  • P2655- Powder Coat Green

    Perma-Green® III / Powder Coat Green (GR) — A thermoset acrylic finish that provides superior resistance to chalking, checking, and fading and is far less vulnerable to common acid atmospheres, solvents, and alkalais. Perma-Green offers more corrosion resistance than the plain finish but offers less protection to the elements than pregalvanized, hot dipped galvanized, and Defender finishes.Please Note: We also offer volume discounts on larger orders. Please contact Unistrut Service Company for a custom quote on your bulk order.
