Product Description

Product Description

Round steel is a hollow cylindrical metal material, which is widely used in construction, machinery manufacturing, automobile manufacturing, energy, transportation and other industries. Round steel is made in a variety of processes, including hot rolling, cold drawn manufacturing and cold drawn manufacturing.

Alloy round steels are characterised by a variety of features, notably high strength, high toughness, resistance to wear, corrosion, high and low temperatures. These features make alloy round steel excel in various industrial applications and are widely used in machinery, automotive and many other fields.
