Sheet weight matters on site for three reasons: how many people it takes to lift a panel, how much load a truck carries, and whether the board in front of you matches what was ordered. This chart gives the weights for ZIPCO® Calibrated Shuttering Plywood and the numbers you can derive from them.
The stated weights are 24 kg for a 12mm sheet and 35 kg for an 18mm sheet, both 8 × 4 ft. Other makes and cores will differ, which is why weight is a useful delivery check.
Key Takeaways
- An 8 × 4 ft ZIPCO® Calibrated Shuttering Plywood sheet weighs about 24 kg at 12mm and about 35 kg at 18mm.
- That is roughly 8 kg per m² at 12mm and 12 kg per m² at 18mm.
- A tonne carries about 41 sheets of 12mm or 28 sheets of 18mm.
- A sheet clearly lighter than the stated weight may have a thinner or less dense core.
Weight Chart (8 × 4 ft Sheet)
A standard sheet is 2440 × 1220 mm, an area of about 2.98 m².
| Thickness | Weight per sheet | Weight per m² | Sheets per tonne |
|---|---|---|---|
| 12mm | about 24 kg | about 8.1 kg | about 41 |
| 18mm | about 35 kg | about 11.8 kg | about 28 |
The per-m² and per-tonne figures are calculated from the sheet weights above and rounded. They are planning numbers, not guarantees for every batch.
Why Sheet Weight Matters
Handling and crew size
A 35 kg sheet is a two-person lift on a slab or at height. Plan panel sizes and crew accordingly, especially for upper floors.
Transport and storage
Use sheets per tonne to estimate truck loads and floor loading in the site store. Stack flat on level bearers and keep the stack covered.
Quality check at delivery
Weigh a few sheets. A sheet far below the stated weight is a reason to look closer at the edge, the thickness and the core. The 10 on-site delivery checks show the full routine.
12mm or 18mm?
Weight is one factor in choosing thickness. 12mm is lighter and quicker to handle where supports are closer. 18mm resists higher concrete pressure with wider support spacing. The 12mm vs 18mm comparison covers the structural side.
