Among building structures, steel structures have good earthquake resistance and have a high degree of industrial production. The steel structure construction period is short, and it has the advantages of energy saving, environmental protection, and good ductility. Especially for steel structure buildings, its ductility can generate seismic waves. Attenuation effect to reduce earthquake damage to steel structure buildings. Steel purlins are suitable for all aspects of steel structure projects such as roofs and walls. The cross-section forms of purlins generally include C-shaped, Z-shaped, U-shaped, several-shaped steel, etc. Their function is to reduce the span of the cabin panel and fix the roof panel.
Features: Z-shaped steel has high support strength and is especially suitable for purlins on large-slope roofs.
Process: cold bending machine rolling.
Material: The raw material is hot-dip galvanized coil or steel strip, with thin wall, light weight, excellent cross-sectional performance and high strength. The product has a smooth surface, high dimensional accuracy, and is made of Q195-345 material.
Scope of application: used for roof and wall beams, door posts, etc. of steel structure buildings.
Model size: Height 80-400 Width 50-150 Folding 10-30 Thickness 1.5-4.0.

1. Building structure connection:
Z-shaped purlins are often used in the connecting parts of building structures. Their stable Z-shaped design allows them to withstand vertical and horizontal loads while maintaining structural stability and integrity.
2. Roof and wall systems:
As the main supporting structure of roofs and walls, Z-shaped purlins can effectively disperse and withstand pressure from the external environment, such as wind, rain, snow, etc.
Its efficient material utilization and lightweight features make building roof and wall systems more lightweight and flexible, while ensuring the strength and stability of the structure.
3. Industrial plants and warehouses:
In the construction of industrial plants and warehouses, Z-shaped purlins are often used to construct long-span roof and wall systems. Its good carrying capacity and stability can meet the space requirements of large industrial equipment.
Packaging introduction: Customized packaging according to drawings and requirements.
Service optimization: Packaging separately according to regional axis requirements;
Case: Nangang Industrial Park 3500㎡
