Cold Rolled Hollow Sections
Cold rolled hollow sections are precision-engineered steel profiles with a hollow cross-section, produced through advanced cold forming processes without the use of heat. These sections are highly valued across diverse industries due to their superior dimensional accuracy, smooth surface finish, and enhanced mechanical properties. Available in a wide range of shapes including square, rectangular, circular, and elliptical, cold rolled hollow sections offer an optimal balance between strength, weight, and design flexibility, making them indispensable in modern construction, manufacturing, and engineering applications.
Manufacturing Process and Material Advantages
The production of cold rolled steel profiles begins with cold rolling steel coils, gradually shaping them into the desired hollow profiles under high pressure. This process significantly improves the material’s yield strength and tensile strength compared to hot-rolled equivalents. The cold forming method ensures tight dimensional tolerances, consistent wall thickness, and a smooth, clean surface finish, making these sections ideal for applications where precision, strength, and aesthetics are critical.
Another key advantage of cold rolled RHS / SHS (Rectangular/Square Hollow Sections) is their exceptional strength-to-weight ratio. These profiles provide high load-bearing capacity while remaining lightweight, which reduces material costs and simplifies handling and installation. Engineers and architects frequently choose cold rolled hollow sections for structural frameworks, trusses, support columns, and space frames, especially in architectural projects emphasizing sleek lines and minimalistic designs.

Versatile Applications Across Industries
Beyond construction, Cold formed hollow sections play a critical role in machinery manufacturing, agricultural equipment, transportation vehicles, and furniture production. Their versatility allows them to be cut, drilled, welded, and fabricated into a wide range of components and assemblies. Additionally, the cold rolling process refines the steel’s grain structure, providing improved fatigue resistance and superior performance under dynamic or cyclic loading conditions.
Cold rolled hollow sections are available in an extensive range of sizes, thicknesses, and material grades to suit diverse project requirements. Standard grades such as S235, S275, and S355 offer excellent weldability and formability, while higher-grade materials can be selected for applications requiring superior strength and durability. Surface finish options, including galvanized or painted coatings, further extend the product’s service life by enhancing corrosion resistance, particularly in outdoor or harsh environments.
Sustainability and Environmental Impact
Sustainability is another key factor driving the growing popularity of cold formed hollow sections. Steel is one of the most recyclable materials worldwide, and using hollow sections allows for material optimization, reducing the overall carbon footprint of a project. Lightweight yet strong, these profiles contribute to energy-efficient construction and minimize the environmental impact across the entire product lifecycle.
Standards, Certifications, and Quality Assurance
Cold rolled hollow sections adhere to international standards such as EN 10219, ASTM A500, and BS EN 10305, ensuring consistent quality, mechanical performance, and safety. Manufacturers implement rigorous quality control measures, including dimensional inspections, mechanical property testing, and non-destructive evaluation, to guarantee the reliability and integrity of each product.
Selecting the right cold rolled hollow section depends on various factors, including load requirements, environmental conditions, design specifications, and cost considerations. Consulting with experienced suppliers and structural engineers ensures that you choose the most suitable profile that aligns with both technical and budgetary needs.
