Product Details ofShuttering Plywood
Dadi Wood film faced shuttering plywood is manufactured from imported hardwood logs, surfaced with high-density phenolic or melamine resin film. The panel consists of multiple layers of hardwood veneer (poplar, eucalyptus, or poplar-eucalyptus composite), bonded with waterproof adhesives including phenolic, WBP, or melamine glue.
Formwork provides temporary structural support to maintain concrete shape and dimensions during curing. After full hardening, the plywood formwork can be easily stripped, delivering a smooth concrete finish that greatly reduces secondary plastering work.

Product Performance Advantages
Corrosion Resistance
Resistant to alkali and cement hydration corrosion; phenolic film withstands pH 10–13 alkaline environments. Panel surface resists powdering and delamination, greatly extending service life.
01
Easy Demolding
Low friction coefficient on film surface, demolding force < 0.03 MPa. Smooth stripping without concrete adhesion ensures intact surface finish and improves construction efficiency by over 30%.
02
35 Reuses
Surface abrasion resistance ≥ 500 revolutions, core static bending strength ≥ 28 MPa. Stable reusability of 30–35 times under normal construction, significantly reducing unit cost.
03
Smooth Surface
Surface flatness tolerance ≤ 0.3 mm/m, achieves fair-faced concrete effect without secondary plastering or leveling.
04
High Strength & Durability
Vertical bearing capacity ≥ 25 kN/m², modulus of elasticity ≥ 4500 MPa. Deformation < 1.5 mm under high pouring pressure, no bulging or delamination.
05
Product Application
Here's how shuttering plywood is applied in practical construction environments:
Large Slabs and Floor Plates: Used under cast-in-place concrete to form flat, level surfaces.
Column and Beam Molds: It forms precise frameworks for load-bearing vertical and horizontal elements.
Foundation Walls: Shuttering plywood ensures accurate shaping and alignment of concrete walls.
Infrastructure Projects: Bridges, tunnels, and highways benefit from its strength and reusability in large-scale formwork.
FAQ
Q: What is the best thickness for shuttering plywood?
A: The recommended thickness is 12mm or higher for optimal load-bearing capacity.
Q: What is the difference between shuttering plywood and regular plywood?
A: Standard plywood is not built to handle the pressure or alkalinity of curing concrete. Shuttering plywood has a moisture-proof surface (phenolic or melamine film) and a heavy-duty core made of hardwood or engineered veneers that can bear significant weight without warping.
Q: Is shuttering plywood water-resistant?
A: Yes, BWP and film-faced plywood are designed to resist water and weather conditions, making them ideal for outdoor use.
