Hollow Structural Sections (HSS) are high-strength welded carbon steel tubes used as structural elements in building and bridge construction as well as a wide variety of manufactured products.
All HSS produced by Nucor Tubular Products is manufactured in accordance with the mechanical and chemical property requirements of ASTM A500, Grades B & C. We are also able to produce the newest HSS ASTM specification, A1085, as well as CSA G40.21 50W.
NTP provides one of the widest ranges of sizes and wall thicknesses of HSS in round, square and rectangular shapes. We’ve invested heavily in manufacturing technology to meet the toughest requirements for tight tolerances, straightness and material consistency.

HSS has a high strength to weight ratio, excellent compression support characteristics and excellent torsional resistance. When engineered and fabricated properly, it outperforms other material choices at a lower weight.
HSS is cost competitive with other structural materials. With improved connections and fastening methods, there is often a cost-advantage over other steel members and competing materials.
In exposed applications, HSS is an exciting, visual part of the design of buildings, bridges and other structures.
HSS is fire resistant and does not warp, twist, split, swell or shrink. It resists dry rot, mildew, termites and carpenter ants.
HSS provides uniformity of size, shape, strength and tolerances that make its use totally predictable.
HSS is made from steel, one of the world’s most recyclable and recycled materials.
HSS can be readily bent, formed, punched and drilled. New and improved methods of connecting HSS to itself or other materials are making use simpler and faster.
