Natural and manufactured timbers

Types of timber-based materials and their uses

Timber comes from trees. Trees have to grow to full maturity (between 25 and 100 years) before they can be cut down for wood.

Hardwood

Hardwoods come from deciduous trees, which have large flat leaves that fall in the autumn. Hardwoods take longer to grow, are not easily sourced and are expensive to buy.

AshPale coloured, narrow grainFlexible and good for steam bending, tough, used for sports equipment
BeechSlight pink tint, close grainTough, durable and smooth to finish
MahoganyDark-reddish colour, very close grainCuts and polishes easily, gives a fine finish, used for high-quality furniture
OakModerate-brown colour with unique and attractive grain markingsTough and durable, polishes well, used for quality furniture
BalsaPale and wide-spaced grain due to it being a fast-growing hardwoodVery soft and easy to form, often used to make models

Softwood

Softwoods come from coniferous trees. These often have pines or needles, and they stay evergreen all year round - they do not lose leaves in the autumn. They are faster growing than hardwoods, making them cheaper to buy, and are considered a sustainable material.

SprucePale cream with an even grainEasy to form, takes stain colour well, used for construction and furniture

Manufactured board

Manufactured boards are usually made from timber waste and adhesive. To make them more aesthetically pleasing they are often veneered. They are cheap to buy.
