Every panel we press,
on one page.
Size, thickness, face, glue, core, tolerance, loading quantity and the report behind each figure — on one page, so a buyer can check the numbers against a sample instead of taking them from a brochure.
Product matrix
| Line | Thickness | Face | Glue | Reuse | Report |
| Red board | 12/15/18/20 mm | Red-dyed film, smooth | WBP melamine | Fewer pours | JC21-WT0110 |
| Black film-faced | 12/15/18/20 mm | 60 g/m² black phenolic | WBP phenolic, 72 h boil | 8–12 cycles | JC21-WT0099 |
| Shuttering | 12/15/18/20 mm | 60 g/m² black phenolic | WBP phenolic, 72 h boil | 8–12 cycles | JC21-WT0099 |
| Formwork | 12/15/18/20 mm | 60 g/m² black phenolic | WBP phenolic, 72 h boil | 8–12 cycles | JC21-WT0099 |
Shuttering and formwork are the same panel as the black film-faced line, sold under the name each market uses. One product, three entries, because buyers search in three words.

Loading per 40HQ, by panel and by cubic metre
| Thickness | Panels per 40HQ | Volume of panels | Indicative weight |
| 12 mm | 1,400 | ≈ 50.0 m³ | ≈ 26.6 t |
| 15 mm | 1,200 | ≈ 53.6 m³ | ≈ 28.5 t |
| 18 mm | 930–960 | ≈ 49.8–51.4 m³ | ≈ 27.6–28.5 t |
| 20 mm | Confirmed per order | ≈ 0.0595 m³ per panel | Within payload |
One 2440 × 1220 mm panel covers 2.977 m² of face, so its volume is 0.0357 m³ at 12 mm, 0.0447 m³ at 15 mm, 0.0536 m³ at 18 mm and 0.0595 m³ at 20 mm. A 40HQ holds roughly 76 m³ of space, but it is filled by weight long before it is filled by cube — which is why the loading quantity, not the volume, is the figure we quote and confirm on the proforma invoice. Maximum payload about 28.5 t; the tonnages above are indicative at a panel density of about 540–560 kg/m³, and actual weight moves with core density.
Three things the table does not say
These are material values, not design values
A formwork designer still has to apply a safety factor, a moisture-cycling allowance and a deflection check against the concrete pressure on the drawing. The report says what the panel measured in a laboratory; it does not certify a formwork design.
Combi core means three species, mixed
Eucalyptus, pine and fir veneers in one panel, glue on every ply. It is not a single-species core and it is never written as one. A buyer comparing this against a poplar-core offer is comparing two declared mixes, which is the only comparison that means anything.
Two things are not published
A price, because it moves per order — the pricing page explains the variables. And a certificate we do not hold: FSC, CE and ISO are not in hand yet and the quality page states that plainly.
Three practical ones
What does ±0.5 mm mean when panels are laid side by side?
It means any two panels from a batch can differ by up to half a millimetre at the edge, which is what the joint filler and the formwork clamp absorb. Where a perfectly flush joint matters, check the thickness of the batch with a calliper before the first pour rather than after.
Can you press sizes other than 2440 × 1220 mm?
The line runs 2440 × 1220 mm. Any other size has to be confirmed against the press and trimming setup before we quote it — we do not promise a size we cannot press, and we will say so at inquiry rather than after deposit.
Is moisture content checked on every batch?
Yes. Thickness, moisture and bonding strength are checked batch by batch; the 9 % figure above is the value on the 18 mm sample sent to the laboratory.
