BUILD A SYSTEM THAT LASTS

The Atkore Defender coating has proven to be ideal for corrosive outdoor environments in many common applications including industrial facilities, rooftop supports, transportation, railways, parking structures, bridges, solar panel framing, walkways, platforms, railing, theme parks, and more.

To compare Atkore Defender against traditional Hot-Dip Galvanized products, an independent, accredited laboratory exposed samples of both systems to continuous salt spray for 3,000 hours in accordance with a leading industry standard for corrosion testing, ASTM B117. Results showed that Unistrut Defender samples lasted more than three times as long as Hot-Dip Galvanized samples. The coating also has a self-healing property that allows it to reprotect itself against most cuts and scratches.

ATKORE DEFENDER  =  BETTER PERFORMANCE:

  1. Up to 3X better protection against outdoor corrosion than Hot-Dip Galvanized
  2. Can maintain a rust-free appearance for years
  3. Self-healing coating can reprotect itself when cut or scratched

LOWER PROJECT & SYSTEM COSTS

The superior protection of the Atkore Defender coating extends the service life of the products installed in outdoor applications. This can greatly reduce the lifetime costs for the building owner through avoiding or minimizing replacement and maintenance needs.

The Atkore Defender system can also provide up to 40% savings on materials for many common applications by avoiding the need for stainless steel fasteners, and up to 10% in labor savings by avoiding the need to touch-up cut ends of the strut.

The Atkore Defender system includes Unistrut Defender coated fasteners, which are much easier to install than Hot-Dip Galvanized fasteners, and are generally much less expensive than stainless steel alternatives.

ATKORE DEFENDER  =  COST SAVINGS:

  1. Lifetime cost savings by avoiding replacement and maintenance
  2. Save up to 40% in material costs by avoiding stainless steel fasteners
  3. Save up to 10% on labor costs by avoiding cut end touch-ups
