Cumaru 1×6

Starting at: $4.42

A dense, golden-brown hardwood that delivers strength and beauty in every board. Ideal for decking, siding, and fencing in both residential and commercial builds.

 

 

Overview

Cumaru 1×6 is a reliable, high-performance hardwood with natural golden brown tones and a dense grain that resists moisture, insects, and daily wear. Also known as Brazilian Teak, Cumaru is nearly as hard and long-lasting as Ipe but comes at a lower price point, making it one of the best values for premium outdoor hardwood. The 3/4 inch by 5.5 inch profile is versatile enough for deck surfaces, cladding, fencing, soffits, and ceiling details. Each board is kiln-dried, FSC-certified, and milled S4S E4E for clean edges and smooth installation. Cumaru holds up in wet climates, full sun, and high-traffic spaces, making it a top choice for builders who want lasting quality without compromise.

IPE DECKING LOS ANGELES REVIEW

I started buying IPE from Brazilian Lumber over one year ago before the vendor opened the California location (i.e. where I am located). There were some issues related to the lumber (IPE), BUT the vendor made sure that all was taken care of and that I was happy. I mentioned “the issues” not to say that they product is bad, but rather to stressed out that the vendor provides superb service. No matter what you do, the problems may happen. Important is how such situations are handled. I was working with Luis, great guy to work with. I recommend this vendor.

I upgraded my backyard with Ipe deck tiles for my patio. It was definitely an investment, but it’s turned out to be worth every penny. The tiles were easy to install and the finished product is not only beautiful, but also incredibly durable and functional. I would highly recommend Ipe deck tiles to anyone looking to create a beautiful and long-lasting outdoor space.

Such a great find! I needed my side gate upgraded and Ed Shubin was so helpful in getting me just the right piece of lumber. He knew exactly what was needed according to my specifications! The lumber was top notch and I couldn’t be happier. Thank you Ed!

The best place to get Brazilian hardwood that I\’ve found anywhere in California or online. The customer service is very good, the reps are attentive to you upon arrival and they are very knowledgeable. The quality of wood is superb and the pricing is cheaper than I can find anywhere else.
