Structure
Steel Structure Characteristic
1. 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.
2. Good Corrosion Resistance:
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.
3. Low carbon, Energy saving, Green and environmental, Material
recycled:
The demolition of steel structures hardly generates construction
waste, and the steel can be recycled.
Our Advantages
Product Parameters
The components of the steel structure have small section, light
weight, easy to transport and installation, suitable for large
span, high height, heavy bearing structure.
Suitable for withstand impact and dynamic load, with good seismic
performance.The internal structure of steel is uniform with high
reliability.
Lightweight Steel Structures: Used for small to medium-sized
buildings such as warehouses, factories, hangar, and commercial
buildings. They are cost-effective, lightweight, and quick to
assemble.
Heavy Steel Structures: Suitable for large-scale buildings like
industrial factories, bridges, airports, and stations, these
structures have high load-bearing capacities.
Multi-story & High-rise Steel Structures: These are used in office
buildings, residential complexes, and mixed-use developments. They
offer seismic resistance and fast construction timelines.
