What is a ceiling galvanized sheet?
Roof galvanized sheet refers to steel that has gone through the galvanization process in the form of a flat plate in order to prevent corrosion. The galvanization process by the steel sheet that is subjected to a chemical process increases the resistance to corrosion. This process also makes the steel much stronger and more reliable in terms of stability.
The general steps of producing galvanized ceiling sheets
Welding process
A continuous sheet is formed by welding the ends of cut steel sheets.
The process of straightening
A high-performance tensile surface former is used to smooth the steel sheet.
The process of cleaning
The steel sheet is cleaned in an alkaline bath and washed for primary degreasing to reduce surface oxides and provide proper adhesion to the coating.
The continuous cooking process
This step includes reducing the oxidized film on the surface of the steel sheet by continuously passing it through the reduction furnace.
Galvanized process
The sheet is placed in a reducing atmosphere and directly immersed in a bath of molten zinc. The steel sheet is rolled around a roller, which is inside the tub of coating impregnated with zinc element, and by pulling it, it is vertically removed from the bath. Excess molten zinc is removed using high pressure air to obtain a precisely controllable coating thickness.
The chemical treatment process
The coated zinc sheet is subjected to different chemical treatments according to the intended application. These operations include phosphate treatment for excellent colorability and special chromate removal operations for corrosion resistance.
