It is available in grades based on face and back veneer quality from B to D, with a minimum F8 stress grade. Structural Plywood is a very stable and workable type of plywood The most common grades of structural plywood available are BB, CD, CC, and DD. Structural Plywood has proved to be both safe and reliable when used in commercial and industrial buildings, and is easily designed to resist the high loading criteria required by the building Codes. Its resilience and strength have been utilized in storage decks, truck floors and flooring in sporting complexes and agricultural buildings. Plywood flooring systems are a real cost effective alternative to suspended floors in such applications.
