process for the production of an outer corrosion protection for labour stahlprofiles and its application

摘要

the invention concerns a process for the production of an outer corrosion protection inflation profile from a high-strength and tough steel with the steps of manufacture an initial section, heat treatment, descaling and applying a zinc.a method to indicate with the simpler and cheaper way an outer corrosion protection aufweisendes steel can be produced, it is proposed that the coating part of the heat is.
