With the development of the market, users of cold-rolled strip steel not only pay attention to the dimensional accuracy and mechanical properties of the products, but also put forward higher and higher requirements for the surface cleanliness of cold-rolled steel plates.

Hot-rolled steel is rolled at high temperatures. Cold-rolled steel plates have better strength, while cold-rolled hot-rolled steel plates have better ductility. Generally, the thickness of cold rolling is relatively small, while the thickness of hot rolling can be larger. Cold plates are used for cold-formed spring sheets and other parts. The thickness is pretty standard. When not rusty, it looks a bit bright like stainless steel; the hot-rolled surface is rough.

Dip galvanized steel sheets and coils are carbon steel made using a hot-dip galvanizing process. The end result of this process is a layer of zinc on each side of the steel plate or coil that adheres tightly to the steel by forming an iron-zinc alloy bonding layer.

Dx51d represents the grade or material of an ordinary galvanized coil.

Galvanized steel coil is steel sheet that has undergone a galvanizing process, which includes the application of a protective zinc coating to prevent corrosion. This process helps extend the life of the steel, making it more durable and resistant to harsh environments.

Galvanizing equipment is the key equipment for the production of such products, and its price composition involves many aspects. In this article, we will introduce the galvanizing equipment manufacturer's galvanizing equipment complete set of price composition in detail.

Intelligent hot-dip galvanizing production line is a kind of metal surface treatment process with high efficiency and environmental protection, in which the pickling and neutralizing water equipment is a crucial part of the production line.This article will introduce the pickling neutralization water equipment in the intelligent hot-dip galvanizing production line location, role and related technology.

Galvanized steel is generally coated with a layer of zinc on the outside of low carbon steel, and the zinc layer is generally 20um thick.

In the regular transactions of galvanized sheets, cold-rolled basic galvanizing is the main one, and hot-rolled base sheets are relatively rare. So, what is the difference between hot-rolled base sheets and cold-rolled base sheets? Let’s briefly explain it from the following aspects:
