Product Details

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.

4. Good sealing performance of steel structure

Because the welded structure can be completely sealed, it can be made into a high-pressure container with good air tightness and good water tightness, a large oil sump, and pressure pipes.

5. The steel structure is heat-resistant but not fire-resistant

When the temperature is below 150 ℃, the steel properties change little. Therefore, the steel structure is suitable for the hot workshop, but when the surface of the structure is radiated by heat at about 150 ℃, it should be protected with a heat insulation board. When the temperature is between 300 ℃ and 400 ℃, the strength and elastic modulus of the steel are significantly reduced. When the temperature is around 600 ℃, 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 level.

6. Poor corrosion resistance of steel structure

Especially in the environment of moist and corrosive media, it is easy to rust. The general steel structure should be galvanized or painted, and should be regularly maintained. 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 environmental protection, reusable

The demolition of steel structures hardly generates construction waste, and the steel can be recycled.
