Hollow Structural Sections

Direct forming allows Caparo Tubes to provide deep rectangles rarely manufactured in the industry in such sizes as 2" X 12" and 3 ½" X 12", while all the time maintaining the flatness of sides and dimensional tolerance other mills have difficulty meeting. Caparo Tubes is one of the few tube manufacturers to roll 5/8 wall material; and we do so with shorter lead times. As well, Bull Moose Tube can roll 100 ksi steel for the demanding engineering projects of today.

At Caparo Tube the square or rectangle is directly formed from a strip of steel and then welded. Because of this process, no cold working of the flat sides is performed.

The amount of residual stress in the product is minimal. Conventional processes rely on cold working to increase the physical properties of yield and tensile strength allowing the tubular section to meet the minimum requirements of ASTM A 500. At Caparo Tube, our steel strip is purchased to meet the ASTM guidelines without having to hope that cold working will allow the product to conform to ASTM A 500 strength requirements. Our steel chemistry requirements are more stringent than ASTM minimum ensuring our product quality.

Direct form allows for fewer roll stations leading to faster changeovers from one size to another that results in more frequent rolling cycles. Caparo Tube is known for having the fastest cycle times on the most sizes in the tubing industry. In fact we schedule to roll most of our popular sizes every 3 weeks. As a result of direct forming, our HSS has tighter tolerances on twist, straightness, concavity and convexity. Another benefit of our unique process is minimal tooling time and costs for special and Hard Metric sizes.

HSS tube is available in:
• Squares
• Rectangles
