Galvanized C Purlins Product Advantages

Strong anti-corrosion ability

The surface adopts hot-dip galvanizing process, which has strong corrosion resistance and is suitable for harsh environments such as humidity and high corrosion.

Lightweight and high-strength

Light weight, reducing structural load, and at the same time has high bending strength (cold bending processing), strong bearing capacity.

Excellent cross-sectional performance

C-shaped cross-sectional design, excellent bending performance in the vertical direction, effectively bearing roof/wall loads, and ensuring structural stability.

Easy installation

Can be customized by cutting, punching, etc., and fixed on site by bolts, purlins or welding, with a short construction period and no need for large equipment.

Wide applicability

The choice of different coating thicknesses meets the anti-corrosion requirements of different projects; the choice of different materials (such as Q195/Q235/Q345, etc.) meets the strength requirements of different projects.

Galvanized C Purlins Applications

• Construction: roof/wall support for steel structure factories, warehouses, gymnasiums and stations, etc., used with color steel plates or sandwich panels.
• Agricultural buildings: frames for greenhouses and breeding sheds, structural support for agricultural product storage warehouses, etc.
• Temporary buildings: steel structures for folding container houses, modular container houses, expandable container houses, etc.
• Other applications: photovoltaic brackets, indoor and outdoor decoration racks, display racks, etc.; skeleton structures for supermarkets, exhibition halls, and canopies.

• Strictly select high-quality raw materials, multiple advanced processing equipment, the product cutting surface is flat, smooth and burr-free, and the appearance quality is high.
• The product has high strength, strong corrosion resistance, large bearing capacity, long service life, strict factory quality inspection, reliable quality and stable performance.
• Complete specifications and sufficient inventory can quickly match the C purlins and supporting products you need according to your needs, and support customized specifications.
