Our film-faced shuttering plywood is designed to deliver exceptional durability, strength, and reusability, making it ideal for high-performance construction applications. The key features that enhance its quality include:
1. High-Quality Film Coating (120+ GSM)
Our plywood is coated with a high-density waterproof film (120+ GSM or more), which provides a smooth, non-stick surface that prevents concrete adhesion. This results in better finishing and easier demolding after curing.
2. High Repetition Usage (20+ Times)
Engineered for multiple uses, our shuttering plywood maintains its strength and shape over 20+ repetitions, ensuring long-lasting performance and cost-effectiveness.
3. Water and Weather Resistance
The high-quality phenolic film and strong bonding adhesives make our plywood highly resistant to water, moisture, and extreme weather conditions, preventing warping and swelling.
4. Strong Core Construction
Made from premium-grade hardwood with phenol-formaldehyde (PF) bonding, our plywood offers exceptional load-bearing capacity and resistance to bending, cracking, and deformation.
5. High Load-Bearing Capacity
Designed to withstand heavy concrete pressure, our film-faced plywood provides strong structural stability, ensuring safety and efficiency in construction projects.
6. Smooth and Uniform Surface
The superior-quality film facing ensures a uniform, glossy surface, reducing the need for additional finishing work and enhancing the quality of the final concrete structure.
7. Edge Protection for Longevity
All edges are sealed with a water-resistant coating, preventing moisture absorption and extending the lifespan of the plywood.
Our film-faced shuttering plywood is the perfect solution for builders and contractors looking for high-quality, long-lasting, and cost-effective formwork solutions.
