Atlas Tube expands ‘jumbo’ HSS portfolio

Keywords: Tags  Atlas Tube, jumbo HSS, Nippon Steel & Sumikin Metal Products, Mitsui, structural sections, Thorsten Schier

NEW YORK — Atlas Tube Inc. has begun offering 18- and 20-inch square "jumbo" square hollow structural sections (HSS) in 0.375-inch wall thickness.

The same sizes were previously only available in 0.5- and 0.875-inch wall thicknesses.

The larger sizes can be used in vertical column and diagonal bracing applications, as well as in large, long-span trusses, according to Atlas, a subsidiary of Chicago-based JMC Steel Group Inc. They are also a solution for solving design challenges for structures with large load demands, such as those in areas of high seismic activity.

"The end market primarily calling for these new sizes was the nonresidential construction industry—so manufacturing facilities, processing plants, large office buildings and stadiums," JMC director of marketing and business development Jelani Rucker told AMM via e-mail.

The expanded offering is part of Atlas’ agreement with Nippon Steel & Sumikin Metal Products Co. Ltd. and Mitsui & Co. Ltd. to supply "jumbo" HSS to the North American market (, Feb. 22).
