The bolt holes of the connecting parts shall be processed according to the relevant regulations. The accuracy of the bolt holes, the surface roughness of the hole wall, the allowable deviation of the hole diameter and the hole distance, etc. shall comply with the current national standard "Code for Construction Quality Acceptance of Steel Structure Engineering" GB50205. Regulation.

Steel structure has been more popular among people, but because the steel structure corrosion problem has been a problem in the industry, the material itself is poor corrosion resistance, heat resistance is not fire-resistant shortcomings, if the project application can not properly handle the steel structure corrosion and fire protection problems, will directly affect the safety and durability of the project. As the steel surface cladding after the steel structure corrosion and fire protection issues.

The main measures to improve the design of steel structures and the main points of installation technology

It is often heard that purlins, C-shaped steel, Z-shaped steel, and CZ-shaped steel are mentioned. In fact, they include C-shaped steel and Z-shaped steel, but both C-shaped steel and Z-shaped steel perform better than traditional steel products in practical applications.

Compared with the traditional plant, the new steel structure plant is increasingly used, why abandon the traditional plant and enable the new steel structure plant? Steel layout plant and what advantages?
