Structural Hollow Sections are high-strength steel profiles with hollow cross-sections designed for load-bearing structures, frames and fabricated steel components. They provide an excellent strength-to-weight ratio, clean appearance, good torsional resistance and efficient material utilization.

ZSJH Steel supplies Square Hollow Sections (SHS), Rectangular Hollow Sections (RHS) and Circular Hollow Sections (CHS) in different dimensions, wall thicknesses, steel grades and surface finishes. Cutting, drilling, welding, galvanizing, painting and other customized fabrication services are available according to project drawings.

Our structural hollow sections are widely used in industrial buildings, warehouses, bridges, equipment frames, support systems, renewable energy structures and general steel fabrication projects.

Main Product Types

Square Hollow Section – SHS

Square hollow sections offer uniform strength in both directions and are commonly used for columns, frames, supports, trusses and architectural structures.

Rectangular Hollow Section – RHS

Rectangular hollow sections provide high bending resistance and are suitable for beams, wall frames, equipment supports, platforms and structural frameworks.

Circular Hollow Section – CHS

Circular hollow sections provide excellent torsional resistance and smooth load distribution. They are widely used for columns, space frames, pipe trusses, towers and exposed architectural structures.

Typical Specifications

Key Product Advantages

High Structural Strength

The closed-section design provides excellent resistance to bending, compression and torsion, making hollow sections suitable for demanding structural applications.

Excellent Strength-to-Weight Ratio

Structural hollow sections reduce unnecessary steel weight while maintaining reliable load-bearing performance, helping optimize material and transportation costs.

Clean Architectural Appearance

SHS, RHS and CHS profiles have smooth surfaces and simple lines, making them suitable for both concealed structural frames and visible architectural applications.

Flexible Customization

Dimensions, wall thicknesses, lengths, steel grades and surface treatments can be customized according to engineering drawings and project requirements.

Easy Fabrication

The sections can be cut, drilled, welded, punched and assembled into columns, beams, trusses, platforms and other fabricated steel components.

Reliable Corrosion Protection

Hot-dip galvanizing, zinc-rich primer, protective painting and powder coating are available for indoor, outdoor and corrosive environments.

Applications

Structural hollow sections are commonly used in:

• Industrial steel buildings

• Steel structure warehouses

• Factory workshops

• Building columns and beams

• Roof trusses and space frames

• Equipment support frames

• Steel platforms and walkways

• Bridges and pedestrian structures

Manufacturing and Quality Control

Our quality control process covers raw material inspection, production monitoring and final product inspection.

Raw Material Inspection

Steel plates and coils are checked for grade, thickness, surface condition and material certificates before production.

Production Inspection

Dimensions, wall thickness, straightness, corner radius, weld seam quality and surface condition are monitored during manufacturing.

Final Inspection

Finished products are inspected for cross-sectional dimensions, length, straightness, appearance, packaging and order quantity before shipment.

Material Test Certificates can be provided with the order. Third-party inspections by SGS, BV or TÜV can also be arranged when required.

Customized Fabrication Services

In addition to supplying standard hollow sections, we can provide:

• Fixed-length cutting

• Angle cutting and mitre cutting

• CNC drilling

• Hole punching

• Slot processing

• Plate and flange welding

• Connection component fabrication

• Structural frame assembly

Customers can send drawings in DWG, DXF, PDF, STEP or other commonly used formats for technical evaluation and quotation.

FAQ

1. What is a Structural Hollow Section?

A Structural Hollow Section is a steel profile with a hollow square, rectangular or circular cross-section. It is used for load-bearing frames, columns, beams, trusses and fabricated structural components.

2. What is the difference between SHS, RHS and CHS?

SHS refers to Square Hollow Section, RHS refers to Rectangular Hollow Section and CHS refers to Circular Hollow Section. The appropriate type depends on the load direction, connection design and architectural requirements.

3. Can you customize the dimensions and wall thickness?

Yes. Dimensions, wall thickness, length, steel grade and surface treatment can be customized according to the project drawings and required quantities.

4. Can you provide galvanized hollow sections?

Yes. Hot-dip galvanized SHS, RHS and CHS products are available for outdoor, humid and corrosive environments.

5. Can you cut and drill the hollow sections?

Yes. We provide fixed-length cutting, angle cutting, drilling, punching, slotting, welding and component assembly services.
