Compared with many open steel profiles, hollow sections provide an excellent strength-to-weight ratio, good torsional resistance and clean structural appearance. They are widely used as columns, frames, supports, trusses, equipment structures and secondary structural members.

We provide Structural Hollow Sections for both standard and customized projects, with optional cutting, drilling, welding, punching, galvanizing, painting and further fabrication services.

Structural Hollow Section Types

Square Hollow Section – SHS

Square Hollow Sections feature equal width and height dimensions and provide excellent structural stability.

Typical applications include:

• Steel columns

• Building frames

• Support structures

• Equipment frames

• Platforms

• Railings

• Steel trusses

• Industrial structures

Rectangular Hollow Section – RHS

Rectangular Hollow Sections provide excellent bending resistance and design flexibility, making them suitable for structural beams and frames.

Typical applications include:

• Steel beams

• Roof structures

• Wall frames

• Warehouse structures

• Industrial platforms

• Equipment supports

• Commercial steel buildings

Circular Hollow Section – CHS

Circular Hollow Sections provide uniform strength in all directions and are widely used where torsional performance and architectural appearance are important.

Typical applications include:

• Structural columns

• Space frames

• Canopies

• Towers

• Bridge structures

• Architectural structures

• Infrastructure projects

Technical Specifications

1. High Strength-to-Weight Ratio

The hollow cross-section provides excellent structural performance while helping reduce unnecessary steel weight.

This makes Structural Hollow Sections suitable for both load-bearing structures and lightweight structural systems.

2. Excellent Load-Bearing Performance

SHS, RHS and CHS sections provide good bending, compression and torsional performance for demanding structural applications.

They are widely used as:

• Columns

• Beams

• Bracing members

• Trusses

• Frames

• Equipment supports

3. Excellent Structural Stability

The closed hollow profile helps improve structural rigidity and provides stable mechanical performance under different loading conditions.

4. Easy Welding and Fabrication

Structural Hollow Sections can be processed using common steel fabrication methods including:

• Cutting

• Welding

• Drilling

• Punching

• Bending

• End-plate welding

• Connection plate fabrication

This makes them suitable for customized structural steel projects.

5. Flexible Sizes and Thicknesses

Different cross-sectional dimensions and wall thicknesses can be supplied according to engineering design requirements.

Both standard and custom sizes are available.

6. Clean Architectural Appearance

Compared with many open-section steel profiles, hollow sections provide smooth surfaces and a simple, modern structural appearance.

They can therefore be used for both structural and exposed architectural applications.

7. Multiple Surface Treatments

Depending on the service environment, Structural Hollow Sections can be supplied with different surface protection systems.

Available options include:

• Black steel

• Oil coated

• Primer painted

• Hot-dip galvanized

• Custom paint system

• Powder coated

8. Cost-Effective Structural Solution

Optimized cross-sections can provide strong structural performance while reducing material consumption and fabrication complexity for suitable applications.
