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
industryso manufacturing facilities, processing plants,
large office buildings and stadiums," JMC director of marketing
and business development Jelani Rucker told AMM via
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 (
