Steel structure manufacturer: How about introducing steel structure engineering?

Steel structure manufacturer: How about introducing steel structure engineering? The selection of materials for steel structures is combined with the operation cost, and suitable raw materials are matched according to different market demands. If the regional environmental pollution is becoming more and more serious, the raw materials for roof enclosure structure should be combined with low-end plates to ensure the operation cost used in the middle and later periods.

Steel structure manufacturer: What details should be paid attention to in the renovation of steel structure engineering

The steel structure of the steel structure manufacturer shall be made of steel as the basic material, mainly composed of prefabricated components made of channel steel and thick steel plate, such as steel column, steel beam, steel pipe truss, etc. Prefabricated components or components are generally welded, screwed or riveted, and are one of the important types of building construction. Because of its light weight and simple construction, it is widely used in large factories, highway bridges, stadiums, multi-storey buildings and other industries. 1. Prevent the removal of inclined support points of steel structure works; 2. The steel structure works of the steel structure manufacturer shall avoid the steel structure of the optical fiber cutting machine or drilling holes on the steel structure as much as possible. If the hole edge is opened as far as possible, appropriate engineering reinforcement measures should be taken

Key points of steel structure construction in winter

The key points of steel structure construction in winter: 1. When transporting and transporting steel structures in winter, anti-skid measures shall be taken. The line stacking place shall be flat and firm, and there has never been a puddle, and the road surface shall not be frozen. When the prefabricated components of the same model and specification are stacked, the prefabricated components should be kept level, the base plate should be on the same vertical line, and the prefabricated components should be prevented from slipping. 2. Before the assembly of steel structure, in addition to the specific contents specified in the requirements under normal temperature, the quality of prefabricated components shall be systematically rechecked according to the requirements under negative temperature. Any prefabricated component deformation caused by missing inspection during transportation and stacking during the production process, and the error exceeds the requirements and endangers the assembly quality
