3mm laser grade Birch plywood sheet
Being a natural product, the colour/shade of wood will alter with each batch.
Every effort is made to supply flat sheets but unavoidable warping may occur. It may be necessary to tape the wood to the laser bed.
Plywood has a tendency to curl because the veneer is rotary peeled from cylindrical logs and the nature of the fibres will tend to revert to their original format: ie round.
This means that while there are manufacturing standards for length, width and squareness there are none for the flatness of plywood. Plywood of 12mm and less have fewer laminations so will be more prone to curling, both on account of the forces and tensions within the board and the board's relative weakness with respect to external forces during storage and transport.
We recommend customers try to keep stocks of plywood so the wood has sufficient time to acclimatise to their new environment. Where possible, please store where the tempeature/humidy is constant.
