Blechstreifen

Blechstreifen are narrow strips of metal that have been rolled or stamped from a sheet or plate. The term is commonly used in German-speaking countries and refers to a variety of thin, flat metal parts that can be made from steel, aluminium, brass, or other alloys. The dimensions of Blechstreifen vary widely: width ranges from a few millimetres up to several centimetres, while thickness can be as low as a tenth of a millimetre to several millimetres. Production processes include cold rolling, hot rolling, stamping and laser cutting, depending on the required precision and material properties.

Applications of Blechstreifen are diverse. In the automotive industry they serve as reinforcement elements, components in exhaust systems, and as parts of chassis and bumper structures. In construction, they are used for roofing, cladding, guttering, and structural reinforcement of concrete. The electrical industry employs metal strips for grounding, shielding, and as parts of printed circuit boards. Blechstreifen are also used in consumer goods for shelving, furniture, and decorative purposes. Their versatility derives from the ease of shaping, the high strength-to-weight ratio of many alloys, and the availability of manufacturing techniques that allow for precise control of dimensions and surface finishes.

Quality control for Blechstreifen involves dimensional verification, defect inspection, and chemical composition analysis. Standards such as DIN EN 10218 for hot rolled steel and DIN ISO 3635 for aluminium ensure consistency and predictability of mechanical properties. Because of their widespread use, Blechstreifen are often supplied in rolls or bundled units, allowing for efficient handling in factories and warehouses.
