Steel structure is the current popular building structure

The Chongqing steel structure project is the first of many buildings, and it is also a popular building structure in this century. However, if there is no protection, the life will be shortened, it can be affected by many external factors, and it will work longer, so that the steel can be used effectively to the maximum extent? Only two points can achieve the great efficiency of steel structure engineering. 1 Anti-rust technology is a key issue in the construction of steel structures. If the surface of the steel structure is not protected, it will be corroded by the action of the surrounding medium. Corrosion rate is related to ambient temperature, humidity and harmful substances. Common methods of preventing corrosion of components are chemical coatings such as spraying, corrosion resistant coatings, metallic coatings (eg galvanized) or phosphate treatment. Copper, chromium and nickel alloy steels for improved corrosion resistance. 2. Fire prevention of steel structure engineering is the main task of steel structure management. Steel is not flammable, but not fire resistant. The temperature will start to decrease significantly.C At 300°C, yield point, tensile strength, modulus of elasticity, temperature at 600°C, the strength of the steel is greatly reduced to I when the building is not subjected to any additional load. 3 Changzhi In the iron and steel industry, common fire-proof concrete bricks are cast around steel members or piles, and the surface coating contains asbestos materials and earthwork materials. When the surface of the steel structure is heated above 150 degrees for a long time, the insulating layer starts to protect the components from the heat. Both technologies must provide long-term protection of steel structures and part machining to extend the life of each steel structure. Chongqing steel structure is called 'green building'. 'Green' is the feature of future environmental and ecological protection. Start with green buildings.
