Why Choose Massaranduba for Dock Decking
Massaranduba dock decking is the hidden gem for serious dock builders. At 3,190 Janka with 67 lbs/ft³ density, Brazilian Redwood delivers Ipe-level structural performance for docks — but at a lower price point with a unique deep reddish-brown color that no other dock wood provides. For commercial docks, marinas, and heavy-traffic piers where maximum strength matters, Massaranduba is the intelligent specification.
The marine borer resistance of Massaranduba is excellent — Class 1 durability with proven performance in marine environments. Like Ipe and Cumaru, Massaranduba requires no chemical treatment and leaches nothing into your waterway. The dense, tight grain provides a splinter-free surface with excellent wet traction for barefoot safety on docks.
Massaranduba dock lumber excels in heavy-duty applications: commercial marina finger piers, public fishing piers, fuel dock platforms, and any dock that handles heavy equipment or crowd loading. The 67 lbs/ft³ density means these boards have real substance — you can feel the weight and quality when you handle them. A Massaranduba dock lasts 50+ years in marine environments, rivaling Ipe at a more accessible price.
