Difference between galvanized sheet and cold rolled sheet

Galvanized sheet: good corrosion resistance, easy construction, with high strength and high ductility of a good match, has become a kind of high strength, good formability of stamping steel.

The role and advantages of color coated sheet in detail

Color coated plate has a smooth outer surface and bright colors, which can add color to the building. At the same time, the surface coating of color coated panel has anti-corrosion, waterproof, fire prevention and other functions, which can effectively protect the building.

How to distinguish between galvanized sheet and cold rolled sheet

Galvanized sheet has a silver-white zinc layer on the surface, while the surface of the cold rolled sheet is gray. If no zinc layer can be observed, then it is likely to be a cold rolled sheet.

Color coated sheet types, colors and application areas in detail

Color coated sheet is processed by spraying paint on hot-dip galvanized sheet or alumina zinc plated sheet, after several times of spraying and baking paint. The substrate of color coated sheet can be cold rolled substrate, hot dip galvanized substrate or electro galvanized substrate.

The role of galvanized steel sheets

Galvanized steel plate is coated with a layer of metallic zinc on the surface to prevent corrosion and extend its service life. This type of zinc-coated steel plate is called galvanized sheet.

Color-coated steel coil

Color-coated steel coils are made by applying one or more layers of liquid coating onto substrates such as hot-rolled substrates, galvanized substrates, aluminum-zinc coated substrates, cold-rolled substrates, tin-coated substrates, and stainless steel substrates, after surface pre-treatment (degreasing and chemical treatment) using a roller coating method.

Color-coated steel plate

Color-coated steel sheets are produced on continuous lines using cold-rolled strips and galvanized strips (electro-galvanized and hot-dip galvanized) as substrates. After surface pre-treatment (degreasing and chemical treatment), one or more layers of liquid coating are applied using a roller coating method, followed by baking and cooling to obtain the sheets.

Analysis of the Color Coated Steel Market

According to the market monitoring by the Iron and Steel Information Research Center, the price of galvanized sheets in the Boxing market has generally increased this week (4.19-4.23). The price of Baogang produced 1.0*1250*C galvanized sheet is 5500 yuan (per ton, tax excluded, same below), which is the same as last week's price. The price of 1.5*1250*C galvanized sheet is 5500 yuan, unchanged from last week; the price of Bensteel produced 0.7*1000*C galvanized sheet is 5500 yuan, unchanged from last week, and the price of 1.0*1000*C galvanized sheet is 5450 yuan, unchanged from last week; the price of Hengtong produced 1.0*1000*C galvanized sheet is

Trends in the Development of Coated Steel Sheet Production Technology

1) The use of high-quality substrates: The requirements for the surface, flatness, and dimensional accuracy of substrates are becoming increasingly stringent. For outdoor use, small zinc flower flat hot-dip galvanized steel coils are generally used, and it is best to use flat hot-dip galvanized steel coils without zinc flowers; in recent years, the trend of zinc alloy hot-dip coils is increasing. For indoor use, electro-galvanized steel coils can be used. Film-coated color plates use cold-rolled plates, and sanitary ware uses aluminum plate coils. 2) Improve the pretreatment process and pretreatment solution. A small number of devices and low costs have become mainstream processes, continuously improving the stability and corrosion resistance of the pretreatment solution. South Korea has used Cr+3 pretreatment solutions, and Japan has developed Cr+6-free pretreatment solutions.
