Product Q&A

Q:Which is better, powder coated vs. paint or primer?

Powder coating finishes are much tougher and thicker than traditional liquid paint or primers. And because they use no harsh solvents like paint, there is zero off gassing or foul chemical odors that frequently are associated with traditionally painted finishes. The bottom line, powder coating is tougher, longer lasting and doesn't smell. Far superior to painted finishes.

Q:Can I get my stairs in custom colors?

Q:How can i get the price?

In order to prepare an estimate, all we ask is that you send us a drawing to estimate from.Typically we're looking for a floor plan style drawing with some labeled dimensions.
