Plywood

 

Bamboo Plywood is constructed of bamboo strips that start our measuring approximately ¼” thick by 7/8” wide and are 6, 8 or 10 feet long. Bamboo is a grass and these strips have long fibers extending the full length or width of the board. These strips are bonded together in different ways to create different grain patterns and looks on the surface. If the surface layer is made up of the strips lying flat, rows 7/8” wide, it is referred to as flat grain or horizontal grain. If the surface layer shows the thin side of the strip, rows ¼” wide, it is referred to as edge grain or vertical grain. The strips are kiln dried prior to processing and this process determines the color of the finished product. The lighter color, a yellowgold hue, is called the natural color; if the strips are kiln dried longer, the color darkens and becomes an amber tone, sometimes referred to as carbonized or caramelized. If they are kiln dried even longer, the color is referred to as chocolate bamboo.

3-ply plywood is comprised of 3 layers laminated together. 3-ply bamboo plywood will have the flat grain or edge grain on both surfaces; the surface grain will run with the long side of the board. The center layer, or core, will have strips running across the width of the board. Structurally, this gives the board greater stability because there are long fibers running through the board in both directions. The thickness of the board is determined by the thickness of the layers and is available in ¼”, ½”, ¾” and 1” thicknesses. The 1/4 thick board is flexible and the rigidity of the boards increases with the thickness.

Single-ply, or solid bamboo plywood is made up of strips of bamboo on edge, with no cross-lamination, and is ¾” thick. Because there is no cross-lamination, it has the same grain all the way through and is commonly used for cutting trims and making stiles to compliment the 3-ply bamboo plywood. Single-ply bamboo boards do not have the stability of the cross-laminated 3-ply product, but can be supported or laminated to other materials in many projects.

Strand Bamboo, a dense material made of bamboo strands bonded together with a phenolic resin, can also be made into 3-ply bamboo plywood. A layer of the strand material, approximately 4mm thick, is used on both surfaces of the board with a cross-core constructed of bamboo strips. These boards are available in a dark brown color, called Havana and a golden tone called Sahara. The two colors can also be mixed in a random stripe pattern called Neopolitan. The density of the surface of these boards make them popular for use in areas that require enhanced durability.

Richlite Stratum is a blend of Richlite and Bamboo. This 3-ply product has a 1/8” layer of Richlite on both sides of a Plyboo Solid Bamboo Core. Standard Stratum features Black Diamond Richlite material on the surface that contrasts with the amber color of the bamboo strips in the middle. Dramatic effects can be achieved by accentuating the edge treatment of this unique product. Other Richlite colors can be special ordered for the surface.

3-ply palm plywood is constructed of strips of wood cut from the trunks of palm trees, coconut palms or sugar palms. Variations in the color and density of the palm strips add to the beauty of palm boards. The strips used to make palm plywoods are random is size; the wider strips, approximately 3” in width, are used on the surfaces of the flat grain boards and thin strips, approximately ¼” wide are used on the surface of the edge grain boards. The smaller and shorter pieces are used to make the cross-grain core. 1” thick edge palm lumber can be used to make trims to complement the 3-ply palm plywoods.
