Prepainted Galvanized Steel Sheet HRB70-80 0.38mm Thickness

0.38mm Thickness PrePainted Galvanized Steel Sheet, GI Steel Sheet HRB70-80

Introduction of galvanised steel sheet:

Galvanized steel plate is a steel plate coated with zinc. Galvanizing is an economical and effective method of rust prevention, and about half of the world's zinc production is used in this process.

Specification of galvanised steel sheet:

Advantage of galvanised steel sheet:

1. Strong corrosion resistance, 3 times that of galvanized steel coil.

2.The density of 55% aluminum is smaller than the density of zinc. When the weight is the same and the thickness of the plating layer is the same, the area of the galvalume steel sheet is 3% or larger than that of the galvanized steel sheet.

Surface Treatment Of galvanised steel sheet:

Production procedure of galvanized steel coil

Step 1 Pre-treatment

After the cold-rolled coil arrives in the galvalume workshop, after passing through the uncoiler, through the degreasing section and the reduction furnace, the steel coil is cleaned and its components are reduced to the extent that it can be galvanized.

Step 2 Central section

The most critical technology is this step. After passing through the zinc pot, a layer of zinc layer is plated on the surface of the steel plate. After coming out of the zinc pot, it is cooled and shaped by the cooling tower.

Step 3 Post-processing

The steel plate finally comes to the post-processing stage after various processes. After finishing, straightening and passivation, and finally coiling.
