The Timber and Plywood Behind Quality Concrete
A timber formwork system has two main parts. The form face — the surface the concrete is cast against — is typically formply: structural plywood finished with a high-density phenolic film that gives a smooth, water-resistant face, releases the set concrete cleanly and produces a quality off-form finish. Behind the face sit the bearers and joists that carry the load of the wet concrete; these need to be stiff and straight to hold accurate levels and resist deflection, which is exactly what engineered Formwork LVL provides. Choosing the right products comes down to the loads, the re-use you need and the concrete finish you are after. Higher formply stress grades (F22, F27) and stiffer bearers carry more load and stand up to heavier, more repeated use, while the surface class of the formply governs the off-form finish under AS 3610. JVS Timber stocks the full range so you can build a formwork package matched to your job, and our team can help you specify it.

Standards, Grades and Off-Form Finish
Formply is made to AS 6669 (Plywood — Formwork) and is typically described by three things: its surface class, its stress grade and its bond type — for example, 'Class 2 F17 A-Bond'. The surface class relates to the off-form concrete finish achievable under AS 3610, the stress grade (the 'F' number) is the panel’s bending strength in megapascals, and an A-bond is the durable, exterior phenolic bond suited to formwork. Our Formwork LVL bearers and joists are made to AS/NZS 4357 and carry an H2S glueline termite treatment. Higher F-grades are stronger and stiffer, allowing greater loads or wider support spacing, while a higher surface class gives a finer off-form finish. The right combination depends on the loads, the re-use required and the concrete finish specified, so the panel grade, thickness and support spacing should always follow the formwork design. Our team can help you match grade, class and supporting structure to your job.

Formwork products are designed to be re-used, and getting many pours from each sheet and bearer is both economical and sustainable. JVS Timber supplies formply made to AS 6669 and LVL to AS/NZS 4357, compliant with Australian industry standards. Caring for formwork so it lasts more cycles — sealing edges, cleaning down, protecting from damage and storing well — is the most sustainable way to use it.

The 'F' number is the plywood’s bending stress grade in megapascals — the higher the number, the stronger and stiffer the panel. F17 is the general-purpose grade, F22 is higher-strength for heavier or more repeated use such as system formwork, and F27 is a premium full-hardwood grade for the heaviest construction and mining formwork.
