LVL Description：

LVL Timber ( Laminated Veneer Lumber) is an engineered wood product, It's made by bonding thin layers of wood veneer together with adhesives, and the grain of each layer runs in the same direction, unlike plywood.

 

compare with traditional solid lumber, LVL Timber is more straighter, stronger, and more dimensional stable than solid wood, making it suitable for structural applications like beams, headers, and columns.

It possesses sufficient flexural strength, compressive strength, and elastic modulus to meet the design load requirements for use as a support or keel.

 

Treated with moisture-proof adhesive, it can be used in humid environments (such as foundation formwork, outdoor scaffolding steps, and areas in contact with soil) for extended service life and potential for repeated use.

 

Why is it necessary to form lvl timber along the grain direction?

High Strength: Tensile, compressive, and flexural strengths are significantly higher than those across the grain.

High Stiffness: Resists bending and deformation (bending along its length).

Good Nail Holding: Nails or screws hold better when driven along the grain.

Susceptibility to Splitting: Splitting is more likely to occur along the grain (i.e., along the length of the timber).

In Summary: Timber must be used along the grain in building structures (such as wall studs, floor joists, roof rafters, and beams in timber-framed buildings) and in scaffolding and formwork support systems. This is to leverage its high strength and stiffness along the grain to carry the primary compressive and bending loads.
