Structural hollow sections are the foundation of modern steel construction. From industrial sheds and solar structures to oil & gas plants and infrastructure projects, hollow sections provide exceptional strength-to-weight ratio, durability, and design flexibility.

The three most commonly used steel hollow section types are:

Rectangular Hollow Section (RHS)

Square Hollow Section (SHS)

Circular Hollow Section (CHS)

Each profile offers unique structural advantages depending on load type, span, fabrication needs, and environmental conditions.

In this detailed RHS vs SHS vs CHS comparison, we break down strength differences, load capacity performance, and the best applications for each section — helping engineers, contractors, and fabricators choose the right solution.

1. What Are RHS, SHS and CHS? (Clear Structural Overview)

Rectangular Hollow Section (RHS)

RHS features a rectangular profile with different width and height dimensions. This geometry makes it ideal for directional strength applications, especially where bending resistance is critical.

Best known for: Strong bending performance and long-span beams.

Square Hollow Section (SHS)

SHS has equal width and height, providing symmetrical structural behavior across both axes. It performs efficiently in compression and column applications.

Best known for: Balanced axial load-bearing capacity.

Circular Hollow Section (CHS)

CHS has a uniform circular cross-section that distributes stress evenly in all directions. It offers superior torsional resistance and performs exceptionally under dynamic and wind loads.

Best known for: Multi-directional load resistance and torsional strength.

2. RHS vs SHS vs CHS Strength Comparison

When comparing RHS SHS CHS strength, the difference lies in how each section responds to specific structural forces.

RHS Strength

Excellent bending resistance

Strong performance under vertical loads

Higher moment of inertia in one direction

Ideal for beams and horizontal frameworks

RHS is preferred where load direction is predictable and bending is dominant.

SHS Strength

Uniform axial strength

Balanced performance across both axes

Reduced buckling risk in columns

Efficient for vertical load-bearing

SHS is ideal for structural columns and modular frameworks.

CHS Strength

Highest torsional resistance

Even stress distribution

Excellent under wind, vibration, and rotational forces

Strong fatigue resistance

CHS performs best in dynamic environments and multi-axial stress conditions.

3. Hollow Section Load Capacity Comparison

Understanding hollow section load capacity is essential for structural safety and cost optimization.

RHS Load Capacity

Strong in one primary direction

High bending and buckling resistance

Suitable for long spans

Easy bolted and welded connections (flat surfaces)

SHS Load Capacity

Strong compression capacity

Symmetry improves column stability

Reliable axial load performance

Efficient structural design

CHS Load Capacity

Strong in all directions

Best performance under torsion

Excellent resistance to wind-induced forces

Suitable for cyclic and dynamic loading

Quick Summary:

RHS dominates in bending

SHS excels in compression

CHS leads in torsional and multi-directional loads
