Product Description
What is Z-A-M ?
Znic-Aluminum-Magnesium Alloy Stell Coil
Zinc aluminum-magnesium coated steel is a new type of corrosion-resistant coated steel sheet consisting mainly of zinc, about 6% aluminum, 3% magnesium and trace amounts of silicon.
Z-A-M is a highly corrosion-resistant hot-dip Zinc-Aluminum-Magnesium alloy coated steel sheet. Due to the effects of magnesium and aluminum, Z-A-M has excellent corrosion resistance, scratch resistance and formability.
PRODUCT ADVANTAGES
Z-A-M is the lastest material which can replace the galvanized steel and galvalumed steel.
Superior corrosion resistance-Long product life
Substitute for post hot-dip galvanizing
Light coating weight yet high corrosion resistance
Reduction in both coating and transportation costs
LCC(Life Cycle Cost) Reduced repair cost
Reduced manufacturing cost
Eco-friendliness through process saving
Due to the effects of magnesium and aluminum, Z-A-M has excellent corrosion resistance, scratch resistance as well as formability, and can be applies in a wide range of fields.
Superior corrosion resistance-1
In terms of corrosion resistance, Z-A-M™ is 10 to 20 times better than hot-dip zinc-coated steel sheets*1 and 5 to 8 times better than hot-dip zinc-5%aluminum alloy coated steel sheets*2.(Estimated by salt spray test.)
Superior corrosion resistance-2
One of the biggest features:Self-Healing.
(Z-A-M:Cut edges covered with thin zinc based protective film containing Mg.)
Excellent corrosion resistance is achieved on cut edge of Z-A-M with a fne zinc-based protective film that contains Al and Mg leaching from the coating layer.
| 1. Am Zinc Aluminum Magnesium Coil simple description
Zn-Al-Mg is a new type of highly corrosion-resistant coated steel sheet with a coating composition consisting of zinc as the main substrate in combination with aluminum (about 11%), magnesium (about 3%) and a trace amount of silicon.Adding Al, Mg, and Si to it, the composite effect of these added elements improves corrosion resistance.
2.Mechanism of corrosion: Al and Mg in the coating layer of Z-A-M combine to form a fine, tightly adhered zinc-based protective film on its coating surface as time passes. This protective film suppresses corrosion of the Z-A-M coating.Cut edges covered with thin zinc based protective film containing Mg. |
