Do you supply entry doors to Southeast Asian countries?

Yes. DERCHI supplies importers, developers, contractors and villa owners across the Philippines, Vietnam, Thailand, Malaysia, Indonesia, Singapore and neighbouring markets, and exhibited at WORLDBEX 2025 in the Philippines.

Which entry door material is best for humid and coastal tropical climates?

Aluminum and stainless steel entry doors are preferred because they do not swell, warp or rot in high humidity. For beachfront projects we recommend corrosion-resistant finishes and stainless hardware; cast aluminum suits ornate villa main gates.

Are DERCHI doors suitable for typhoon-prone areas?

Our door and window systems have passed AS 2047 N6 testing, covering wind resistance, air and water tightness and durability. For each project we engineer the configuration to the wind load specified by your architect or local code.

Can you manufacture custom sizes such as large pivot doors?

Yes. Sizes, finishes, colours, glass and locking hardware are fully customisable, and our in-house engineering team provides free CAD shop drawings that match your door schedule.

Which certifications do your entry doors hold?

Products are tested and certified to CE, ISO 9001, AS 2047 and UL fire-rated standards, and the company holds more than 100 certificates and patents.

How do I start a door project with DERCHI?

Email info@derchisoutheastasia.com with your drawings or opening sizes, quantities, preferred material, project location and timeline. An English-speaking engineer will reply with a technical proposal.

Engineering White Paper Analysis

Structural Dynamics & The Anatomy of High-Performance Bay Windows

A bay window projection alters a building envelope’s aerodynamic and thermodynamic balance. Precision manufacturing from an accredited OEM/ODM factory ensures long-term structural integrity and zero envelope leakage.

Corner Mullion Load Transfer

Bay windows require heavy structural mullions at 90°, 135°, or customized angles. Our proprietary extruded 6063-T6 aluminum corner posts are engineered to handle high downward roof weight loads and severe lateral wind resistance (up to AS 2047 N6 criteria), eliminating sagging over multi-decade cycles.

Polyamide PA66 Thermal Breaks

Because bay windows extend outward, exposure to solar gain and ambient temperature differentials is heightened. We incorporate multi-chamber PA66 GF25 thermal barrier strips, achieving low U-values (≤ 1.4 W/m²K) to meet Canada standard energy codes and tropical heat condensation prevention requirements.

Dual-Drainage & EPDM Gasketing

Water intrusion is the number one cause of bay window installation failure. Our systems utilize pressure-equalized cascading drainage channels and vulcanized EPDM continuous sealing gaskets, guaranteeing Class 9A (600 Pa) watertightness under monsoon and hurricane wind pressures.

Procurement Due Diligence

Frequently Asked Questions by Commercial Buyers & Importers

Direct technical answers addressing structural calculation, sea freight protection, export compliance, and customized lead times.

How does the factory solve structural deflection in multi-angle bay windows?

Every custom aluminium bay window is engineered using structural finite element analysis (FEA). We employ heavy-gauge 6063-T6 aluminum internal steel-reinforced coupler mullions at all junction points (90°, 135°, or bespoke angles). This guarantees that dead loads from the ceiling or header lintel are safely bypassed around the glazing framework.

Are your window systems tested and approved for coastal hurricane zones?

Yes. Our systems comply with AS 2047 N6 (highest Australian cyclonic performance level) as well as North American Florida Hurricane Proof standards. We laminate tempered SGP/PVB interlayers into our insulated glass units, resisting both large missile impact and prolonged positive/negative cycling pressures.

What export packaging is used to protect three-dimensional bay window frames?

Bay window units possess 3D geometries vulnerable to shipping racking. We utilize multi-layer protective packaging consisting of surface protective film, EPE foam edge wraps, corner shock-absorbers, and fully enclosed IPPC-certified fumigation-free plywood crates with interior steel structural bracing to eliminate transit deformation.

Can DERCHI provide full CAD shop drawings and BIM models for architectural submittals?

Our internal engineering department supplies complimentary CAD shop drawings, anchoring details, interface flashing schematics, and Revit BIM models within 48 hours of receiving your window schedules or floor plans, allowing seamless integration into architectural submittal packages.

What surface coating warranties do you provide against coastal salt-spray corrosion?

We offer AkzoNobel or PPG fluorocarbon PVDF coating systems and 25μm architectural anodized finishes that exceed AAMA 2605 requirements. These finishes carry 15-to-25 year warranties against chalking, fading, cracking, and salt-air electrolytic corrosion in tropical coastal regions.

What is the standard production lead time for customized commercial project batches?

Standard custom production cycles range from 25 to 35 business days post-approval of shop drawings and glass specifications. For fast-track developments or phased projects, container schedules are staggered to match your construction timeline without site bottlenecking.
