PosMAC, or POSCO Magnesium Alloy Coating Product, is

 of the best Korean steel company, POSCO.

PARU has been using PosMAC for some parts of the Solar PV trackers.
because those trackers usually last for 20 to 30 years.

As PosMAC is remarkably resistant to rust and corrosion,
PARU's Solar PV trackers can stay durable and long
 despite of all bad weathers such as storms and winds.

Unlike galvanized steel sheets, PosMAC is steel that is covered with strong alloy
combined with magnesium, zinc, aluminum.

PosMAC is 5 to 10 times more resistant to rust and corrosion than existing ones.
It is such an innovation in the entire world that there is 
a type of steel that doesn't rust fast.

the POSCO website and Naver Magazine.
