Description

1. FIELD OF THE INVENTION

[0001] This invention relates to improved laminated wood flooring suited for both covered and exposed floors of vehicular trailers. In particular, the invention provides for flooring that allows the use of wood species of low hardness to produce moisture and scuff resistant floor boards. 2. DISCUSSION OF THE BACKGROUND ART

[0002] Conventional wood flooring for over-the-road closed van trailers, truck bodies and containers is normally manufactured with hardwoods, such as oak, hard maple, birch, beech, ash, etc. Lower grades of green lumber at the thickness of 4 / 4 (nominal 1 inch) or 5 / 4 (nominal 1¼ inch) are used as the starting material. This lumber has a large amount of defects, which are not allowed in the flooring product. An average of more than 50% of the lumber is either discarded or lost in the flooring manufacturing process. The lumber is suitably dried in special drying chambers under controlled conditions to moisture content of about 8%. The dried...
