Classification and process of galvanized coils

　　① Galvanized coil immerses the thin steel plate in the molten zinc bath, and attaches a layer of zinc to the surface of the thin steel plate. At present, it is mainly consumed through the continuous galvanizing process, that is, the rolled steel plate is continuously immersed in the galvanized tank of zinc condensation to consume galvanized steel plate.

　　② Alloy galvanized sheet bending machine This steel plate is also hot-dipped, but it is heated to about 500 ° C immediately after coming out of the tank. The alloy galvanized sheet that constitutes zinc and iron has good coating adhesion and weldability.

　　③ The galvanized steel sheet produced by galvanized coil electroplating has good processing performance. However, the coating of galvanized pipe is thinner than that of hot-dip galvanized sheet, and the corrosion resistance is also poor.

　　④ Single-sided galvanized and double-sided differential galvanized coil single-sided galvanized steel sheet, that is, single-sided galvanized products have better compliance than double-sided galvanized sheet in terms of welding, painting, rust-proof treatment, processing, etc. In order to restrain the defect of not galvanizing on one side, a thin layer of galvanized sheet is coated on the other side, that is, double-sided differential galvanized sheet.

　　⑤ Alloy, composite galvanized coil This is an alloy made of zinc and other metals such as lead and zinc, and even a composite steel plate galvanized pipe steel plate not only has excellent anti-rust performance, but also has good coating performance.

On 25 November 2022 , 50 tons of Galvalume steel coil were delivered from Lianfeng Steel to Jakarta Port, Indonesia. The following is the whole process of order production and shipment.

The main purpose of color-coated board

Coated steel plate is also known as color-coated steel plate and color-coated steel plate. Color-coated steel plate is a kind of color-coated steel plate. Products made by rolling coating paint and baking and cooling after conversion treatment. The substrates of color-coated plates include cold-rolled substrates, hot-dip galvanized substrates, electro-galvanized substrates, and aluminum-zinc-plated substrates. The types of paint coating on color-coated plates can be divided into polyester, silicon-modified polyester, vinylidene fluoride, high weather-resistant polyester, etc. The production process has developed from one coating and one baking to two coating and two baking. Three coating and three baking processes have also appeared. There are many colors of color-coated panels, such as white gray, sea blue, orange, sky blue, crimson, brick red, ivory white, porcelain blue, etc. The surface state of color-coated panels can be divided into ordinary coated panels, embossed panels and printed panels. The market uses of color-coated panels are mainly divided into construction, home appliances and transportation.

We are located in China's industrial province - Shandong Province, on the verge of the Bohai Sea and the Yellow Sea, with convenient export and transportation conditions. Shandong Banghong New Material Co., Ltd. has diversified products.
