Application Guide – Choosing the Right LVL Section
| Application | Recommended Section | Why |
|---|---|---|
| Formwork Bearers (Primary Beams) | 240x45mm, 290x45mm, 400x45mm | High load capacity, minimal deflection under concrete pressure |
| Formwork Joists / Purlins | 90x45mm, 140x45mm, 190x45mm | Lightweight, straight, easy to handle and install |
| Formwork Walers | 240x45mm, 290x45mm | Consistent flatness, excellent reuse rate |
| Structural Roof Beams | 240x45mm, 290x45mm | Long-span capability, predictable performance |
| Floor Joists & Lintels | 140x45mm, 190x45mm | High strength-to-weight ratio, no twisting or cupping |
| Heavy Supports & Soldiers | 90x45mm, 140x45mm | High compression strength, impact resistant |
Material Advantage – Why Full Larch & High Density Matter
| Feature | Benefit |
|---|---|
| Full Larch Construction | Naturally dense, strong, and durable. Provides higher mechanical properties than mixed species. |
| 750 kg/m³ Density | Exceeds typical LVL density (usually 600–650 kg/m³). Translates to higher load capacity and stiffness. |
| Dynea Phenolic Adhesive | Global leader in wood adhesives. Ensures WBP-grade waterproof bond, resistant to delamination even under wet site conditions. |

FAQ – 12m LVL Beams
Q: Is this LVL beam suitable for use in wet conditions?
A: Yes. Our LVL uses Dynea phenolic adhesive, which is WBP (Water and Boil Proof) grade. It is suitable for the typical wet exposure on formwork sites. However, we recommend proper site storage and edge sealing for maximum reuse.
Q: What is the maximum length you can produce?
A: We can produce LVL beams up to 12 metres in one piece. Longer lengths can be achieved through finger-jointing.
Q: Do you provide test reports for AS/NZS 4357 compliance?
A: Absolutely. We provide full AS/NZS 4357.0 test reports from our ISO 17025-accredited laboratory with every shipment.
Q: Can I mix different sections in one container?
A: Yes. We offer mixed container solutions – you can combine different lengths, sections, and grades in one 20GP or 40HQ container to optimize your inventory.
Q: What is the lead time for 12m beams?
A: Typically 7–14 days after deposit confirmation, depending on the specific sections and volume.
