Formply
Formply™

IPL Formply is manufactured for use in the concrete forming industry to provide strong, stiff, lightweight support for the forming of concrete structures. It can also be used where any other hard wearing surface is required. IPL Formply is the only manufactured concrete forming plywood made in New Zealand.

At a glance.

Formply™
  • Used successfully in Asia, Australia, the Pacific Islands and New Zealand for 30 years
  • Overlaid with high quality, heavy duty phenolic resin impregnated papers which provide a hard wearing surface.
  • Suitable for concrete shuttering and also for truck and ute decks, shelves and any wooden surface which is subject to high wear.
  • Superior quality and surface which transmits into the finish of the concrete.
  • Phenolic overlay paper protects the surface veneer from excessive moisture uptake which assists to minimize hydration staining and grain raising.
  • Resists dilute acids and alkalines which increases the number of uses that is obtained when used with concrete.

Usage and Maintenance

●     Place long edge of sheets across the supports.
●     Allow 2-3mm expansion gap on all sheet edges and, if required, use        some form of elastic sealer to fill the gap —the gap may have to be        widened to allow for the gap filler.
●     When nailing or screwing the sheets, it is essential to fix to avoid        movement. When countersinking the fixings through the overlay        paper it will be necessary to fill these with epoxy filler and smooth        off to give good finish and limit moisture uptake.
●    To avoid staining from fasteners use hot-dipped galvanised,       stainless or alloy fasteners.
●    Cut edges should be resealed using acrylic paint which helps keep       moisture out and minimises distortion that can be caused by       expansion around sheet perimeters. The factory’s cut edges are       coated with a water-repellent coating. The veneers are bonded with       marine type glue, which ensures they will not separate under wet       conditions.
●    Use release agent before use andre use to ensure clean release       from concrete and to minimise hydration staining and grain raising.
●    Take care to avoid vibrator contact as much as possible to keep       face intact and in so doing extend the life, to give repeat service.
●    When storing sheets, where possible, lay flat with support of       bearers.

Design and Installation

Spacings for framing supports depend on the properties that pertain to the sheets construction and direction of the face veneer (table1). These values are used in conjunction with standard engineering standards to design the form to withstand the pressure developed by the wet concrete and how much deflection is allowable.
The actual thicknesses of our sheets are 12.5mm and 17.5mm but the 12mm and 17mm values in the tables can be attributed to our sheets.

Quality Assurance

IPL Formply is made to the highest qualitylevels based on the requirements of the Australian/ New Zealand standard 2269and AS6669 in conjunction with the Engineered Wood Products Association ofAustralasia.
