Before annealing and galvanizing process, the emulsion and the abrasion have to be removed. Firstly, strip is immersed through an alkaline cleaning, an electrolytic cleaning and brushing section. Finally, rinses and dry the strip for ensuring the clean surface.
This process is necessary for achieving the desired mechanical properties by deformation. Maximum elongation is 3% under wet condition. The surface structure and roughness of strip are made by passed through the two work rolls. The SPM EDT (Electro Discharged Texture) work rolls are introduced to work for a high elongation with low force especially for making the products excellent surface. Then the following tension leveller will ensure the optimal strip flatness.
Hot-dip galvanized steel products are now being used in a wide range of automobiles, electrical equipments and other industrial machinery as well as in civil engineering and construction.
Since hot-dip galvanized steel products are characterized in excellent formability, weldability, paintability as well as anti corrosion, they can meet the high quality requirements of the users.
POSCO Coated Steel Thailand (PTCS) will continue to make its best efforts to produce much more superior products.
