Do you export entry doors to India, Pakistan, Bangladesh and Sri Lanka?

Yes. We supply villa owners, builders, architects and distributors across South Asia, including India, Pakistan, Bangladesh, Sri Lanka, Nepal and the Maldives, with quotations on FOB or CIF terms to major regional ports such as Nhava Sheva, Mundra, Chennai, Karachi, Chittagong and Colombo.

Which entry door material is best for coastal and monsoon regions?

For coastal cities with salt-laden air, stainless steel and cast aluminum doors with corrosion-resistant finishes perform best. For heavy monsoon rainfall, choose a door with multi-point locking, compression gaskets and a drained threshold. Unlike solid timber, metal doors do not swell, warp or attract termites in high humidity.

Can you customise the door size and design, including Vastu preferences?

Yes. Every door is made to order. Our engineers provide free CAD shop drawings and can adjust width, height, pivot position, opening direction, panel pattern, colour and wood-grain finish to match your architectural drawings and Vastu-based layout preferences.

What certifications do DERCHI doors hold?

Our products are tested and certified to international standards including CE, ISO 9001, AS 2047 and UL fire ratings, backed by 8 international certifications and more than 30 design and technology patents.

What information do I need to send for an accurate quotation?

Please share the finished opening size, door material, preferred design or reference photo, colour and finish, lock and hardware requirements, quantity, destination port or city, and your project timeline. Architectural drawings help us quote faster.

How are doors packed and supported after delivery?

Doors are protected with surface film, foam corners and reinforced export crates for long-distance sea freight. Each shipment includes installation instructions, and our English-speaking engineers provide remote installation guidance and after-sales support.

Strategic Sourcing Intelligence

Future Procurement Trends Reshaping the Global Aluminium Door Market

Procurement executives, commercial developers, and façade consultants are shifting from price-per-square-meter transactional models to holistic whole-life carbon and structural endurance frameworks.

1. Low-Carbon Billet Traceability & EPD Mandates

International commercial tenders now mandate Environmental Product Declarations (EPD). Tier-1 buyers prioritize manufacturers utilizing hydro-powered primary aluminium smelting with carbon intensities below 4.0 kg CO2e/kg Al, coupled with closed-loop factory scrap reclamation.

2. Consolidation of Fenestration Supply Chains

Procuring entities are discarding multi-vendor fragmented models. Sourcing entrance pivot systems, automated overhead rolling shutters, curtain walls, and terrace bi-folds from a single consolidated OEM mitigates interface mismatch, warranty disputes, and ocean freight logistics overhead.

3. Stringent Extreme-Weather Codification

Due to intensifying global climatic anomalies, project owners in coastal zones demand proven hurricane-impact engineering (such as AS 2047 N6, Florida Miami-Dade NOA, and ASTM E1886/E1996 missile-impact ratings) to safeguard high-capital infrastructure against structural failures.

Engineering R&D Horizons

Technological Innovations in Modern Aluminium Door Systems

The technical boundary between aesthetic lightness and industrial-strength performance is expanding through innovations in profile geometry, metallurgy, and smart automation.

Ultra-Narrow Sightlines with Concealed Sub-Frames

Architectural trends demand invisible frame configurations. OEM extrusion design is achieving sightline margins below 25mm while relocating load-bearing hardware to concealed perimeter channels, enabling maximum glass-to-wall ratios without structural deflection.

Intelligent Mechatronics & Smart Building Integration

Modern entrance doors now ship factory-prewired with concealed multi-point motorized latching mechanisms, biometric access units, and integrated RS485/BACnet protocols for automated communication with Central Building Management Systems (BMS).

Multi-Cavity Thermal Decoupling & Aerogel Cores

To meet strict net-zero envelope mandates (Passivhaus standards with overall Uw values ≤ 0.8 W/m²K), profiles utilize continuous multi-stage thermal breaks injected with aerogel or high-density polyisocyanurate (PIR) foam inserts to stop thermal bridging completely.

Procurement Knowledge Base

Frequently Asked Questions for B2B Importers & Contractors

Technical and commercial clarifications covering engineering tolerances, alloy specifications, export containerization, and warranty governance.

What aluminium alloys and tempers do you utilize for structural doors?

We exclusively process primary 6063 and 6061 aluminium alloy billets. For standard architectural fenestration, 6063-T5/T6 is specified for its exceptional extrusion precision and anodizing surface quality. For oversized commercial pivot doors or high-wind load roll-up guide channels, we utilize structural 6061-T6 or 6005A alloys, ensuring yield strengths exceed 240 MPa.

How do you guarantee weather tightness in cyclonic or heavy monsoon regions?

Our assemblies incorporate multi-point compression cam-locks coupled with continuous, co-extruded vulcanized EPDM gaskets. Thresholds are custom-engineered with multi-stage cascade drainage weep-holes and stainless steel back-check valves that prevent hydrostatic back-pressure and wind-driven water ingress during pressures up to 700 Pa.

Can you support custom architectural dies and extrusion profile development?

Yes. Our in-house tooling center develops bespoke extrusion dies based on client CAD/BIM specifications. The standard prototyping timeline for custom profile dies is 12 to 18 business days, followed by CMM laser dimensional validation and sample cross-section extrusion before initiating mass production.

What surface finish treatments are available for extreme marine environments?

For coastal zones within 5 km of seawater, we offer fluorocarbon PVDF finishes (minimum 3-coat, 70% Kynar 500 resin base, film thickness ≥ 40 μm) and Class 25 hard-anodized finishes (≥ 25 μm) complying with AAMA 2605 specifications. These coatings withstand 3,000+ hours of continuous neutral salt spray (ASTM B117) without blistering or adhesion failure.

What are your ocean freight export packaging and damage mitigation standards?

Every door frame and sash is wrapped in protective, residue-free PE film, edged with high-density EPE foam corner guards, and hermetically sealed inside heat-treated, fumigated plywood crates (ISPM-15 compliant). Desiccant silica packs are inserted into each crate to neutralize condensation and humidity corrosion during long marine voyages.

What is your typical production lead time for multi-container OEM orders?

Standard production runs for configured catalog products average 25 to 30 days from final approved shop drawing sign-off and deposit receipt. Fully customized architectural extrusions or specialized hardware sourcing runs require 35 to 45 days. Emergency project staging and split-container deliveries can be scheduled upon commercial review.

What hardware brands and multi-point locking mechanisms do you integrate?

We partner with premier hardware engineering manufacturers globally, offering German Siegenia, Hoppe, GU, and Roto hardware suites, as well as high-grade custom stainless steel SUS304/SUS316 DERCHI proprietary multi-point assemblies. Smart mortise locks with biometric, RFID, and Tuya/Zigbee smart integration are available factory-fitted.

What warranty coverage is provided for international B2B shipments?

We provide a 10-year comprehensive structural warranty on all 6063-T5 aluminium profile extrusions, a 10-year warranty on PVDF surface coatings against peeling or fading, and a 5-year replacement warranty on mechanical hardware and motorized drive systems. Full replacement hardware kits are shipped air-express for any verified component defect.
