ASTM A1085 is a spec for manufacturing hollow structural sections (HSS) that offers enhanced performance in seismic and other fatigue-related applications. Atlas Tube produces ASTM A1085 HSS in many shapes, sizes and wall thicknesses on a frequent rolling schedule, making them widely available throughout North America.
The ASTM A1085 specification has raised the performance level of HSS to meet the demanding needs of today’s structures. That’s because ASTM A1085 HSS are made with tighter tolerances, and all shapes have the same minimum and maximum yield stress — allowing for easier design and lower costs.
ASTM A1085 HSS provide a significant advantage for applications with seismic requirements (50% of all U.S. buildings), structures with dynamic loading and structures where member size matters. Specifically, engineers and contractors use them in buildings, bridges, towers, cranes, sign supports and poles, off-shore production and drilling platforms, roll-over protective structures (ROPS), falling object protective structures (FOPS), and amusement rides.
