The concept of cold rolling and hot rolling
Using continuous casting slabs or blooming slabs as raw materials, heating them in a walking furnace, removing phosphorus with high-pressure water, and then entering the rough rolling mill.

Advantages and disadvantages of hot rolled steel
By definition, steel ingots or billets are difficult to deform at room temperature and difficult to process. Generally, they are heated to 1100-1250 °C for rolling.

Characteristics and uses of hot rolled steel coils
Hot-rolled coils are made from slabs (mainly continuous casting slabs). The hot steel strip coming out of the final rolling mill of finishing rolling is cooled to a set temperature by laminar flow, and then coiled into a steel strip coil by a coiler.

Types and uses of hot rolled steel sheets
Hot continuous rolled steel sheet products include steel strips (coils) and steel sheets cut from them. The steel strip (roll) can be divided into straight hair rolls and finishing rolls (split rolls, flat rolls and slit rolls).

Process and characteristics of hot rolled steel
Hot rolling uses slabs (mainly continuous casting slabs) as raw materials, and after heating, strips are made by rough rolling mills and finishing mills. The hot steel strip coming out of the last rolling mill of finishing rolling is cooled to the set temperature by laminar flow

Why choosing the wrong color will make Prepainted Galvanized Steel Coil less useful
The durability of the coating is the performance of the color steel coil during use, which is usually measured by the aesthetic life and the first overhaul life.

What are the coating types of Prepainted Galvanized Steel Coil
Prepainted Galvanized Steel Coil is made of cold-rolled steel strip and galvanized steel strip (electro-galvanized and hot-dip galvanized) on a continuous line. One or more layers of liquid paint, after baking and cooling the resulting sheet.
