Top 10 Aluminium Inside Doors Manufacturer & Factories

Traditional wood and engineered timber products (HDF/MDF) possess organic hygroscopic structures that expand, warp, and host mold when exposed to relative humidity fluctuations above 60% (common in tropical regions, coastal projects, spas, and hospital wet areas). Extruded aluminium (Alloy 6063) features zero water absorption, zero swelling, zero VOC emissions, and complete structural immutability under severe temperature/moisture gradients. When coated with Qualicoat-certified powder coatings or Class AA25 anodizing, aluminium doors deliver a maintenance-free service life exceeding 25 years without delamination or finish peeling.

Yes. Acoustic performance in aluminium inside doors is achieved through engineered damping rather than mass alone. DERCHI utilizes multi-chambered internal profiles fitted with heavy multi-layer EPDM cellular rubber gaskets along the perimeter rebates. Glazing units utilize acoustic PVB (polyvinyl butyral) or SGP laminated safety glass (e.g., 5mm + 0.76mm acoustic PVB + 5mm). At the bottom threshold, an automatic mechanical drop-down seal engages automatically when the door closes against the jamb, completely closing the undercut acoustic gap and delivering verified acoustic damping from STC 38 up to STC 42 dB.

Concealed flush-wall aluminium frames require strict rough opening tolerances of ±3mm plumb and square across vertical and horizontal planes. Specifiers should incorporate a two-piece aluminium sub-frame system: the primary structural base frame is mechanically fastened to the masonry or steel-stud opening prior to plasterboard or dry-wall installation. Once finishing coats, wall claddings, or paint are completed, the finished decorative casing and door leaf are secured using 3D-adjustable internal cam screws, ensuring perfect 2.5mm perimeter visual reveals without exposed fixings.

Quality protection begins at the extrusion line. All anodized or PVDF-coated surfaces receive a co-extruded, low-tack protective polymer film that remains in place throughout CNC machining, assembly, and on-site construction. Finished doors are individually wrapped in 5-layer shock-absorbing pearl foam, sealed with moisture-barrier polyethylene wrap, protected with high-density corrugated edge protectors, and secured within fumigated custom plywood crates engineered with internal steel reinforcing bands. Crates are loaded using dedicated container ramp dollies to prevent forklift punctures during maritime transit.

Upon receipt of your architectural door schedule and floor plans, DERCHI's in-house engineering team generates complete 2D/3D CAD shop drawings within 24 to 48 hours for consultant approval. Following sign-off and prototype approval (if required), standard mass production for a 200–500 unit custom interior door package requires 25 to 30 calendar days at our 180,000 m² Foshan facility. Pre-hung factory assembly and comprehensive multi-station quality inspections (verifying latch alignment, anodizing thickness, and squareness) are completed prior to export crating.
