China Wholesale Aluminium Louvre Windows Factories & Suppliers

High-performance architectural louvres are specifically engineered to address water ingress and particle penetration. We employ custom extruded interlocking blade seals made from virgin EPDM and hollow-profile Santoprene that maintain elasticity across -30°C to +80°C. Internal side-jamb collection channels catch incidental water seepage under high wind loads, routing it outward through hidden drainage weep valves before it can contact the interior envelope.

For coastal sites within 1 km of saltwater or regions with extreme solar radiation (such as the Middle East, Southeast Asia, or Florida), we recommend either 25-micron Architectural Anodizing (Class 1) or a 3-coat 70% Fluorocarbon PVDF resin finish meeting AAMA 2605 standards. These coatings resist salt spray corrosion for over 3,000 hours in continuous laboratory testing and offer superior resistance against chalking and UV fading.

Yes. Our in-house R&D engineering division of 30+ specialists develops complete AutoCAD shop drawings, 3D structural connection details, and structural calculation sheets verifying frame deflection (L/175 or L/250 criteria) tailored to your project's specific wind pressure parameters (ULS and SLS) prior to cutting any profiles.

For standard extrusion systems and inventory architectural colors (such as anodized silver, matte black, or architectural bronze), our production lead time is typically 20 to 30 calendar days from shop drawing sign-off. For fully bespoke dies requiring custom aluminum extrusion molds, die manufacture and sample extrusion take approximately 14 days, followed by standard manufacturing. MOQs can be tailored to support commercial villa mockups or multi-container phases.

Every unit is protected by a 5-layer export protocol: first, profile surfaces are coated with peelable protective film; second, high-density polyethylene bubble foam wraps the frame perimeter; third, corrugated corner shields protect joinery; fourth, units are individually wrapped in waterproof barrier film; and fifth, entire orders are loaded inside fully enclosed, fumigated solid plywood crates or heavy-duty steel export racks engineered for zero-shift container shipping.
