what is LVL laminated veneer lumber

Introduction to LVL

LVL is Laminated Veneer Lumber, which is made by rotating or planing logs to make veneer. After drying and gluing, the billet is assembled according to the grain or most of the grain, and then laminated by hot pressing. According to the material, it can be divided into poplar LVL and pine LVL; according to the purpose, it can be divided into packaging level LVL, furniture level LVL, construction level LVL; it has the structural characteristics that solid wood sawn wood does not have: high strength, high toughness and good stability 3. The specifications are precise, which is 3 times higher than the solid wood sawn timber in terms of strength and toughness.
LVL advantage
The advantages of LVL board compared with solid wood sawn timber:
 1. The LVL board can disperse and stagger the defects such as scars and cracks of the log, thereby greatly reducing the impact on the strength, making it stable in quality, uniform in strength, and low in material variability. It is the most ideal structural material to replace solid wood;
 2. The size can be adjusted at will, without being affected by the shape and defects of the logs. The LVL sheet can be up to 8 meters long and the thickest can be up to 300MM. You can choose the size and size according to your own material conditions and cut it at will. 100%;
 3. The processing of LVL is the same as wood, which can be sawed, planed, chiseled, tenoned, nailed, etc .;
4. LVL has anti-insect, anti-corrosion, fire-proof, waterproof and other properties, mainly due to the corresponding pre-treatment or special adhesive during the production process;
5. LVL has extremely strong seismic performance and shock absorption performance and can resist fatigue damage caused by periodic stress;
 6. This product is environmentally friendly and pollution-free, and uses high-quality environmentally friendly adhesives in the production process; the formaldehyde emission is far below the national standard and reaches the standard of developed countries, which can ensure your health.
LVL other features
According to the practical results, it is believed that although some properties of veneer laminates are not as good as finished products, the veneer laminates cause the defects (knots, cracks, decay, etc.) of the logs themselves to be evenly distributed in the veneer laminates (LVL) Medium, the average performance is better than the sawn timber.
1. Creep performance, veneer laminates have good creep resistance;
 2. Fire resistance, LVL is better than steel;
3. Durability, the damage caused by the accelerated aging test of LVL is less than the damage of the glue layer when the finished materials are glued;
Production Method
Rotate the log into a specification board, and then cut the specification board into a veneer; after drying, use phenolic resin glue to evenly spray on the connection contact surface of the veneer and age it; tile the aged veneer layer by layer And make the carbon fiber layer between the veneer layers; then pre-pressed by the cold press, hot pressed by the hot press, finally divided, chamfered, and anticorrosive to form a veneer laminate.
use
LVL is mainly used for various types of packaging plants, wood products factories, especially for export packaging of machinery, glass, chemical products, etc. In addition, it is also widely used in container sills, building formwork members, building beams, carriage panels, furniture, floors, rooms Decorate wooden keel etc.
