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.

Product Description

Material & Craftsmanship

Cast Aluminum Art Board: Large-area integral cast aluminum board covering the entire door face — relief patterns cast in a single pour with high surface flatness and pattern consistency, presenting the perfect union of industrial precision and handcrafted artistry.

Steel Bulletproof Interior: Specialized ballistic steel plate serves as the core load-bearing layer within the door body — quench heat-treated for combined hardness and toughness, effectively resisting ballistic impact.

Aluminum Honeycomb Buffer Interlayer: Aviation-grade aluminum honeycomb fills between the cast aluminum board and steel plate, forming an "aluminum board – honeycomb – steel plate" sandwich structure that progressively absorbs impact energy.

Fluorocarbon Board Coating: Fluorocarbon spray process optimized for large-area cast aluminum boards — uniform finish without colour deviation, consistent lustre across the entire board for a cohesive, commanding visual effect.

Bronzed Copper Board Rendering: Large-area copper rendering is extremely challenging — achieved through zone-spraying + manual blending technique ensuring natural copper tone transitions and rich layering across the entire board.

304 Stainless Steel Door Sill: Brushed/mirror stainless steel sill unified in style with the cast aluminum board — details demonstrating the coordination and refinement of the overall design.
