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 requirementsby 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.

Technical consulting and development support

Your benefits: increased product quality and profitability
