Shuttering plywood (also called film-faced plywood, concrete formwork plywood, or form ply) is a specialized type of structural plywood engineered specifically for creating molds ("shutters" or "forms") to hold wet concrete in place during construction until it hardens.
| Parameter | Specification |
|---|---|
| Core Material | Hardwood (Eucalyptus/Poplar/Birch) |
| Surface Coating | Phenolic Film (Brown/Black) |
| Glue Type | WBP (Water Boil Proof) |
| Density | 680-720 kg/m³ |
| Moisture Content | 8-12% |
| Flexural Strength | ≥30 MPa (Lengthwise) |
| Formwork Cycles | 15-25 times |
Key Features
Waterproof Film Coating
Faces are laminated with phenolic resin-impregnated film (brown/black).
Creates a non-stick barrier against wet concrete.
Resists water, chemicals, and abrasion during pouring/curing.
High-Strength Core
Made of wood veneers (e.g., poplar, birch, eucalyptus) bonded with WBP glue ("Weather & Boil Proof").
Maintains stability under heavy wet concrete pressure.
Engineered Thickness Tolerance
Thickness (e.g., 18mm ±0.5mm) is tightly controlled to prevent concrete bulging or misalignment.
Reusability
Can be reused 15–30+ times (vs. 2–5 uses for regular plywood), reducing project costs.
Core Purpose
To serve as a reusable, high-strength mold for pouring concrete structures (walls, columns, slabs, etc.), ensuring:
- Smooth concrete surface finish.
- Dimensional accuracy of the structure.
- Efficient de-molding (easy release after curing).
Why Use Shuttering Plywood (vs. Regular Plywood)?
| Aspect | Shuttering Plywood | Regular Plywood |
|---|---|---|
| Surface Finish | Ultra-smooth concrete surface | Rough, sticky concrete finish |
| Water Resistance | Fully waterproof (film + WBP) | Swells/delaminates with moisture |
| Durability | Withstands repeated concrete loads | Warps/cracks under pressure |
| Cost Efficiency | Lower cost-per-use over 15+ cycles | High replacement frequency |
Structure
Veneers: Thin sheets of wood are peeled or sliced from logs.
Cross-Graining: Adjacent veneers are layered with their wood grain running perpendicular (at 90-degree angles) to each other.
Bonding: The layers are glued together under heat and high pressure.
Applications
High-rise building concrete formwork
Bridge piers & infrastructure projects
Foundation walls & columns
Precast concrete manufacturing
Industrial flooring systems
