In a lumber factory, an automated laminated veneer lumber (LVL) process supported by a lumber production line employing a cross-cutting and rip-sawing stage, a dip-coating stage, a spray-coating stage, a print-marking stage, and a stacking, packaging and wrapping stage. At the dip-coating stage, cross-cut and rip-sawed LVL product is automatically transported and submerged through a dipping reservoir containing clean fire inhibiting chemical (CFIC) liquid, and then wet-stacked and set aside to dry. Once dried, the dip-coated LVL products are returned to the production line and sprayed coated with a moisture, fire and UV protective coating at the spray-coating stage, and then passed through a drying tunnel for quick drying of the spray-coating to produce Class-A fire-protected LVL products. The Class-A fire-protected LVL products are stacked, packaged and wrapped at the stacking, packaging and wrapping stage into a package of Class-A fire-protected LVL products, ready for shipping.
