Unistrut Defender is a corrosion-resistant coating designed for channel, fittings, clamps, and hardware. It provides a service life between Hot-Dip Galvanized and stainless steel. Unistrut Defender was tested against Hot-Dipped Galvanized by an independent, accredited 3rd party lab, for 3000 hours of continuous salt spray exposure per ASTM B117. The results showed that the Unistrut Defender coating is 3 times more corrosion-resistant than Hot-Dip Galvanzed.
