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.

There are no specific requirements for the service life of steel structures in the code, but in the structural design, according to the loaded code, the load statistical value of 50 years as the basic cycle is basically adopted, that is, the probability that the normal design steel structure will be damaged due to excessive load within 50 years is very small.

The installation of the steel structure needs to be hoisted first. Generally speaking, the middle is hoisted first, and then the outer side is hoisted. The principle of first going down and then up is adopted. Fix the middle part first and push through the ends. After being hoisted in place using tools, the anchor bolts are used to fasten them, and then the steel column bolts and pressure plates must be welded before the steel columns can be installed.

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?

Rust removal and coating of steel structures is a work easily ignored by steel structure contractors and is also a weak link in steel structure engineering construction. If this phenomenon is not corrected, it will have a great impact on the construction quality of the steel structure, because the quality of rust removal and painting will directly affect the maintenance cost of the steel structure during its future use, as well as the service life of the steel structure project, the safety of the structure, and the fire resistance time in case of fire (fire-resistant painting).
