Structural Laminated Veneer Timber

offers numerous key benefits

High-penetrating surface treatment

Formulated to repel rain during storage and construction

Includes a biocide/fungicide

Paintable – acrylic and oil based coatings

Glueable – using standard construction adhesives between the LVL and wood or plaster products

When transporting or walking on the LVL, it does not become slippery like the wax surface coating

Environmentally friendly

Structural Laminated Veneer Lumber (LVL) is a high-quality engineered wood product that is widely used in construction for its strength and durability. In order to meet the quality controlled process requirements of AS/NZS 4357, timber manufacturers must adhere to strict guidelines and standards throughout the production process.

One key requirement of AS/NZS 4357 is the use of high-quality veneer layers that are free from defects such as knots, voids, and delaminations. These defects can weaken the structural integrity of the finished LVL product, so it is essential that manufacturers carefully inspect and select veneer layers that meet the specified criteria for quality.

Another important aspect of the quality controlled process is the use of an appropriate adhesive system that ensures reliable bonding between the veneer layers. AS/NZS 4357 sets out requirements for the type of adhesive to be used, as well as the application process and curing times. Manufacturers must follow these guidelines closely to ensure that the resulting LVL product has the necessary strength and stability.

In addition to the quality of the raw materials and adhesive system, AS/NZS 4357 also outlines requirements for the manufacturing process itself, including factors such as pressing conditions, temperature control, and moisture content levels. By carefully controlling these variables, manufacturers can produce LVL products that meet the high standards set out in the Australian and New Zealand standard.

Overall, compliance with AS/NZS 4357 is essential for ensuring the structural performance and safety of LVL products used in construction. By following the guidelines and requirements of this standard, timber manufacturers can produce high-quality LVL that meets the demands of modern building design and construction techniques.
