GENERAL

Timber tongue and groove decking is a specialty lumber product, constituting an important part of modern timber construction, that can be used for many applications to provide an all wood appearance. Nominal three and four inch decking is especially well adapted for use with glued laminated arches and girders and is easily and quickly erected. To be suitable for its intended purposes, timber tongue and groove decking must be well manufactured to a low moisture content.
