Poly-Armour is different from anything else on the market due to its PVF or Poly-Vinyl Fluorine coat. This coating is actually a highly durable 'plastic' coating that is 'baked and cured' to the line. This provides extra protection from corrosion, debris, and road surfacing solutions. It also offers superior bend-ability without kinking.Underneath the PVF-coating is a double-wall, low carbon steel, copper brazed tubing which meets all international and U.S. requirements for brake tubing. The difference being that Poly-Armour offers 30 times the corrosion resistance of galvanized steel alone.
