Product Description

Product Introduction

Galvanized steel coil is a material produced by continuous hot-dip galvanizing process with hot-rolled steel strip or cold-rolled steel strip as the substrate. Hot dip galvanized coil supplied in coil form after coiling. Therefore, galvanized steel sheet (coil) can be divided into hot-rolled galvanized sheet coil and cold-rolled hot-dip galvanized sheet coil. They are mainly used in the fields of construction, household appliances, automobiles, containers, transportation and household industry. Especially in steel structure construction, automobile manufacturing, steel warehouse manufacturing and other industries. Their main characteristics are: strong corrosion resistance, good surface quality, benefit from deep processing, economy and practicality, etc.
Galvanization is the leading method to protect metals from environmental elements that cause corrosion, rust, and the eventual weakening of the steel. Hot-dip galvanizing deposits a thick, robust layer of zinc iron alloys on the surface of a steel item.When exposed to the atmosphere, pure zinc reacts with oxygen to form zinc oxide which further reacts with carbon dioxide to form zinc carbonate. A dull, grey, fairly strong material that stops further corrosion in most circumstances, protecting the steel from the elements. Galvanized steel is widely used in applications where rust resistance is needed. Galvanized steel is commonly used in the automotive industry to enhance the corrosion performance of exterior body parts. Galvanized Steel is magnetic.

Dx51d, Dx52D, Dx53D, Dx54D Galvanized Steel Coil Manufacturer Gi Hot Rolled Steel Coils Zinc Coated Coil Advantages
1.Available for customized specification on customers' request.
2.Perfect Corrosion Resistance. The service life of galvalume is 3-6times as long as that of galvanized surface.
3.Perfect Processing Performance. Fully meet the requirement of roll processing, stamping, bending, ect.
4.Perfect Light Refelectivity. The ability of reflecting light and heat is twice that of galvanizing.
5.Perfect Heat Resistance. Galvalume products can be used at 315 degree Celsius for a long time without discoloration.
6.Excellent adhesion between the paint. Easy to paint and can be painted without pretreatment and weathering.

Galvanized Steel Coil Types
According to the processing method, we divide galvanized steel into the following categories:
1. Hot-dip Galvanized Steel Coil
As the name implies, hot-dip galvanizing is immersing the cleaned iron sheet into the molten zinc bath at about 500 degrees to form a zinc layer. It is the most commonly used method. It has some advantageous features:
1) The entire steel surface is uniformly covered with a zinc layer, even the corners, hollows, etc. so that the steel sheet is fully protected.
2) The cost of hot-dip galvanizing is cheap.
2. Electro-galvanized Steel Coil
Electro-galvanizing is a process of applying a layer of zinc to steel through electroplating, with a saline anode and steel conductor. It is able to enhance the corrosion and heat resistance of steel. Also, it makes steel sheets more good-looking.
