Strength & Durability
The strength properties of LVLs come from the manufacturing process. During the process, the veneers (the individual sheets of timber that make up the LVL) will dry and the veneers are placed with the grains running in the same direction. The veneering process also randomizes any defects in the timber or eliminates them altogether. For example, you can remove a wood knot when you cut the veneers to size. Or, if that is not possible, a single wood knot is spread out over different areas of the veneer taking away any of its negative effects.
As a result LVL products are incredibly uniform. The extra strength makes them comparable to solid timber, concrete and steel. LVLs, being engineered wood products, means they are much less prone to warping and shrinking. Which in turn, means you get consistently straighter timber. Another aspect that sets LVLs apart is that they can be up to 30% lighter than the equivalent size hardwood.
Being a manufactured timber product means that LVLs are hugely versatile. They can be used in place of almost any regular timber in most situations. This is made possible due to the ability for LVLs to be made in whatever size you need and a huge range of shapes. The added strength of LVLs means a single length can span long distances and support heavier loads.
Timber has been described as the 'Ultimate Renewable' by the Australian Government and for good reason. As long as our timber industry is well managed this wonderful resource will remain plentiful and the top choice for sustainable building materials. Compared to other materials such as concrete and steel, the amount of energy that goes into producing timber products from start to finish is much less. The manufacturing process ensures the timber resources are used to their full potential and the least amount is wasted. LVLs are also highly cost-effective, they are able to deliver better performance, versatility and variety for less than other options. Being able to source LVLs at whatever size you need means less time cutting and joining smaller lengths of regular timber which also means less time spent on a job.
Advantage of WENWEI structural LVL
1. Small logs can be made into large dimension LVL products.
2. Long lengths of LVL are available up to 12m
3. The wood resource can be optimised by grading and selecting veneer for different parts of an LVL cross section and making a range of products with different properties.
4. Structural properties of LVL are very uniform because the randomised layers of thin veneers are pre-graded for stiffness (coefficient of variation for modulus of elasticity less than 5%).
5. LVL members have high strength because of the low variability and randomised wood properties in thin layers.
6. LVL can be cut and machined with normal woodworking tools.
7. LVL is often used to complement the use of sawn timber in domestic construction.

Application of WENWEI structural LVL
LVL is particularly well suited to the following applications
Rafters and joists
Lintels, beams and framing members
Truss chords
Portal frames
I-beams
Box-beams
Scaffold planks
Formwork
Panels of LVL are cut into structural members which have high strength and stiffness.
LVL is suited to structural applications such as beams, rafters and columns in a wide range of buildings including houses, commercial, industrial and rural structures. Some special LVL has a small number of veneers laid perpendicularly (cross banded).
In commercial or industrial structures it is often used as a wood-based alternative to structural steel or reinforced concrete.
