Engineered Steel Profiles for Modern Structures

Structural Hollow Sections combine high load-bearing capacity with efficient material usage. Their closed-profile design provides stable mechanical performance, good torsional resistance and a clean structural appearance.

ZSJH Steel supplies hollow steel profiles for contractors, fabricators, steel building companies and industrial equipment manufacturers. Our products can be supplied as standard-length steel sections or processed into project-ready components according to customer drawings.

Available profiles include square, rectangular and circular hollow sections in carbon steel, galvanized steel and coated steel options.

Choose the Right Hollow Section

Product Supply Options

Carbon Steel Hollow Sections

Raw black steel sections are suitable for general fabrication, indoor structures and projects requiring further welding, cutting or coating.

Galvanized Hollow Sections

Hot-dip galvanized sections provide improved corrosion resistance for outdoor buildings, agricultural structures, solar supports and humid environments.

Painted Hollow Sections

Primer, epoxy coating, polyurethane coating and other protective paint systems can be supplied according to environmental conditions.

Fabricated Hollow Section Components

Sections can be cut, drilled, welded and assembled with connection plates, base plates, stiffeners and other components before shipment.

General Product Parameters

Why Structural Hollow Sections?

Efficient Load-Bearing Performance

The closed cross-section distributes stress effectively and provides reliable performance under compression, bending and torsional loads.

Lower Structural Weight

Compared with some solid or open steel profiles, hollow sections can reduce material weight while maintaining the required structural capacity.

Simplified Connections

Flat surfaces on SHS and RHS products make it easier to install connection plates, brackets, cladding supports and secondary steel components.

Better Visual Appearance

Clean lines and smooth external surfaces make hollow sections suitable for exposed structures, commercial buildings and architectural projects.

Flexible Corrosion Protection

Different coating systems can be selected according to indoor, outdoor, coastal, humid or industrial operating conditions.

The service environment should be considered when selecting a surface treatment.

FAQ

Can structural hollow sections be used as building columns?

Yes. SHS, RHS and CHS profiles can be used for columns when their dimensions, material grade and wall thickness are selected according to the structural design.

Which profile is best for a steel frame?

SHS is commonly selected for columns and balanced loading, RHS for beams and directional bending, and CHS for torsional or exposed structural applications.

Can you manufacture products according to our drawings?

Yes. We can review drawings and provide cutting, drilling, welding, surface treatment and component assembly services.

Are galvanized products suitable for welding?

Galvanized hollow sections can be welded using appropriate procedures. However, many projects complete the welding before hot-dip galvanizing to achieve more consistent corrosion protection.

Can you supply different lengths in one order?

Yes. Multiple fixed lengths can be produced and marked according to the approved cutting list.

How do you control dimensional accuracy?

We inspect external dimensions, wall thickness, length, straightness, corner shape and hole positions according to the agreed requirements.
