AS/NZS 4357 Structural LVL Timber is a high-strength engineered wood product made from thin layers of wood veneers bonded together with adhesive under heat and pressure. It is used in construction and building projects as a strong and durable alternative to traditional sawn lumber.

Product Description of AS/NZS 4357 Structural LVL Timber

Full Pine LVL beam, LVL framing, LVL rafters or Strand lumber/Engineered lumber/Wood beam of engineered wood for LVL moulding Structural LVL

HW structural laminated veneer lumber (LVL) which has been manufactured in accordance with AS/NZS 4357 with properties determined in accordance with AS/NZS 4063.2 and therefore complies with the requirements for structural design in accordance with AS1720.1

HW LVL terminator is available in all sizes and is part of the Carter Holt Harvey Terminator range. HW H2-S Terminator is treated against termites south of the Tropic of Capricorn. The treatment is applied to the glue-line during manufacture to achieve full termite protection to the core of the beam. No further sealing is required on cut ends, holes or notches. Other treatment levels are available from suppliers on request, but treatment is limited to above ground use. hySPAN cannot be readily treated for in ground contact applications.

HW LVL is manufactured using an ‘A’ Bond with less than 0.5mg/l Formaldehyde (equivalent to E0) emissions from the final product.

For quality assurance the HW range is manufactured with independent audit processes and product certification. Carter Holt Harvey ensures that its wood is legally sourced from managed forests and offer FSC ‘Chain of Custody’ certified upon request.

HW LVL is produced with a structural grade face and is not generally used in appearance applications and at the time of dispatch from the manufacturing site has a moisture content of between 8-15%.

Advantage of AS/NZS 4357 Structural LVL Timber

1. High strength: Structural LVL Timber is a strong and durable material that can withstand heavy loads and stresses.
2. Consistent quality: Unlike traditional sawn lumber, Structural LVL Timber has a uniform and consistent size, shape, and strength, making it easy to work with and ensuring predictable performance in load-bearing applications.
3. Versatile: Structural LVL Timber can be easily cut, drilled, and shaped to suit a wide range of structural applications, including beams, headers, columns, and joists.
4. Environmentally friendly: Structural LVL Timber is made from sustainably harvested wood and can be recycled or repurposed at the end of its life, making it a more environmentally friendly choice than many other building materials.
5. Fire-resistant: Structural LVL Timber is typically more fire-resistant than traditional sawn lumber, which can help to improve the safety of a building in the event of a fire.
6. Wide range of sizes: Structural LVL Timber is available in a range of standard sizes and thicknesses to suit different structural applications, and custom sizes may also be available from some manufacturers.
7. Easy installation: Structural LVL Timber is easy to install and requires minimal maintenance, which can save time and money in construction projects.

          

 

Application of AS/NZS 4357 Structural LVL Timber

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.

FAQ

Q: What is the difference between LVL and traditional sawn lumber?

A: LVL is an engineered wood product made from thin layers of wood veneers bonded together with an adhesive under heat and pressure. Traditional sawn lumber is cut directly from logs and is not bonded in the same way. LVL is stronger, more consistent in size and shape, and more environmentally friendly than traditional sawn lumber.

Q: What applications is AS/NZS 4357 Structural LVL Timber suitable for?

A: AS/NZS 4357 Structural LVL Timber can be used in a wide range of applications, including beams, headers, columns, and joists. It is commonly used in residential and commercial construction projects as a strong and durable alternative to traditional sawn lumber.

Q: How is AS/NZS 4357 Structural LVL Timber manufactured?

A: AS/NZS 4357 Structural LVL Timber is manufactured by bonding thin layers of wood veneers together with an adhesive under heat and pressure. The resulting product is stronger and more uniform in size and shape than traditional sawn lumber.

Q: Is AS/NZS 4357 Structural LVL Timber environmentally friendly?

A: Yes, AS/NZS 4357 Structural LVL Timber is made from sustainably harvested wood and can be recycled or repurposed at the end of its life, making it a more environmentally friendly choice than many other building materials.

Q: What sizes and thicknesses is AS/NZS 4357 Structural LVL Timber available in?

A: AS/NZS 4357 Structural LVL Timber is available in a range of standard sizes and thicknesses to suit different structural applications, and custom sizes may also be available from some manufacturers.
