The steel structure is a structure composed of steel materials and is one of the main types of building structures. The structure is mainly composed of beam steel, steel column, steel truss and other members made of section steel and steel plate. It adopts silanization, pure manganese phosphating, washing and drying, galvanizing and other rust and rust prevention processes. Welds, bolts or rivets are usually used to connect the components or parts. Because of its light weight and easy construction, it is widely used in large factories, stadiums, super high-rises and other fields. The steel structure is easy to rust. Generally, the steel structure should be galvanized or painted, and it should be maintained regularly.
Features:
1. High material strength and light weight
Steel has high strength and high modulus of elasticity. Compared with concrete and wood, the ratio of density to yield strength is relatively low, so under the same stress conditions, the steel structure has a small cross-section, light weight, easy transportation and installation, suitable for large spans, high heights, and heavy loads Structure.
2. The steel has good toughness, good plasticity, uniform material and high structural reliability
Suitable for withstanding impact and dynamic loads, with good seismic performance. The internal structure of the steel is uniform, close to an isotropic homogeneous body. The actual working performance of the steel structure is more in line with the calculation theory. Therefore, the reliability of the steel structure is high.
3. High degree of mechanization in steel structure manufacturing and installation
Steel structural members are easy to manufacture in factories and assemble on site. The mechanized manufacturing of steel structure components in the factory has high precision, high production efficiency, fast assembly on site, and short construction period. Steel structure is the most industrialized structure.
