Understanding Circular Hollow Sections
Circular Hollow Sections (CHS), commonly known as CHS steel, are tubular steel sections with a hollow, circular cross-section. Their structural efficiency, aesthetic appeal, and versatility make them indispensable in various engineering and architectural applications.
At DC Iron, we supply a comprehensive range of CHS steel components to meet diverse project requirements.
What Are CHS Sections?
CHS sections are a type of Hollow Structural Section (HSS), characterised by their circular cross-sectional shape. Unlike other HSS types—such as Rectangular Hollow Sections (RHS) and Square Hollow Sections (SHS)—CHS sections offer uniform geometry along all axes.
This uniformity provides consistent strength and aesthetic appeal, making them a preferred choice in various structural applications.
Types and Manufacturing of CHS Steel
CHS sections are available in two primary manufacturing types:
Hot-Finished CHS: Produced by heating steel to high temperatures and forming it into the desired shape. This process enhances the material's mechanical properties, making hot-finished CHS suitable for structural applications requiring high strength and toughness.
Cold-Formed CHS: Manufactured at room temperature, cold-formed CHS sections are shaped without the application of heat. While this method is cost-effective and allows for precise dimensions, cold-formed CHS may have different mechanical properties compared to hot-finished sections.
Standard Specifications and Sizes
In Europe, CHS sections are standardised under EN 10210-2 for hot-finished sections and EN 10219-2 for cold-formed sections. These standards specify dimensions, tolerances, and sectional properties to ensure uniformity and reliability across applications.
At DC Iron, we offer a wide range of circular hollow section sizes to accommodate various project specifications. Our inventory includes diameters ranging from 21.3 mm to 219.1 mm, with wall thicknesses varying to meet specific structural requirements. Whether you're undertaking a residential project or a large-scale industrial development, our selection ensures the right fit for your needs.
Advantages of CHS Steel
Structural Efficiency: The uniform geometry of CHS sections provides consistent strength along multiple axes, making them ideal for supporting axial loads and resisting bending moments.
Aesthetic Appeal: The smooth, continuous lines of circular hollow sections offer a modern and sleek appearance, enhancing the visual appeal of architectural designs.
Versatility: CHS steel's adaptability allows for its use in a wide range of applications, from structural columns and beams to mechanical components and recreational structures.
Applications of CHS Steel
The versatility of CHS steel components extends across various industries and applications, including:
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.
Mechanical and Automotive Applications: Used in manufacturing components like drive shafts, roll cages, and exhaust systems, contributing to vehicle safety and performance.
Piping and Fluid Transportation: Suitable for transporting fluids and gases in systems such as water treatment plants, oil and gas pipelines, and HVAC systems.
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.
Offshore and Marine Structures: Preferred in offshore structures like oil rigs and marine platforms due to their ability to minimise wave forces and enhance stability in aquatic environments.
