Hard, tough, attractive grain and good weather resistance. Contains tannic acid which corrodes steel screws
Used in furniture,flooring,boats…
Ash
Tough, attractive grain, flexible
Used in tool handles ladders, sports goods and laminating
Mahogany
Interlocking grain -> difficult to work with and red
Used in indoor furniture and veneer
Teak
Straight grain and natural oils resist moisture,acids and alkalis
Used in outdoor furniture and traditional boat decks
Birch
Close grain, resists warping
used for furniture and indoor panelling
Beech
when steamed white when not, pink. Does not impart a taste onto food
used in chairs, chopping boards, tools
Pine
Straight grain, knotty, can contain resinous knots
Used in contruction work
Spruce
Straight grain, resistant to splitting
Used in indoor furniture
Larch
Grain fades to silver when exposed to the outside, good resistance to moisture
Used in outdoor furniture, fencing, decking
Cedar
corrodes ferrous metals, low density, sound dampening
greenhouses, beehives
Plywood
Thin layers of wood placed perpendicular to each other, strong in all directions, no grain weakness, an odd number of layers
Used in structural work, desktops, floorboards
Marine Plywood
Uses a water and boil proof glue and can be reistant to fungal attack
used in boats
Aeroply
High-quality plywood made from timber such as birch. Available in thin sheets, lightweight and easy to bend around a support frame.
Used in Gliders, laminated furniture, laser cut projects and jewellery
Flexiply
Plywood with two outer layers made from open grain timber allowing it to flex
Used in laminated furniture and curved panels
MDF
Compressed wood fibres sometimes urea formaldehyde is added as an additional resin. Available in standard grain or veneered with a layer of timber.
Used in model making, bookcases, cabinets and desks
Rough Sawn
When wood is cut to a basic size on a circular saw. The edges and sides are not smooth. This is usually the first stage of preparing wood for further, more accurate work. Rough sawn timber is cheaper. Rough sawn wood is often used on building sites, where the wood surface finish is not critical or not likely to be seen. A company/business that has a machine planer may buy rough sawn boards and plane them to size themselves, saving money. Standard stock sizes are 32mm and 50mm.
Planed square edge
wood that only has one edge that is planed accurately and the rest are rough sawn. Planing removes 3mm from original nominal size.
Planed all round
Wood has sides and edges that are all planed sqaure. The board is about 3mm small all round.
Natural wood
Only available to th emaximum width of the tree. To produce a wide product, wood planks need to be joined together. when joining planks, the end grains must go in opposite directions to ensure internal forces to not warp the wood to one side.
Manufactured Boards
Available in long, wide boards of uniform thickness. Not affected as much by temperature and humidity. No grain problems. Less expensive. Typical sheet size is 1220mm x 2440mm
