Massaranduba, also known as Brazilian Redwood, is a premium tropical hardwood sourced from Northern South America (Brazil, Suriname, Venezuela). With a Janka hardness rating of 3,190 lbf and a density of 68 lbs/ft³, Massaranduba is classified as Class 1 - Very Durable — one of the most durable commercial lumber species available. The heartwood exhibits deep red to reddish-brown with straight to interlocked grain, fine to medium texture, creating a striking natural appearance that improves with age.
Massaranduba lumber is valued for its exceptional durability, natural beauty, and resistance to the elements in demanding outdoor applications. Properly installed Massaranduba skirting fascia delivers a service life of 50+ years with minimal maintenance — an optional annual oil treatment preserves the original color, or you can let the wood weather to a distinguished silver-gray patina. Massaranduba carries a Class A - Low flame spread, making it suitable for wildfire-prone regions where code-compliant materials are required.
The 5/4 x 6 eased-edge (E4E) profile features gently rounded edges on all four sides, reducing the risk of splinters and creating a comfortable walking surface. This is the most versatile profile — suitable for face-screw installation with countersunk stainless steel fasteners. All Massaranduba lumber is available in Select and Better grade with lengths ranging from 4′ to 20′. For detailed step-by-step instructions, consult our Massaranduba installation guide. Long-term care recommendations are covered in our Massaranduba maintenance guide.
