High-Strength Laminated Veneer Lumber (LVL) from China - Leading Suppliers & Factory AS/NZS 4357.0:2022
Laminated Veneer Lumber (LVL)
ProductsLaminated veneer lumber (LVL) is a high-strength engineered timber formed by bonding multiple thin wood veneers layer by layer using adhesives. LVL was developed to use new species and smaller trees that cannot be used to make solid sawn lumber.
Fatima LVL is a cost-effective and sustainable building material that provides high structural strength and reliability when used in structural applications.
This article discusses the features, properties, and applications of LVL in the construction industry.
Product introduction
ProductsHigh performance more sustainable alternative to lumber, Laminated Veneer Lumber (LVL) beams, headers and columns are used in structural applications to carry heavy loads with minimum weight.
Our structural laminated veneer lumber (LVL) is specially designed for use in concrete form work applications. Edges are painted red for moisture protection and easy identification. Our LVL edge is light, straight and more uniform than traditional alternatives, thus saving time and money.

Advantages
Major advantages of LVL include its dimension, shape, high strength properties and low cost. The size of LVL is not limited by log size, due to its manufacturing method. LVL is one of the strongest wood-based construction materials relative to its density.
Because it is manufactured with homogeneous quality that has a minimum number of defects or even distribution of defects, mechanical properties of the final product can be predicted. In general, LVL can be produced in different shapes depending on for what it will be used. It also has the great advantage of using wood resources efficiently.
Disadvantages
Conversely, LVL has several disadvantages as wood composites. Enhancement of strength properties of LVL by densification of veneer during the press is very limited.
Although its dimensional stability is better than solid wood, the product may result in some defect, such as warping, if it is not properly stored in the warehouse. Also, LVL requires high capital investment to have relatively low production cost. Therefore, high demand is necessary to have a profitable operation.
Architectural Roof Trusses
ChooseArchitectural timber roof trusses create strong visual impact. Often used as part of ‘cathedral ceiling’ systems, timber can be specified light or heavy to suit the chosen theme and style. They can be left natural or may be oiled, stained, painted or highly decorated, limited only by individual style and design preferences.
Using Fields
ChooseFraming
Since people began building simple shelters, wooden framing has played an important role in shaping structures of many kinds. One of the most popular types of wooden framing is known as lightweight timber construction.
Portal Frames
For buildings that require large spans and column free interiors, timber portal frames provide one of the most aesthetically pleasing solutions. Utilising modern engineering technology, portal frame design transforms timber into a highly effective, efficient and economical structural product.
LVL provides a cost-effective and sustainable building material, delivering high structural reliability and strength.
Frequently Asked Questions
FAQWhat is Laminated Veneer Lumber (LVL)?
Laminated veneer lumber (LVL) is a high-strength engineered timber formed by bonding multiple thin wood veneers layer by layer using adhesives. It is developed to efficiently utilize smaller trees and new wood species that cannot be used for solid sawn lumber.
What are the primary structural uses of LVL?
LVL beams, headers, and columns are used in structural applications to carry heavy loads with minimum weight. It is also designed for concrete formwork, framing (lightweight timber construction), and portal frames for large-span buildings.
What are the main advantages of using LVL over solid wood?
LVL offers predictable mechanical properties due to its homogeneous quality and minimal defects. Its dimensions and shapes are not limited by log size, and it provides high strength relative to its density while utilizing wood resources efficiently.
Does LVL have any disadvantages?
Yes, LVL can suffer from defects like warping if not stored properly in warehouses. Additionally, it requires high capital investment for production, and strength enhancement through veneer densification during pressing is limited.
How is LVL applied in roof trusses?
LVL is used in architectural timber roof trusses for cathedral ceiling systems. It can be specified in light or heavy structures and finished with oil, stain, paint, or decorative details to suit individual style preferences.
