Unique 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.

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

*Duration of healing can vary depending on weather, location, type and size of application.
