Rubberwood
Suitable for furniture, joinery, flooring, staircases,furniture, tables,interiors of hotels, bars, restaurants, cafés, kitchens and bathrooms,interior and shop fittings, worktops, table tops, butchers blocks, toys. Excellent for turning.
The natural color of rubberwood is one of the principal reasons for its popularity. The air-dry density is between 560-640 kg/m3 and it has good overall woodworking and machining qualities for sawing, boring, turning, nailing and gluing. It also takes fin.

Density : 600 - 650 kg/m3 at (12% m.c)
Volume Shrinkage Radia l: 1% Tangential: 1.4%
Compression Strength Parallel : 4641 lbf/in2
Perpendicular : 680lbf/in2
Hardness : 975 lbf

Rubberwood is one of the more durable timbers used in the manufacturing of today's home furnishings. As a member of the maple family, rubberwood has a dense grain character that is easily controlled in the kiln drying process.
Easy to saw, machine, plane, turne and bore. Easy to fi nish due to smooth surface. Nail and screw holding is equal to hardwood. As a member of the maple family, rubberwood has a dense grain character that is easily controlled in the kiln drying process.
         

Hard Maple
Suitable for furniture, joinery, heavy-duty flooring, dairy and laundry equipment, sporting goods, piano actions, panelling, plywood, veneering. Excellent for turning.
The wood is hard and heavy with good strength properties, in particular its high resistance to abrasion and wear. It also has good steam bending properties.

Specific Gravity: 0.63 (12% M.C.) Average Weight: 705 kg/m3 (12% M.C.) - Average Volumetric Shrinkage: 11.9% (Green to 6% M.C.)Modulus of Elasticity: 12,618 Mpa Hardness: 6450 N

Heartwood is non-durable and sapwood is susceptible to attack by furniture beetle. Defects caused by insects (pith flecks) are sometimes found. Heartwood is resistant to preservative treatment, but sapwood is permeable.
Difficult wood to work with moderate dulling effect on cutters. Wavy or curly grains require a reduced cutting angle. Pre-drilling required for nailing and screwing. Takes stain, glue and polish satisfactorily.
         

Soft Maple
Suitable for furniture, joinery, domestic flooring, dairy and laundry equipment, sporting goods, turning, panelling, plywood, veneering.
Soft maple is about 25% less hard than hard maple, has medium bending and crushing strength, and is low in stiffness and shock resistance. It has good steam bending properties.

Specific Gravity : 0.54 (12% M.C.)
Average Weigh t: 609 kg/m3 (12% M.C.)
Average Volumetric Shrinkage : 10.5% (Green to 6% M.C.)
Modulus of Elasticity : 11,308 MPa
Hardness : 4226 N

Heartwood is non-durable and susceptible to insect attack. Moderately resistant to preservative treatment, but sapwood is permeable.
Can be worked fairly well with hand and power tools, although has moderate dulling effect on cutters. Takes nails satisfactorily with care. Gluing results vary. Can be stained and polished to excellent finish.
         

Walnut
Furniture, cabinet making, architectural interiors, high class joinery, doors, flooring, and panelling. A favoured wood for using in contrast with lighter coloured timbers.
Walnut is a tough hard timber of medium density, with moderate bending and crushing strengths and low stiffness. It has a good steam bending classification.

Specific Gravity : 0.55 (12% M.C.)
Average Weigh t: 609 kg/m3 (12% M.C.)
Average Volumetric Shrinkage : 10.2% (Green to 6% M.C.)
Modulus of Elasticity : 11,584 MPa
Hardness : 4492 N

Rated as very resistant to heartwood decay, it is one of the most durable woods even under conditions favourable to decay. Sapwood liable to attack by powder post beetles.
Walnut works easily with hand and machine tools, and nails, screws and glues well. It holds paint and stain very well and can be polished to an exceptional finish. It dries slowly, and care is needed to avoid kilning degrade.
         

White Oak
Suitable for furniture, cabinetmaking, joinery, heavy construction, parquet and strip flooring, ladder rungs, plywood, veneers, panelling, railroad ties, shakes, shingles.
A hard and heavy wood with medium bending and crushing strength, low in stiffness, but very good in steam bending. Southern white oak is faster grown with wide growth rings, and tends to be harder and heavier.

Specific Gravity : 0.68 (12% M.C.)
Average Weigh t: 769 kg/m3 (12% M.C.)
Average Volumetric Shrinkage : 12.6% (Green to 6% M.C.)
Modulus of Elasticity : 12,273 MPa Hardness: 6049 N

Heartwood is durable and very resistant to preservative treatment. Sapwood is moderately resistant. Logs are subject to severe insect attack.
Pre-boring is advised, but takes nails and screws well. Gluing properties vary. Stains well and polishes to a good finish.
