Solid Pine Sliding Barn Door
Solid pine and MDF interior sliding barn door with rustic K-brace design, 30–48 in. wide by 84 in. tall.
Product Overview
Our factory manufactures solid oak wood sliding barn doors with a manual top-mount sliding mechanism, designed for interior and light commercial use. The defining construction feature is the K-brace - a diagonal cross-brace pattern that stiffens the door panel against warping and sagging across wide spans, which is why this profile is commonly specified for bedroom and bathroom openings. The doors are available in three standard widths: 30 x 84 in., 36 x 84 in., and 48 x 84 in. Buyers sourcing for residential projects, hospitality fit-outs, and distribution programs will find the range covers most single-opening interior applications. 
What Makes This Product Different
Solid Oak Core, Not Hollow
The door is built from solid oak wood, a hardwood with a Janka hardness of 1360 lbf - dense enough to resist denting from daily contact and to hold screw and hinge points without crushing.
K-Brace Resists Warping
The diagonal K-brace layout adds cross-grain stiffness to a wide panel, reducing the seasonal movement that causes flat doors to bow or twist over time.
Three Stock Widths, 84 in. Height
30 x 84 in., 36 x 84 in., and 48 x 84 in. sizes cover standard single interior openings without custom tooling lead times.
Manual Sliding Operation
Manual top-hung sliding hardware keeps the mechanism simple, serviceable, and free of electrical components - a practical choice for wet or humid rooms such as bathrooms.
Finished Surface, Ready to Hang
Doors ship with a finished surface, so buyers avoid the sanding and sealing stage that raw timber panels require before fitting.

Key Performance Details
| Parameter | Performance Implication | Best For |
|---|---|---|
| Solid oak construction | Oak's density (approximately 0.75 g/cm³) and 1360 lbf Janka rating mean the panel resists impact damage and holds fasteners securely over repeated use. | High-traffic interior openings in homes and hospitality rooms |
| K-brace geometry | The diagonal bracing interrupts the long grain run of a wide panel, which is the primary cause of bowing in flat slab doors. | Wide openings such as 48 in. doorways where flat panels are most prone to movement |
| Manual sliding closure | No motors, sensors, or wiring - fewer failure points and no electrical rough-in required at the opening. | Bathrooms, closets, and retrofit projects where power is unavailable at the header |
| Finished surface | The factory-applied finish removes a finishing stage from the job schedule and reduces on-site dust and VOC exposure. | Projects with tight handover dates or occupied-building renovations |
| 84 in. standard height | Matches common residential door height, so the door aligns with standard trim and casing without custom sizing. | Residential bedroom, bathroom, and closet openings |
Applications
| Industry | Use Case | Why This Product Fits |
|---|---|---|
| Residential interiors | Bedroom and bathroom doorways | The 30 in. and 36 in. widths match standard single-leaf openings, and the manual slide suits humid bathroom environments. |
| Hospitality and short-stay accommodation | Guest room and ensuite partitions | The rustic oak finish and K-brace profile suit design-led interiors, while the finished surface reduces refurbishment downtime between guests. |
| Retail and distribution | Stocked barn door range for resale | Three fixed sizes and a consistent finished surface allow distributors to hold a compact SKU range that covers most interior openings. |
How This Product Compares

| Core material | Solid oak wood | Hollow-core or composite panel |
| Panel stability | K-brace diagonal bracing | Flat slab without bracing |

| Mechanism | Manual sliding | Swing or automated sliding |
| Size coverage | 30, 36, 48 x 84 in. | Single size, custom order only |
Customization Options
Size and Dimension Adjustments
Width and height can be adjusted beyond the three standard sizes to suit specific opening dimensions, subject to panel stability limits for the K-brace layout.
Surface Finish and Color
Finish tones can be matched to a supplied sample or color reference so a batch aligns with a project's existing joinery.
Logo and Branding
Branding can be applied to the door face or packaging for private-label programs, using methods suited to a finished wood surface.
Bracing Pattern
The K-brace layout can be varied in orientation or spacing to produce different visual profiles while retaining cross-grain stiffness.
Packaging & Shipping
Doors are packed for export with corner and edge protection to guard the finished face against transit scuffing, and multiple units can be consolidated per pallet to reduce handling. Flat-packed or assembled configurations are available depending on order volume and destination. Buyers should confirm the receiving height and pallet access at the destination warehouse, since 84 in. panels require adequate clearance.
Why Work With Us
Solid Wood Door Production
Our factory manufactures solid oak door panels in-house, which keeps grain selection and brace alignment under direct production control rather than relying on outside panel suppliers.
Fixed Size Range, Repeatable Output
Producing the same 30, 36, and 48 x 84 in. formats repeatedly means consistent dimensions across reorders, which matters for distributors restocking a catalogued SKU.
OEM and Private Label
Custom sizing, finish matching, and branding are handled as part of the production run, so private-label programs do not require a separate finishing step.
Technical Support After Sale
Online technical support is available for questions on sizing, bracing orientation, and finish care once the doors are in the field.
