Cold-Formed Circular Hollow Sections - 457.0x12.0

Cold-formed circular hollow sections (CHS) are strong, tube-shaped steel pipes made by rolling flat steel sheets at room temperature and welding the edges together. Because they are shaped cold without extra heat, the steel undergoes "work hardening," which naturally boosts its strength and hardness. Their smooth, rounded shape gives them excellent resistance to twisting forces and makes them highly efficient at carrying heavy loads from all directions. These versatile pipes are widely used in modern construction for columns, structural frameworks, bridges, and architectural features where both strength and a clean appearance are important.
