What we do, who we do it for
Powder coating is an eco-friendly method of painting that requires no solvents and generates little or no hazardous wastes. The coating is applied as a dry powder and then cured as a solid, durable coating using heat or ultraviolet light.
We have been serving our customers’ coating needs since 1984, and we understand that cleanliness is the key to a successful process. The end result is an attractive finish that is harder and more durable than conventional paints. Powder coating can be used to create a wide range of finishes and textures, some of which are impossible to achieve with any other process.
Process & System
Three decades of consistent finish
Process
Powder coating is an eco-friendly method of painting that requires no solvents and generates little or no hazardous wastes. The coating is applied as a dry powder and then cured as a solid, durable coating using heat or ultraviolet light. The end result is harder and more durable than conventional paints, and can produce a wide range of finishes and textures impossible to achieve with conventional painting.
System
Our system is fully conveyer operated, and we utilize a six-stage pre-treatment system with separate dry-off and curing ovens to ensure the best quality possible. We offer precision masking and material prepping before the parts are painted, as well as additional silk-screening services. Quality control, light assembly, and packaging are also available right off the line.

Equipment Spotlight
On the coating line
Conveyer
Automated conveyer line
A 1,500-foot fully automated powder coating line moves parts continuously through six-stage pre-treatment, separate dry-off and curing ovens, and inspection and packaging straight off the line — running as Lights Out Manufacturing for consistent, unattended throughput.
Booths
Automated + manual booths
Automated booths with robotics handle high-volume production, while manual booths accommodate large and small jobs the line can’t standardize. Maximum part opening 42″ × 54″ × 108″.
