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: wall girt & roof purlin 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: structural purlin 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.

Galvanized C purlins price

Note: The above prices are FOB China port benchmark prices, based on Q235B steel, standard bundled packaging. Using Q345B high-strength steel will incur an additional charge of 18-25%.

Purchasing Tips

• Zinc Coating Selection: Z120 for dry environments; Z180 or higher is recommended for coastal, high-humidity, or industrial areas.
• Thickness and Strength: For every 0.2mm increase in thickness, load-bearing capacity increases by approximately 15%, but cost increases by 8-10%. Select the appropriate coating based on structural calculations to avoid over-design.
• Minimum Order Quantity and Delivery Time: The best unit price is available for standard specifications starting at 10 tons, with a production cycle of 10-18 days.
