Series Weight H20 Span Max Load Pallet
15 mm PP 28 kg 20 – 25 cm 50 kN/m² 50 pcs (156,25 m²)
18 mm PP ★ 32 kg 25 – 30 cm 60 kN/m² 40 pcs (125,00 m²)
21 mm PP 41 kg 30 – 35 cm 75 kN/m² 30 pcs (93,75 m²)

Engineering Calculation Method

Sheet Area = 1.25 m × 2.50 m = 3.125 m² (Narrow Panel: 0.625 × 2.50 m)
Net Sheets = ⌈Total Formwork Area ÷ 3.125 m²⌉
Gross Order Qty = ⌈Net Sheets × (1 + Cutting Waste %)⌉
Total Pallets = ⌈Gross Sheets ÷ Pallet Capacity⌉ (15mm: 50 | 18mm: 40 | 21mm: 30)

Selecting the Waste Allowance

In addition to standard 125×250cm panels, our 62.5cm narrow filler panels and custom-length extrusion (e.g. 280cm, 300cm) minimize jobsite cutting waste down to 2%.

Sheet Count Estimator FAQ

Frequently Asked Questions

Common questions regarding board selection, reuse cycles, technical parameters, and global delivery.

What do hollow, honeycomb, and solid core describe?

They describe the internal cross-sectional geometry of the board. Honeycomb and cellular structures provide lightweight handling, while solid core boards offer different deflection and impact dynamics.

Can an 18 mm board be used in all formwork types?

Thickness alone does not determine full suitability. Polymer structure, fresh concrete hydrostatic pressure, support joist spacing, and framing connections must be evaluated within a proper formwork design.

How does the board behave in hot and cold weather?

Thermopolymers expand in heat and gain rigidity in severe cold. Therefore, an expansion joint gap (1.5 – 2 mm) recommended by the manufacturer should be maintained at board joints.

How are plastic formwork board prices determined?

Pricing is determined by thickness (15, 18, 21 mm), cellular honeycomb engineering, order volume (sheets, pallets, full container/truckload), and delivery terms (jobsite, warehouse, or seaport).

What is the typical order lead time and delivery period?

In-stock domestic orders are dispatched within 1–3 business days. Custom dimension orders or ocean freight container shipments are prepared within a 7–15 business day lead time.
