Latest Resource From the Steel Tube Institute Makes It Easy to Check Tolerances of Hollow Structural Sections
GLENVIEW, Ill., Nov. 19, 2020: The Hollow Structural Sections Committee of the Steel Tube Institute (STI) is introducing an updated technical guide, “Methods to Check Dimensional Tolerances on Hollow Structural Sections,” to help fabricators and service centers. Available on the STI website, the educational resource discusses in detail and illustrates the latest methods to correctly measure tolerances of hollow structural sections (HSS).
“Fabricators and service centers deserve to have the latest technical information at their disposal,” said Joseph Anderson, executive director of STI. “This comprehensive guide is the only source that shows how to check tolerances of hollow structural sections, helping ensure materials meet industry standards.”
The guide assists professionals in verifying compliance with American Society for Testing and Materials (ASTM) specifications. While it is written for the A500 specification, it may be used for verifying tolerances for A1085, A847, A1065 and other similar tubular specifications. The resource outlines instructions for checking tolerances for outside dimensions, wall thickness, length and straightness, squareness of sides, radius of corners, and twist of the member.
“Since measurement techniques are not included in the A500 specification, we want to clearly show how tolerances should be measured for HSS to negate the possibility of any discrepancies between our producers and their customers,” said Anderson.
HSS is often the most economical and attractive structural option due to its high strength-to-weight ratio, aesthetic appeal and less surface area for preparation.
About the Steel Tube Institute
The Steel Tube Institute was formed in 1930 when a group of manufacturers joined forces to promote and market steel tubing. Their goal was to mount a cooperative effort that would improve manufacturing techniques and inform customers about their products’ utility, versatility and competitive advantages. This, along with providing a forum for the discussion of issues impacting the industry, remains the focus of STI’s efforts. Learn more at steeltubeinstitute.org
