Metals – The main materials for Brose systems

Our door, window regulator and closure systems impress our customers with their precision, functionality and durability. We use only the best metals, metal components and assemblies in order to meet customers' expectations. In addition to strip steel and aluminum coils, we use prefabricated parts in our deep-drawing, stamping, die casting, welding and cold forming processes. High-strength and ultra-light steels in our front seats help us to set benchmarks for lightweight design.
