The International Building Code (IBC) and International Residential Code (IRC) establish baseline requirements for entry doors. Buyers should verify which code cycle their project falls under—2018, 2021, or 2024—as energy requirements become stricter with each revision.

Key code considerations:

• Egress: Residential egress doors must provide a clear opening of at least 32 inches wide and 80 inches high. An 8-foot door easily meets the height requirement, but the clear opening width (not the slab width) is what matters—a 36-inch slab with thick jambs may reduce the clear opening to 34 inches.
• Fire ratings: Commercial projects may require 20-minute, 45-minute, or 90-minute fire-rated doors. At 8 feet, fire-rated doors require specialized cores and hardware. The frame and seals matter as much as the door slab itself—a non-rated frame will compromise an otherwise rated door.
• Energy codes: IECC 2021 sets maximum U-factors for doors based on climate zone. For Zone 4 and colder, the maximum U-factor is typically 0.30–0.35. This effectively requires thermal-break aluminum or insulated fiberglass/steel—solid wood doors without insulation will not comply.

4.2 Wind Load and Impact Resistance

For projects in hurricane-prone regions—Florida, the Gulf Coast, the Caribbean—wind load and impact resistance are the defining specifications.

Miami-Dade County protocols are the strictest in the United States and have become the de facto benchmark for high-velocity hurricane zones (HVHZ). Doors must pass:

• ASTM E1886/E1996: Impact testing with a 9-pound 2×4 projectile at 50 feet per second, followed by 9,000 cycles of pressure cycling.
• ASTM E330: Structural testing under positive and negative design pressure.
• AAMA/WDMA/CSA 101/I.S.2/A440: The North American performance standard for windows and doors, which includes air, water, and structural ratings.

The design pressure rating is the number buyers need to specify. A DP30 rating means the door withstands 30 pounds per square foot of wind pressure. For a 36″ × 96″ door, that translates to roughly 720 pounds of total force—which is why the frame and anchoring system matter as much as the glass.

Buyers should request test reports before committing to a supplier. A factory that cannot provide ASTM or AAMA test reports for its 8-foot products is not a viable supplier for wind-rated projects. Period.

5. A Procurement Framework for 8′ Front Doors

Effective procurement of 8′ front doors requires documented specifications, a clear evaluation of factory capabilities, and a pre-shipment inspection plan. Buyers who skip these steps accept avoidable risk.

5.1 Defining Your Project Requirements Before Sourcing

The single most common mistake in door procurement is ordering before the specification is complete. A complete door specification includes:

• Door height and width (slab dimensions, not rough opening)
• Thickness (1¾” residential or 2¼” commercial)
• Material and construction (solid wood species, aluminum profile system, steel gauge, fiberglass type)
• Glass specification (glazing type, pane count, coating, safety rating)
• Hardware schedule (hinges, lockset, closer, threshold, weatherstripping)
• Performance ratings (U-factor, SHGC, DP rating, air infiltration)
• Fire rating (if applicable)
• Finish (stain color, paint spec, powder coat color, anodize type)
• Certification requirements (ASTM, AAMA, EN, CE, or regional equivalents)

Provide architectural elevations and section details to suppliers. A drawing communicates more in five minutes than a page of text can in an hour of back-and-forth.

5.2 Evaluating Suppliers: Factory vs. Distributor vs. Importer

Channel	MOQ	Unit Cost	Customization	Communication	Risk
Factory-direct	High (20+ units typical)	Lowest	Full	Direct, but requires logistics management	Higher (you manage the process)
Distributor	Low (1–5 units)	20–40% higher	Limited to catalog	Easy	Lower (local support)
Importer	Low	30–50% higher	None	Moderate	Medium (you depend on their sourcing)

Factory-direct is the right choice when you have a defined project pipeline, clear specifications, and the capacity to manage ocean freight and customs clearance. Distributors make sense for one-off projects or urgent replacements. Importers are rarely the best value for repeat buyers—you pay for their sourcing expertise without gaining direct control over quality.

5.3 Red Flags to Watch in Supplier Evaluation

• No test reports available. A factory that cannot produce ASTM, AAMA, or EN test reports for its products has not tested them.
• Vague lead times. A supplier who says “30–60 days” without specifying production and shipping separately is hiding uncertainty.
• No quality control process. Ask for their inspection checklist. If they cannot describe their QC process in detail, they do not have one.
• Sample quality differs from production quality. The sample is made by the most skilled craftsman with the most attention. Production runs are not—unless the factory has documented QC checkpoints.
• Unwillingness to provide documentation. Packing lists, proforma invoices, certificates of origin, and customs documents are standard. A supplier who hesitates on documentation will create problems at your port.

5.4 Quality Control and Inspection Checklist

Before shipment, verify:

• Dimensions: Measure height, width, and thickness at multiple points. Tolerance should be within ±1/16″ (1.5 mm) for slab dimensions.
• Squareness: Measure diagonal lengths. They should match within 1/8″ (3 mm).
• Glass seal integrity: Inspect the IGU for seal defects, condensation between panes, or edge damage.
• Hardware function: Open and close each door. Check that locks engage smoothly and hinges operate without binding.
• Finish consistency: Inspect under good lighting for runs, sags, or color variation.
• Packaging: Wood crates or heavy-duty cardboard with foam corner protection. Moisture barrier for ocean freight is non-negotiable.

5.5 Questions to Ask Before Ordering

• What are your standard production tolerances for 8-foot doors?
• Can you provide test reports for air infiltration, water penetration, and structural wind load?
• What is your MOQ for custom 8-foot doors?
• What is your lead time for production and for shipping to my port?
• How do you package doors for ocean freight?
• What documentation do you provide with each shipment?
• What is your process for handling defects discovered after delivery?

5.6 Decision Guide: Choose A If… Choose B If…

Choose a factory-direct supplier if: You have a defined project pipeline, clear specifications, the capacity to manage logistics, and you need competitive pricing at scale.

Choose a distributor if: You need one or two doors quickly, you value local support over price, and you are willing to accept catalog-standard products.

Choose a custom manufacturer with OEM/ODM capabilities if: You need proprietary designs, private labeling, or doors that meet specific performance requirements not available in standard catalogs.

Frequently Asked Questions

Q1: Is an 8′ front door a standard size or custom?

An 8-foot (96-inch) door height is considered a standard tall size in many markets, but widths, thicknesses, and configurations vary. Most factories offer 8′ as a standard production height, with custom widths and designs available. The key is confirming that the factory’s production line can handle the tolerances required at this height—not every facility has the machinery or QC processes for tall doors.

Q2: How much does an 8′ front door weigh?

A 36″ × 96″ solid wood door typically weighs 80–120 pounds depending on species and core. Aluminum and fiberglass options are lighter at 60–90 pounds, while steel doors with insulated cores fall in the 90–110 pound range. Add 50–70 pounds for a large insulated glass lite. This total weight determines hinge requirements and whether a door closer is needed.

Q3: What is the rough opening for an 8′ front door?

For a 36″ × 96″ slab, the rough opening is typically 38″ × 98″ (add 2 inches to both width and height). Commercial projects may require different allowances based on frame type and floor conditions. Always confirm with your supplier’s installation guide—guessing this dimension is the fastest way to create a field-fabrication problem.

Q4: Can an 8′ front door meet hurricane wind load requirements?

Yes—but only if the door is engineered with reinforced frames, impact-rated glass, and tested to standards like ASTM E1886/E1996 (Miami-Dade protocols) or ASTM E330 for structural wind load. Ask your supplier for test reports specific to your project’s design pressure rating. A door that meets DP30 is not automatically rated for DP50.

Q5: What is the lead time for factory-ordered 8′ front doors?

Typical lead times range from 15–45 days depending on material, quantity, and customization level. Solid wood doors with custom finishes take longer than standard aluminum or steel units. Confirm lead times and shipping schedules before placing an order—and add 20–30 days for ocean freight if you are importing.

Q6: Can I order 8′ front doors with OEM branding?

Yes—most factories offering OEM/ODM services can produce doors with your branding, custom packaging, and private label documentation. This is common for distributors and importers who need their own product line. Specify your branding requirements in the initial inquiry so the factory can confirm they can accommodate your packaging and labeling needs.

Q7: How do I verify a door supplier’s credentials?

Ask for: (1) test reports for air infiltration, water penetration, and structural wind load, (2) certification documents (ISO 9001:2015, CE, AAMA, or regional equivalents), (3) a detailed quality control checklist, and (4) references from buyers in your market. A factory that cannot provide these documents is not a viable long-term supplier.

8. Production Process: From Raw Material to Finished Door

Understanding how a door is actually manufactured helps buyers distinguish between factories that assemble components and factories that control the entire production process.

8.1 Wood Door Production

For solid wood doors, the process begins with lumber selection and conditioning. Kiln-dried lumber is acclimated to the factory environment to reach a moisture content of 6–10%—the range that prevents warping and cracking in most climates.

Components are cut to size using CNC machining centers. Stile-and-rail joints are cut with precision tolerances measured in fractions of a millimeter. The core is assembled with adhesive and pressed under hydraulic pressure—typically 100–200 psi for 30–60 minutes depending on the adhesive system.

After pressing, the door is sanded to a smooth surface, then finished. Factory-applied UV-cured finishes are applied in multiple coats, with sanding between coats. The finished door is inspected under controlled lighting for surface defects, then wrapped in protective film and stored in a climate-controlled area until packaging.

8.2 Aluminum Door Production

Aluminum doors begin with extrusion—aluminum billets are heated and forced through dies to create the profile shapes. The extruded profiles are cut to length, and the thermal break is inserted. The polyamide strip is crimped or injected, then the profile is milled for hardware, drainage, and glazing.

Surface treatment follows: powder coating or anodizing. Powder coating involves electrostatic application of dry powder, followed by curing in an oven at approximately 200°C. AAMA 2604 and 2605 specifications dictate minimum coating thickness and performance requirements.

Glass is cut, tempered, and assembled into IGUs in a controlled environment. The glass unit is sealed with structural silicone, then installed into the door frame with setting blocks and gaskets.

8.3 Assembly and Final Inspection

The final assembly stage brings together the door slab, frame, glass, and hardware. At this point, the door is tested for function: opening, closing, locking. Air and water infiltration tests are performed on sample units from each production batch.

The finished door is packaged for shipment. Wood crates or heavy-duty cardboard with foam corner protection are standard for ocean freight. A moisture barrier is applied to protect against condensation during transit—this is the step the Ohio buyer’s supplier skipped.

9. Quality Control: Our Multi-Stage Inspection Process

Quality control at a door factory is not a single inspection at the end of the line. It is a series of checkpoints that catch defects before they compound.

Our inspection process includes:

• Incoming material inspection: Lumber is checked for moisture content and defects. Aluminum profiles are checked for dimension and surface quality. Glass is inspected for chips, scratches, and seal integrity.
• In-process inspection: During machining, dimensions are verified at each cutting stage. Assembly is checked for squareness and joint quality.
• Pre-finish inspection: Before finishing, the door is inspected for surface defects that would be visible after coating.
• Post-finish inspection: Finished doors are inspected under controlled lighting for finish consistency, runs, and color matching.
• Functional testing: Sample units from each batch undergo air infiltration, water penetration, and wind load testing per applicable standards.
• Pre-shipment inspection: Every door is checked for dimensions, squareness, hardware function, and packaging integrity before loading.

This multi-stage approach catches defects early—when they are cheap to fix—rather than after the door is crated and loaded onto a ship.

10. Customization and OEM/ODM Options

For B2B buyers, the ability to customize doors to project specifications is often the deciding factor in supplier selection.

10.1 What Can Be Customized

• Dimensions: Height, width, thickness—within structural limits.
• Material: Wood species, aluminum profile system, composite construction.
• Glass: Pane count, coating, safety rating, decorative options.
• Hardware: Lockset brand and model, hinge type, closer, threshold.
• Finish: Stain color, paint spec, powder coat color, anodize type.
• Design: Panel configurations, glass shapes, transom combinations.

10.2 OEM and Private Label

OEM (Original Equipment Manufacturing) means the factory produces doors to your specifications, under your brand. This is the standard model for distributors and importers who want their own product line.

Private label extends this to branding: your logo on the door, your packaging design, your documentation. The factory handles production and quality control while you handle sales and distribution.

For construction projects, OEM capabilities are essential when the architectural specification is non-standard. A factory that can only produce catalog models will force you to compromise on the spec—and the compromise will surface during the building inspection.

11. Ordering Process: MOQ, Lead Time, and Shipping

11.1 Minimum Order Quantity (MOQ)

MOQ varies by product type and customization level. Standard aluminum doors may have a lower MOQ than custom solid wood doors, which require specific lumber procurement.

For 8-foot front doors, expect:

• Standard aluminum or steel: MOQ of 10–20 units
• Custom solid wood: MOQ of 5–10 units, depending on species and finish
• OEM production: MOQ of 20–50 units, depending on complexity

11.2 Lead Time

Production lead time for 8-foot doors:

• Aluminum doors: 15–25 days
• Fiberglass or steel doors: 15–30 days
• Solid wood doors: 25–45 days (custom finishes add 5–10 days)

Add 20–30 days for ocean freight to North American ports, 25–35 days to European ports. Air freight is available for urgent orders but is cost-prohibitive for door quantities.

11.3 Shipping Options

FCL (Full Container Load) is the most cost-effective for orders exceeding 20–30 doors, depending on size. LCL (Less than Container Load) is available for smaller orders but incurs higher per-unit freight costs and longer transit times due to consolidation.

The factory’s role includes:

• Packing: Wood crates or heavy-duty cardboard with foam protection
• Documentation: Packing list, proforma invoice, bill of lading, certificate of origin
• Customs clearance: Assistance with export documentation; the buyer’s customs broker handles import clearance

12. Case Study: Bulk Supply for a Caribbean Resort Project

A Caribbean resort developer approached us in early 2024 with a requirement for 120 thermal-break aluminum entry doors, including 8-foot units for ground-floor suites. The specification required Miami-Dade impact ratings, a specific powder coat color, and multi-point locking systems.

The project timeline was 90 days from order to installation. Our production schedule allocated 30 days for manufacturing, 10 days for quality control and testing, and 20 days for ocean freight to the Caribbean port.

The key challenge was the impact rating. We provided test reports from our aluminum door systems demonstrating compliance with ASTM E1886/E1996. The developer’s architect verified the reports against the project specification, and production proceeded.

Doors were shipped in a single FCL with custom crating designed for the resort’s on-site handling equipment. The developer’s project manager reported zero damaged units on arrival and successful installation across all 120 doors.
