Galvanized steel sheet

Galvanized steel sheet is also known as galvanized steel plate. This is a line of steel sheets that are cut and discharged directly from galvanized coils.
Let’s learn more about this product with Tiger Steel!

The production process of galvanized steel sheet

The process below is derived from Hoa Phat’s technology line.
Hoa Phat galvanized steel sheet used to produce galvanized steel sheet is manufactured according to the following steps:
  • Step 1: Unroll the roll. The corrugated iron rolls are put into the machine to discharge the coil into strips, and long steel tapes.
  • Step 2: Clean the steel tape
  • Step 3: Put into an oxygen-free annealing furnace to heat again
  • Step 4: Dip through the plating bath
  • Step 5: Dry and cool the steel strip
  • Step 6: Check and evaluate the coating thickness
  • Step 7: Rolling with a rolling mill to make the steel strip after plating smooth
  • Step 8: The steel strip is chemically coated, dried, and further coated with electrostatic oil to protect the surface.
  • Step 9: Collect the roll

Please see details of equipment, machinery, and production stages in the picture below.
