What is Galvanized Steel Coil?
Galvanized Steel Coil, a thin steel coil is immersed in a molten zinc bath to adhere a layer of zinc to its surface.
In the past, Hot-Dip Galvanized Steel and Color-Coated Steel Coils dominated the coating industry and were widely used. Now galvalume steel coil also popular. These three products dominate the coating industry. Choose the corresponding product according to the different requirements of customers.
The Advantage of Galvanized Steel Sheet Coil
The main advantages of Galvanized Steel Sheet Coil are strong corrosion resistance, excellent weather resistance, good economy and good processing performance. In terms of service life, Galvalume Aluzinc Steel Coil are better than Prime Hot Dipped Galvanized Steel Coils, and PPGI/PPGL are better than the former two. Similarly, the longer the service life, the higher the cost, so the economy of galvanized coils is very good.

Big Spangle and Zero Spangle
There are two types of zinc spangles in Galvanized Steel Coil GI, one is big zinc spangles and the other is zero zinc spangles. The main difference is the corrosion resistance. Zero zinc spangles are processed by the galvanizing process, and the surface is flat and smooth without raised zinc spangles. Therefore, it has better corrosion resistance.
Regular Spangle
Zero Spangle
Surface treatment
Passivation
Passivation treatment of the galvanized layer can reduce folding rust (white rust) under moisture storage and transportation conditions.
01
Oiling
Oiling can reduce the steel plate's corrosion. After the passivation treatment of steel plates and strips, repainting oil will further reduce corrosion under humid storage conditions.
02
Lacquer seal
Coating a fragile transparent organic coating film can provide an additional anti-corrosion effect, especially fingerprint resistance. In addition, it can improve lubricity during molding and serve as an adhesion base layer for subsequent coatings.
03
Phosphating
Various coating types of galvanized steel sheets can be coated through phosphating treatment without further treatment except for regular cleaning. This treatment can improve the coating adhesion and corrosion resistance and reduce the risk of corrosion during storage and transportation. Finish phosphating can be used with a suitable lubricant to improve molding performanc

Competitive advantage
The Soul for Galvanized Steel Coil
Strong anti-corrosion ability
GI Steel coil are coated with a layer of zinc on the surface of steel, and the electrochemical properties of zinc are used to form a dense protective film, which effectively prevents the steel from direct contact with oxygen, moisture and corrosive substances in the air, thereby greatly extending the service life of the material. This anti-corrosion mechanism is not only suitable for general environments, but also exhibits good anti-corrosion ability even in humid, rainy or coastal areas with high salt content.
01
Good weather resistance
The zinc layer of the Hot Dip Galvanized Coils has good weather resistance, can resist the erosion of natural environmental factors such as sun and rain, is not prone to oxidation, corrosion and other problems, and maintains the stability and beauty of the appearance.
02
Smooth and beautiful surface
The surface of the Galvanized Iron Coil is smooth and flat, with uniform color and good decorativeness, which is suitable for occasions with high requirements for appearance.
03
Good processing performance
The galvanized coil has good plasticity and weldability, which is convenient for various processing and connection operations, such as cutting, bending, stamping, etc. It has high flexibility and is suitable for manufacturing complex shape parts and precision structures
04
Good economic efficiency
The anti-corrosion performance of Galvanised Steel Coil extends the service life of the material, reduces the frequency of replacement and repair, and reduces long-term maintenance costs. In addition, its production process is mature and the market price is competitive.
05
Application
At present, the most widely used are the construction industry, roof tiles, roof tiles, door panels, etc. Then there are the home appliance industry, the automobile industry and so on.

PACKAGE
In the past two years, the ocean freight rate has fluctuated greatly. Many customers use bulk cargo instead of container transportation. In order to better protect the steel coils, we have upgraded the packaging, with an inner layer of moisture-proof paper, followed by a sleeve-type plastic sheet (to better protect the coils and prevent seawater from entering), iron sheets, and packing tape.
