EXTREN® Product Logo

A product logo identification program was implemented by Strongwell after designers and specifiers of EXTREN® learned that problems were occurring because sellers or contractors were substituting look-alike shapes.

Since July 1, 1993, all EXTREN® fiberglass structural shapes and plate have been imprinted with the EXTREN® logo every three feet down the length of the part. Square and round tubes have the logo imprinted inside the shape. Small and unobtrusive, the logo assures customers that they are getting EXTREN® properties backed up by corrosion, mechanical and structural testing as conducted by Strongwell.
