Formwork Plywood

F17 Formply

F17 Formply is a high-strength structural plywood with high-grade hardwood or birch core material and a water-resistant phenolic high-density membrane (HDO) on the surface. It meets the Australian AS6669 and F17 bending strength standards (≥17MPa). It is suitable for high-load environments such as concrete formwork, rail vehicle chassis and building support structures.

NOTE: All products can be custom made in size and finish for your specific application.

Product Features

  • High structural strength

    F17 grade guarantees ≥17MPa bending strength and strong bearing capacity.

  • Smooth and durable

    High-density membrane surface (HDO) is waterproof and does not expand, and the concrete surface is flat and high-quality.

  • Environmental resistance

    wear-resistant, alkali-resistant, chemical-resistant, high and low temperature (–40℃ to +50℃), long service life.

  • Stable structure

    multi-layer cross-gluing, anti-cracking and anti-warping

  • Waterproof sealing

    water-based sealing paint is applied to the four sides of the edge in the factory to reduce moisture intrusion.

  • Reusable

    The surface is wear-resistant and peeling-resistant, and can be re-sealed after cutting for continued use.

Applications

  • Concrete pouring formwork

    building columns and walls, beams and slabs, structural support systems

  • Track and vehicle components

    carriage floors, sleeper bottom plates

  • Temporary support structures

    scaffolding platforms, floor paving, roof support plates

  • Multiple reuse projects

    high turnover construction sites, rental formwork, etc.
