Massaranduba Siding
About Massaranduba Wood
Massaranduba is one of the hardest and most durable timber species in the world. It is considered a cost-effective substitute for Ipe decking in some applications. With a reddish brown hue and straight grain, it has been nicknamed “Brazilian Redwood.” It is naturally durable and resistant to rot and decay, making it an excellent choice for exterior applications. It not only lasts a long time, but has the beauty of an interior hardwood. Massaranduba is another popular natural alternative to PVC or composite products. It outlasts other popular wood decking species such as treated Pine, Cedar, American Redwood and Douglas Fir.
ETT stocks Massaranduba decking (Brazilian Redwood) as well as other parts to complete a deck, including: joists, stringers, treads, risers, skirting, railings and posts. We also mill tongue-and-groove (T&G) profiles, and offer custom millwork for special profiles or sizes. Massaranduba deck facing is partially air-dried (AD), and then kiln-dried (KD) to approximately 15% moisture content for stability. ETT also stocks all the accessories – fasteners, sealers, cleaners, and finishes – to complete your deck.
Massaranduba FAQ
What spans can I expect from Massaranduba?
Due to the strength of Massaranduba, you can expect the following spans:

- 5/4x (net 1″) – up to 24″ on center

How do I maintain that original dark, rich color?
Massaranduba will weather to a silver patina if you leave it in its natural state. Depending upon your exterior conditions, it can noticeably turn within a few months and can be fully gray within a year. Should you wish to keep the wood rich and dark, apply an oil-based UV inhibitor finish specifically designed for hardwoods such as Ipe. There are numerous available brands, and we recommend Messmer’s UV Plus for Hardwood Decks.
