Shot Blast Steel Preparation
RUST and PAINT DELAMINATION is an all-too-common occurrence on edging materials. Not only does it look bad, it affects the integrity of your landscape installations. The conventional method of pre-washing and powder coating the steel does little to eliminate the rust and scale that causes the problem.
WE HAVE A BETTER WAY!
The J D Russell Company is the first and only landscape edging manufacturer in the nation to use the Blastec shot blast system. The process removes scale, rust and other contaminants from the steel prior to powder coating. Using a 3 stage process, the steel is shot blasted, coated with phosphoric acid, then powder coated. This enables the paint to adhere properly to the metal surface ensuring a professional look that lasts far longer than our competitors.
