High-Performance Four-Season Sunroom Engineering

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.

  • Thermal Break IsolationPA66 polyamide insulation strips prevent thermal bridge heat loss and frame sweating.
  • Heavy-Gauge Structural FramingPrimary roof beams feature up to 3.5mm wall thickness with optional inner steel stiffeners.
  • Laminated Roof GlazingImpact-resistant double tempered laminated Low-E glass guarantees overhead safety.
  • Concealed Drainage GuttersHigh-capacity internal rain channels prevent water backing up into wall assemblies.

Manufacturing Standards

B2B Quality Control & Global Delivery Process

How Primor Metal Door Co., Ltd. ensures flawless assembly and zero site delays for international buyers.

01

1. 3D CAD Shop Drawings

Our engineers convert your architectural sketches into precise 3D CAD models, verifying beam spans, drainage pitches, and wall attachment points prior to cutting.

02

2. Precision CNC Machining

Profiles are processed on 5-axis CNC machining centers to ensure exact corner miter cuts, structural joint mortises, and pre-drilled fastener channels.

03

3. Trial Pre-Assembly

Every structural sunroom frame undergoes complete trial assembly and water tightness testing at our factory floor before disassembly and packaging.

04

4. Export Crate Packing

Structural beams and glass units are labeled per opening drawing and packed in fully sealed steel-belted wooden crates for ocean freight protection.

Procurement FAQ

Frequently Asked Questions

Direct answers for architects, general contractors, and importers preparing custom sunroom specifications.

Can Primor custom engineer sunrooms for heavy snow load and hurricane wind zones?

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.

What glazing options are available for four-season thermal break sunrooms?

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.

How does Primor Metal Door Co., Ltd. ensure precision fit for overseas B2B orders?

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.

What surface finishes are recommended for coastal locations?

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.
