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 5/4x4 Tigerwood Wood for Your Outdoor Flooring?
Tigerwood outdoor flooring is ideal for covered porches, screened-in rooms, and breezeway floors where a refined, interior-quality finish is needed in a weather-resistant package. Properly installed 5/4x4 Tigerwood outdoor flooring 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 5/4x4 tongue & groove (T&G) profile features interlocking edges that create a seamless, flush surface with no visible gaps. Ideal for porch ceilings, soffit installations, and covered porch floors. 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.
