Multi-story Steel Structure Applications

Multi-story steel structures are increasingly popular for commercial and residential projects due to their strength and versatility. The inherent strength of steel allows for taller buildings with fewer support columns, creating more usable space and architecturally appealing designs.

These structures demonstrate excellent resistance to natural disasters including earthquakes and hurricanes. Steel's flexibility enables it to absorb impact from strong winds, while its durability ensures long-term performance with minimal maintenance requirements.

Product Application
Light Frame Steel Construction Hangar Design Prefabricated Steel Structure Factory Building Workshop warehouse
A pre-engineered steel building is a modern technology where the complete designing is done at the factory and the building components are brought to the site and then fixed/jointed at the site, all is bolt connection, no need any welding!
An efficiently designed pre-engineered building can be lighter than the conventional steel buildings by up to 30%. Lighter weight equates to less steel and potential price savings in structural framework.
