About Welded Steel Structure Columns
Welded Architectural Structural Steel / Heavy Duty Structural Steel Columns offer exceptional strength-to-weight ratio, excellent rigidity, and superior deformation resistance. These properties make them ideal for large-span, ultra-high, and super-heavy building applications.
Key advantages include:
- Material homogeneity and isotropy that aligns with engineering mechanics principles
- Superior plasticity and toughness for withstanding dynamic loads
- Reduced construction timelines due to prefabrication
- High degree of industrialization and mechanized production
Our Manufacturing Capabilities
Our facility features three dedicated steel structure production lines equipped with:
- Flame cutting machines
- H-Section steel assembly machines
- Gantry welding machines
- Shot-blasting machines
- Paint spray booths
We maintain specialized workshop space for fabricating heavy-duty and large structural steel components.
