Alro Plastics Product: Starboard® Family of Products

The King StarBoard® family of products has been used by nearly every boat manufacturer and by thousands of boat owners because of its durability and nearly endless applications. Now that the products have been proven in harsh marine environments, creative individuals and fabrication companies are finding dozens of new uses for the products, from outdoor kitchens and furniture, to theme park wet areas, to industrial rigging.

King StarBoard® ST has been recognized by the U.S. Green Building Council (USGBC) for Leadership in Energy and Environmental Design (LEED).
