Should GCC formwork plywood be EN 636-3 or EN 636-2?
For GCC sites that store panels in direct sun or plan more than about ten pours per sheet, specify EN 636-3 with a phenolic Class 3 glue line (Pro Form, Pro Form Lite, or HDO). EN 636-2 core-MUF panels still fit shaded, low-cycle finishing work. Heat above about 40°C softens MUF bond shear over the programme, so the climate answer belongs on the RFQ before price.
Is Form Extra a Class 3 panel for Gulf projects?
No. Form Extra stays in the EN 636-2 envelope with Superior Glue MUF. Phenolic Class 3 covers Pro Form, Pro Form Lite, and the HDO range only. Extra reuse on Form Extra comes from glue chemistry under the same phenolic face film as Form Basic, not from a Class 3 boil-test bond.
How many reuses can film-faced plywood take in GCC heat?
Reuse is always an up-to-N band, not a guarantee. Eco Form Plus is up to 8, Form Basic up to 10, Form Extra up to 15, Pro Form Lite up to 15, and Pro Form or HDO Premium up to 20 when edge seal, release agent, and shade keep pace. Dust and uncovered stacks spend that life faster than the grade table admits.
Which sheet sizes are common on UAE and Saudi formwork?
1220 × 2440 mm (4 × 8 ft) remains the workhorse on many PERI and DOKA decks and on loose-panel wall and column work. 1250 × 2500 mm shows up more on European-engineered megaprojects where cut waste has to stay low. Standard thicknesses are 18 mm for walls and columns, 12 mm for light edges, and 21 mm for deep lifts.
Do SABER or ESMA change the plywood grade I should buy?
SABER in Saudi Arabia and ESMA / MOIAT in the UAE are conformity and registration gates for customs release. They are not quality grades by themselves. You still write BS EN 636 class, BS EN 314-1 Class 3 bond where required, face film weight, and edge seal into the tender, then clear SABER or ESMA paperwork before the container loads.
How long does Vietnam-to-GCC ocean transit usually take?
Buyers typically plan about 15–22 days ocean into Jebel Ali, with similar multi-week windows into Dammam, Jeddah, Hamad, Sohar, Salalah, and Shuwaikh. Factory production after order confirmation adds more time, so a first container is usually a multi-week commitment from RFQ to gate-in. Those figures are planning ranges, not freight quotes.
