LVL Structural Wood Beam Straight Lumber

USED:

1) Suitable for various fumigation-free packaging; templates; and beams, rafters, and columns required for various building structures.

2) Wooden structural material, which can replace structural steel or reinforced concrete.

3) Packaging material for machinery and equipment.

PRODUCTION PROCESS锛歕r

LVL (Laminated Veneer Lumber) is a new type of structural material made by pressing together multiple layers of veneers glued together along the same fiber direction.

The manufacturing process of LVL is as follows: logs are turned into standard-sized boards, which are then cut into veneers; after drying, phenolic resin adhesive is evenly sprayed onto the joint surfaces of the veneers and aged; the aged veneers are laid flat layer by layer, with carbon fiber layers filled between the veneer layers; then, cold pressing, hot pressing, and finally, slitting, chamfering, and anti-corrosion treatment are performed to produce LVL boards.

LVL is mainly used in various packaging plants and wood product factories, especially suitable for export packaging of machinery, glass, and chemical products, as well as decorative wooden framing.

Structural laminated veneer timber (LVL) conforming to AS/NZS 4357 standards has performance characteristics meeting AS/NZS 4063.2 standards, thus satisfying the structural design requirements of AS1720.1 standards.

Structural LVL is manufactured using a Class A bonding process, resulting in a final product with formaldehyde emissions below 0.5 mg/L (equivalent to E0 grade).

LVL is available in a full range of sizes, from 95 x 45 mm to 220 x 75 mm. It conforms to AS/NZS 4357 (structural LVL) standards and is produced using industry-standard dimensions.

It is painted with “safety yellow/red/blue” for easy identification.

It can be used in concrete formwork support structures, such as joists, beams, purlins, and columns.

It is also suitable for edge slabs in concrete formwork frame projects and for cladding residential floor slabs.
