Custom Structural Tubular Columns to ASTM A500 & A572 for Industrial and Commercial Buildings

Our custom structural tubular columns are precision-fabricated to ASTM A500 and ASTM A572, combining the geometric efficiency of hollow structural sections with the strength of high-strength low-alloy steel — delivering excellent compressive capacity, torsional rigidity and design versatility for industrial and commercial buildings.

1. Dual-Standard Advantage: ASTM A500 vs. ASTM A572

Understanding the difference between these two standards helps you specify the right column for each application.

Our engineering team helps you select the optimal standard based on load requirements, span, connection design and budget.

2. Engineered Sections & Structural Performance

Custom section profiles:

• • Round (CHS), square (SHS) and rectangular (RHS) hollow sections

• • Welded box sections fabricated from A572 plate for heavy-duty applications

• • Custom wall thicknesses and outer dimensions to optimise material use

• • Lengths up to transport limits, with splicing options for longer columns

• • Connection interfaces — base plates, cap plates, gusset plates, and bolted or welded splices

Structural performance under industrial & commercial loads:

• • Heavy axial compression from roof and floor loads

• • Bending moments induced by wind, seismic and eccentric loads

• • Fatigue cycles from equipment vibration or crane operations

• • Dynamic loads in industrial facilities and warehouses

• • Seismic events when designed to AISC 341 provisions

The closed-section geometry provides high torsional stiffness, making these columns ideal for moment frames and braced frames in both industrial and commercial buildings.

3. Factory Prefabrication Process – From Drawing to Delivery

• • Drawing Review: Structural requirements, connection details and tolerance needs confirmed

• • CNC Cutting & Drilling: Precise member lengths and bolt holes to AISC tolerances

• • Jig-Set Assembly: Consistent geometry across all columns

• • Certified Welding: AWS D1.1 qualified welders using approved WPS/PQR

• • Trial Assembly: Optional pre-assembly to verify fit before shipment

• • Surface Treatment: Shot blasting, priming, painting or hot-dip galvanizing

• • Marking & Packing: Clear identification and export-ready packaging

4. Connection Design & Interface Engineering

We provide complete connection solutions to simplify field erection:

• • Base plates with anchor bolt holes, stiffeners and grout holes

• • Cap plates for beam-to-column connections

• • Gusset plates for bracing and diagonal members

• • Bolted splices using high-strength bolts (A325/A490)

• • Welded splices with full penetration or fillet welds as required

• • Shear tabs, end plates and moment connections custom-detailed to your frame

Our engineers deliver shop drawings, 3D models and connection calculations to ensure compatibility with your primary structure.

5. Corrosion Protection Strategy

• • Hot-dip galvanizing to ASTM A123 for exterior or humid environments

• • Shop primer for temporary protection during transit and storage

• • Epoxy or polyurethane paint systems for architectural finishes

• • Fire-resistant coatings available on request

• • Surface preparation including shot blasting to SSPC-SP6 or SP10

6. Quality Assurance & Traceability

• • Material Traceability: Mill test certificates for all steel

• • Welding Documentation: WPS/PQR, welder certificates and weld maps

• • NDT Inspection: UT, MT or PT on critical joints as specified

• • Dimensional Verification: Length, straightness, hole positions and fit-up

• • Coating Inspection: Thickness and adhesion testing

• • Final Documentation: Inspection reports, as-built drawings and compliance records

7. Applications in Industrial & Commercial Buildings

Our custom tubular columns are widely used in:

• • Industrial plants and manufacturing facilities

• • Warehouses and distribution centres

• • Commercial office buildings and retail centres

• • Airports, stadiums and exhibition halls

• • Heavy-duty platforms and equipment support structures

• • Seismic-resistant building frames
