Light Steel Structure Warehouse Customized For Agricultural Application
Introduction, use and advantages of steel structure:
What is steel structure's character?
1. High Strength But Light Weight
Steel has high strength and high modulus of elasticity. Compared
with concrete and wood, the steel structure has a lighter weight.
So it is easier to transport and install. And it is obviously
better suitable for large spans, high rise, and heavy loads
structure.
2. More toughness, More plasticity, Material Uniform & More
reliable structure
Steel material is better to undertake impact and dynamic loads with
good seismic performance. Its internal structure is uniform, close
to an isotropic homogeneous body. The actual working performance
conforms to the calculation theory. Therefore, the reliability of
the steel structure is high.
3. High degree Installation Mechanization
Steel structural components are easy to manufacture in factory and
assemble on site. The mechanized manufacture has high precision
with high production efficiency. And it's fast assembled on site
with quick construction time. Steel structure is the most
industrialized structure.
4. Good Sealing Performance
The welded structure can be completely sealed. Therefore it support to be made into products with good air tightness and good water tightness, like the high-pressure container, the large oil sump and pressure pipes.
5. Heat-resistant But No fire-resistant
When the temperature is below 150 ºC, the steel properties almost
don't change. When the temperature is between 300 ºC and 400 ºC, the
steel strength and elastic modulus are significantly reduced. When
the temperature is around 600 ºC, the strength of the steel tends
to zero. So the steel structure surface should be protected with a heat insulation board. In the buildings required special fire protection, the steel structure must be protected with refractory materials
to improve the fire resistance level.
6. Poor Corrosion Resistance
Especially in the environment of moist and corrosive media, it is
easy to rust. The general steel structure should be derusted,
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, Material recycled
The demolition of steel structures hardly generates construction
waste, and the steel can be recycled.
