The milestones in the history of plywood:
Ancient Origins of Plywood: Archeologists have found traces of laminated wood in the tombs of the Egyptian pharaohs. A thousand years ago, the Chinese shaved wood and glued it together for use in furniture. Early modern-era plywood was typically made from decorative hardwoods and most commonly used in the manufacture of household items, such as cabinets, chests, desk tops and doors. Construction plywood made from softwood species did not appear on the scene until the 20th century.
Plywood Patented, Then Forgotten: The first patent for what could be called plywood was issued December 26, 1865, to John K. August 18, 1868, described Mayo¡¯s development as follows: ¡°The invention consists in cementing or otherwise fastening together a number of these scales of sheets, with the grain of the successive pieces, or some of them, running crosswise or diversely from that of the others¡¡±
1905: An Industry Is Born: In 1905, the city of Portland, Oregon was getting ready to host a World¡¯s Fair as part of the 100th anniversary celebration of the Lewis and Clark Expedition. a small wooden box factory in the St. Johns district of the city. Part owner and plant manager Gustav Carlson decided to laminate wood panels from a variety of Pacific Northwest softwoods. Using paint brushes as glue spreaders and house jacks as presses, several panels were laid up for display. Called ¡°3-ply veneer work,¡±
From Doors to Running Boards: The First Plywood Markets: During its first 15 years the softwood plywood industry relied primarily on a single market¡ªdoor panels. By 1929, there were 17 plywood mills in the Pacific Northwest and production reached a record 358 million square feet (3/8-inch basis).
