Primor Metal Door Co., Ltd. specializes in engineering and manufacturing structural thermal break aluminum sunrooms tailored for luxury residential villas, resort dining expansions, and commercial property extensions.
Unlike off-the-shelf prefabricated kits, every sunroom produced by Primor Metal Door Co., Ltd. is calculated and fabricated according to site-specific climate conditions. By integrating heavy-gauge 6063-T6 aluminum extrusion profiles with multi-chamber polyamide (PA66) thermal barrier strips, our sunroom systems deliver exceptional structural rigidity, airtight thermal separation, and year-round indoor climate comfort.
Select the roof profile and glass enclosure style that matches your project elevations and spatial layouts.
Featuring a double-pitched roof structure, gable sunrooms create dramatic vaulted ceilings with maximum daylight infiltration. Ideal for freestanding garden suites and primary house extensions.
A modern mono-pitch enclosure attached directly to the existing wall facade. Provides seamless architectural integration for villa backyards, restaurant terraces, and hotel lounges.
Engineered for high-wind urban rooftop environments and commercial venues. Combines structural curtain wall mullions with high-strength thermal break frames for expansive open views.
Combines heavy-duty insulated louvered roof panels with perimeter glass sliding or folding walls, offering total shading flexibility during summer and full wind sealing in winter.
Designed to meet strict international building standards, Primor Metal Door Co., Ltd. supplies complete technical engineering documentation for project approval.

How Primor Metal Door Co., Ltd. ensures flawless assembly and zero site delays for international buyers.
Our engineers convert your architectural sketches into precise 3D CAD models, verifying beam spans, drainage pitches, and wall attachment points prior to cutting.
Profiles are processed on 5-axis CNC machining centers to ensure exact corner miter cuts, structural joint mortises, and pre-drilled fastener channels.
Every structural sunroom frame undergoes complete trial assembly and water tightness testing at our factory floor before disassembly and packaging.
Structural beams and glass units are labeled per opening drawing and packed in fully sealed steel-belted wooden crates for ocean freight protection.
Direct answers for architects, general contractors, and importers preparing custom sunroom specifications.
Yes. Primor Metal Door Co., Ltd. engineers every aluminum sunroom according to site-specific wind pressure and snow load requirements. We utilize heavy-duty 6063-T6 aluminum extrusion profiles (3.0mm+ structural thickness) and internal steel re-enforcement where required.
Roof structures feature double-laminated Low-E safety glass (e.g., 6mm Low-E Tempered + 1.52PVB + 6mm Clear Tempered). Wall sections can be equipped with double or triple insulated Low-E glass units filled with argon gas for energy efficiency.
Our engineering team generates detailed 3D CAD shop drawings for sign-off prior to production. Profile components are pre-cut, CNC-machined, and trial-assembled in our plant before export crating.
For coastal environments within 3 km of seawater, we recommend AAMA 2605 compliant PVDF fluorocarbon coatings or marine-grade anodized finishes to resist salt spray corrosion and color fading.
Send your architectural elevation drawings, opening dimensions, and climate requirements directly to our engineering project office.
