Simpson Strong-Tie alters corrosion warnings

Testing done by Simpson Strong-Tie has led the fastner maker to change its recommendations for steel connectors and fastners used with wood treated with preservatives containing ammonia.

Earlier this year, Simpson issued a letter announcing its in-house testing "concluded that there is no significant difference in corrosion activity in galvanized steel in contact with treatments with or without ammonia." As a result, it has changed its recommendations in favor of using hot-dipped galvanized and stainless steel connectors and fastners for preservatives such as ACQ and ACZA. Previously, it recommended only stainless steel for use with those preservatives.

Simpson is now revising its online materials to reflect the new recommendations.
