Technical consulting and development support Your benefits: increased product quality and profitability Applications engineering Markets and industries are constantly changing and with that, the demands for the applied materials. Our proximity to the procurement and sales markets enable us to react to changing demands and utilize the potential of latest technological developments to the maximum. Improved profitability by means of material savings Steel grades with an increased yield strength lead to an application with reduced wall thickness. Thus, material consumption goes down, and at the same time your overall costs. Utilizing weight-saving potentials by using high strength steels Applications, for which weight reduction is the vital key requirement, require the use of technologically advanced high strength steels. This enables saving weight by up to 39 %. Increased product reliability by means of property-optimized materials Applications, which are exposed to extreme conditions such as very low temperatures or aggressive media, make the highest demands on the material. The selection of the appropriate material is decisive for the quality of your product. Fulfillment of individual high performance requirements by means of precisely designed products In close collaboration with leading technological steel tube manufacturers, we support you in the development of individual steel tube products for specific material requirements. 5
