Buyer Support
Frequently Asked Questions
Technical guidance for B2B buyers, importers, contractors, and project managers procuring custom aluminum doors.
What custom aluminum door systems does Primor Metal Door Co., Ltd. manufacture?
Primor Metal Door Co., Ltd. specializes in engineered aluminum door systems including multi-panel bifold doors, heavy-duty multi-track sliding doors, thermal break casement doors, and architectural pivot entry doors built to exact project drawings.
What thermal break technology is used in Primor aluminum doors?
Our door profiles feature high-precision Polyamide (PA66) thermal barrier strips that isolate interior and exterior aluminum chambers. Combined with double or triple Low-E insulated glass units, this dramatically reduces thermal conductivity and meets stringent global energy efficiency codes.
How does Primor support commercial B2B projects and overseas procurement?
We provide end-to-end B2B project support including architectural drawing reviews, structural wind-load calculation, custom shop drawing approvals, factory-direct manufacturing, export-ready wooden crating, and complete shipping documentation for international buyers.
What finishes and glass options are available for custom door orders?
We offer AAMA-compliant powder coating (in custom RAL colors), fluorocarbon PVDF, anodized finishes, and realistic wood-grain textures. Glazing options include double or triple tempered safety glass, soundproofing acoustic laminates, tinted solar-control glass, and low-emissivity (Low-E) coatings.
