CSSA Says G40e Not the Same as G40
Written by Sandy Williams
The Certified Steel Stud Association (CSSA) recently squared off against the Steel Framing Industry Association (SFIA) over galvanized coatings for steel stud. CSSA released a warning that G40e or G40EQ coated steel products are not a substitute for G40 coated steel studs.
G40 is a hot-dipped galvanized coating (99 percent zinc) that is used to prevent corrosion that has been used for thirty years. G40e and G40EQ are relatively new electro galvanized products that are a combination of a base metallic coating and an outer coating that chemically bonds to the base.
