Steel structure engineering is a structure mainly made of steel. It is mainly composed of steel beams, steel columns, steel trusses and other components made of section steel and steel plates. The components or parts are usually connected by welds, bolts or rivets. It is one of the main types of building structures. Because of its light weight and simple construction, it is widely used in large factories, bridges, venues, super high-rise buildings and other fields.

1. Steel structure engineering shall avoid disassembly and assembly of inclined fulcrum;

2. Steel structure engineering shall avoid cutting steel structure by optical fiber laser or opening holes on it. If holes are opened as far as possible, appropriate structural reinforcement and preventive measures shall be taken;

3. Avoid steel member deformation caused by violent building construction;

4. Do not touch the steel anchor screw. Whether it is loosened or tightened, it will change the bearing capacity of the original structure;

5. Avoid welding other components on the existing steel structure. If welding as much as possible, certain reasonable countermeasures shall be adopted in the project construction process, such as cooling a part near the welding part with a wet towel;

6. Avoid hanging on steel beams and steel columns at will. Do not build walls at will and expand the load.

7. Generally, the surface of steel structure will be painted with fireproof coating. Fireproof coating is the most important natural barrier to ensure the re installation of steel structure in case of safety accident. Try to protect the fireproof coating as much as possible. If it is damaged, it needs to be repaired immediately.
