We apply thermal spraying and overlay welding for rolls, chocks and equipments related to them in rolling lines.
The thermal spraying and overlay welding are also applied to the roll-related equipments and guide rolls in the leveler line.
By applying our original blend material using PTA overlay welding for sleeves and bushes in the galvanized steel sheet
manufacturing line, we engage in machine parts that require corrosion resistance and wear resistance to Zn.
In addition, we are able to manufacture bearings that operate in a plating bath with a longer life than conventional bearings.
