The steel structure system has comprehensive advantages such as light weight, factory manufacturing, fast installation, short construction period, good seismic performance, fast investment recovery, and less environmental pollution. Compared with reinforced concrete structures, it has more advantages in the development of "high, large, and light" aspects. Steel structures are widely and reasonably used in the field of construction engineering, especially in developed countries and regions. The steel structure industry is usually divided into five subcategories: light steel structures, high-rise steel structures, residential steel structures, spatial steel structures, and bridge steel structures.
characteristic
1. High material strength and light weight;
Steel has high strength and elastic modulus. Compared with concrete and wood, the ratio of density to yield strength is relatively low. Therefore, under the same stress conditions, the components of steel structures have small cross-sections, light self weight, are easy to transport and install, and are suitable for structures with large spans, high heights, and load-bearing capacity.
2. Steel has toughness, good plasticity, uniform material, and high structural reliability;
3. High degree of mechanization in steel structure manufacturing and installation;
4. The steel structure has good sealing performance;
5. Steel structures are heat-resistant but not fire-resistant;
6. Poor corrosion resistance of steel structures;
7. Low carbon, energy-saving, green, and reusable.
Reasonable cost
The basic cost has been reduced, and the construction speed is still relatively fast. It can be completed and put into operation as soon as possible, and the comprehensive economic benefits are greatly better than concrete structure buildings. Industrial production plants are being constructed in full swing in various regions, and steel structure plants have the advantages of beautiful and elegant appearance, diverse building shapes, high color, high degree of industrialization in steel component production, low cost, short construction period, simple installation and construction, flexible layout, light weight of steel, convenient material design and calculation, and recyclability, making steel structures widely used in modern industrial plants.
Post maintenance and upkeep
1. Sandblasting for rust removal. It is to use compressed air pressure and continuously use quartz sand or iron sand to remove the rust on the surface of steel structures, clean up oil and impurities, and only expose the original color.
2. If it is manual rust removal, choose some rust removal tools, such as sandcloth, wire brush, knife, etc., to clean the rust.
3. To use acid pickling for rust removal, the steel structure needs to be immersed in an acid bath. If the steel rusts, it will shorten its service life. The method of acid cleaning can effectively remove the impurities. Remember to rinse with clean water after acid cleaning.
