In an effort to preserve a natural resource, this teak is plantation grown and harvested to preserve the natural teak trees which are becoming endangered today. The heartwood is a uniform golden brown without markings. Grain is usually straight to slightly wavy. Texture is coarse, uneven and oily to the touch, sometimes with a white glistening deposit. Weight varies from about 38lbs to 43lbs per cu. ft.

Medium bending and high crush strength. Low stiffness and resistance to shock. Fissile and brittle with great dimensional stability. Moderate steam bending characteristics.
Medium resistance to cutting tools with a severe blunting effect. Pre-drilling required for nailing. Gluing is good on freshly planed or sanded surfaces. Fine machine dust is a skin irritant. Stains well and takes a satisfactory finish, especially an oil finish.
Very durable. Susceptible to insect attack. Extremely resistant to preservative treatment.
Dries well, but slowly. Variations in drying rates can occur in individual pieces. Standing trees are girdled and left to dry for three years before felling. Small movement.
Extensively used in ship and boat building for decking, rails, hatches, etc. Furniture and cabinetmaking, flooring, garden furniture, chemical vats, fume ducts, laboratory benches, plywood, and decorative veneers.
FEQ: The highest grade of Teak available. Mostly clear boards, virtually free of sapwood. Wavy grain less than 5%. Free of pitch, bark, open knots. The market standard for high end yacht building were near perfect long/clear boards are demanded.
Premium: Mostly clear on one or more faces. No open knots, but small tight knots and pin knots are allowed. Best face to contain 95% or more of heartwood. Back face may allow a higher amount of sapwood and natural defects.
