Lockdry® Aluminum Marine Decking

The #1 choice for long-lasting, water-tight marine decking.

What Is Lockdry® Aluminum Marine Decking?

Simply put… it’s revolutionary. Lockdry’s® patented locking seal and continuous gutter technology provides a gapless floor decking and roof covering with single-layer construction. It is the most superior decking material in the marine industry, unlike composite or wood, which over time become brittle and splinter, retain heat, and require constant maintenance. Lockdry’s® maintenance-free design eliminates the need for painting, staining, or waterproofing and is virtually stain and mar-resistant.

IMAGINE… a second story deck that completely waterproofs your space below.
