Unistrut Defender
Unistrut Defender is the newest, proprietary corrosion resistant finish by Unistrut. Defender is designed for harsh environments, providing an average service life between Hot-Dipped Galvanized and stainless steel systems. Unistrut Defender is 3 times more corrosion resistant than Hot-Dipped Galvanized products. 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.
Why use Unistrut Defender?
- 3X the performance of Hot-Dip Galvanized
- Corrosion-resistant
- Low maintenance — eliminating the need to replace parts over time
- Avoids costly stainless steel hardware
- Unique self-healing properties
- Similar pricing to Hot-Dipped Galvanized Steel, with a performance close to stainless steel
