Hollow Structural Sections (HSS) are versatile components widely applied in industrial buildings, construction projects, infrastructure and decorative scenarios — from load-bearing frames to facade details.
The Square Hollow Structural Section (HSS) is a modern, cold-formed steel tube renowned for its exceptional structural efficiency and clean architectural lines. With equal dimensions on all sides, it offers uniform strength and stiffness in all directions, making it the ideal choice for columns, space frames, and exposed structural elements where performance and aesthetics are equally important.
CHS Circular Steel Hollow Section
The Circular Hollow Section (CHS) is a versatile and efficient structural tube characterized by its continuous circular cross-section. This shape provides uniform strength in all directions, offering exceptional resistance to torsion and buckling. It is an ideal choice for applications ranging from high-performance structural columns and space frames to fluid-carrying members and architectural features, where its inherent symmetry and smooth profile deliver both engineering and aesthetic benefits.
Our Circular Hollow Sections are manufactured to international standards including ASTM A500/A1085, EN 10219 (cold-formed), and EN 10210 (hot-finished), ensuring consistent quality and performance for global projects. Available in carbon steel grades such as S235JR, S355JR, and ASTM A500 Gr. B/C, they offer a superior strength-to-weight ratio that enables lighter, more material-efficient designs.
The circular geometry is inherently efficient. It provides:
Uniform Strength & Stiffness: Equal load-bearing capacity in every radial direction, perfect for columns and compressive members.
High Torsional Resistance: The closed shape offers the best possible resistance to twisting forces.
Excellent Fatigue Performance: The smooth, continuous surface minimizes stress concentrations.
Optimal Fluid Dynamics: Ideal for structural members that also serve as conduits, pipes, or in fluid-exposed environments.
Key Advantages:
Structural Efficiency: Maximizes load capacity while minimizing weight and material usage.
Design Flexibility: Suitable for both exposed architectural elements and hidden structural components.
Fabrication Friendly: Easy to bend, roll, and form into arches and curves for complex geometries.
Aesthetic Appeal: Offers a clean, modern, and continuous visual line.
Typical Applications:
Structural Systems: Building columns, arched roofs, truss chords, offshore platform braces.
Mechanical & Fluid Systems: Machinery frames, hydraulic cylinder housings, conveyor rollers, process piping supports.
Architectural & Infrastructure: Handrails, light poles, signage posts, sculptural installations, pedestrian bridges.
Industrial: Storage rack uprights, guardrail systems, agricultural equipment frames.
