1219mm Width Galvanized Sheet Metal, Galvanized Steel Flat Sheet EL20
Introduction of galvanised steel sheet:
Galvanized steel plate is to prevent corrosion on the surface of the steel plate to prolong its service life, coated with a layer of metal zinc on the surface of the steel plate, the zinc coated steel plate is called galvanized plate.

Advantage of galvanised steel sheet:
| 1 | Flame retardant | self-extinguish, even without any flame retardant, can reach UL standard 94V-0 level |
| 2 | Easy to process | it has the characteristics of high temperature fluidity and high thermal decomposition temperature, and can be used in a variety of processing methods: injection molding, extrusion molding, molding and melt spinning, etc |
| 3 | Peel resistance | it has the characteristics of high temperature fluidity and high thermal decomposition temperature, and can be used in a variety of processing methods: injection molding, extrusion molding, molding and melt spinning, etc |

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.
