Laminated veneer lumber is a structural material made by processing wood into thicker veneers, drying, sizing, forming blanks along the grain, and laminating and gluing. Because it is basically formed along the grain, it is also called parallel plywood. Because it is similar to the performance of glued wood, it is also called veneer glued wood. Its manufacture is very similar to plywood.
This product has the following advantages: LVL can be produced from small-diameter wood, bent wood, and short logs, and the yield rate can reach 60-70%; since the veneer can be lengthened vertically, the length of the product is not limited; the production cycle is short, and it can be realized Continuous production; logs can be cut into veneers by rotary cutting, which can be dispersed and staggered to reduce the impact on strength. Therefore, LVL has uniform strength and good dimensional stability; The veneer is treated to make the product have anti-corrosion, insect-proof, fire-proof and other properties. Disadvantages: The cost of the product depends on the type and amount of adhesive; the product is mainly made of thick veneer, and the cracks on the back of the thick veneer are serious, which will affect the material and cause a decrease in strength.
