Hot-dip galvanized steel sheet process description

Hot-dip galvanizing, also known as hot-dip galvanizing, is a method by which steel components are immersed in molten zinc to obtain a metal coating. In recent years, with the rapid development of high-voltage power transmission, transportation, and communications, the protection requirements for steel parts have become higher and higher, and the demand for hot-dip galvanizing […]

What are the main problems of hot-dip galvanized sheet welding

The existence of the zinc layer brings some difficulties to the welding of hot-dip galvanized steel sheets. The main problems are: weld cracks and increased porosity, zinc evaporation and soot, oxide inclusions, and galvanized layer melting and destruction . Among them, welding cracks, porosity and slag inclusion are the main problems. Welding crack During the […]

The difference between hot galvanized sheet and cold galvanized sheet

Hot-dip galvanized sheet is hot-rolled galvanized sheet, 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-galvanized sheet is better than hot-dip galvanized sheet The thickness is thinner, the surface source quality is better, the process is more complicated, […]

Hot dip galvanized steel knowledge

Galvanized sheet refers to a steel sheet coated with a layer of zinc on the surface. Galvanizing is a frequently used economical and effective anticorrosion method, and about half of the world’s zinc production is used in this process. Hot-dip galvanized steel sheet has ideal corrosion resistance, forming, coating and other comprehensive properties, as well […]

What is the difference between color-coated steel plates of different materials

In the production of color-coated steel plates, in order to meet the needs of different use occasions, the materials are divided into many types, such as hot-dip aluminum-zinc color-coated steel plates, cold-rolled substrate color-coated steel plates, electro-galvanized color-coated steel plates, etc. What are the differences? 1. Cold-rolled substrate color coated steel plate Color plates produced […]

What are the forming methods of color coated sheet?

Roll forming is the most commonly used method for the production of building roofing panels and wall panels with color coated boards. Roll forming machines use a series of differently shaped rolls on a rack to press the steel rolls into the required shape. Color-coated steel sheet is pressed into various shapes according to the […]

Hot dip galvanizing process

Hot-dip galvanizing, also called hot-dip galvanizing, is a method of obtaining a metallic coating by immersing steel components in molten zinc. With the rapid development of high-voltage power transmission, transportation, and communications in recent years, the requirements for protection of iron and steel parts have become higher and higher, and the demand for hot-dip galvanizing […]

How to choose the thickness of color steel plate?

Color steel plates are often used in construction projects. It is indispensable today, but it is worth mentioning that there are many types of color steel plates and their thicknesses have individual differences. Many people do not understand the specific specifications. , How to choose the thickness of the color steel plate is even more […]

What is the difference between color coated plate and color steel plate

Color-coated sheet is made of cold-rolled steel sheet and galvanized steel sheet as the substrate. After surface pretreatment (degreasing, cleaning, chemical conversion treatment), coating is applied in a continuous method (roller coating method), and baked and cooled The product. The color-coated steel plate refers to the color-coated steel plate, and the color-coated steel plate is […]
