The Patriot Docks Reinforced Poly 4'x4' (47 5/8" x 47 1/2") Deck Section can be seamlessly integrated into any 4 ft. frame with a support span of either 16 in. or 24 in. This deck section comprises four poly boards, each measuring 1'x4' (11 3/8"x47 5/8"), with four embedded aluminum slats. Constructed from UV-resistant material, the poly board offers exceptional durability and remains cool to the touch even under direct sunlight. Its textured non-slip surface ensures excellent traction while providing a gentle feel on bare feet. The slotted design facilitates efficient drainage of water and allows light penetration for marine vegetation beneath the dock. By securing four poly boards together using two aluminum stringers, a remarkably sturdy 4'x4' drop-in panel is created. With an approximate weight of 35 lbs, this deck section strikes an optimal balance between strength and portability.
