Welded Structural Steel Columns Q235B Q355B ASTM A36 Custom Sizes

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 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.
