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

| CONSTRUCTION STAGE SERVICE 1,Offering specific construction drawings and process the fabrication: We offer specific construction drawings, clearly indicating every dimension and connection detail. Meanwhile, we closely monitor the fabrication process, implementing quality control measures at each step.
2,Offering guidance and instructions for installing with detailed drawing:
We provide the service of sending technicians to construction sites. Equipped with detailed installation drawings, they offer on - the - spot guidance and instructions. |   |
  | After-Sale Service 1,For utilization, we offer advice on optimizing the load - bearing capacity of steel structures according to different usage scenarios and suggest appropriate equipment layout in industrial workshops. 2,Regarding maintenance, our team provides guidance on routine maintenance tasks like regular rust - prevention treatments. We recommend the use of anti - rust coatings and cleaning methods to extend the service life of steel components. |
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.
