Which entry door material performs best in humid, coastal Asian climates?

For tropical and coastal sites in Southeast Asia, aluminum and stainless steel entry doors are the most stable choices because they do not swell, warp or rot like timber. Powder-coated or fluorocarbon-finished aluminum resists humidity and salt air, while stainless steel offers maximum security with rust-proof durability.

Can DERCHI produce custom sizes such as oversized pivot doors and villa main gates?

Yes. Every door is made to order. Our in-house engineering team prepares free CAD shop drawings based on your opening sizes, door schedule, finish and hardware requirements before production starts.

Which certifications do DERCHI doors hold?

DERCHI products are tested and certified to standards including CE, ISO 9001, Australian AS 2047 and UL fire-rated certification, helping buyers pass local building inspections and project approvals.

How does DERCHI support buyers across Asia?

Our English-speaking sales engineers work in the GMT+8 time zone, the same business hours as most Southeast Asian markets. We support buyers from quotation and drawings to export packing, shipping from South China ports and installation guidance.
