After degreasing treatment of steel strip made from cold rolling machine line ,steel strip is sent to continuous hot zinc galvanized machine line for the following processing:
1. annealed in annealing furnace.
2. hot dipped and zinc galvanized in molten zinc .
3. passivation or polishing
4. elongation and leveling
All the processing above constitute necessary manufacturing steps of hot zinc galvanized steel plate.
