Good Sealing Performance: The welded structure can be completely sealed, supporting products with good air tightness and water tightness, like high-pressure containers, large oil sumps, and pressure pipes.
Good Corrosion Resistance: General steel structures are derusted, galvanized or painted, and regularly maintained. For offshore platforms in seawater, special measures like "zinc block anode protection" are used.
Low carbon, Energy saving, Green and environmental, Material recycled: Steel structures generate minimal construction waste when demolished, 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.
