CRF PROPERTIES

Cold-formed steel structural members are shapes commonly manufactured from steel plate, sheet or strip material. The manufacturing process involves forming the material by either press-braking or cold roll-forming to achieve the desired shape. No heat is required to form the shapes (unlike hot-rolled steel), and thus the name ‘cold- formed steel’. Cold- formed steel members and other products are thinner, lighter, and easier to produce, and typically cost less than their hot-rolled steel members.
