Epoxy: Epoxy coatings are noted for their remarkable adhesion and corrosion resistance. They are usually utilized as a primer layer beneath other kinds of coatings to improve the overall security on the steel coil.
The pretreatment method, which usually includes cleaning and making use of a conversion coating such as phosphate or chromate, enhances the adhesion with the paint layers.
A: The galvanized steel coil price tag generally is determined by the zinc coating thickness. The thicker the zinc layer, the higher the expense and the higher the corrosion resistance. The galvanized steel used in PPGI includes a thinner zinc coating.

Rinsing the metal strip aids make sure that it's got no chemical residue ahead of making use of primer. Drying Galvanized Steel Roofing Sheet the metal is a necessity to make certain the subsequent layers bond nicely.
The product undergoes this step in order that the steel products is prepared for rewinding, rerolling, and delivery to end customers.
Primer Coating: The primer is applied to the handled base metal to additional boost corrosion resistance and make certain that the topcoat adheres effectively. The primer layer also gives a uniform surface area to the topcoat.
