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.

Technical Whitepaper

Engineering Pocket Door Systems for Next-Generation Architecture

Analyzing structural evolution, sliding kinetics, and procurement shifts shaping commercial and luxury residential fenestration specifications.

Flush-Integrated Recessed Cassettes

Conventional pocket doors suffered from structural buckling inside the rough opening wall cavity. Modern engineering emphasizes reinforced galvanized steel and extruded aluminum split-stud wall cassettes. These pre-assembled structural cages absorb lateral drywall stresses, preventing binding against the moving glass panels even in high-traffic commercial suites.

Thermal Decoupling & Acoustic Barrier

Interior-to-exterior transitions require continuous polyamide PA66 glass-fiber thermal breaks. By decoupling the interior aluminum fascia from the external ambient exposure, condensation is mitigated, and overall heat gain (SHGC) drops drastically. Combined with dual-chamber EPDM wiper seals, sound transmission ratings frequently surpass STC 38.

Magnetic Levitation & Soft Dampers

Heavy triple-glazed doors weighing up to 400 kg demand advanced kinetics. Leading architectural suppliers integrate carbon-bearing roller carriages, hydraulic bidirectional soft-close pistons, and even contactless magnetic linear motor tracks. These mechanisms ensure effortless fingertip actuation and silent gliding inside wall recesses.

Slim Sightlines & Concealed Thresholds

Architects worldwide increasingly mandate minimal visual profiles. Engineering trends prioritize ultra-narrow stiles (as low as 20mm interlock faces) that completely vanish within perimeter jamb pockets. Recessed flush-floor guide tracks eliminate physical trip hazards while incorporating hidden drain channels that handle extreme wind-driven rainfall.

Prefabricated Modular Sourcing

On-site pocket door construction is notorious for high labor costs and misalignments. The industrial trend leans heavily toward factory pre-hung cassette systems. Delivered fully plumbed, squared, and glazed from our automated Foshan facility, these modular units reduce general contractor installation schedules by up to 60% on multi-unit high-rise projects.

Sustainable Lifecycle & Low-Carbon Metallurgy

With corporate ESG commitments dominating international hospitality builds, aluminum pocket doors formulated with recycled secondary billet drastically diminish project embodied carbon. Fluorocarbon (PVDF) surface treatments deliver a 25-year service life against severe UV degradation and maritime moisture, maximizing whole-life capital value.

Aluminium Pocket Doors: B2B Sourcing FAQ

Addressing the critical engineering, shipping, tolerance, and installation questions faced by commercial procurement heads, quantity surveyors, and developers.

What are the wall cavity tolerance requirements for heavy aluminum pocket door cassettes? ▼

For standard monolithic or double-glazed aluminum pocket door systems, our structural steel-reinforced cassette requires a minimum rough wall pocket thickness ranging from 100mm to 150mm depending on leaf profile depth. Finished plumb line tolerances must be kept within ±2mm across the entire horizontal overhead track length to prevent uneven roller friction and ensure completely true slide-in travel without panel wobble.

How do you achieve acoustic isolation with pocket sliding doors? ▼

Unlike hinged swing doors that seal firmly against perimeter stops, sliding pocket doors require specialized edge sealing. We implement perimeter nylon acoustic brush strips paired with active drop-down mechanical rubber thresholds. Upon full pocket closure, these gaskets automatically compress against the finished floor and perimeter jambs, eliminating sound leakage and boosting sound transmission class ratings up to STC 35-40 with laminated acoustic PVB glass.

Can pocket doors withstand monsoon wind loads when used on exterior patios? ▼

Yes. Exterior-grade aluminum pocket doors utilize heavy-duty multi-chamber extruded profiles (2.0mm to 3.0mm wall thickness) engineered with internal steel rebar reinforcement. We design integrated sub-sill drain trays fitted with one-way weep valves. When tested to ASTM E330 and AS 2047 criteria, our systems withstand high positive and negative cyclonic pressures without structural deflection or interior water bypass.

What are typical production lead times and FOB/CIF shipping schedules? ▼

Standard production turnaround for bespoke architectural orders is approximately 25 to 35 calendar days following final CAD drawing approval and glass specification sign-off. Ocean transit schedules from Foshan or Shenzhen ports vary by destination: 12-16 days to South Asian ports (e.g., Nhava Sheva, Colombo), 22-28 days to the Middle East, and 28-35 days to European or North American deep-water harbors. Full container load (FCL) consolidation options are supported.

Can the overhead track and roller carriages be serviced after wall closing? ▼

Absolutely. Every DERCHI pocket door frame includes an engineered removable ceiling trim stop. This allows facility maintenance engineers to inspect, lubricate, adjust leaf leveling, or entirely replace roller assemblies without damaging the adjacent drywall, plasterwork, or structural wall cladding.

Do your pocket doors integrate with smart hotel access and automation systems? ▼

Yes. We integrate concealed magnetic electromagnetic hold-open locks, keycard access terminals, and low-voltage brushless DC motor overhead track actuators. These systems integrate smoothly into building automation (BMS), KNX smart home protocols, or hotel room master controllers for fully contactless, motorized pocket sliding operation.
