Laminated Veneer Lumber (LVL): Strengths and Applications in the Construction Industry

Laminated Veneer Lumber (LVL) is a remarkable construction material that has gained significant popularity in recent years. This engineered timber product boasts impressive structural strength while contributing to sustainability in the construction industry. In this blog post, we will delve into the features, properties, and applications of LVL, shedding light on its versatility and importance in modern construction projects.

Features of Laminated Veneer Lumber (LVL)

Structural Composite Lumber

Laminated Veneer Lumber belongs to the category of Structural Composite Lumber (SCL). It is composed of dried and graded wood veneers, strands, or flakes.

Bonded Layers

To create LVL, thin wood veneers are carefully layered and bonded together using moisture-resistant adhesives. What makes LVL distinct is that these veneers are stacked in the same direction, ensuring that the wood grain runs perpendicular to the length of the billet.

Manufacturing Process

The veneers used in LVL production are less than 3 mm thick and are crafted using a rotary peeling technique. These veneers undergo meticulous treatment, defect scanning, moisture content analysis, and are clipped to a width of 1.4 m for LVL production.

Preservative Treatment

LVL can be susceptible to decay when exposed to high moisture content or used in unventilated areas. Therefore, it’s essential to treat LVL with preservatives to protect it against decay or infestation in such applications.

Versatile and Workable

LVL is highly versatile and can be easily worked with standard tools. It can be sawn, nailed, drilled, and holes can be made for service installations.

Diverse Thickness and Length

Sheets or billets of LVL are manufactured in various thicknesses, ranging from 35 to 63 mm, and lengths can extend up to 12 meters, offering flexibility in construction design.

Fire Resistance

LVL exhibits fire resistance similar to solid timber, with a slow and predictable charring rate. This rate may vary depending on the timber species used and the size of the member.

Ideal for Beams

Due to its consistent veneer orientation, LVL is particularly well-suited for beam construction. LVL beams excel in carrying heavy loads over long spans.

Advantages of LVL

Exceptional Strength-to-Size Ratio

LVL boasts an outstanding size-to-strength and weight-to-strength ratio. Even smaller-sized LVL components can exhibit greater strength compared to solid lumber, making it an efficient choice.

High Versatility

It is the strongest wood-based material relative to its density. Additionally, LVL can seamlessly complement other wood-based products like plywood, lumber, or oriented strand board (OSB).


Manufacturers can produce LVL in almost any size or dimension, offering architects and builders the flexibility to meet specific structural requirements.

Predictable Mechanical Properties

LVL is manufactured using wood materials with homogeneous quality and minimal defects. This ensures that its mechanical properties can be reliably predicted, enhancing safety in construction.

Tailored Fabrication

LVL can be custom-fabricated based on structural demands, making it a versatile choice for a wide range of construction applications.

Applications of LVL in Construction

LVL’s versatility extends to its various applications in construction:

  • I-Joists, Beams, and Columns: LVL is commonly used in the construction of I-Joists, beams, and columns due to its high tensile strength.
  • Lintels and Roadway Signposts: LVL’s durability and load-bearing capabilities make it an ideal choice for lintels and roadway signposts.
  • Formwork and Floor Bearers: LVL is employed in formwork and floor bearers to provide robust structural support.
  • Trusses and Purlins: The strength of LVL makes it a preferred material for constructing trusses and purlins.
  • Header and Rim Boards: These critical components in framing structures benefit from LVL’s reliability.
  • Pitched Rafters: LVL’s consistent quality and strength make it suitable for pitched rafter construction.


Laminated Veneer Lumber (LVL) stands as a testament to innovation in the construction industry. Its remarkable features, exceptional strength, and versatility have made it an integral part of modern construction projects. From beams and columns to trusses and formwork, LVL’s wide range of applications continues to shape the way we build, offering durability and sustainability to construction endeavors. When handled and stored correctly, LVL proves to be an invaluable asset in the construction toolbox, reinforcing structures and advancing the industry towards a more sustainable future.
