hot-dip galvanized steel DX53D
The hot-dip galvanized steel DX53D in accordance with standard 10346 is a modern material that has been specially developed for demanding cold forming processes. With the material number 1.0951 (formerly 1.0355), this steel belongs to the soft steels and is classified as a deep-drawing grade. The integrated hot-dip galvanizing process applies a durable zinc coating that provides reliable corrosion protection and makes the steel resistant even under adverse environmental conditions. In addition, the wide range of coating variants – +Z, +ZF, +ZA, +ZM, +AZ and +AS – ensure individual adaptation to specific requirements in different manufacturing processes.
