Product details
Premium 3 Ply Shuttering Yellow Board
3-Layer Concrete Casting Plywood | High Strength & Waterproof Construction Formwork

1. Product Introduction

3-layer concrete casting plywood is a high-performance formwork specially designed for concrete pouring projects. Adopting a three-layer symmetrical cross-glued structure with pine and spruce wood veneers, combined with high-temperature high-pressure phenolic resin glue and double-sided waterproof film, it features high rigidity, low deformation, easy demolding and reusable performance. Ideal for high-standard construction projects such as high-rise buildings, factories, bridges and hydraulic engineering.

2. Core Advantages

Stable 3-Layer Symmetrical Structure

The symmetrical cross-laminated design balances internal stress effectively, effectively avoiding warping, bulging and cracking under pressure or humid conditions. It provides ultra-flat concrete surface without secondary plastering, greatly reducing rework. 

High-Density Solid Wood Base

Made of premium pine and spruce materials with no hollow cores, no broken pieces and no wormholes. The tight and uniform texture ensures high hardness and impact resistance, resisting damage during hoisting, treading and concrete vibrating, meeting heavy-duty engineering requirements.

Waterproof & Anti-Corrosion Film Surface

Double-sided high-density waterproof resin film features compact and smooth surface with excellent waterproof, moisture-proof and acid-base resistant performance. It will not absorb water, expand or peel in rainy, wet and underground construction environments, effectively preventing concrete sanding, pitting and bonding problems.

High-Strength Glue Bonding

With industrial waterproof phenolic resin glue, the tight interlayer bonding avoids delamination and glue failure. It is heat-resistant and water-soak resistant, maintaining stable structure after repeated use.

Easy Demolding

The low-adhesion smooth film prevents cement sticking and hanging. No extra release agent is needed for quick and clean demolding. It delivers mirror-level smooth concrete surface with neat lines, saving polishing and repairing cost.

3. Application Scenarios

  • Building Construction: High-rise buildings, office buildings, factories, wall, beam and floor pouring
  • Bridge & Road Engineering: Bridge pier, guardrail, culvert and tunnel concrete forming
  • Municipal & Hydraulic Engineering: River slope, reservoir, dam, underground pipe gallery and sewage treatment projects
