The Guide to Selling Stuctural Plywood is designed to give clear advice on plywood types, their source and suitability for structural use. It also advises what standards and structural credentials to look for.

“An influx of imported plywood and the lack of a standardised grading system has led to confusion among merchants and customers about which types of plywood are suitable for structural use,” said BWF product manager John Fletcher.

He said this meant unsuitable plywood without structural grade could be sold for structural applications.

“Fixing non-compliant plywood can be a costly exercise for customers, as they are likely to be held liable for any defects or failures,” Mr Fletcher added.

The OSB guide outlines the differences between OSB 2 and structural OSB 3 and says it is vital to match the correct type to the right application. The guide also gives advice on storage and conditioning.

Further BMF guides are to cover chipboard flooring and structural timber.
