Plywood
Plywood is typically used in floor and partition panels. The plywood
core is much more durable than the balsa core, and is frequently
used in longer spans as a structural panel. The plywood core is
typically covered with stainless steel for floor panels, or with
melamine covered aluminum for interior panels.
Plywood comes in a variety of grades, which may vary in the panel
construction. A typical panel may have a grade A veneer on one side,
with a Grade B on the opposite side, and use grade C inner plies.
For applications in transit vehicles where the plywood surface will
be faced with a different material, an extrior grade B-B plywood is
suitable. (The exterior grade will include grade C inner plies).

| Purpose: |
This standard provides the requirements for producing, marketing, and specifying plywood for construction and industrial uses. (The specification value shown below requires exterior rated construction, with grade B faces, and grade C veneer underlying the B grade faces. This provides a suitable surface to bond the "skins" to.)
