Core Definition：A high-performance structural formwork beam for construction, with a standard height of 200mm (the origin of "H20"), composed of solid wood/LVL flanges (top/bottom) and plywood/LVL web (middle), bonded by high-strength adhesive. It’s the most widely used timber I-beam in global construction formwork, suitable for various concrete formwork support systems.
| Parameter | Standard Value | Optional Value |
|---|---|---|
| Height | 200mm | - |
| Flange Width | 60mm | 50mm/70mm |
| Web Thickness | 27mm | 30mm (reinforced) |
| Length | 2.0m-6.0m | Custom 1.5m/7.0m (per request) |
| Flange Material | LVL (Laminated Veneer Lumber) | Solid pine/spruce |
| Web Adhesive | WBP Phenolic Glue (D4 grade) | - (mandatory for construction) |
| Bending Strength | ≥45 N/mm² | - |
| Density | 600-650 kg/m³ | - |
High Strength-to-Weight Ratio：Light weight (easier for on-site handling) with excellent load-bearing capacity, reduces labor and construction time.
Stable Performance：Anti-warping, anti-deformation, uniform mechanical properties (no obvious wood defects).
Water/Moisture Resistant：WBP phenolic glue and surface treatment adapt to wet construction site environments.
High Reusability：Main configurations can be reused 10-20 times, lower long-term construction costs.
Easy Assembly：Compatible with standard formwork accessories (props, connectors, brackets), flexible for various formwork systems.
Eco-friendly：Made of renewable wood materials, compliant with EU/US environmental standards.
Concrete formwork support for residential buildings, high-rises, factories
Slab, beam, column formwork in municipal projects, bridges, basements
Temporary support structures for prefabricated construction, large-span projects
Custom formwork systems for industrial and commercial construction
Standard Version：LVL flanges + 3-ply WBP plywood web (27mm) - 90% of overseas orders, high cost-performance, industry universal standard.
High-End Version：LVL flanges + LVL web (27/30mm) - for heavy load/long-term use, recommended for professional contractors.
Reinforced Version：LVL flanges + 5/7-ply WBP plywood web (30mm) - balanced performance & cost, for medium-heavy load projects.
❗ Not Recommended for Overseas Formal Orders：Flanges + Particle board web (only for light load/dry temporary projects, low market demand).
Compliant with EN 13377 (European standard) and ASTM (US standard) - meet global construction material certification requirements.
Customizable length/accessories (e.g., pre-drilled holes, metal end caps) - support OEM/ODM for clients.
One-stop matching with formwork accessories (props, U-heads, clamps) - save clients’ procurement time.
