Lumberock - Marine Grade Decking

Our Company

Welcome to Lumberock® Marine Grade Decking

Over the last two decades, plastic composite lumber materials have become the standard alternative to traditional decking materials. Nevertheless, there are drawbacks to most brand-name composite boards that have made consumers wary of their effectiveness and long-term cost efficiency. Lumberock was developed in an effort to address these concerns and truly live up to consumers’ expectations of a synthetic lumber. Our goal was to create a composite deck board that really does last a lifetime with no maintenance beyond an annual cleaning. Through careful consideration of our customers’ needs, we understood that we needed to make a deck-board that was strong, durable and easy to install without compromising aesthetics. We also understood that we needed to create a product honorable of its lifetime warranty. Formed in 2000 and located northwest of Chicago, Illinois, Lumberock specializes in synthetic, composite lumber fabrication and product development. We value honesty, integrity and service. Thank you for your continued support of our product.
