Is formply the same as film-faced plywood?
All formply is film-faced plywood, but not every film-faced sheet is formply. Formply also carries an Australian structural grade, typically F17 under AS/NZS 2269, and is made or branded for formwork under AS/NZS 6669. An imported mill sheet can use the same phenolic face film while documenting its bond through an EN 636 class instead, so the real split is the grading file rather than the overlay.
Can imported film-faced plywood be used instead of formply?
Yes, when the imported sheet meets the F17 grade or EN 636 class the engineer named and the project paperwork backs it up. Many Australian contractors already run Vietnam film-faced panels as formply. Ask for the mill test report and the glue class, plus chain of custody where the job requires it and biosecurity documents for the packaging.
How many times can formply be reused?
Reuse depends on grade and site care, so it is written as up to N rather than promised. On the Vinawood film-faced ladder Eco Form Plus is rated up to 8 reuses, Form Basic up to 10, Form Extra and Pro Form Lite up to 15, and Pro Form up to 20. Form Extra gets its extra cycles from a tougher Superior Glue MUF line and stays EN 636-2, not Class 3. Sealed edges, even release agent and careful stripping decide whether a sheet gets near its ceiling.
What thickness formply is used in Australia?
Most Australian slab and wall work uses 17 mm or 18 mm sheets, which fit common formwork frames when the hole pattern matches. Step up to 21 mm for wider spans. Typical sizes are 2400 × 1200 mm on local packs and 2440 × 1220 mm on many imported sheets, so put both thickness and size on the RFQ.
Does film-faced plywood hold up to rain and wet concrete?
Film-faced plywood is water-resistant, with a WBP glue line and a resin face film that handle wet concrete and site rain through a pour programme. Edges are the weak point, so seal every cut before the first pour and store packs flat, off the ground and under cover. Permanent wet duty calls for marine plywood.
Is formply stronger than film-faced plywood?
Not automatically. Formply is the sheet that carries a documented F-grade under AS/NZS 2269, while a general film-faced mill sheet is specified by its EN 636 bond class and tested bending strength. An imported sheet can serve an F17 pour when its bending and bond documents meet the project spec. Match the grading file the engineer named, because face colour says nothing about strength.
