Webinars On Demand: Measuring HSS Tolerances (June 2021)




HSS outside dimensions, wall thickness, corner radii, etc. – we strive to meet ASTM tolerances for these important dimensions. What tolerances are allowed for HSS? How do we ensure we are taking HSS tolerance measurements correctly? The Steel Tube Institute and its member HSS producers have developed a standard guide for measuring HSS tolerances. Fabricators, designers, and all within the HSS steel supply chain are welcome to join this free webinar as we summarize the required ASTM tolerances for HSS and step through videos demonstrating these measurements being taken.

Learning objectives include:

  • Explore the STI Tolerance Guide and how it serves as a standard for tolerance measurements
  • Summarize permissible production tolerances for HSS per ASTM standards, and tips to keep in mind for detailing
  • Discover how to properly take tolerance measurements through video demonstrations
