Genarally if it is used for the ourdoor decoration, such as building facaded, or protective mesh. we will choose PVDF finish or Powder coated finish.  because these two finish have longer lifetime, no fade and paint off. because it has been baked in 180 degree and 230degree during the painting, they are very steady finish. 

at the same time, if customer persue longer lifetime, PVDF painting is the best choice. surely the unit price is also higher than the two others.
