PAINTING of EMMEGI SPA PRODUCTS

Grating fences are painted using a polyester powder applied on the metal at high temperature. Polyester powder, has the characteristic of being a thermosetting material: it is made of selected polyester resins that after application has excellent characteristics of resistance to atmospheric agents and ultraviolet radiation, thus guaranteeing colour stability and durability in outdoor environments.

Polyester powder gives the fence an aesthetically pleasing appearance and the uniformity of the colour chosen by the customer from a wide range of variations.
