Aluminum

P&K uses several aluminum alloys, including 6063 and 6005 for
lighting arms and pole shafts, and 356 and 319 for base castings.
The advantages of aluminum include:

No rust or corrosion
Light weight for easier handling
Ability to bury directly where desired
Excellent recyclability
Safer in collisions, with better breakaway performance
Low deflection and vibration for better luminaire performance
Wide range of long-lasting color coating options available

Aluminum lighting standards have been proven in over 50 years of successful use in the harshest winter and coastal environments in the world, both on foundations and when directly embedded in the ground. P&K’s warranty covers its poles for 20 years.
