Our cold formed steel sections commonly known as hollow sections conform to Kenya Bureau of Standards KS 02 – 104. Hollow sections are manufactured on a tube mill using high frequency induction welding technique. The strip is seam welded while round in shape and then gradually brought to the desired section in the sizing mill. The weld seam is put to a great amount cold working while being sized. This is a very severe test of seam weld and ensures that each length of hollow section is welded for maximum strengths.
