Steel framing refers to the building technique with a basic frame of vertical steel columns and horizontal I beams, fabricated in a rectangular grid to support the floors, roof and walls of a building which are all attached to the frame. The construction of high rise buildings is made possible largely due to steel framing.
It is the high strength structural steel that allows the architects to actually bring to life the structures that they design in blueprints. Steel provides that strength and resistance to buildings which is hard to achieve with other materials in a cost effective way. The strength, durability, design flexibility and adaptability of structural steel make it the material of choice in building construction.
Cold roll forming is an extremely methodical and highly efficient mechanism to fabricate high strength steel. The process of cold forming employs a series of matching profile rolls driven in multiple stands, through which metal strip is passed without application of heat. Each pair of rolls progressively shapes the metal, until the final pair produces the required profile. The cold roll forming process adds a strain hardening impact in steel, thereby increasing the yield strength. The process can raise the yield strength of full sections to as high as 70% more than virgin metal yield strength.
Steel produced with the roll forming technique can be used in a variety of engineering applications including building construction, automobiles, electrical and general engineering works. Indeed, high strength steel is the most basic requirement of these industries and the most suitable way to produce the material is roll forming.
