Abstract
The method of coating an elongated metallic member with a thermosetting plastic powder coating or with a thermosetting plastic powder undercoating and a thermoplastic powder outer coating, is significantly improved by passing the coated elongated metallic member through at least one induction coil to heat the metal and thereby the coating to the curing temperature of the thermosetting plastic powder and holding the temperature for the curing time. Curing temperatures, which depend upon the thermosetting plastic powder coating being cured, are sufficient to fully cure the material within seconds.
