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.

Choose reasonable structural forms and materials, such as high-strength steel, and perform design calculations according to specifications.

The cross-sectional size, weld size, bolt spacing and diameter, etc. should meet the minimum requirements in the design requirements. For example, the steel pipe wall thickness is 3mm, the minimum steel plate thickness is 4mm, and the minimum cross-section of the angle steel is L45×4mm.

During the installation process, high-precision installation equipment and measuring instruments should be used to ensure the installation accuracy and stability of the components.
