steel is cut to length before it enters the roll forming mill.) Unlike structural steel shapes that are hot rolled into shape, manufacturing of lightweight steel framing is carried out at ambient temperature, hence the term cold formed. A single typical mill in one working shift can produce 20 km of straight, highly uniform, accurate product.
