A CompoDeck panel is a thermoplastic sandwich panel engineered specifically for flooring and decking applications in transport vehicles, scaffolding, and industrial platforms. It combines glass-fibre-reinforced thermoplastic skins with a PP honeycomb or PP foam core to deliver a structural floor panel that is significantly lighter than plywood or steel while matching or exceeding their load-bearing performance. The sections below answer the most common questions about how CompoDeck is built, where it performs best, and what it means for your total cost of ownership.
What makes CompoDeck different from standard floor panels?
CompoDeck differs from standard floor panels in three fundamental ways: it is a sandwich panel rather than a solid sheet, it uses thermoplastic composite materials rather than wood or metal, and it is engineered to be structurally self-supporting without an additional subframe. Where a plywood floor relies on an aluminium or steel support structure beneath it, a 30mm PP sandwich panel floor carries its own load, removing a production step and reducing overall vehicle weight in a single change.
Standard plywood panels absorb moisture, swell at the edges, and degrade under repeated wash-down cycles. Steel floors add dead weight that directly reduces legally permitted payload. CompoDeck addresses both problems simultaneously: the thermoplastic core and skins do not absorb water, and the sandwich construction achieves high stiffness at a fraction of the weight of steel.
Fire performance is also a differentiator. CompoDeck panels carry a Bfl-S1 classification under EN 13501-1:2018, meaning limited flame spread and very low smoke production. That rating matters for regulated transport and interior applications where standard plywood would not qualify without additional treatment.
For EV fleet operators and truck body builders specifying electric vehicles in 2026, the weight argument extends beyond payload. Every kilogram of structural dead weight reduces battery range per charge. Lighter body structures directly extend the operating range of electric trucks and vans, making weight reduction a range argument as much as a payload argument. This is now a standard procurement question from EV fleet buyers, and a composite floor panel is one of the most straightforward structural changes available.
What materials is a CompoDeck panel made from?
A CompoDeck panel is built from two main components: glass-fibre-reinforced thermoplastic skins bonded to a PP honeycomb core. The skins contain 66 to 67% glass fibre by content and are available in 2-ply or 4-ply configurations depending on the load requirements of the application. The 4-ply black anti-skid skin is the standard choice for flooring, providing a finished surface without additional treatment.
The PP honeycomb core uses an 8mm tube diameter and is available at a density of 140 kg/m³ for most flooring applications. This honeycomb geometry distributes compressive and shear loads efficiently across the panel, which is why the sandwich construction achieves structural performance that a solid sheet of the same weight could not match.
All materials are thermoplastic, which has two practical consequences. First, the panels are fully recyclable and compatible with EU End-of-Life Vehicle (ELV) Directive requirements, a compliance consideration for many European OEMs, not just a preference. Second, thermoplastic skins can be welded, bent, and edge-sealed, which protects the core from UV exposure and moisture ingress during regular wash-down cycles.
The panels are validated against European standards. UV resistance is confirmed at 2,000 hours of direct exposure per ISO 4892-2:2006. Alkaline ageing resistance is tested at 50°C for 500 hours, relevant for flooring environments exposed to cleaning chemicals. Flexural performance is assessed per ISO 14125, and tensile properties per EN ISO 527.
What applications is CompoDeck designed for?
CompoDeck panels are designed primarily for truck body floors, trailer decking, and scaffolding boards, applications where composite panels deliver clear advantages over plywood or steel alternatives through the combination of low weight, high load capacity, moisture resistance, and long service life.
Transport and commercial vehicle flooring
In truck bodies and trailers, the floor panel takes repeated point loads from pallet trucks, forklift tines, and heavy cargo. CompoDeck handles these loads without the delamination or surface degradation that shortens plywood floor life. The panel’s self-supporting structure means no aluminium subframe is required beneath it, which simplifies the body builder’s assembly process and reduces the number of components in the floor build.
The standardised panel format of 2,440mm × 1,220mm fits directly into existing design workflows. No hardware changes or redesign are required, any system that currently accepts plywood panels accepts CompoDeck without modification. Refurbishment personnel need no retraining.
Scaffolding platforms
For scaffolding applications, the relevant benchmark is EN 12811 load class 4, which a 10.5mm Compoform panel achieves with no support underneath. That is a verified test result, not a general claim. The lighter panel weight reduces the physical effort of erecting and striking scaffolding, and the thermoplastic surface does not splinter or rot when left outdoors through wet seasons.
Marine decking and industrial platforms are also viable applications where UV resistance, fire classification, and mechanical strength are required together, though commercial vehicles and scaffolding represent our primary focus in 2026.
How does CompoDeck reduce total cost of ownership?
CompoDeck reduces total cost of ownership primarily through extended service life. Thermoplastic composite floors last 12 years or more in heavy transport use. Plywood floors in the same environment typically last 3 to 5 years before requiring replacement. Over a 15-year vehicle life, that difference eliminates two to three plywood replacement cycles, and each cycle carries not just panel cost but installation labour and vehicle downtime.
When you account for panel cost, fitting labour, and the revenue lost while a vehicle is off the road for a floor replacement, the composite panel is cheaper per year of service even at a higher unit price. One CompoDeck lifecycle effectively replaces four to five plywood replacement cycles over comparable operational periods.
Additional savings accumulate across several operational areas:
- Payload efficiency: A lighter floor increases the net payload available per trip, converting structural dead weight into revenue-generating cargo capacity.
- Freight efficiency: Lighter panels reduce the weight of each shipment during delivery, improving logistics economics across the supply chain.
- Handling time: Lighter panels reduce the labour required during installation and refurbishment.
- Waste disposal: Thermoplastic panels do not carry the treated-wood landfill costs associated with end-of-life plywood, and they comply with EU ELV recyclability requirements.
- Range for EV fleets: In electric truck applications, every kilogram removed from the body structure extends battery range per charge, reducing energy cost per kilometre over the vehicle’s operating life.
The lifecycle carbon impact is also lower. A longer-lived panel that requires fewer replacements generates less manufacturing and disposal activity over the vehicle’s life, which supports CSRD sustainability reporting requirements that European OEMs increasingly face.
What custom dimensions and configurations are available?
Panels are available in custom dimensions cut to your exact specification. The maximum panel size across our production range is 13,500mm × 2,900mm, produced on a 72-metre semi-automatic continuous production line. This means a single panel can span the full floor length of most trailer and truck body configurations without a join, eliminating a potential weak point and simplifying installation.
Thickness ranges from 11mm to 30mm depending on the structural requirement. Core density can be adjusted within the PP honeycomb range to tune the stiffness-to-weight ratio for your specific load case. Skin architecture choices, 2-ply or 4-ply, white PET-film or black anti-skid, allow the surface finish and mechanical performance to be matched to the application without over-engineering the panel.
Edge treatments including sealing and bending are available to protect the core from moisture and UV at the panel perimeter. This is relevant for truck floors washed down regularly and for scaffolding boards left outdoors between uses, where an unsealed edge would allow water ingress into the core over time.
For scaffolding applications, a 120 kg/m³ PP honeycomb core is available alongside the standard 140 kg/m³ option, providing a lighter board where the load class permits it. All configurations are produced at our ISO-certified facilities in Beek and Ospel, the Netherlands, with strict quality control applied to every production batch.
How Compoform Helps with CompoDeck Panel Selection and Integration
We work with truck body builders, trailer manufacturers, and scaffolding companies to identify the right panel configuration before production begins, not after a problem appears on the assembly line. That means reviewing your floor design, load requirements, and assembly process together, and recommending the skin architecture, core density, thickness, and edge treatment that fits your specific application.
Here is what that process looks like in practice:
- Design review: We assess your current floor specification and identify where a CompoDeck panel replaces your existing material without requiring structural redesign.
- Configuration recommendation: We specify core density, ply count, surface finish, and thickness based on your load case and assembly method, not a generic datasheet.
- Custom dimensioning: Panels are cut to your exact dimensions, including full trailer-length single panels where the application allows it.
- Integration support: Our team is available through the integration phase to address fit, fixing, and edge treatment questions, not just at the point of sale.
- Ongoing supply continuity: With 1.5 million square metres of annual production capacity and European manufacturing, we provide the lead time reliability and post-sales support that mid-volume OEM production schedules require.
