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.
This protection occurs in three different ways:
The zinc coating, when intact, prevents corrosive substances from reaching the

underlying steel or iron.
It acts as a sacrificial anode, which is the main component of a galvanic

cathodic protection (CP) system used to protect buried or submerged metal from corrosion.

This means that if the coating is scratched, the exposed steel or iron will be protected by

the remaining zinc.
The zinc protects its base metal by corroding before iron.
Galvanizing, or galvanization, is a manufacturing process where a coating of zinc is

applied to steel or iron to offer protection and prevent rusting. There are several

galvanizing processes available, but the most commonly offered and used method is called

hot-dip galvanizing.
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.
This versatility makes it applicable to a variety of projects and industries, including

agriculture, solar, automotive, construction, and so on. Below, we aim to provide a

comprehensive description of how galvanized steel is processed, different galvanization

methods, its benefits, and how it is used in these various industries.
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
1. Excellent anti-rust performance! The rust-proof performance of the flat part is no

need to speak.
2. The rust resistance of the end face is also excellent.
3. Moreover, alkali resistance is also excellent. This zinc aluminum magnesium steel

coil in comparison with hot-dip galvanized steel and hot-dip galvanized 5% aluminum alloy

steel, can achieve the same corrosion resistance but use less plating layers. In addition,

because of its excellent resistance to red rust, it can be used to be instead of stainless

steel or aluminum plate.
4. Excellent processing property performance! Bending portion, the stretching portion

is also hard to rust, surface processing is not rare injuries, very beautiful.
5. Weldability, paint is also very good.
6. Withstand the rigors of processing with the plating adhesion. In addition, the

coating hardness is high, with excellent resistance to damage.
7. Super VA’s new material can greatly reduce costs and shorten delivery time due to

the no need for post-plating.
8. May also be a substitute for stainless steel and aluminum.
9. It is resistance to severe conditions of the processing of adhering. In addition to

high hardness coating, with excellent resistance to damage.
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.
