Description
FORMWORK LVL – Key English-Language Parameters (2025 production)
1. Formwork LVL Targeted density
• Formwork LVLMean: 580 kg/m³ (radiata-pine core, 12 % MC)
• Formwork LVL Range allowed: 520–630 kg/m³
2.FORMWORK LVL Moisture content at factory dispatch
• Formwork LVL 8 %–14 % (AS/NZS 4357 & EN 14279)
• Formwork LVL Surface-painted red edge keeps MC drift < 2 % during a 3-month formwork cycle
3. FORMWORK LVL Dimensional stock sizes (most common)
• Formwork LVL 95 × 47 mm, 150 × 77 mm, 170 × 36 mm, 200 × 36 mm, 240 × 45 mm
• Formwork LVL Lengths 2.4 m–6.0 m in 0.6 m increments; specials to 12 m on request
• Formwork LVL Thickness / width tolerance: ±1 mm (sanded) or ±2 mm (unsanded)
4. FORMWORK LVL Glue & durability
• Formwork LVL Phenolic WBP A-bond, EN 314-2 / AS 2754.1
•Formwork LVL Optional H2 (LOSP) or H3 (ACQ) treatment; red edge paint gives extra moisture & UV shield
5.FORMWORK LVL Mechanical grades typically supplied for formwork
•Formwork LVL F11-E11 (E ≈ 11 GPa, fb ≈ 48 MPa)
• Formwork LVL F14-E12.5 (E ≈ 12.5 GPa, fb ≈ 55 MPa)
• Formwork LVL F17-E14 (E ≈ 14 GPa, fb ≈ 63 MPa)
Safety factor for repeated reuse: 0.9 (duration-of-load k3 = 0.65)
6. FORMWORK LVL Re-use & cycle life
•Formwork LVL 10–20 pours when used as edge-board with 25 kN/m² concrete pressure; 30+ cycles achievable as joist/bearer at ≤ 6 kN/m² provided striking & storage follow supplier guidelines
7. FORMWORK LVL Straightness & machining
• Formwork LVL Bow ≤ 1.5 mm/m; twist ≤ 2 mm/m
• Formwork LVL Arrised edges 2 × 2 mm to reduce chipping during striking
• Formwork LVL Each piece hot-branded with grade, mill ID, month/year for traceability
8.FORMWORK LVL Packaging / logistics
• Formwork LVL 20′ GP: ≈ 22 m³ (8 pallet packs)
•Formwork LVL 40′ HQ: ≈ 45 m³ (16–18 packs)
• Formwork LVL Weight per lin-m (170 × 36 mm): ≈ 3.6 kg
9.FORMWORK LVL Storage on site
• Formwork LVL Stack on level bearers ≤ 1.8 m centres, clear of ground; cover top only to allow ventilation; cut ends re-seal within 4 h to maintain MC and prevent swelling
10.FORMWORK LVL Standards compliance
• Formwork LVL AS/NZS 4357 (structural LVL)
•Formwork LVL BSI Benchmark or Engineered Wood Products of Australia (EWPAA) third-party audit; CE optiona
