Shuttering Plywood: High-Quality Formwork Solutions for Construction Projects
Shuttering plywood sheets provide the essential formwork surface for vertical concrete pours, combining lightweight handling with high pressure resistance. Avanza Steel’s plywood is a film-faced, phenolic-coated panel designed for up to 15 reuse cycles, ensuring consistent surface quality, rapid assembly, and long-term cost efficiency.
What Is Shuttering Plywood?
Shuttering plywood (also called film-faced or phenolic plywood) is a multi-layer panel bonded with waterproof glue and coated on both faces with a phenolic film. This creates an impervious, smooth surface that delivers near-perfect concrete finishes and resists moisture, abrasion, and chemical attack.
Core Advantages:
-
Exceptional Durability: Up to 15 formwork cycles with proper handling.
-
Waterproof & Chemical-Resistant: Phenolic film prevents delamination and swelling.
-
Smooth Surface Finish: Reduces patchwork and remedial plastering post-strip.
Lightweight & Modular: Standard 1.22 × 2.44 m size for quick positioning and minimal waste.

Technical Specifications
Applications & Use Cases
-
Vertical Wall & Column Formwork
Film-faced sheets lock seamlessly into modular panel frames, enabling straight, curved, or tapered walls without surface imperfections.
-
Beam & Lintel Casting
High-pressure resistance ensures no bulging at corners; perfect for narrow beam shutters and concealed cast-in-place lintels.
-
Architectural Concrete Finishes
Smooth phenolic surface produces exposed-concrete textures with minimal blowholes and honeycombing—ideal for feature walls and facades.
-
Water Retaining Structures
Waterproof properties make these sheets suitable for tank walls, sewage treatment chambers, and basement foundations.
Integration with Avanza Formwork Ecosystem
Avanza Steel’s plywood sheets are designed to work in harmony with our complete shuttering system:
-
Steel Shuttering Plates & Column Forms: Combine plywood with MS plates for hybrid form faces.
-
Tie Rod & Waler Assemblies: Pre-drilled holes align with M20 tie rods and MS channel walers for consistent load distribution.
-
Adjustable Props & Base Jacks: Provide rigid support beneath plywood panels to maintain perfect alignment during pours Shuttering vs. Centerin….
-
Edge Protection & Clamping: Dedicated panel clamps lock sheets to steel frames, preventing movement and ensuring safety.
Installation & Best Practices
-
Panel Layout
-
Survey and level the shuttering frame; begin at one corner, placing boards horizontally or vertically per design.
-
Ensure film face is oriented toward the concrete for best finish.
-
-
Fixing & Alignment
-
Use M12 panel clamps or bolted couplers at 300 mm intervals along all edges.
-
Adjust frame props to achieve ± 1 mm accuracy in plumb and level.
-
-
Joint Sealing
-
For high-precision finishes, apply V-seal tape between sheets before tensioning clamps.
-
Remove tape immediately after strip to avoid film damage.
-
-
Concrete Pour
-
Monitor form pressure; do not exceed 60 kN/m² to avoid panel bulge.
-
Maintain continuous pours where possible to reduce cold joints.
-
-
Stripping & Cleaning
-
Strip once concrete reaches 70% of design strength.
-
Clean off slurry and adhering particles with low-pressure water. Avoid high-pressure jets that can lift the film.
Maintenance & Lifecycle
-
Pre-Use Inspection: Check for film tears, core delamination, and edge damage—reject any panels showing core exposure.
-
Post-Use Care: Wipe clean, allow to dry in shade, then store flat on timber battens in a covered area.
-
Re-Coating Options: For extended life beyond 15 cycles, apply a fresh phenolic varnish to high-wear areas as needed.
Sustainability Note: All end-of-life plywood is chipped and recycled, aligning with Avanza Steel’s eco-friendly commitment.
