Keystone Ridge Designs uses the highest caliber steel available in the market.
The powder coat finish is a patented process called Keyshield and protects products from time, weather and corrosion. The two-step Keyshield powder coating process is applied to a 7-15 mil thickness on all steel products. The trademarked process results in a non-porous covering on each product.
Each product is protected against chipping, cracking, UVA damage and corrosion. In addition, maintaining the finish is done with soap and water. A light buffing cream can be used to intensify the powder coat sheen.
Keyshield products are warranted against material and workmanship defects for three years from the date of purchase.
