Besides the hole pattern choosing, the surface treament choosing is also very important, right surface treatment will help achieve the best effect as well as save cost.
Firstly, what surface treatment do we usually do?
Powder Coating Aluminum Expanded metal
PVDF Painting expanded metal
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.
we do not recomond anodized surface treatment, for the color will be easlily fade under the strong sunshine. only when customer choose the aluminum nature color, it is ok to use anodized finish. because the aluminum material will be more brighter and cleaner than the mill finish.
you will see the difference before anodizing and after anodizing as following:
