AISC Requests HSS Data from Independent Testing
Posted by Geoff Weisenberger on November 7, 2007 at 3:17 PM.

During the past few months, a number of companies in the U.S. and Canada, including producers of hollow structural sections (HSS) and steel service centers, have sponsored a limited number of tests by independent testing facilities on HSS material imported from China, as well as HSS material produced in North America. As a result of those independent tests, the companies have raised questions about the mechanical properties of the imported HSS, as well as the credibility and reliability of the documentation provided when the products entered the U.S. and Canada from some of the newer sources in our market.

“AISC has not been involved in any of this HSS testing. Nor have we thoroughly reviewed the test data,” said Roger Ferch, AISC president. “We believe it is premature to draw any conclusions from any of the tests that have been conducted.” It is important to note, however, that from the data we have been provided, AISC has not concluded that there is a building code issue.


AISC is seeking to compile all available test data from its members and others in the steel industry willing to provide their test data. We request anyone who has sponsored recent tests on imported or domestic HSS to please contact Roger Ferch at or 312.670-5401.
