Everything you need to know about our hollow plastic boards, PP corrugated sheets wholesale, reusable concrete formwork, and custom manufacturing from our China factory.
General questions about PP corrugated sheet properties and characteristics.
PP corrugated sheet features a hollow flute structure sandwiched between two flat outer layers. This I-beam-like core design delivers an exceptional stiffness-to-weight ratio, making the sheet lightweight yet strong. In contrast, a solid plastic board is heavier, uses more raw material, and costs more per square meter.
For most construction and industrial uses, PP corrugated sheet offers the best balance of strength, weight, and cost.
Yes, 100% recyclable. Polypropylene (PP) is a thermoplastic, which means scrap material and end-of-life panels can be reground, melted, and reprocessed into new products without quality degradation.
Using our recyclable plastic formwork can contribute toward LEED and BREEAM green building certification points.

Pricing, MOQ, lead time, shipping and sample policies for bulk buyers.
For standard-size PP corrugated sheets, the minimum order quantity is 500 pieces per specification. For custom size orders, the MOQ is also 500 pieces per spec, though this can be negotiated for larger dimensions or trial orders.
We welcome mixed containers combining multiple sizes, colors, and product types to help buyers optimize shipping costs. Contact our sales team to discuss your specific requirements and we will tailor a solution.
Yes, we maintain a 3,000-square-meter indoor warehouse with constant stock of our most popular sizes: 1200×2400 mm, 1220×2440 mm, and 915×1830 mm in common thicknesses and colors.
✅ For in-stock standard sheets:
Lead time: 7 to 14 days from order confirmation to container loading. We can typically arrange shipment within 10 working days for most standard orders.
For custom sizes, lead time is 10 to 18 working days depending on quantity and whether new tooling is required.
Our large warehouse capacity means we can buffer seasonal demand spikes and maintain consistent supply even during Chinese holiday periods.
Sea freight from our factory in Zhejiang, China (adjacent to Ningbo & Shanghai ports):
For urgent or sample orders, air freight or express courier (DHL, FedEx, UPS) is available — typically 5–7 working days door-to-door.
Yes, we offer free samples for qualified buyers and serious inquiries. Simply contact our sales team with your desired thickness, size, color, and application details and we will prepare the appropriate samples.
Sample orders are strongly recommended to verify material quality, surface finish, dimensional accuracy, and suitability for your specific application before placing a bulk order.
Technical specifications and comparison between plastic formwork and traditional plywood.
30 – 50+ cycles under normal construction conditions.
Our reusable concrete formwork plastic panels are engineered to maintain structural integrity through 30 to 50 or more pour-and-strip cycles. Each panel retains its flatness, strength, and surface quality throughout its lifespan.
Compare this to traditional plywood formwork, which typically lasts only 3 to 5 uses before warping, delaminating, or absorbing moisture.
Cost impact: At 50 uses vs. 5 uses for plywood, the per-cycle cost of plastic formwork is typically 60–70% lower than plywood over the full lifecycle.
| Feature | Plastic Formwork | Plywood Formwork |
|---|---|---|
| Reusability | 30 – 50+ times | 3 – 5 times |
| Water Resistance | 100% waterproof, no swelling | Absorbs moisture, swells & delaminates |
| UV Resistance | UV-stabilized, no degradation | Not UV resistant, surface cracks |
| Weight (15mm panel) | ~12 kg / m² | ~17 kg / m² |
| Concrete Surface Finish | Smooth, requires minimal plastering | Rough, often requires extensive patching |
| Recyclability | 100% recyclable | Landfill or incineration |
| Long-term Cost | 60–70% lower per cycle | Higher per-cycle cost due to frequent replacement |
In summary, plastic concrete formwork is the clear winner for projects that demand consistent quality, lower labor cost, and sustainable construction practices.
Yes. Hollow plastic formwork panels have an operating temperature range of −20 °C to +80 °C. Unlike plywood, plastic does not absorb moisture and therefore will not freeze, crack, or delaminate in sub-zero conditions.
However, we recommend handling panels with care below −10 °C as the material becomes slightly less flexible. For winter construction projects in cold climates, plastic formwork is actually more reliable than plywood.
Custom size, OEM/ODM, tooling and qualification process.
The MOQ for custom size hollow plastic boards is 500 pieces per specification. Lead time is 10 to 18 working days depending on complexity and whether new tooling is required.
Absolutely. We strongly recommend sample approval before mass production. For standard products, we can send free samples from our existing stock. For custom sizes, we can produce pre-production samples for your approval.
The sample process typically takes 7 working days for custom items. Once the sample is approved and the purchase order is placed, production begins within 2 working days.
Yes, we provide full OEM and ODM services including:
Our in-house mold workshop can produce new extrusion dies within 7 to 10 days for unique profiles and custom flute designs.
Our sales engineers are ready to help with technical specifications, pricing, and customized solutions for your project.
