RHS vs SHS vs CHS: Strength, Load Capacity & Best Applications Compared
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...
