Atlas Tube manufactures a range of steel hollow structural sections (HSS) for structural applications. We offer round, square and rectangular HSS in the broadest range of sizes and gauges, with a variety of value-added services. Our quick-change technology allows us to offer the shortest cycle times in the industry. And with five mills across North America, we produce more than 1 million tons per year.
ASTM A1085 is the spec for today’s structures, allowing for greater efficiency, predictability and savings. These HSS are particularly well-suited for applications with seismic requirements (50% of all U.S. buildings), structures with dynamic loading (such as bridges) and structures where open floor space matters.Learn more about ASTM A1085 HSS
