In the wire mesh industry, plain steel – or carbon steel, as it sometimes referred to—is a very popular metal that is commonly manufactured in both woven and welded wire mesh specifications. It is comprised primarily of iron (Fe) with a small amount of carbon (C). It is a relatively low cost option that is versatile and widespread in its use.

Plain steel wire mesh, whether it is available from stock or custom manufactured, is strong, durable and magnetic. Oftentimes, it is dark in color, particularly when compared to bright aluminum or stainless steel meshes. Plain steel does not resist corrosion and will rust in most atmospheric conditions; because of this, in certain industries, plain steel wire mesh is a disposable item.

Welded is an extremely popular type of construction for plain steel wire mesh. Welded construction usually applies to a relatively larger opening size.
