Timber is therefore a natural reinforced polymer.
1. Harvesting: Cutting down the tree in the forest
2. Conversion: Cutting the trunk and large branches into boards, slab and quarter sawn.
3. Seasoning: Reduce the moisture content either naturul or kiln seasoned.
4. Board pred: Sawing to size and planing; PAR - Planed All Round.
Quarter Sawn:
With quarter sawn there is more waste, but the sheets are more stable and less liable to warp. They also show much nicer grain structures.
Slab Sawn:
Slab sawing causes the wood to warp a lot more, but doesnt create as much waste.
When wood is sawn it is cut in inches, and when it is planed it is done in CM.
