1,040 kg/m 3: 1,750 lb/cu yd Throughout India It contains ripe wood in the outer crust. The colour of this ripened wood is dark brown. It is strong, durable and fibrous. Palm is used for furniture, roof covering, rafters and joists. Pine: Pinus spp. Pine wood is hard and tough except white pine which is soft.
The density is typically between 500 and 1,000 kg/m 3 (31 and 62 lb/cu ft). [5] The range of density and classification as light-, standard-, or high-density board is a misnomer and confusing. The density of the board, when evaluated in relation to the density of the fibre that goes into making the panel, is important.
The density of hardboard is higher than 500 kg/m 3 (31 lb/cu ft), [4] usually about 800–1,040 kg/m 3 (50–65 lb/cu ft). [5] It differs from particle board and medium-density fiberboard in that the bonding of the wood fibers requires no additional adhesive, the original lignin in the wood fibers sufficing to bond the hardboard together, [ 6 ...

Softwoods such as pine are typically much lighter and easier to process than hardwoods such as fruit tree wood. The density of softwoods ranges from 350 kg/m 3 to 700 kg/m 3, while hardwoods are 450 kg/m 3 to 1250 kg/m 3. Once dried, both consist of approximately 12% of moisture (Desch and Dinwoodie, 1996).
Plywood is a composite material manufactured from thin layers, or "plies", of wood veneer that have been stacked and glued together. It is an engineered wood from the family of manufactured boards, which include plywood, medium-density fibreboard (MDF), oriented strand board (OSB), and particle board (or chipboard).
Moisture content of dried wood: 12 per cent; Density of wood: 560 kg/m 3; Tensile strength: 88 MPa; Modulus of elasticity: 9.1 GPa; After felled kauri wood dries to a 12 per cent moisture content, the tangential contraction is 4.1 per cent and the radial contraction is 2.3 per cent. Kauri is considered a first rate timber.
