Greenhouse Aluminum Fittings

Greenhouse Aluminum Fittings are precision-engineered extruded alloy components that connect, seal, and reinforce the Greenhouse Main Frame. As critical auxiliary parts of modern greenhouses, they ensure structural stability, waterproof sealing, and easy assembly while enhancing the overall durability and service life of the greenhouse. Made of high-strength aluminum alloy, these fittings feature lightweight, anti-corrosion, and weather-resistant properties, widely used in glass greenhouses, polycarbonate (PC) sheet greenhouses, and multi-span film greenhouses. They are essential for building high-efficiency, low-maintenance agricultural cultivation facilities.

The main material for greenhouse aluminum fittings is 6063-T5 aluminum alloy, processed by hot extrusion and anodizing. This material has a high strength-to-weight ratio, natural corrosion resistance, and excellent machinability. The surface is treated with anodizing or powder coating to form a dense protective layer, effectively resisting oxidation, rainwater erosion, and chemical corrosion from fertilizers and pesticides. Compared with steel fittings, aluminum fittings are 60% lighter, reducing the overall load on the greenhouse frame and foundation. Their smooth surface prevents damage to covering materials like glass or PC sheets, ensuring sealing integrity.
