Galvanized Steel Coils

Hot-dip Galvanized steel also known as gi coil, is defined as a carbon steel sheet coated with zinc on both sides. galvanized steel: continuous hot dipping and electro-galvanizing. The coating creates a strong rust resistance and prolongs the life of the steel coils.

Overview

Galvanized Steel Coils Overview

Galvanized steel coils are produced in two main processes: hot-dipped galvanized and electro-galvanized. It can be available in thicknesses from 0.13 to 0.8 mm and widths from 6 to 12.5 cm, with a maximum length of 10 feet (3 m) when unfolded.


Galvanised coil, a thin steel plate that is dipped into a molten zinc bath so that a layer of zinc adheres to its surface. A thin layer of zinc is applied to the steel to act as a barrier between the steel and the environment. The finish is applied by passing the steel through a molten pool of zinc at a high temperature. It is mainly produced by the continuous galvanising process, whereby coils of steel are continuously dipped in a bath of molten zinc to produce galvanised steel; alloyed galvanised steel. This type of stainless steel sheet is also manufactured by the hot dipping method, but immediately after leaving the bath it is heated to around 500°C to produce an alloyed coating of zinc and iron. This galvanised steel coil has good paint adhesion and weldability.


Key standards of Galvanized Steel Coils to be followed in the production of galvanized coils include EN 10346,DX51D (Europe), AASTM A653 (USA), Q195 (China). Manufacturers also have their own original standards.


Galvanized Steel Coils are represented by cold and hot-rolled coils with a zinc coating, which helps to protect the steel against atmospheric corrosion. Galvanized steel coils from KLS are successfully used in industries with stringent requirements for corrosion resistance, durability, strength, and appearance, and can be formed or have various coatings applied. The key standards to be followed for the production of Galvanized Steel Coils.

Uses

FAQ


What is galvanized steel coil?

For galvanized steel coils, the thin steel sheet is immersed in a molten zinc bath, and a layer of zinc thin steel sheet is attached to the surface. It is mainly produced by continuous galvanizing process, that is, the coil is continuously immersed in the molten zinc plating tank to make galvanized steel sheet; alloy galvanized steel sheet. This kind of steel plate is also made by hot dipping method, but it is heated to about 500°C immediately after being out of the tank to form a zinc-iron alloy film. This galvanized steel coil has good paint adhesion and weldability.


Advantages of Galvanizing

Galvanizing is one of the most effective and economical ways to protect bare steel from a corrosive environment. Not only does zinc act as a barrier between the steel and the environment, but it sacrifices itself in order to protect the steel sheet beneath. Sacrificial or galvanic protection occurs when two different metals come into contact and combine with water and oxygen. Zinc preferentially corrodes the iron in the steel. This protection prevents the steel from corroding in areas not covered by zinc. As a result, the spread of corrosion from cutting edges, drilling, etc. is minimized.


The production process of hot-dip galvanized coils

Cleaning grease, dirt, and paint from the surface of steel coils. Coils need to be uncoiled and welded for continuous processing.

Rinse off the cleaning solution.

Place in acid solution to remove oxidation skin.

Wash off the pickling solution.

Immerse the steel in a molten zinc bath and hold it for a period of time to galvanize.

Cool and roll the steel into coils for sale.


Hot-dip galvanized steel coil price

The galvanized steel coil price depends on the thickness of the zinc, the thickness of the steel coil, and the packaging method. If you want to buy cheap galvanized steel coils, please choose 20g/㎡ galvanized steel coils, 0.8mm thick steel coils, and simple packaging. Please visit Color Coated Steel Coil Prices: Influencing Factors or contact us for wholesale galvanized steel coil!


Galvanized sequin type

Galvanized regular sequins, galvanized 30g to 275g (g90). The thickness is from 0.15mm to 2.0mm. Ordinary spangle galvanizing can be used in hot and humid outdoor places. For example, fences, roofs, garage doors, etc.


Can galvanized steel coils be oiled?

Yes, it can be oiled. 8-20g per square meter. Oiling can prevent the galvanized sheet from oxidizing in a short time.


Do you accept the galvanized layer test?

Yes, Galvanized Steel Coils are tested for the galvanized layer. We can send samples of galvanized steel coils to the laboratory required by customers.


Galvanized steel coils application

The application range of galvanized steel coils is wide, and its advantage is that the anti-corrosion period is long. It is mainly used for home appliances, office boards, roof boards, car boards, buildings and color steel roll substrates.


Car plate

The use of car plates must be stamped first, and the steel plate is stamped into the shape and size required by parts.


Galvanized roof panel

The performance requirements of galvanized roof panels mainly include the mechanical properties of the material (tensile strength, yield strength, extension rate), coating performance (coating type, coating thickness and coating adhesion)


Appliance office board

Including air conditioners, washing machines, refrigerators, copies, etc., household galvanized plates are mainly used for general forming applications and stamping.


Matrix

Another use of galvanized steel coils is a substrate for color coating steel rolls. Color-coating steel rolls have polyethylene coating than galvanized rolls and are more durable.


The difference between hot-dipped galvanized steel coils and electroplating steel coils

Hot-galvanized steel roll. Immerse the thin steel rolls into the fuse of the zinc groove, and the surface is attached to a layer of zinc. At present, continuous galvanized technology is mainly used in production, and the rolled steel plates are continuously immersed into a galvanized galvanized steel coil in the melting galvanized groove.


There is a big difference between the amount of hot-dip galvanized plate and electroplating plate in galvanizing. The amount of hot-dip galvanized should not be too small. Generally, the smallest double-sided is 50-60g/m2, and the maximum is 600g/m2. The galvanized layer of the electroplating plate can be very thin, with a minimum of 15g/m2, but if the plating layer is thick, the production line speed is very slow, and it is not suitable for the technical characteristics of modern units. Generally, it is about 100g/m2. Because of this, the production of electroplating plates has been greatly restricted.


Hot-galvanized plates are generally thicker, about 10um, and strong anticorrosive ability. So it is a commonly used galvanized process. The electroplating plate is very thin, about 3-5um, the hot-dip galvanized surface is rough, and the light is severe. If there are bright flowers, the electroplatidascular layer is smooth and non-gloss (dirty).



Galvanized zinc flower type

The American ASTM A653 standard galvanized steel plate and coils have two different flower types

Ordinary zinc flowers are galvanized, galvanized 30g to 275g (G90). Thickness from 0.15mm to 2.0mm. Ordinary zinc flowers can be used for damp -heat outdoor places. For example, fences, roofs, garage doors, etc.


Galvanized zinc flower, such a shiny GI, 30g galvanized to 2755g (G90). The thickness ranges from 0.12mm to 0.25mm. It can also be used outdoors. Mainly exported to Southeast Asia and Africa. It is cheaper than GI with conventional sequins. This product can be processed later, such as processing into stone coating tiles.
