Roll forming machines are available in different shapes, sizes, number of spindles, and material thicknesses. Roll forming machines are energy efficient and they do not expend energy to heat the material. Roll forming machines are of various types such as single-duty roll forming machines, standardized roll forming machines, side-by-side roll forming machines, and double-headed roll forming machines.
