ZSJH Steel manufactures custom fabricated box steel columns for industrial, commercial, infrastructure, and prefabricated steel building projects. Components can be produced according to customer drawings, structural calculations, steel grades, connection details, welding requirements, and surface protection specifications.

We support both standard and project-specific fabrication, allowing customers to source steel columns that are ready for assembly and installation on site.

Technical Specifications

Main Advantages

High Structural Strength

The closed box-shaped section provides excellent overall rigidity and allows the column to withstand significant vertical and horizontal loads.

Strong Torsional Resistance

Compared with many open steel sections, box columns provide better torsional performance and structural stability.

Flexible Customization

Column width, height, wall thickness, length, stiffeners, base plates, connection plates, bolt holes, and welding details can all be customized.

Reliable Fabrication Quality

Controlled cutting, fitting, welding, drilling, grinding, and inspection processes help ensure dimensional accuracy and consistent fabrication quality.

Suitable for Heavy Structures

Box columns are particularly suitable for large industrial buildings, multi-level steel structures, heavy-duty workshops, and other projects requiring strong structural support.

Surface Treatment Options

Different surface protection systems are available according to the installation environment:

Shot Blasting
Removes rust, mill scale, and surface contaminants before coating.

Primer Painting
Provides basic corrosion protection for structural steel components.

Multi-Layer Painting System
Suitable for projects requiring enhanced corrosion resistance.

Hot-Dip Galvanizing
Available for projects requiring long-term outdoor corrosion protection.
