Our Powder Coating Process

We Have You Covered from Start to Finish

At Keystone Koating, we make it easy to get large volume powder coatings in the color, texture and thickness you want with fast turnaround times and attention to detail. Our commercial powder coating services begin with a personal consultation. We learn about your products and powder coating goals and discuss any special instructions for your order. From there, you will have a dedicated, in-house sales contact for the duration of the process that you can always reach for responsive action to your needs.

We count all incoming orders and inspect your products for damage, corrosion and residue. If we see any contaminants or damage that may affect the application of your coat, we will notify you before starting the coating process. Our team can recommend the correct preparation services to ensure your surfaces are ready for coating. Our commercial powder coating services are fully customizable, and we will help you create a solution to ensure the finished product meets all of your specifications.


If you have any previous coatings, corrosion, scale or other residues on the surface of your products, we will remove them fast — and without damaging your products — using high-performance abrasives blasting. Our sandblasting service provides metal scoring to create a stronger bond with your surface coat.

8 Stage Pretreatment

Before any large volume powder coating, make sure your products are clean and optimized with our eight-stage pretreatment system. This proprietary system also optimizes your products for high volume powder coating, using a chrome-free seal with zirconium applied and silane technology to improve the bond.

If your items have holes, threads, machined parts or other spaces you want to cover during large volume powder coating, take advantage of our expert masking services. We mask your items by hand using efficient methods and professional masking products to ensure total protection.

For steel and aluminum products intended for outdoor use, we recommend using a primer coat before proceeding with any large scale powder coating. Primer adds an extra layer of protection to your product and helps your finish coat look great up to four times longer than products without primer layers.

Our large volume powder coating services provide a fast application while ensuring a complete and even coat. We use a combination of manual and automatic sprayers depending on the profile of your item and adjust the electrical charge for maximum powder attraction and coverage.

To ensure your items are prepared to withstand the toughest climates, upgrade your custom powder coating process to include Super Durable polyester. Super Durable polyester powder coating offers great color and gloss retention, and will maintain a vibrant appearance under prolonged exposure to ultraviolet (UV) light.
