Primor Metal Door Co., Ltd. designs and manufactures custom aluminum windows, doors, pergolas and sunrooms for architects, builders, developers, dealers and importers.
Every order starts with your architectural drawings or window schedule. Our engineers check each opening for size, operation, glazing, hardware and local performance requirements, then issue shop drawings for approval. Only after sign-off do we cut, assemble and inspect the units, so what arrives on site matches what was specified.
Select a product type to see how it operates, where it performs best, and which Primor profile series it is built on.

Six reasons project teams choose a factory-direct partner over off-the-shelf suppliers.
Units are built to the exact rough opening on your drawings, including arches, trapezoids and oversize panels.
Polyamide-insulated profiles and insulated Low-E glass cut heat transfer and condensation in hot and cold climates.
Specify double or triple glazing, laminated safety glass for coastal zones, or acoustic glass for urban sites.
Powder-coated colors, wood-grain finishes and premium hardware matched across every window and door in the package.
See full-size products in five U.S. showrooms and get local guidance on selection, measurement and installation.
Units are labeled by opening, crated for container transport and shipped with the documents your import process needs.
A transparent five-step process designed for overseas buyers who need predictable results.
Send plans or a window schedule. We confirm sizes, operation and performance targets.
Recommended series, glass, finish and hardware for each opening, with clear options.
Detailed drawings and samples for your approval before production begins.
Precision cutting, assembly and inspection of every unit against approved drawings.
Opening-labeled crates, export documents and installation guidance for your team.
How Primor windows and doors perform in coastal, lakeside, garden and cold-climate settings.
Corner glazing with laminated glass and marine-grade finishes to withstand salt air while opening the view.
Coordinated casement doors and fixed lites for a continuous lake view.
Large sliding panels connecting the living room to the garden.
A shaded outdoor room that opens to the sky on demand.
Thermal break framing and Low-E glass keep the room comfortable through winter.
A quick reference our engineers use when recommending systems to first-time buyers.
Compression-sealed casements and laminated glass resist wind-driven rain and impact; choose marine-grade coatings.
Pair thermal break frames with Low-E triple glazing and warm-edge spacers to control energy loss and condensation.
Folding doors give the widest clear opening; sliding doors keep more glass and a slimmer look when closed.
Fixed lites maximize glass area; add awning or casement vents where ventilation is required by code.
Straight answers about customization, performance, lead preparation and delivery. Need more detail? Our full FAQ covers installation, warranties and maintenance.
Read the Full FAQYes. Every window and door is made to measure from your architectural drawings or window schedule. Our engineers review each opening, confirm sizes, operation, glazing and hardware, and issue shop drawings for your approval before production begins.
A thermal break window uses a low-conductivity polyamide strip to separate the interior and exterior aluminum profiles. This interrupts heat transfer through the frame, reduces condensation and, combined with insulated Low-E glass, significantly improves energy performance compared with non-thermal aluminum.
Send architectural drawings or a window and door schedule, the project location, preferred opening styles, frame color, glass requirements and any local code or wind-load requirements. With this information our team can prepare a technical proposal and shop drawings.
Yes. We work with architects, builders, developers, dealers and importers. Orders are protected with export packing and we coordinate shipping documentation to support delivery to your destination.
Product samples and full-size displays can be viewed at our U.S. showrooms in Los Angeles, the Bay Area, Houston, Dallas and Phoenix. Overseas buyers can also request profile samples and finish swatches.
Frames are available in powder-coated colors such as black, white, bronze and grey, plus wood-grain finishes. Glazing options include double or triple insulated glass, Low-E coatings, tempered and laminated safety glass, and decorative or privacy glass.
