Plastic coating for ERFs

• ERF is experimenting with plastic powdered coatings on its truck chassis.
Several vehicles have now been produced with their main frame rails finished in a hard plastic coating instead of the usual priming paint.
ERF says that the powdered coating makes the frame more resistant to corrosion. The frame rails need to be fullydrilled for all fixings before coatings, however, which reduces flexibility for a relatively small volume producer like ERF.
The company says that any holes which do have to be drilled subsequently can be satis factorily protected with conventional sealants. It says the powdered coating is hard enough to be unaffected by bolting operations during an assembly, and that bolted joints will stay as tight as they normally do between conventionally-painted metal surfaces.
