Cross post

 The cross column is a kind of steel that is combined by the cutting of multiple steel plate cutting machine, the web plate and the flange plate are set up and then corrected, cut, welded and assembled. The whole structure is first processed into H-shaped steel, an important structural column in the frame, and the steel structure cross column improves the overall construction efficiency of the steel structure site. It has the advantages of light weight, high rigidity, high strength, simple construction, corrosion resistance, easy installation, low maintenance cost, and can meet the requirements of different loads and different structural forms, and has a wide range of application prospects. The cross column of steel structure is a common component used to support the load of steel structure buildings. It is usually composed of four steel pipes, crossed together to form a cross shape, and each end of the pipe is connected to other members, thus forming an overall structure.

 The cross column has the following advantages:

 1, strong bearing capacity: due to the structure of the cross column, it has a high bearing capacity and can withstand a lot of pressure and tension. 

 2, lightweight: compared with the traditional concrete structure, the steel structure of the cross column is lighter, can reduce the weight of the building, improve the stability and durability of the structure. 

 3, convenient construction: the steel structure of the cross column is composed of multiple components, can be standardized manufacturing, greatly improving the efficiency of manufacturing and construction. 

 4, good sustainability: steel is a resource that can be recycled, steel structure of the cross column can not only reduce the generation of construction waste, but also meet the requirements of environmental protection and sustainability. 

 5, steel structure of the cross column also has some shortcomings, such as:

 6, the cost is relatively high: the price of steel is high, plus manufacturing, transportation, installation and other costs, the cost of steel structure of the cross column is relatively high. 

 7, vulnerable to environmental impact: steel is susceptible to oxidation and corrosion, if not protected, may affect its service life and carrying capacity.

 Construction requirements of steel structure cross column combination:

 1. Check the design drawings before construction to ensure the quality of construction; 

 2, check the quality of steel to ensure that the quality of steel meets the requirements of the drawing;

 3, according to the drawing requirements, according to the specified size of cutting;

 4, according to the drawing requirements, according to the specified size of welding;

 5. Check the splicing parts before installation to ensure the installation quality;

 6, mechanical inspection should be carried out after the completion of construction to ensure the safety of the structure;

 7, after installation should be painted to extend the service life.
