Timber Holdings USA says its Vanish Decking System completely conceals the fasteners underneath. The decking edges have a milled profile similar to a shiplap that hides the fasteners and allows the decking to shrink and expand with changes in moisture content. The coated stainless steel clips are stronger and more durable than typical plastic side-groove clips, the company says. While clips are blocked from view, water can still drain between the boards. Timber Holdings imports its Iron Woods decking, available in ipe, garapa, and cumaru. Timber Holdings USA, 414.445.8989, ironwoods.com
