At Keystone Ridge Designs, powder coating is more than a finish—it’s key to our commitment to durability, aesthetics, and performance. Our process creates a long-lasting surface built to withstand the elements.
Our Keyshield® Finish
Our exclusive KEYSHIELD® powder coat finish is a proprietary two-coat system designed to deliver exceptional product quality and long-term rust prevention. All Keystone Ridge Designs steel furnishings receive this industry-leading finish, applied to a durable 7–15 mil thickness for maximum corrosion resistance and surface protection.
The process begins with thorough substrate preparation. Each product is sandblasted to remove surface contaminants and create ideal adhesion. A corrosion-inhibiting phosphate coating is then applied, followed by a two-step powder application. The first layer is a zinc-rich epoxy primer, used exclusively on sandblasted parts for enhanced rust defense. The second layer is a colored polyester powder topcoat, chosen for its lasting color retention and resistance to weathering. Both coats are electrostatically applied and oven-cured, creating a non-porous, satin-like finish that’s smooth, consistent, and incredibly resilient.

E-Coating for Enhanced Protection
For projects in extreme or highly corrosive environments, e-coating is available as an optional pre-treatment to further enhance rust protection before powder coating is applied. This electro-deposition process coats the entire metal surface—inside and out—with a uniform, corrosion-resistant layer that reaches areas traditional spray methods cannot. When combined with our powder coating system, e-coating creates an added barrier against moisture, salt exposure, humidity, and temperature fluctuations, making it ideal for coastal regions, harsh winters, or high-exposure installations. E-coating is an added cost but provides an extra level of long-term durability where environmental conditions demand it.
