Custom OEM Aluminum Entry Doors Suppliers & Exporters

DERCHI entry doors utilize virgin 6063-T5 or 6061-T6 structural architectural aluminum alloys. Unlike standard retail systems that utilize 1.2mm–1.4mm profile walls, our heavy-duty entry and large-format pivot frames feature structural wall gauges ranging from 2.5mm to 4.0mm at primary load-bearing web intersections. For cast aluminum security doors, our panels integrate solid vacuum-cast aluminum plates from 8.0mm to 12.0mm thick, yielding exceptional resistance against forced physical intrusion, torsional shear, and windward bending moments under severe windstorms.

We engineer products specifically matched to target geographic jurisdiction codes. For North American export, our assemblies can be engineered to fulfill Florida Building Code High Velocity Hurricane Zone (HVHZ) requirements using SentryGlas (SGP) laminated glass panels tested to large missile impact Level D. For thermal fenestration ratings, our multi-chambered polyamide profiles achieve required U-Factor and Solar Heat Gain Coefficient (SHGC) targets verified via NFRC-compliant simulation models. We also manufacture low-profile thermally broken ADA-compliant thresholds (≤ 1/2 inch) with beveled transitions for barrier-free commercial entryways.

Upon receipt of your architectural drawings, door schedules, or preliminary rough opening dimensions, our technical engineering office produces complete CAD shop drawings within 48 to 72 hours at no cost. These submittals detail head, jamb, and sill profiles, anchor bolt centerlines, thermal break geometry, glazing schedule, and finish callouts. Upon final sign-off, standard OEM extrusion and fabrication takes 25 to 35 business days, with expedited fast-track production available for critical project timelines.

Yes. Our automated vertical electrostatic powder-coating lines and anodizing baths offer full color customization. We support all RAL color palettes, fluorocarbon 3-coat metallic finishes, and hyper-realistic heat-transfer Italian woodgrain textures. Additionally, because we assemble our thermal break profiles in-house, we readily manufacture dual-color (bi-color) configurations—allowing specifiers to match an expressive dark bronze or textured cast facade exterior while maintaining a crisp matte white or natural timber aesthetic on the interior frame.

We partner directly with world-class hardware providers including Siegenia, Hoppe, Roto, Dormakaba, and FritsJurgens (for heavy-duty 500kg pivot systems). For automated access control, our doors support factory-integrated multi-point motorized mortise locks, electric strikes, concealed door closers with hold-open dampers, hidden biometric fingerprint or 3D face scanners, digital keypad entry handles, and hardwired relays compatible with commercial Crestron, Control4, or Savant home automation networks.

As an accommodating OEM/ODM manufacturer, we support commercial developers with multi-container bulk orders as well as custom home builders requiring bespoke single-villa entry door packages (MOQ is 1 set for custom pivot/luxury entry systems). All doors undergo rigorous 100% pre-assembly factory testing before being encased in protective foam film, perimeter honeycomb impact buffers, and secured within custom heavy-duty plywood export crates lined with steel bands. Packaging is certified for standard breakbulk and FCL/LCL ocean transit without requiring secondary transfer repacking.
