The Difference between Coil and Extrusion Coatings

23 Sep.,2023

 

Take the Anaheim Regional Transportation Center for example. The design team chose 70% PVDF Fluropon coatings in Silver to finish the exterior metal wall panels. The time-tested coatings help preserve the metal panels and create a sheen finish on the transportation hub. 

This is just one example of PVDF coatings in our everyday lives. These coatings are used to finish metal building products such as fabricated panels, curtain wall and gutters. Different projects call for specific coating formulas to meet performance and design requirements.

Two main coating types are used to finish metal building products: coil and extrusion coatings. 

The biggest difference between coil and extrusion coatings is how and when they are applied. Coil coatings are applied to coiled sheets of metal before it is formed, while extrusion coatings are spray applied after the aluminum extrusion has been formed.

This article explains the processes for coil and extrusion coatings, provides case studies for each and overviews typical end uses.
