Hohlquerschnitte

Hohlquerschnitte, often translated as hollow sections or hollow structural sections (HSS), are structural elements with a hollow cross-section. They are typically manufactured from steel, aluminum, or other metals. The most common shapes are square, rectangular, and circular. These sections are known for their high strength-to-weight ratio and efficiency in resisting bending and torsional loads. Their closed shape provides excellent torsional rigidity compared to open sections. Hohlquerschnitte are widely used in construction, particularly for structural frameworks, columns, beams, and bridge components. They are also found in mechanical engineering for frames, machine bases, and vehicle chassis. The manufacturing process usually involves welding steel plates or extruding aluminum. Advantages of using Hohlquerschnitte include good aesthetics, ease of connection, and resistance to buckling. Maintenance is also simplified as internal corrosion is less of a concern than in open sections. Their geometric properties make them efficient for load-bearing applications where both axial and bending forces are present.
