Have you ever wondered how Hollow Structural Sections (HSS) are made? Does the manufacturing process of HSS affect the way we design with HSS? Have you actually ever read an ASTM specification that covers the production of HSS?
Engineers don’t always have the luxury to fully investigate the products we specify and use in our designs. We rely on design manuals and codes to provide us with minimum knowledge to get us to the finish line. However, there are differences in the manufacturing methods for different types of HSS and pipe. Some of what is actually in these material specifications is important when designing with HSS, and understanding all of this will help avoid the pitfalls of designing with and sourcing the material.
In North America, there are several HSS and pipe specifications to choose from when designing structures. Each specification describes the manufacturing process for that particular product and the quality assurance/control requirements. In this webinar, we will go through the common specifications used in building construction, and highlight some of the specification requirements and how they affect design. We will also cover the manufacturing process for HSS and pipe. HSS is produced in a much different way than other steel products, such as wide flanges. You will see that each specification has its own peculiarities when it comes to manufacturing requirements.
