Lanying new factory steel structure workshop building
Steel structures are widely used in the construction industry because of their high material strength and light weight.
In this article, we will explore the benefits of using steel structures.
1. High material strength and light weight
Steel has high strength and high elastic modulus. Compared with concrete and wood, its density to yield strength ratio is relatively low. Therefore, under the same stress conditions, the steel structure has a small cross-section and light weight, which is easy to transport and install. It is suitable for structures with large spans, high heights and heavy loads.
2. Steel has good toughness, plasticity, uniform material and high structural reliability
Suitable for bearing impact and dynamic loads, with good seismic resistance. The internal structure of steel is uniform and close to isotropic homogeneous body. The actual working performance of steel structure is more in line with calculation theory. Therefore, the steel structure has high reliability.
3. High degree of mechanization in steel structure manufacturing and installation
Steel structure components are easy to manufacture in factories and assemble on site. The finished products of mechanized steel structure components manufactured in factories are of high precision, high production efficiency, fast assembly speed on site and short construction period. Steel structure is a structure with the highest degree of industrialization.
4. Good sealing performance of steel structure
Since the welded structure can be completely sealed, it can be made into high-pressure containers, large oil pools, pressure pipes, etc. with good airtightness and watertightness.
5. Steel structure is heat-resistant but not fire-resistant
When the temperature is below 150℃, the properties of steel change little. Therefore, steel structure is suitable for hot workshops, but when the surface of the structure is subjected to heat radiation of about 150℃, it should be protected by heat insulation boards. When the temperature is 300℃-400℃, the strength and elastic modulus of steel are significantly reduced. When the temperature is around 600℃, the strength of steel tends to zero. In buildings with special fire protection requirements, steel structures must be protected by refractory materials to improve the fire resistance level.
6. Poor corrosion resistance of steel structure
Especially in humid and corrosive media environments, it is easy to rust. Generally, steel structures need to be rust-proofed, galvanized or painted, and maintained regularly. For offshore platform structures in seawater, special measures such as "zinc block anode protection" are required to prevent corrosion.
7. Low carbon, energy-saving, green and environmentally friendly, reusable
The demolition of steel structure buildings will hardly generate construction waste, and the steel can be recycled and reused.
