2025 HSS SUMMIT
Session
HSS 102: HSS Materials Demystified: Key Specifications and Standards
Description:
After a quick review of the common manufacturing methods of Hollow Structural Sections (HSS), this session will go through the most common manufacturing specifications. This review will highlight the differenced and similarities between these specifications including topics such as mechanical properties, tolerances and testing requirements.
Learning Objectives:
- Explain the differences and similarities between the various manufacturing specifications.
- Identify the common testing requirements in each of the manufacturing specifications.
- Explain how the manufacturing specification influences the performance of the HSS.
- Determine the correct specification to use in specific applications.
