The Opportunity

Contractors, builders, and homeowners are impressed with the undeniable benefits of premium decking – durability, longevity, environmental safety, and low lifetime maintenance – and they find that the value it delivers is worth a premium price. Yet, as great as premium decking is proving to be, the structures underneath these new decks are still built using one of two equally unappealing choices: cheap, impermanent wood, and costly, unforgiving metal.
