Tigerwood, also known as Goncalo Alves, is a premium tropical hardwood sourced from Tropical Central and South America (Brazil, Colombia, Venezuela). With a Janka hardness rating of 2,160 lbf and a density of 58 lbs/ft³, Tigerwood is classified as Class 2 - Durable — one of the most durable commercial lumber species available. The heartwood exhibits golden to reddish-brown with dramatic dark brown to black stripes with interlocked to wavy grain, medium texture, creating a striking natural appearance that improves with age.
Why Choose 4x4 Tigerwood Wood for Your Timbers?
Tigerwood lumber is valued for its exceptional durability, natural beauty, and resistance to the elements in demanding outdoor applications. Properly installed 4x4 Tigerwood timbers delivers a service life of 40+ years with minimal maintenance — an optional annual oil treatment preserves the original color, or you can let the Tigerwood wood weather to a distinguished silver-gray patina. Tigerwood carries a Class A - Low flame spread, making it suitable for wildfire-prone regions where code-compliant materials are required.
The 4x4 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 Tigerwood lumber is available in Select and Better grade with lengths ranging from 4′ to 20′. For detailed step-by-step instructions, consult our Tigerwood installation guide. Long-term care recommendations are covered in our Tigerwood maintenance guide.
