Frequently Asked Questions

What is powder coating?

Powder coating is a resilient coating made of urethane, polyester, epoxy, or a combination of these three. Similar in appearance to paint, powder coating offers consistent appearance, minimal processing time, and can be applied across many industries, from light fixtures to earth movers.

Why is powder coating better than paint?

Powder coating is baked onto the metal part, forming a thicker layer of protection that is stronger and more weather-resistant, minimizing scratching, peeling and fading.

How much time does it take to get something powder coated?

We generally aim for a 7-10 day turnaround time. However, due to some variables in the coating process, it can take as long as two weeks.

What powder colors do you offer?

There are several hundred standard colors and textures to choose from, or we can have your color matched in a custom color lab for an additional charge. For faster turnaround and more competitive pricing, we have many stock colors to choose from. See our stock colors here.

Is powder coating environmentally friendly?

Much more so than paint. Powder is non-toxic and environmentally safe, emitting no or very few harmful VOCs. The entire process at Keystone Koating has been tailored with the environment in mind. Most of our waste water is evaporated. The most efficient burners and ovens are used in the drying and curing process. Excess powder is often reclaimed and utilized. Learn more here.

What's the largest size that can be powder coated?

As a general rule, our dimensions max out at 84″H x 84″W x 204″L. However, in some instances we can coat parts that are as long as 22 feet. See the product size capabilities at our Lititz and Mifflintown facility here.

What's the largest size that can be blasted?

Our blasting capabilities for grit blasting are 48″W x 17″T x 300″L. We also have a manual aluminum oxide room 72″W x 84″T x 228″L.

What is the smallest production run you'll contract?

We specialize in business-to-business medium and large runs, so small production runs (no less than 25 parts) should be repetitive runs.

Does my part need to be blasted before powder coating?

Many parts that come to us do need blasting before being coated. However, if a part is new, clean, and has no mill ⁄ laser scale or corrosion of any kind, we can coat it without any blasting.

What are your pick up and receiving hours?

Our docks open at 7:00 AM, and close at 4:00 PM, Mon – Fri.

How do I get my parts to you? Can they be sent by UPS?

You certainly can have them sent in by UPS or any other common carrier; we can also pick them up for you, or you can drop them off yourself.

How do I get a quote on my parts?

The best way is to bring your part to us for evaluation. However, if that is not feasible, you may use our online form. An attached drawing with measurements is required. An isometric drawing is extremely helpful.

Can you powder coat wood or plastic?

Keystone Koating specializes in coating metals. Steel, aluminum, cast iron, cast aluminum, zinc and stainless steel are the most common. We do not have the capability to powder coat wood or plastic.

Will powder coating fail if chipped or scratched?

While any scratch to bare metal is not desireable and does compromise the surface, our research has shown that when parts are processed through our proprietary 8 stage pre-treatment, the applied conversion coating greatly limits the creep of the scratch. In fact, our lab results have shown that an intentionally scratched part will, in some scenarios, rust completely through the steel before coating failure occurs.
In addition, if powder coating does get chipped or scratched, there are liquids that can be applied to repair the damage.
