导读：Want to build a steel structure factory in a cold region? Here are four tips to help you build it be

Snow load resistance design:

The warehouse design in cold regions adopts a portal steel frame structure. The steel columns and roof beams are H-shaped steel. In addition to resisting standard dead loads and live loads, the steel frame should also consider additional snow loads. Therefore, the wing plates of the steel columns and roof beams must be enlarged and thickened, which can improve the strength of the steel frame to resist external loads and ensure the stability of the structure.

Windproof design:

Since wind load is also a key factor in cold regions’ design, the steel structure design of the warehouse needs to pay special attention to wind resistance. In the design, the appropriate roof purlins and wall purlins are selected according to the column spacing. The roof usually adopts Z-shaped purlins, which are directly overlapped with each other to improve the strength of the purlins.

Material selection:

This project selected 100mm thick polyurethane composite panels as roof and wall materials. Polyurethane composite panels have good thermal insulation, compression resistance, and weather resistance, which can effectively isolate the influence of extreme external temperatures and ensure the internal environment of the warehouse is suitable. At the same time, it is light in weight and can reduce the burden on the main structure.

Structural durability:

The durability of steel structures is another essential consideration. Under the climatic conditions of cold regions, steel is susceptible to corrosion, so anti-corrosion measures such as coating treatment and the use of galvanized steel are required. In addition, regular maintenance inspections are also necessary to ensure the long-term safe operation of the warehouse structure.
