Frequently Asked Questions

What does Level 8 air tightness mean for this door?

Level 8 air tightness per GB/T 7106-2008 indicates the door allows less than 0.5 m³/(m²·h) of air leakage at a pressure difference of 10 Pa. This is achieved through triple EPDM weatherstripping and precision-machined aluminum profiles, reducing drafts and improving HVAC efficiency in apartment settings.

Can the glass panels be replaced with opaque materials for privacy?

Yes, the multi-panel design allows substitution of tempered glass with aluminum panels, wood veneer inserts, or frosted glass. Customization of panel materials is available for specific privacy or aesthetic requirements without affecting the frame structure or air tightness rating.

Is this door suitable for coastal apartments with high humidity?

Yes, the 6063-T5 aluminum alloy frame is corrosion-resistant, and the electrophoretic coating provides additional protection against salt spray. The EPDM weatherstripping and polyamide thermal break also prevent condensation buildup, making it suitable for coastal environments.

What is the minimum order quantity for custom-sized doors?

For standard sizes, no minimum order quantity applies for sample orders. For fully custom dimensions and finishes, a minimum of 10 units per design is required to set up production tooling. Volume discounts are available for orders over 50 units.

How are the doors packaged for international shipping?

Each door is secured with foam padding, corner guards, and stretch wrap, then placed in a wooden crate with internal bracing to prevent movement during transit. The crates are stackable and designed to fit standard 20-foot or 40-foot containers. Lead time is 15-20 working days for FOB shipment.
