Unique Self-Healing Properties

One unique characteristic of Unistrut Defender is that it contains self-healing properties. If the product is cut or scratched in the field, the finish will propagate into those areas eliminating the need for secondary touch-ups. This gives a sense of confidence that the material will provide lasting defense against corrosion in the field.


To achieve full performance and cost benefits, Unistrut Defender must be used as a complete metal framing system. In addition, Unistrut Defender should not be put in contact with stainless steel materials due to a dissimilar metals condition that will create galvanic corrosion.
