Did you know that galvanization is the process of applying a protective zinc coating to steel or iron to prevent rusting? The most common method in Gi Coil Sheet metal fabrication shops is hot-dip galvanizing. This is the process of submerging metal parts in a bath of molten zinc to protect the metal.

Galvanized Steel Gi Sheet is among the most popular steel types because of its extended durability, having the strength and formability of steel plus the corrosion protection of the zinc-iron coating. The zinc protects the base metal by acting as a barrier to corrosive elements, and the sacrificial nature of the coating results in a long-lasting and high-quality steel product.

WHAT IS ZINC ALUMINUM-MAGNESIUM COATED STEEL

This Zinc Aluminum Magnesium Steel Coils which is also called ZAM coated steel is one newly developed with coating layers of 100-450g +/-10g which owns very strong corrosion-resistant ability. And zinc aluminum-magnesium coated steel is a new type of corrosion-resistant coated steel sheet consisting mainly of zinc, about 11% aluminum, 3% magnesium and trace amounts of silicon. Our Zam Coils adds Al, Mg, Si to the conventional Zn plating, and the these added chemicals elements improve the corrosion resistance. That is, in addition to the previous Al addition, added to the zinc aluminum magnesium coil products have the significant effect on the Mg, in addition, to meet the addition of Si, so that rust effect can be improved. Si improves the corrosion resistance of the coating layer containing Al while further improving the corrosion effect by the combination with Mg. This Zin Aluminium Magnesium steel feathers superior corrosion-resistance on the surface, bend processed parts, ammonia environment, cut edge, drawing-processed parts. And it’s HS code is 72109000.

Zn Al Mg Alloy Coils Advantages

 Excellent anti-rust performance! The rust-proof performance of the flat part is no need to speak.

With a history that stretches back over 150 years, there are innumerable examples of galvanised steel in use in many environments, which prove its performance.

Galvanized Tube is all around us, in a whole variety of industries including road, rail, energy plants, oil and gas, agriculture, water and waste and sports and leisure. It can play an important role for buildings, bridges, facades, signal gantries, gates, balconies and even sculptures. Wherever there is a risk for corrosion of steel, galvanising should be used.

An average coating thickness of 85 microns, the same thickness as a sheet of A4 paper, can protect a steel structure for the better part of 100 years. One of the inherent benefits of hot dip galvanizing is that when clean steel that is greater than 6mm thick is submerged into molten zinc, it will develop a minimum mean coating of 85 microns.
