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.
Why Choose 2x2 Massaranduba Wood for Your Railing?
Massaranduba railing components match your hardwood deck perfectly and provide a warm-to-the-touch graspable surface that aluminum and cable rail systems cannot offer. Properly installed 2x2 Massaranduba railing delivers a service life of 50+ years with minimal maintenance — an optional annual oil treatment preserves the original color, or you can let the Massaranduba 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 2x2 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.
