Garapa, also known as Brazilian Ash, is a premium tropical hardwood sourced from South America (Brazil, Suriname, Guyana). With a Janka hardness rating of 1,650 lbf and a density of 53 lbs/ft³, Garapa is classified as Class 2 - Durable — one of the most durable commercial lumber species available. The heartwood exhibits blonde to golden yellow, darkening to honey amber with interlocked grain, medium texture, creating a striking natural appearance that improves with age.
Why Choose 1x6 Garapa Wood for Your Outdoor Flooring?
Garapa 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 1x6 Garapa outdoor flooring delivers a service life of 30+ years with minimal maintenance — an optional annual oil treatment preserves the original color, or you can let the Garapa wood weather to a distinguished silver-gray patina. Garapa carries a Class A - Low flame spread, making it suitable for wildfire-prone regions where code-compliant materials are required.
The 1x6 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 Garapa lumber is available in Select and Better grade with lengths ranging from 4′ to 20′. For detailed step-by-step instructions, consult our Garapa installation guide. Long-term care recommendations are covered in our Garapa maintenance guide.
