1. Understand the galvanized coil


Galvanized coils can be divided into hot-rolled galvanized coils and cold-rolled hot-dip galvanized coils. At present, the continuous galvanizing process is mainly used, that is, the rolled steel plate is continuously immersed in a zinc bath to make a galvanized steel plate. Galvanized steel coils are widely used in construction, home appliances, automobiles, containers, transportation, household industries and other fields because of their strong corrosion resistance and good surface quality, which is conducive to deep processing. Especially in steel structure construction, automobile manufacturing, steel structure warehouse manufacturing and other industries.


2. How to choose galvanized coil?


The reason why the surface of the galvanized coil is coated with a layer of zinc is that the steel plate is easily corroded by the oxidation of water and other oxides in the air. In fact, the zinc coating is also to better protect the steel. Galvanized steel coil has two advantages, one is adhesion, and the other is weldability. Due to these two advantages, it is widely used in construction, industry, automotive industry and commerce. Another important feature is corrosion resistance, which works well for the manufacture of appliance housings.


Several key issues should be paid attention to in the selection of steel galvanized coil. Industrial enterprise customers should pay attention to these standards when selecting special industrial raw materials. First of all, we should pay attention to the choice of brands, because the requirements for galvanizing technology are strict, so we have the foundation of big brands. Of course, product quality and technical standards will be more reliable, and there will be better professional standards. The second is to pay attention to the coating quality of the product itself. Coating depends on technology and purity. Therefore, from the surface of the product, quality is a basic and important criterion. The third is to look at the basic materials. Since the quality of the base metal material of the galvanized steel coil is closely related to the quality and durability of the galvanized steel coil, it is necessary to pay attention to this detail when selecting the product.


There are obvious differences in the price of galvanized steel coil sales of different brands, so how to choose is very important, it can bring us good help, so the reliability it can achieve will also have better performance. Of course, by choosing a well-known supplier, you can ensure high production technology and reasonable price. After all, different production levels of galvanized steel strip serve different purposes, especially in terms of performance stability. Therefore, it is necessary to make a reasonable choice according to the actual needs, and the reliability will also get a good performance. These are the links that we should pay more attention to, and the quality will be good.

FAQ of Hot Dipped Galvanized Steel Coil

 

1.Is hot dipped galvanized steel same as galvanized?
Hot-dipped galvanized steel is a type of galvanized steel. Hot dipped galvanizing process is practical, and hot dipped galvanized product is very durable, versatile and highly corrosion-resistant.

 

2.What is the difference between G60 and G90 for galvanized steel?
G90 galvanized steel are coated by the coating weight of zinc 0.90 oz/ft^2 while G60 galvanized steel are 0.60 oz/ft^2. That is to say, G90 galvanized steel are coated by the weight of zinc 275g/m^2 while G60 galvanized steel are 180g/m^2.
Therefore, G90 galvanized steel are more 95g/m^2 zinc coating than G60 and then a longer service life.

 

3.What are galvanized steel coil used for?
Hot dipped galvanized steel coil are most produced to roofing sheet for construction and houses.

 

4.How are galvanized coils made?

5.How long will galvanized steel coil last?
The zinc coating of hot-dipped galvanized steel will last 10 to 30 years in the open environment. High humidity and temperature have less life time for galvanized steel coil.

 

6.Does galvanized steel rust?
Galvanized steel coil will take 10 year or more to rust, but it will eventually rust. Galvanized steel coil the layer of zinc on both sides. which can resit rust acts by preventing oxygen and water from the steel.
