Rust-proof Galvanized C-Shaped Steel Purlins

Detalles Del Producto

C-shaped steel (C purlin) is a high-efficiency structural profile processed by cold bending. It has a “C”-shaped cross-section with a straight web and symmetrical rolled edges. Due to its excellent load-bearing performance, convenient installation, and high cost-effectiveness, it has become one of the preferred materials for roof purlins, wall beams, supporting frames, and auxiliary load-bearing components in steel structure buildings.

Features of C-shaped steel

Scientific cross-section, excellent stiffness

The rolled edge design of C-section steel significantly improves the bending stiffness and torsional resistance of the cross-section. Under the same self-weight, it can withstand a greater load than ordinary open profiles, making it suitable for conventional purlin arrangements with spans of 6–12 meters.

Flexible processing, convenient hole cutting

Elliptical or round holes can be pre-drilled at any position on the web according to design requirements, facilitating the installation of pipelines, tie rods, or self-tapping screws, reducing on-site secondary processing. The ends can be beveled for mitered or lap joints.

Material Compatibility with Multiple International Standards

Materials selected include Q235B, Q355B, S280GD+Z, S350GD+Z, and S450GD+Z, fully complying with international standards such as GB, EN 10346, ASTM A653, and JIS G3302. Hot-dip galvanizing, aluminized zinc (AZ), pre-painted, or anti-corrosion coatings are available, suitable for various corrosion levels from arid inland areas to high-salt-spray coastal areas (C5 environment).

Standardized Specifications and Complete Accessories

Common cross-sectional heights range from 80mm to 300mm, thicknesses from 1.5mm to 3.0mm, and lengths can be customized to project requirements (generally ≤12m, up to 15m for special cases). Combined with C-shaped steel connectors, diagonal bracing, and double-sided back-to-back composite components, a robust roof and wall cladding system can be constructed.

Lightweight and High-Strength, Highly Efficient Construction

The cold-bending process fully utilizes the yield strength of the steel, resulting in lower steel consumption for the same span compared to hot-rolled channel steel. Its lightweight nature reduces transportation and hoisting costs. Components are connected using self-tapping screws or bolts, enabling rapid installation and significantly shortening the construction period.

Earthquake and Wind Resistance, Safe and Reliable

The C-shaped steel purlin system, through a reasonable arrangement of tie rods and struts, effectively resists wind suction and seismic horizontal forces, meeting the structural safety requirements of international building codes (IBC, Eurocode 3, GB 50017, etc.).

Applications of C-shaped Steel

• Main and secondary purlins for roofs of steel structure factories, warehouses, and logistics centers;
• Horizontal walers for walls of industrial buildings, commercial showrooms, and stadiums;
• Frame support components for prefabricated houses, container houses, and light steel villas;
• Lightweight load-bearing components for the roofs of agricultural greenhouses and livestock sheds;
• Equipment support structures such as photovoltaic brackets, billboard joists, and conveyor supports.

Quality Control and Delivery

We strictly adhere to the ISO 9001:2015 quality management system, and dimensional tolerances conform to EN 1090 or ASTM C955 standards. Material certificates and coating thickness reports are available for each batch of steel.
