Is plywood available in lengths greater than 3050cm?
and if so, where?


Plywood is made in larger sizes but is cut down for shipment, mostly
to 2440 x 1220mm (8ft x 4ft) with, exceptionally 3050 x 1525mm
available. To get sizes bigger than this you would need to buy
directly from manufacturers who are mostly in either Finland or
Canada.
