SS 40 galvanized fence framework is manufactured with cold-formed steel, which provides a high yield/tensile strength, followed by a uniform triple layer of corrosion protection. The coating consists of zinc, conversion coating, and clear organic topcoat applied in-line by Allied’s continuous Flo-Coat process. SS 40 is 20 percent lighter than Schedule 40 in gauge and weight, but it is as much as 33 percent stronger. Allied Tube and Conduit, Harvey, IL
