Ppgi(Prepainted Galvanized Steel) Zn-Al-Mg sheet coil aluminum-Mg plated steel sheet for roof panels – Lu

Introduction

Zn-Al-Mg sheet/coil is a new type of high corrosion resistance coated steel sheet. Its galvanized layer is mainly composed of zinc, which is composed of zinc plus 11% aluminum, 3% magnesium and a trace amount of silicon. At present, the steel plate can be produced The thickness range is 0.27mm—9.00mm, and the production width range is: 580mm—1524mm.

Due to the compound effect of these additional elements, the corrosion inhibition effect is further improved. In addition, it has excellent processing performance under severe conditions (drawing, stamping, bending, paint welding, etc.), the coating has high hardness and damage resistance. Compared with ordinary galvanized and aluminum-zinc-plated products, the amount of plating is less but it can achieve better corrosion resistance. Due to this corrosion resistance, it can be used instead of stainless steel or aluminum in some fields. The anti-corrosion and self-healing effect of the cut end face is a major feature of the product. etc.
