What are the specific uses of galvanized sheet and cold plate sheet

Galvanized sheet. 1.Definition.

Galvanized steel plate is to prevent the surface of the steel plate from being corroded and prolong its service life, and a layer of metal zinc is coated on the surface of the steel plate, and this galvanized thin steel plate is called galvanized sheet.

2.Classification and use.

According to the production and processing methods, it can be divided into the following categories: Hot-dip galvanized steel sheet. A thin steel plate is immersed in a molten zinc bath so that a layer of zinc adheres to its surface.

At present, it is mainly produced by continuous galvanizing process, that is, the coiled steel plate is continuously immersed in the plating tank with zinc melted to make galvanized steel plate; Alloyed galvanized steel sheet. This steel plate is also made by the hot-dip method, but immediately after it is slotted, it is heated to about 500 degrees to form an alloy film of zinc and iron. This galvanized sheet has good coating adhesion and weldability; Electro-galvanized steel sheet.

The electroplating method is used to manufacture this galvanized steel sheet, which has good machinability. However, the coating is thinner, and the corrosion resistance is not as good as that of hot-dip galvanized sheet; Single-sided and double-sided differential galvanized steel sheets. Single-sided galvanized steel sheet, i.e. a product that is galvanized on only one side.

In welding, painting, anti-rust treatment, processing, etc., it has better adaptability than double-sided galvanized sheet. In order to overcome the shortcomings of uncoated zinc on one side, there is another galvanized sheet coated with a thin layer of zinc on the other side, that is, double-sided differential galvanized sheet; Alloy, composite galvanized steel sheet. It is a steel plate made of zinc and other metals such as lead, zinc alloys and even composite plating.

This steel plate has both excellent anti-rust properties and good coating properties.

Cold plates are mainly used in automobiles, light industries such as home appliances and other product manufacturers with high requirements.

Hot-dip galvanized sheet is hot-rolled galvanized sheet, and cold-dip galvanized sheet is cold-rolled galvanized sheet. In terms of material, the composition of the two galvanized sheets is basically similar. The difference is that cold-dip galvanized sheet is thinner than hot-dip galvanized sheet, the surface quality is better, and the process is more complicated. It's a little higher.

From the process point of view, the steel is sent to hot rolling by the casting billet and rolled into a plate of a certain thickness, such as a thickness of about 10mm, if the user has no higher requirements for the surface, thickness and mechanical strength of the plate, the finished product can be treated, such as galvanizing, directly **, is the hot plate. If there are higher requirements for the plate, then the hot-rolled plate will be sent to the cold-rolled line for re-processing, and after pickling, annealing, re-rolling and other processes, the cold-rolled plate with thinner surface and better mechanical properties will be obtained.

1. What are the differences between galvanized sheet and cold-rolled plate 1. The physical properties are different, and the galvanized sheet has good corrosion resistance and convenient construction, while the cold-rolled plate has high hardness and a very smooth surface. 2. Different materials: The main materials of galvanized sheet are hot-dip galvanized steel sheet and electro-galvanized steel sheet, while the main material of cold-rolled sheet is stamping grade cold-rolled plate. 3. The galvanized sheet is made of alloy products made by plating a layer of zinc on the surface of the steel plate through the galvanizing process, while the cold-rolled plate does not need to be heated during production, and the gloss of the surface is better.

Second, what to pay attention to when buying galvanized sheet 1, before buying galvanized sheet, we should pay attention to understand the brand, at present, there are many brands of galvanized sheet, the choice space is relatively large, try to choose a large brand galvanized sheet, the quality and other aspects will be more guaranteed. 2. After the galvanized sheet is bought, it should be stored in a dry place and not in a humid area, which will cause certain damage to the galvanized sheet. 3. When purchasing galvanized sheets, pay attention to check the surface of the galvanized sheets to see if there are stains, etc., if there is, it is best not to buy such galvanized sheets.

4. You can choose according to the specifications of galvanized sheet, and purchase according to the actual situation, if you buy galvanized sheet with inappropriate size, it will affect the use of galvanized sheet. Summary: What are the differences between galvanized sheet and cold-rolled sheet, I hope it will be helpful to you after reading, if you want to know more about relevant knowledge, you can note Qijia.com information.

The difference between galvanized steel sheet, galvanized sheet, and color steel sheet.

The difference between galvanized steel plate, galvanized sheet, and color steel plate is in appearance: galvanized is divided into flowerless and flowered; Aluminum-zinc plating is flowered, which is a special color pattern formed by aluminum-zinc alloy; Color steel plates are colored. The difference between color steel sheet, galvanized sheet, and aluminum-zinc sheet:

Galvanized sheet: refers to a steel plate with a layer of zinc on the surface. Aluminum-zinc steel plate:

It is an important alloy material often used in daily life. Aluminum-galvanized steel plate is composed of aluminum-zinc alloy structure, which is solidified by 55% aluminum, 43% zinc and 2% silicon at 600 high temperature Color steel plate: refers to the color coated steel plate, color coated steel plate is a steel plate with organic coating, which has the characteristics of good corrosion resistance, bright color, beautiful appearance, convenient processing and forming, and has the advantages of the original strength of the steel plate and low cost.

Distinguish. 1. The substrate is different.

Ordinary cold-rolled sheet is a product obtained by cold pressure processing of hot-rolled sheet. Due to the multi-pass cold rolling, its surface quality is better than that of hot-rolled sheet, and after heat treatment, good mechanical properties can be obtained.

2. The physical characteristics are different.

Hot-dip galvanized steel sheet is more resistant to corrosion than cold-rolled sheet. The characteristics of hot-dip galvanized steel plate are strong corrosion resistance, excellent surface, conducive to deep processing, economical and practical. The drawing properties of hot-dip galvanized steel sheet are not as reliable as cold-rolled sheets. Hot-dip galvanized steel sheet is not as easy to weld as cold-rolled steel plate, and the zinc layer is damaged during welding.

3. The physical characteristics of the surface are different.

One is galvanized white and the other is black. The hardness is about the same, the use of performance is larger, the general galvanized sheet is no longer processed after processing, because the base surface has good oxidation, and the cold-rolled plate is not good, but also have to do a good job of surface paint otherwise it will oxidize.

4. The process is different.

In the production process of cold-rolled plate, because it is not heated, there are no defects such as pitting and iron oxide scale that often occur in hot rolling, and the surface is high and the finish is high. Moreover, the dimensional accuracy of cold-rolled products is high, and the performance and structure of the products can meet some special use requirements, such as electromagnetic properties, deep drawing properties, etc. Galvanized sheet: refers to a steel plate with a layer of zinc on the surface.

Galvanizing is an economical and effective method of rust prevention that is often used, and about half of the world's zinc production is used in this process.

Whether it is galvanized sheet or cold-rolled sheet, it is still relatively common in our daily life. Although the panels all look similar in appearance, they are metallic in color. But there is still a certain difference between the two, and we need to distinguish between them.

1. The first difference is manifested in their physical properties, the choice of galvanized sheet, its surface corrosion resistance is relatively strong, and it is conducive to later processing, but the drawing performance of cold-rolled plate is slightly better, especially when welding, galvanized sheet is easy to be damaged, but cold-rolled plate is not easy to be damaged.

2. The second difference is in terms of performance materials, if it is a cold-rolled plate, it is a product obtained by hot rolling and then through cold rolling technology in the later stage, which needs to go through multiple steps, so it is slightly more complicated when processing, but it can get better mechanical properties.

3. The third difference is that in the process, the cold-rolled plate does not need to be heated in the production process, so there will be no defects, the surface quality is better, the gloss is stronger, and the size is more accurate. However, galvanized sheet is used in some rust removal methods, and the surface may lead to some pitting or oxidation.

4. The fourth difference is that their application ranges are different, and cold-rolled plates are generally widely used in automobile manufacturing or electrical appliances. Galvanized sheet is generally used in the construction industry, for example, this kind of sheet can be used in roof tiles, in addition, kitchen utensils can also be made of galvanized sheet.

Second, the difference between galvanized sheet and stainless steel.

Some people find that the appearance of galvanized sheet and stainless steel is also the same, in fact, there are certain differences between the two. For example, galvanized sheet is coated with a layer of metal zinc on the iron sheet, which can achieve a certain anti-corrosion effect. And there are two processes, one is cold plating, and the other is hot plating, after a long time of use, the zinc on the surface may fall off, but stainless steel does not need anti-corrosion, it is through trace elements, so as to change its composition, to achieve the effect of anti-corrosion, so the production process of the two is different.

Summary: Galvanized sheet is compared with cold-rolled sheet or stainless steel, there are certain differences, and the scope of application is also different, and we need to decide according to the actual needs when choosing.

In our daily life, especially in home decoration, we have a certain understanding of the materials of home decoration, so what is the difference between galvanized sheet and cold-rolled sheet that we usually see? Today, I will tell you about the difference between cold-rolled sheet and galvanized sheet? I hope it can help you, and interested friends can follow along to find out.

1. What are the differences between cold-rolled sheet and galvanized sheet?

1. First of all, the basic material of cold-rolled plate and galvanized sheet is not the same, ordinary cold-rolled plate has to go through multiple hurdles of cold rolling, the quality of the surface is better than that of hot-rolled sheet, and good mechanical properties are produced after treatment. The galvanized sheet is relatively hard, it is the material zinc plated on the surface of the metal, so their materials are completely different.

2. There is also a difference in the physical properties of galvanized sheet and cold-rolled sheet, galvanized sheet is more heat-resistant, the surface quality is better, and it is more economical and practical. The tensile strength of cold-rolled sheet is better, and its hardness is relatively strong, and the drawing performance far exceeds that of galvanized sheet.

3. The surface physical characteristics of cold-rolled sheet and galvanized sheet are also different. Galvanized sheets are available in white and black, and although they are about the same hardness, their performance is driven by a wide range of factors.

4. Generally, galvanized sheet will not be processed again after use, and cold-rolled plate also needs to make a layer of paint on the surface after use, otherwise the cold-rolled plate will be oxidized, and the galvanized plate is less easy to be oxidized than cold-rolled plate.

5. The process between cold-rolled plate and galvanized sheet is different, the surface quality of cold-rolled plate in the production process is better, the finish is relatively high, and it can meet some special requirements, while the galvanized plate is made of steel plate, which is relatively economical.
