Hollow Section

What Is Hollow Section?

Selecting the right hollow section profile depends on the directional forces and load paths of your specific structural application:

• Rectangular Hollow Sections (RHS): Feature unequal sides, making them ideal for uniaxially loaded structural members, such as horizontal beams and floor joists where bending forces act primarily along a single plane.
• Square Hollow Sections (SHS): Provide a balanced geometric profile that offers equal bending resistance across both principal axes, making them the preferred choice for structural columns, space frames, and modular building posts.
• Circular Hollow Sections (CHS): Provide a uniform 360-degree radius of gyration, delivering identical structural resistance to torsional twisting, wind loading, and multi-directional forces.

Product Features

Superior Bending & Torsional Rigidity

The closed-box configuration of hollow sections places material at the outer perimeter of the cross-section, maximizing the moment of inertia and radius of gyration. This allows structural members to resist buckling and twisting under heavy static or dynamic loads.

Steel Weight Optimization & Cost Savings

The high strength-to-weight ratio of hollow sections enables engineering teams to specify lighter wall thicknesses without compromising safety margins. Reducing overall steel tonnage directly lowers raw material acquisition costs, minimizes foundation dead loads, and optimizes ocean transport logistics.

Smooth Surface Quality for Fabrication & Coating

Hollow sections offer scale-free, clean outer surfaces that facilitate automated laser cutting, precise beveling, and clean weld fit-ups. The smooth exterior also provides superior adhesion for protective coatings, including shop primers, architectural powder coats, and heavy-duty Hot-Dip Galvanizing (HDG). 

Application of Hollow Section

Structural Columns and Beams: Ideal for supporting axial loads and resisting bending moments in structures such as bridges, high-rise buildings, and industrial frameworks.

Architectural Aesthetics: Preferred in designs where both form and function are paramount, such as exposed structural elements and artistic installations.

Agricultural Equipment: Employed in the fabrication of machinery frames, irrigation systems, and fencing, ensuring longevity and reliability in demanding farming environments.

Recreational Structures: Used in constructing playground equipment, sports facilities, and park shelters, allowing for creative designs while maintaining structural integrity and safety standards.

FAQ

01.What is a hollow section?

Also called: tubular sections. metal sections of rectangular, square or circular cross-section with a hollow core, formed by seamless welding of roll-formed angle or channel shapes.

02.What is the difference between a hollow section and a tube?

Tubes are measured by their outer diameter and will have a wall thickness, typically measured in inches or fractions. A hollow bar is always round and can look like a pipe or a tube, however, typically the walls are much thicker.
