These are two treatments that attach a zinc coating to the surface of the steel to prevent the occurrence of corrosion on the steel surface

It is a product obtained from hot rolled sheet by cold pressure processing. The surface quality of the cold rolled sheet is superior to that of the hot rolled sheet, and good mechanical properties can be obtained after heat treatment.

Seamless steel pipe is perforated by the whole round steel, and the steel pipe with no weld on the surface is called seamless steel pipe.

Galvanized steel does rust under certain conditions. The following are the reasons why galvanized steel plates may rust

Galvanized sheet refers to a steel sheet coated with a layer of zinc on the surface. Galvanizing is an economical and effective anti-corrosion method that is often used. About half of the world's zinc production is used in this process. In recent years, hot-dip galvanized steel sheets have been favored by many because of their good corrosion resistance, beautiful appearance, convenience for subsequent processing, cost reduction and environmental pollution. Overseas users are welcome, and galvanized products are widely used in construction, communications, electric power, transportation, energy, automobiles, light industry (home appliances), agriculture, animal husbandry, fishery, petrochemical and other industries.

​1. Basic composition of carbon steel plate
Carbon steel plate is a metal material composed of iron and carbon and several other elements. Normally, the carbon content of carbon steel plates does not exceed 2.1%, and also contains small amounts of sulfur, phosphorus, molybdenum, chromium and other elements. Because carbon steel plates have different compositions, they have different physical and mechanical properties.
