Abstract
A method of producing packaged bundles of Class-A fire-protected lumber for use in wood-framed building construction. The method involved maintaining a dipping tank in a lumber factory, containing a water-based clean fire inhibiting chemical (CFPC) liquid at a depth sufficient to cover pieces of raw lumber while being treated during dip-coating operations. Untreated lumber pieces are submerged into the dipping tank, piece by piece, in an automated manner to coat all surfaces of the lumber pieces in CFIC liquid, and then removed from the dipping tank to produce pieces of Class-A fire-protected lumber having a CFIC liquid coating. The Class-A fire-protected lumber pieces are automatically wet stacked, packaged and wrapped into a packaged bundle, and allowed to dry.
