Comparison of Hot-Finished and Cold-Formed Structural Hollow Sections

Members may have seen ‘Newsletter 50-740 Common use of S235 cold rolled steel instead of S355 hot rolled steel’ published by Confidential Reporting on Structural Safety (CROSS) in April 2018. The Newsletter reported that some local fabricators are purchasing S235 cold rolled hollow sections rather than the specified S355 hot rolled sections.

This AMM reminds members that hollow sections are manufactured for all types of applications from commodity up to offshore applications and therefore it is important to ensure the correct product is specified and purchased.
