Tigerwood slab

For a long time all that Tigerwood was known much better throughout the world as Goncalo Alves or Muiracatiara. The wood has become a staple internationally as a unique wood that provides a very distinct look. Wood lovers understand that every single piece of wood is a one-of-a-kind and no species of wood shows that better than Tigerwood. Displaying its stripes as a slab is absolutely stunning. If the base color is wanted many slabs show up as only the base orang-ish hues of brown without all the wild streaking. Unlike any other wood out there, Tigerwood truly does come in many flavors. Here are 2 reasons why we like to use your tigerwood for creating wood slabs instead of only cutting it into lumber. Slabs have the highest yield of any form and using the most wood is imperative to sustainable harvest A slab that comes from a lesser quality log will be prone to be slightly less stable. Not many companies have thought of leaving Muiracatiara in slab form because of its high value as decking. We believe that offering some of our Goncalo Alves in the highest possible yield is imperative to keep our wholesalers competitive in an ever changing wood world. Our experience with Tigerwood means you can always be assured that we will supply you the very best. Give us a call or email us to see what we have available or what we are expecting to be available shortly. We can export our tigerwood slabs and lumber worldwide, direct from our FSC certified wholesale mill in Brazil.
