Hot dip (or hot) galvanizing is the technology to dip the pretreated original plate of carbon steel into meltedliquefied zinc to obtain a protective zinc coating.

Material properties and surface qualities are adjusted by the skin pass mill in combination with the tension leveler. Closest elongation tolerances and best surface quality are achieved by using the high-pressure cleaning device, which limits unscheduled work roll and back-up roll changes to the minimum necessary. The automatic coater control in the post-treatment section adjusts the layer thickness quickly and accurately, including a quick open and close function for weld seam passing. Exact width trimming by the turret-type side trimmer completes the continuous galvanizing line: a processing line with patented innovations and high-quality technology in each line section.

We provide two kinds of technologiesof hot dip galvanizing (galvalume) lines: "United States Steel Corp"and independently researched and developed “JJRS-Sendzimir” .
