Product Description:

 

 Prepainted  Zinc/aluzinc Steel Sheet In Coils

 

1.Structure of  Prepainted  Zinc/aluzinc Steel Sheet In Coils

 Structure of  Prepainted  Zinc/aluzinc Steel Sheet In Coils  are  coated with organic layer, which provides higher anti-corrosion property and a longer lifespan than that of galvanized steel sheets.

2. The base metals for Color Coated Steel Coil consist of cold rolled, HDG electro-galvanized and hot-dip alu-zinc coated steel. The finish coats of Color Coated Steel Coil can be classified into groups as follows: polyester, silicon modified polyesters, polyvinylidene fluoride, high-durability polyester, etc.

3. The production process has evolved from one-coating-and-one-baking to double-coating-and-double-baking, and even three-coating-and-three-baking.

4. The color of the Color Coated Steel Coil has a very wide selection, like orange, cream-colored, dark sky blue, sea blue, bright red, brick red, ivory white, porcelain blue, etc.

5. The Color Coated Steel Coil can also be classified into groups by their surface textures, namely regular prepainted sheets, embossed sheets and printed sheets.



2.Main Features of  Prepainted  Zinc/aluzinc Steel Sheet In Coils.

1) Rust-proof

2) Water-proof

3)Durable using

Q:Is the coil strip? Is hot rolled coil and hot rolled strip the same?
We found differences between strip and hot rolled strip width is below 1000mm, so it can be distinguished by the Ruifeng strip and Wuhan specifications eye coil, as to why some people use a strip coil, it depends on their factory mill can tie what width, this demand is also different.
Q:What's the difference between hot rolled strip and cold rolled strip? What's the difference between hot rolled coil and cold rolled coil?
The term "steel coil" is strip steel whose width is greater than 600mm and its width is less than 600mm. It is called "narrow band", so hot rolled coil is called hot rolled strip steel. As for the difference between hot rolled coil and cold rolled sheet, it is aimed at the rolling state of the steel plate. The hot rolled coil is made by rolling the hot rolled slab.
Q:What is the hardness of cold rolled steel strip?
Generally, the Rockwell hardness of annealed carbon steel is 55+-3, and the hardness of annealed cold rolled strip is above 80
Q:What's the difference between cold rolled strip and cold rolled strip?
Cold rolled steel sheets are made from hot rolled sheets at normal temperatures. Although they are rolled during processing, they can also cause steel plates to heat up. Nevertheless, it is called cold rolling. Because of the cold rolling of continuous hot rolling, the mechanical properties are poor and the hardness is too high. It must be annealed to restore its mechanical properties. Rolled rolls are generally used to make products without bending or stretching.
Q:What is the difference between steel strip and strip steel?
The difference is: the strip, that is used for processing into steel belt materials, iron and steel enterprise is produced by hot rolling cold rolling plate, a large volume of.
Q:What is the difference between strip and coil?
The coil is a thin steel sheet with a thickness of not more than 6 mm, usually less than 3 millimeters, but is rolled with a large mill due to its wide width. The width of the rolled strip is no more than 0.2 meters; the mill used is small, of course, the same thickness of the same material, the price of the coil is also more expensive than strip.
Q:1 can thick galvanized steel square pipe burn welding?
Galvanized square is a hot-rolled or cold-rolled galvanized steel or galvanized sheet for the blank shape by the cold bending process after section steel pipe welded square hollow square cross-section shape and size of the high-frequency; or the cold hollow steel well in advance of the re galvanized square by galvanizing processing of pipe.
Q:The degreasing time is too long, will the strip surface be oxidized?
Sheet metal pretreatment, degreasing total alkalinity is recommended in 15-20, alkali spent large, must be short time processing, for a long time will make the metal crystal nucleus passivation, influence phosphating film. Sheet metal general oil should not be cleaned, especially stamping parts, etc., it is recommended to use degreasing temperature, the temperature can be 65-75 degrees.
Q:Can cold rolled strip be plated with white zinc?
Sure。 Electroplating cold rolled plate surface is gray rust, after plating the cold rolling plate smoothness is higher than that of hot rolled plate.
Q:What are the advantages of cold rolling and cold rolling strip steel?
Cold rolled steel strip and sheet thickness is generally 0.1 ~ 3mm, width 100 ~ 2000mm in hot strip steel or timber as raw material, under normal temperature after cold rolling, cold rolled steel strip and sheet has the advantages of smooth surface, smooth, high precision and good mechanical properties.
