How Plywood is Made

Plywood is composed of many layers, which are called plies or veneers.

The plies are created from 2 processes:

Rotary Cut
A log is spun on a roller and a big knife peels off the skin of the log.
(Just like peeling an apple).

Flat Sliced
The log is sliced into long thin slices lengthwise.
(Just like slicing a carrot from head to bottom)

The plies are then sandwiched together with a resin (glue) and pressed with enormous pressure.
The plywood is then cut into standard 4’ x 8’ lengths. Sometimes, depending on the customer needs the sheets can be as
big as 4’ by 20’ long. If the plywood has more plies, such as, Baltic Birch Plywood, it makes it very stable.
