Hollow and thin-walled profiles (Structural hollow sections)
Hollow profiles, also known as structural hollow sections, are thin-walled rolled profiles with closed cross-section – square, rectangular or circular. Thanks to optimal strength-to-weight ratio, they are ideal for modern welded structures where material savings are important while maintaining high load capacity. They are manufactured in two ways: by hot rolling (hot finished) directly from steel ingots, or by cold forming from steel strips, which are bent into the desired shape and longitudinally welded. Square and rectangular profiles have excellent compression properties and are used as columns and reinforcements, circular hollow profiles find application in structures with high aesthetic requirements. We supply profiles in grades S235 to S355 according to European standards, in various sizes and wall thicknesses, with custom cutting available.
