Manufacturer galvanized floor panels

Steel is characterized by high strength, light weight, good overall rigidity and strong deformation ability. Therefore, it is particularly suitable for the construction of large-span and ultra-high and ultra-heavy buildings. The material has good homogeneity and isotropy, and is an ideal elastomer. It complies with the basic assumptions of general engineering mechanics. The material has good plasticity and toughness, can undergo large deformation, and can withstand dynamic loads well. The construction period is short, its degree of industrialization is high, and it can carry out specialized production with a high degree of mechanization. Steel structures should study high-strength steel to greatly increase its yield point strength. In addition, new types of section steel should be rolled, such as section steel, also known as wide-flange section steel and shaped steel, and profiled steel plates, to meet the needs of long-span structures and super high-rise buildings.
Features
High material strength and light weight
Steel has high strength and high elastic modulus. Compared with concrete and wood, the ratio of its density to yield strength is relatively low. Therefore, under the same stress conditions, the steel structure has a small component section, light weight, easy transportation and installation, and is suitable for large spans, high heights, and heavy loads. Structure.
Steel has toughness, good plasticity, uniform material, and high structural reliability
It is suitable for withstanding impact and dynamic loads, and has good seismic resistance. The internal structure of steel is uniform and close to isotropic homogeneous body. The actual working performance of the steel structure is relatively consistent with the calculation theory. Therefore, the steel structure has high reliability.
Steel structure manufacturing and installation are highly mechanized
Steel structure components are easy to assemble at the factory manufacturing site. The factory mechanizes the finished steel structure components with high precision and high production efficiency, and the construction site assembly speed is fast and the construction period is short. Steel structure is the most industrialized structure.
The steel structure has good sealing performance
Since the welded structure can be completely sealed, it can be made into high-pressure vessels, large oil pools, pressure pipelines, etc. with good air tightness and water tightness.
Steel structure is heat-resistant but not fire-resistant
When the temperature is below ℃, the properties of steel change very little. Therefore, the steel structure is suitable for hot workshops, but when the surface of the structure is exposed to heat radiation of about ℃, it must be protected by heat insulation panels. When the temperature is around ℃, the strength and elastic modulus of the steel material decrease significantly. When the temperature is around ℃, the strength of the steel tends to zero. In buildings with special fire protection requirements, the steel structure must be protected with refractory materials to improve the fire resistance rating.
Steel structures have poor corrosion resistance
Especially in environments with humid and corrosive media, they are prone to rust. Generally, steel structures need to be derusted, galvanized or painted, and must be maintained regularly. For offshore platform structures in seawater, special measures such as zinc block anode protection are required to prevent corrosion. []
Low-carbon, energy-saving, green, environmentally friendly, and reusable
The demolition of steel structure buildings will produce almost no construction waste, and the steel can be recycled and reused.
