Rare Earth Hardwoods mills Brazilian hardwood lumber surfaced four sides (S4S) to consistent, ready-to-install dimensions — the same dense, naturally durable species used for decking, roof decking, flooring, and general structural applications, cut to the tolerances contractors and mills expect.
Our S4S program draws from a rotating inventory of Brazilian species — Ipê, Cumaru, Massaranduba, Tatajuba, Garapeira, and Angelim Pedra among them — so you can match hardness, color, and budget to the job rather than settling for whatever a single species allows.
Every run is surfaced flat and square on all four faces to a consistent thickness and width, with moisture content managed for stable, predictable performance once installed. It's lumber that goes from pallet to job site without an extra pass through the planer.
We supply this line across the board: container-load wholesale orders for distributors, job-lot volumes for commercial contractors, and smaller retail cuts for individual builders and homeowners.
Ipê, Cumaru, Massaranduba, Tatajuba, Garapeira, Angelim Pedra and more — each suited to different load, color, and budget requirements.
Many species we mill S4S carry Janka hardness ratings well above 2,000–3,500 lbf, far exceeding common domestic decking and framing stock.
Surfaced four sides to a consistent thickness and width, with moisture content managed for stable performance after install.
Container-load wholesale orders, commercial job lots, and smaller retail cuts, all from the same inventory.

Rare Earth Hardwoods has supplied Brazilian hardwood lumber since 1984, sourced through our own Zero Impact Brazil facility and harvested sustainably and ethically, in compliance with all applicable regulatory agencies. You get dense, durable S4S lumber without an unaccountable supply chain behind it.
S4S stands for “surfaced four sides.” The lumber is milled flat and square on all four faces to a consistent thickness and width, so it's ready to cut, fasten, and install without additional planing.
Our S4S program regularly includes Ipê, Cumaru, Massaranduba, Tatajuba, Garapeira, and Angelim Pedra, among other South American hardwoods, depending on current inventory and your project's load, color, and budget requirements.
Yes. We supply container-load wholesale orders for distributors, job-lot volumes for commercial contractors, and smaller retail cuts for individual projects.
Many of the species we mill S4S — Ipê and Cumaru in particular — carry Janka hardness ratings well above most domestic species and are commonly specified for decking, exterior structural framing, and other load-bearing outdoor applications. Confirm species and grade against your local code requirements for structural use.
