1. Different corrosion resistance. Hot-dip galvanizing steel sheet is dozens of times colder galvanized . If hot-dip galvanizing is selected as the material of the steel bearing sheet, the service life of the steel bearing sheet can be increased, and subsequent maintenance costs can be reduced.
2. Ductility is different. The hot-dip galvanizing is more ductile than cold-dip galvanizing. During the pressing process of the steel sheet, the cold-dip galvanizing with poor ductility will break due to the pressing of the machine.
3. The thickness of galvanized layer is different. The thickness of hot galvanized layer is much larger than that of cold galvanized layer.
4. The price is different. The price of hot-dip galvanizing is higher than that of cold-dip galvanizing. Because the hot-dip galvanized sheet is used, the quality of the steel bearing sheet is good, so the price will be high.
Attention should be paid to heat treatment of galvanized square pipesGalvanized square pipes and fixtures should remove foreign matter such as oil, residual salt and paint before heat treatment.- Advantages and disadvantages of Galvalume steelSince its introduction, hot-dip Galvalume steel has been widely used in various industries such as construction and home appliances. Due to the continuous expansion of the scope of use, the product's formability and various properties of the steel sheet have been continuously improved, so the resulting aluminum-zinc steel sheet is superior to hot-dip Galvalume steel in some properties. Let's introduce it to you.
- What are the advantages of color steel coils?Color steel coil is a kind of composite material, also called color coated steel plate. It is made by using strip steel in the production line to continuously undergo surface degreasing, phosphating and other chemical transfer coatings, and then coated with organic coatings and baked.
- Introduction of steel pipeThe hot rolling of the seamless steel pipe is rolling at a temperature above the crystallization temperature, and conversely, for cold rolling, it is carried out below the crystallization temperature.
- What is the classification of galvanized sheet?Galvanized steel sheet is hot-dip or plated with a layer of metal zinc with a thickness of about 5-12 microns.
Types of galvanized steel
1. Hot-dip galvanized steel sheet
2. alloyed galvanized steel sheet
3. Galvanized steel sheet (also known as electrolytic plate)
4. Single-sided and double-sided galvanized steel
5. Alloy, composite galvanized steel - What is the material of aluminized zinc steel coil?The aluminum-zinc alloy structure of aluminum-zinc-coated steel coil is composed of 55% aluminum, 43.4% zinc and 1.6% silicon solidified at a high temperature of 600 ° C. The entire structure is composed of aluminum-iron-silicon-zinc, forming a dense quaternary crystal , Thus forming a strong and effective barrier to prevent penetration of corrosion factors
