Al-Zn Alloy Plated Steel Plate GL
Introduction to Al-Zn alloy plated steel plate
The aluminum-zinc alloy structure of Al-Zn alloy plated steel plate is formed by curing 55% aluminum, 43.4% zinc and 1.6% silicon at a high temperature of 600℃. The whole structure is a compact quaternary crystal formed by aluminum-iron-silicon-zinc, thus forming a layer of effective barrier capable of preventing corrosion factors from penetrating.
