Mild Steel Flat Bar is a versatile product commonly used in fabrication. With a flat surface and square edge, Sizing is represented as Width x Thickness, for example 40 x 25 = (45 mm Wide x 25mm Thick).

SAE 1030 is a plan carbon steel containing nominally 0.30% carbon. It is used in the hot-rolled, normalized, oil-quenched-and-tempered or water-quenched-and-tempered condition for general-purpose engineering and construction. It provides medium strength and toughness at low cost.

Product can be purchased in individual lengths or as a bundle and we can also cut to length.
