Steel Purlins

Steel purlins are strip-shaped steel components in the roof or wall system of steel structure buildings, which are used to support roof panels and wall panels and transfer the loads of the roof or wall to the main frame structure.​

Detailed Introduction to Steel Purlins and Reasons for Choosing Them (Advantages of Steel Purlins)​

Why choose Steel Purlins​

High Strength and Light Self-weight: Made of steel, steel purlins have high strength themselves, which can bear various loads transmitted from the roof or wall, including wind load, snow load, self-weight, etc. At the same time, compared with some traditional purlin materials (such as wood), steel purlins have lighter self-weight. This not only reduces the burden on the main structure and lowers the cost of foundation engineering, but also reduces the seismic effect and improves the overall seismic performance of the building when disasters such as earthquakes occur.

Convenient Processing and Installation: Steel purlins can be produced in a standardized way in the factory, with high precision and fast production efficiency. At the construction site, through mature methods such as welding and bolt connection, they can be installed quickly and accurately. This prefabricated and convenient installation method greatly shortens the construction period of steel structure buildings, improves the construction efficiency, and at the same time reduces the difficulty of on-site construction and safety risks.​

Good Durability: After appropriate anti-corrosion treatment (such as hot-dip galvanizing, coating anti-corrosion paint, etc.), steel purlins have good corrosion resistance. They can maintain stable performance for a long time under different environmental conditions, including harsh environments with high humidity and corrosive gases, prolonging their own service life and reducing the later maintenance and replacement costs.​

Strong Design Flexibility: Steel purlins can flexibly adjust parameters such as cross-sectional shape, size and material according to different architectural design requirements. For example, for roofs with large spans, steel purlins with higher strength and larger cross-sectional size can be selected; for projects with special requirements on building appearance, the appearance of steel purlins can also be treated to meet the needs of architectural aesthetics.​

Recyclable: As steel products, steel purlins have high recyclability. When the steel structure building reaches its service life and needs to be demolished, steel purlins can be recycled and reprocessed for use, which conforms to the concept of green buildings and sustainable development. It can not only reduce the generation of construction waste, but also save resources.
