Composition of Coating

Mg-Al-Zn coated sheet is a highly corrosion-resistant hot-dipped coating steel sheet that has a coated layer of Zinc, 13% Aluminum, 3% Magnesium, and Silicon element.

Corrosion Mechanism

Al & Mg form a fine, tight protective film

Mechanism of corrosion resistance on flat surface

Mechanism of corrosion resistance on cut edge

Manufacturing Process

Chemical Composition

Steels for cold forming and deep drawing applications

Structural steels

Application

1) Construction: structural or non-structural profiles, roofing & cladding, decking, cable trays, expanded metal, gratings, composite flooring, concrete moulds

2) Road and railway infrastructure: safety barriers, protection equipment, sound insulation wall panels, walls providing protection against hail

3) Agriculture and farming: barns, greenhouse structures, agricultural equipment

4) Solar energy generation: structures for photovoltaic plants

5) Tubular applications: structural tubes for scaffolding, road signals, poles

Advantage

1) Excellent corrosion resistance on both surface and edge. 8-10 times of anticorrosion than GI

2) Excellent forming properties

3) Better welding ability than galvanized sheet and galvalume sheet

4) Less metallic coating with high anti-corrosion

5) Competitive price with high quality
