Plywood

Plywood is manufactured by attaching together several veneers, generally with a strong industrial-type glue. It is noted best for its ease of use as well as its relatively low cost and high degree of flexibility. Because the layers are reinforced atop one another, softwood can be used in its manufacture while still retaining strong durability and limiting its ability to crack or split. This means that weaker species of lumber can be used to make a strong product that can be acquired through local means rather than importing stronger hardwoods.

It is an Art

To aid in the prevention of splitting, the grains of the separate veneers are adjusted to run at perpendicular angles. This also helps prevent the wood from warping or otherwise becoming malformed. This also means that any side of the wood can be fastened with screws or nails while keeping the same level of endurance. The plies in any given sample are joined together with an odd number. This overall method of compositing is referred to as “cross-graining.”

Plywood Applications

Depending on the type of wood used in its production, there are many types of plywood with many applications. It can be used for anything from construction and flooring to crating and fencing. Plywood can be used to build scaffolds as well as various support structures, and is also used frequently in vehicular design from automobiles to boats and planes. It also has several smaller applications including stereo equipment and sporting goods.
