Which certifications do DERCHI entry doors hold for export projects?

Our door systems are produced under an ISO 9001 quality system and have been tested for CE marking, AS2047 N6 (Australian wind, water and air performance), plus UL-referenced fire-rated constructions for pivot and commercial lobby doors. Test reports and certificates are released with the quotation package so your local building inspector can verify compliance before installation.

What is the maximum size for a single pivot entry door leaf?

Standard production covers leaves up to 1,600 mm wide and 3,200 mm high. For oversized villa gates and hotel lobby entrances we engineer leaves up to 2,000 mm x 4,000 mm using reinforced steel-core frames, heavy-duty floor pivots rated to 500 kg and multi-point hardware to control long-term deflection.

What is the typical lead time and MOQ for a custom entry door order?

Sampling takes 12-18 days. Bulk production is normally 25-35 days after drawing approval and deposit, depending on finish (powder coating, wood-grain transfer or PVDF). There is no fixed container MOQ for project orders; single-unit sample doors are accepted for showroom and testing purposes.

How are doors packed and protected for ocean freight?

Each leaf is wrapped in protective film, corner-guarded with EPE foam, sealed in a five-layer carton and fixed inside a fumigation-free plywood crate. Hardware and glazing beads are boxed separately and labelled per opening number, which keeps site sorting fast and reduces transit damage claims to below 0.3% of shipped units.

Do you provide CAD or BIM files and installation support?

Yes. Our in-house engineering team issues free CAD shop drawings, section details and BIM-ready blocks that match your door schedule, followed by installation manuals, torque and anchoring specifications and video-call guidance for the first openings on site.

Frequently Asked Questions (FAQ)

Can the cast aluminum door sizes and heraldic designs be customized?

Yes, we provide full custom services. You can customize the dimensions, heraldic motifs, surface finish colors (such as Royal Black or Bronzed Copper), and hardware components to perfectly match your architectural style.

Are these doors suitable for coastal or high-humidity climates?

Absolutely. Cast aluminum naturally possesses outstanding corrosion resistance and immunity to rust. Enhanced by our high-grade fluorocarbon finish, the door withstands coastal salt spray, acid rain, and extreme weather without degrading.

How does the bulletproof armoured core structure work?

The door utilizes a multi-layer composite structure consisting of a cast aluminum outer panel, high-strength inner steel plating, and an aluminum honeycomb buffer layer. Combined with multi-point locking systems, it offers certified bulletproof and anti-pry protection.

Why is aluminum honeycomb infilling better than traditional steel doors?

Aluminum honeycomb delivers structural rigidity and bulletproof integrity while reducing overall weight by over 30%. This prevents door leaf sagging over time, ensures smooth operation, and provides superior acoustic and thermal insulation.

What is the typical production and delivery timeline?

Following final design approval and measurement confirmation, custom factory production takes approximately 20 to 30 days. Doors are then packaged in reinforced wooden crates for safe global transport.

What warranties are included with the entry door?

We offer comprehensive warranty coverage: a 10-year warranty on the main door structure, 5 years on the surface finish, 3 years on the lock system, and 2 years on hardware accessories.
