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:What are the categories of strip steel? How do you distinguish it?
Steel is divided into two major categories: carbon steel (carbon steel) and alloy steel by chemical composition. Carbon steel is an alloy obtained by smelting pig iron. Besides iron and carbon, it also contains a small amount of impurities such as manganese, silicon, sulfur and phosphorus. Carbon steel has a certain mechanical properties, but also has good technical performance, and low prices. Therefore, carbon steels have been widely used. But with the rapid development of modern industry and science and technology, the performance of carbon steel has not fully meet the needs, so people have developed a variety of alloy steel. Alloy steel is a multicomponent alloy obtained by adding certain elements (called alloy elements) on the basis of carbon steel. Compared with carbon steel, the properties of alloy steel have been improved greatly, so it has been widely used.
Q:How to drill through galvanized steel strip quality piercing eye
To distinguish the quality of galvanized strip is mainly from the aspects of surface finish / coating thickness / coating thickness difference / coating adhesion / salt fog test time and so on. GB 4175.2-1984 armored cables, galvanized steel strip, /GB-T 15392-1994, width less than 700mm, continuous hot-dip galvanized steel strip, etc., as you requested.
Q:Is there any difference between galvanized steel strip and galvanized sheet?
Broad sense means galvanized steel sheet.
Q:What are the high speed steel strips and material specifications?
Cold rolled carbon steel strip is made of high quality carbon structural steel by cold rolling. Because the cold rolled strip can be rolled to a specific heat, the rolling strip is thinner, and has higher dimensional precision and higher strengthCold rolled thin thick hot rolled instead for the same purpose, which can save about 30% steel. According to manufacturing accuracy can be divided into general accuracy (P), width accuracy higher (K), thickness
Q:What gas does the shear of the strip weld require for the welder?
Welding equipment includes welding machine and welding auxiliary mechanical equipment. According to the way of welding, it can be divided into two kinds of flash welding and welding.
Q:Why does the strip bend when it is rolled?
In the rolling process of strip tension is too large or too small will bring many adverse effects on the operation, including in the choice of a plan, must be properly chosen at each strip tension, if the improper selection of strip tension, will affect the quality of strip steel and the actual operation, when the strip coiler tension before and after the selection is too large that will cause the broken belt or rolled steel coil is heart-shaped, tension is too small will cause damage to roll off with Le roll or strip.
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:Is the strip steel strip?
Some thicker medium plate production is not produced by strip steel. In any case, the strip is a general term for strip and plate.
Q:65 what is the hardness of the best heat treatment of manganese steel strip?
65, the best heat treatment hardness of manganese steel strip depends on the application and heat treatment methods, such as the general in 45~50HRC, general heat treatment at 48 degrees, the best comprehensive mechanical properties.
Q:Pickling process of cold rolled strip
The continuous pickling line is divided into 3 sections according to the nature of the work:Inlet section: feeding, unwinding, strip surface, iron oxide crushing, straightening, shearing, shearing and welding;Pickling section: acid washing, hot and cold washing and drying;Exit section: shearing, oiling, and final take-up (take-up).
