The Atlas Observer is Atlas Tube's dedicated resource for structural engineers, architects, and fabricators working with Hollow Structural Sections (HSS). Published by Atlas Tube — North America's leading HSS producer — the Atlas Observer covers ASTM specification comparisons (A500, A1085, CSA G40.21 and beyond), practical structural design guides, and deep technical insights on connection design, design wall thickness, new design tools, and seismic applications.
At a Glance: An Environmental Product Declaration (EPD) is a standardized, third-party verified document that quantifies a product's environmental impact across its entire life cycle, giving engineers crucial product data. For structural engineers and LEED project teams, facility-specific EPDs replace conservative industry averages...

Read moreAt a Glance: HSS delivers a higher strength-to-weight ratio in compression than wide-flange sections, reduces fireproofing and coating surface area by up to 50%, and o...
Read moreAt a Glance: ASTM A500 is structural tubing — Hollow Structural Sections (HSS) — manufactured for load-bearing applications and backed by a Mill Test Report (MTR) verifying yield strength, tensile strength, and elongation. ASTM A513 is mechanical tubing built for dimensional precision, with no physical property reporting required. Specify A...
Read moreEvery large structure, from soaring skyscrapers to sprawling bridges, relies on a solid foundation to establish structural integrity and safety. For projects demanding foundational support in challenging soil conditions, deep foundation systems are critical. Among the list of reliable solutions is straight-seam ERW steel...
Read moreAt a Glance: ASTM A500 defines cold-formed carbon steel structural tubing in round, square, and rectangular shapes — the standard for most HSS used in North American structural projects. Grade C is the most widely specified grade, delivering 50 ksi yield for square and rectangular sections and 46 ksi for round. Its closed geometr...
