Galvanized Steel Coil & Sheet & Strip

Magnesium Aluminum Zinc Alloy Coated Coil

    Thickness: 0.27mm-2.0mm


    Width: 1000mm-1250mm 


    Coating weight:  ZM30-ZM275

Product description:

Magnesium Aluminum Zinc alloy coated sheet has excellent corrosion resistance, scratch resistance and good forming ability. 

It can be applied in wide range of fields such as road/civil engineering, farming, construction, housing and others.

Shanghai Metal Corporation has succeeded to establish business relationship  with clients in Europe and Southeast Asia. 

It is chosen to be the newest coated steel material which is widely used in steel structure engineering, power engineering, solar power engineering, etc.

It is available in a very wide range of steel grades: steels for cold forming and deep drawing applications, structural steels and High Strength Low Alloy steels.

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



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



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
