What does F17 mean on an Australian formwork takeoff?
F17 is a stress grade tied to characteristic bending strength — roughly 17 MPa modulus of rupture under the test methods used with Australian timber design practice (AS 1720.1). It answers how strong the sheet is under load. It is not an AS 3610 off-form surface class and it is not an EN 636 moisture class, so a complete trade description usually carries more than the single word “formply.”
How do AS 3610, AS 6669, and F17 differ?
AS 3610 classifies the off-form concrete surface the specifier wants after stripping. AS 6669 (often written AS/NZS 6669) is the manufacturing standard for formwork plywood — overlay, bond type, veneer grades, tolerances, and stress grades. F17 is the stress grade used with AS 1720.1 design, not a finish label. Collapsing those three documents into one grade is how RFQs get expensive surprises.
Can Vietnamese film-faced plywood be used for concrete forming in Australia?
Yes on many private commercial programmes when the engineer accepts performance equivalence. EN 636-2 or EN 636-3 WBP film-faced panels from Vietnam are widely assessed against F17 / Type A expectations, but AS 3610 class is judged on the poured concrete, not on a mill stamp. Vinawood does not claim AS 3610 certification; for government or specification-locked jobs that require AS 6669 branding, the project engineer decides whether an EN sheet is acceptable.
Which Vinawood grades fit an Australia or New Zealand formwork RFQ?
Australian film-faced RFQs most often land on Form Basic through Pro Form. Reuse maxima under decent site care are Eco Form Plus up to 8, Form Basic up to 10, Form Extra up to 15 (Superior Glue MUF, EN 636-2, not Class 3), Pro Form Lite up to 15 (PF Class 3), and Pro Form up to 20. Class 3 phenolic means Pro Form, Pro Form Lite, HDO Standard, and HDO Premium only; HDO Basic is Class 2. Form Extra is not Class 3.
Does Vinawood publish formwork plywood prices for Australia?
No. Ocean freight, port charges, GST treatment, and domestic trucking move with the vessel and the discharge port, so landed cost belongs on a current RFQ rather than a static AUD table. Savings claims such as “20–30%” or “30–60% lower cost per pour” are not mill facts we stand behind in public copy. Lock thickness, sheet size, grade, bond class, reuse band, and discharge port in writing before arguing about freight.
What should go on an Australia formwork RFQ?
Carry five fields plus surface intent: thickness and sheet format (2440×1220 versus 2500×1250), overlay and grade, bond class (MUF EN 636-2 versus PF EN 636-3 / Class 3), expected reuse written as “up to N,” and discharge port with the documentation pack (EN DoP, mill test summary, ISPM 15 packaging). If the bid also names an AS 3610 surface class, say so in the same message so the mill matches construction instead of guessing which document the engineer meant.
