Polyester Faced Plywood Polyester Plywood is a work of art, from the mixture of compounds to the end product. It is all painstakingly created, step by step to give you a perfect product. Each piece of polyester plywood goes through a process of application of polyester resin, rolling, spreading of the polyester resin, curing and finally cutting. Polyester coating makes …

Formply or Film-Face Plywood? – The Facts Explained!Formply is the well-known plywood specifically engineered for the Concrete Formwork Industry. Certified to specific stress-grades, Formply is typically available in various strength ratings from F11 thru to F27. Formply sheets are 17.5mm thick (historically the most popular choice), plus 12mm and 25mm are now also available in 1800 X 1200mm and 2400 …

The strength of Australian timber is described in terms of “stress grades“. Stress Grading is a way of classifying timber, either visually or by mechanical means to indicate the basic properties to be used for structural design purposes. The stress grade is designated in a form such as “F14”, which indicates that the timber’s working stress in bending is approximately 14 MPA (Megapascals). The timber stress …

Timber Grading – Strength Do you know how strong your timber is? A timber’s strength in a construction context refers to the ability of a piece of timber to maintain stress (force) without ‘failure’. ‘Failure’ in this sense doesn’t necessarily mean breaking, but is more about bending strength, ie: how much downward force can be applied without the member deflecting …

Formwork and shuttering are both common terms in the concrete construction industry. Sometimes, these terms are used interchangeably. Formwork is the overarching term that’s used to describe the forming process. Shuttering is defined as the temporary moulds that are used to hold the wet concrete in place until the concrete has set and cured. Projects of different sizes will often …

FORMPLY APPLICATIONSFormply combines features of architectural and structural plywood to create a strong and modern product. Its primary use is in concrete formwork. The panels hold the concrete in a mould until it sets. F17 use is widespread on beams, bridges, large deck forms, and other civil engineering projects. It has even been used to build a python enclosure! Figure …

IS FORMPLY WATERPROOF? Formply is water-resistant but not entirely waterproof. Sheets are designed to withstand moisture on-site through their high-density overlay. The film on top is waterproof, while the edges are sealed to ensure no moisture is absorbed. Concreters can re-use sheets on many sites thanks to quality materials and manufacturing

FORMPLY VS MARINE PLYWOOD Workers would coat marine plywood sheets in oil for a smooth finish before formply. F17 expands upon marine plywood, ideal for use in areas of constant contact with moisture. The outer face is waterproof, allowing for easy separation from curing concrete. Formply is attractive with a variety of colour available for home furnishing. Formply exceeds marine plywood despite not technically meeting its …

MARINE VS REGULAR PLYWOOD Not all structural plywood is labelled as marine due to the strict criteria it must fulfil. Voids cannot be present in the inner veneer layers due to their delaminating effect. The risk of it occurring rises when there is a build-up of moisture. Manufacturing must also use waterproof glue. Finally, marine plywood requires a higher grade face veneer than …
