It is a flat sheet of steel that is poured with molten steel and pressed after cooling.
It is flat, rectangular and can be rolled directly or shears from a wide strip of steel.
Steel plate is divided by thickness, thin steel plate <4 mm (the thinnest 0.2 mm), medium thick steel plate 4~60 mm, extra thick steel plate 60~115 mm.
The steel plate is divided into rolling, hot rolling and cold rolling.

Round steel belongs to carbon structural steel for construction and machinery, while square steel belongs to carbon structural steel for machinery. Both of them are simple section steel, and their section shapes are respectively round and square. Low carbon is mainly used for drawing wire, forging rivets, bolts, nuts and other metal products of raw materials. Medium carbon round steel and square steel are generally used to make mechanical structural parts.
