Explore our top-tier catalog of interior doors, acoustic partitions, thermal break sliding systems, and security closures manufactured for prime residential, commercial, and hospitality developments worldwide.
Ranked among the Top 10 premium door and window brands in China, Guangdong Dejiyoupin Doors and Windows Co., Ltd. (DERCHI) is an internationally acknowledged manufacturer delivering complete high-performance architectural systems worldwide.
Fully compliant with CE, ISO 9001, AS 2047 (N6 Rated), NFRC, and UL fire standards. Our submittal-ready compliance packages minimize project permitting delays across North America, the GCC, Australia, and the EU.
From internal aluminum flush doors, slim-frame glass partitions, and tambour closures to oversized pivot entry doors and hurricane sliding assemblies, our single-source factory model radically reduces site coordination friction.
Every project receives complete architectural support: shop drawings, structural wind-load calculations, jamb details, and finish customisation with dedicated English-fluent sales engineers responding within 24 hours.
Global architectural demands are shifting toward ultra-minimalist geometries, rigorous acoustic isolation, and life-cycle sustainability. Here is where the sector is headed through 2030.
Modern interior specifications demand flush floor-to-ceiling profiles that blend seamlessly into drywall. Concealed sub-frames, hidden hinges, and zero-rebate magnetic latches are quickly replacing conventional surface architraves in high-end developments.
As open-concept layouts evolve, internal acoustic compartmentalization is paramount. High-performance aluminum internal doors now incorporate multi-chamber extruded profiles, perimeter drop-down automatic seals, and laminated acoustic glazing to ensure acoustic privacy.
Developers targeting LEED Platinum and BREEAM certifications require aluminum with verified recycled content (post-consumer billeting) and fluorocarbon powder-coating free of VOC emissions, ensuring sustainable lifecycle performance without sacrificing corrosion resistance.
Selecting the appropriate door system requires balancing structural span, ambient moisture exposure, and cycle testing benchmarks.

How our smart manufacturing process transforms raw 6063-T6 aluminum ingots into millimetre-precise architectural openings.
Conventional screws fatigue over high-traffic cycles. Our 180,000㎡ plant utilizes multi-axis CNC machines and pneumatic hydraulic corner-crimping injected with German two-component structural resin, guaranteeing lifelong mitre squareness and anti-sag resilience.
Internal architectural doors now feature quiet magnetic tongue locks that retract completely when open, preventing latch plate scraping. Profiles are pre-milled for flush-mounted biometric sensors, smart building automation (RS485/Zigbee), and electric strikes.
Using advanced Italian vertical fluorocarbon anodizing and 3D wood-grain sublimation, our aluminum internal profiles offer velvety matte finishes resistant to fingerprints, chemical cleaners, scratch wear, and high indoor humidity levels.
Critical technical considerations for architects, quantity surveyors, and project developers when sourcing aluminum internal doors directly from our factory.
Aluminum doors offer zero warping, swelling, or cracking when exposed to variable HVAC levels or coastal humidity. They provide superior strength-to-weight ratios for tall ceiling openings (up to 3.5m+), require zero maintenance repainting, and achieve higher fire and acoustic performance ratings.
We do not force standard sizes. Clients provide their project door schedule and architectural floor plans. Our engineering department develops 1:1 shop CAD drawings specifying sub-frame allowances, finished floor clearance (FFL), and wall depth adjustments for final sign-off before profile extrusion cutting.
DERCHI products hold CE, ISO 9001, Australian AS 2047 (N6 cyclone rating test passed), North American NFRC ratings, and UL fire-rated certifications. Comprehensive submittal packs including mechanical endurance and acoustic laboratory test reports are provided directly for engineering consultant approvals.
Every door panel undergoes multi-layer protection: protective surface films, custom corner guards, pearl cotton wrapping, sealed vacuum barrier bags, and containment within fully enclosed fumigated solid plywood crates with desiccant packs to prevent moisture condensation and shifting during international transit.
