1. High strength and stability:
Steel has the characteristics of high strength and high toughness, which can withstand large loads and has good anti-seismic performance, ensuring the safety and stability of the building.
2. Short construction time:
The construction time of steel structure building is relatively short, which improves the construction efficiency and reduces the construction cost.
3. Energy saving and environmental protection:
Steel is recyclable material, which is in line with the concept of green building.
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.
