We develop weight-optimised, heavy-duty steel sections for trailer and semi-trailer applications. These sections combine low weight with high load-bearing capacity and are suitable for demanding structural components in the commercial vehicle sector. Complex cross-sections are manufactured to exact dimensions in various material grades – including stainless steel. By optimising the strip thickness to withstand the loads, weight and material usage can be efficiently reduced. Precise perforations, notches and mitres are integrated directly into the production process, eliminating the need for additional machining steps. Flexible production and logistics planning also enables reliable just-in-time deliveries.
