Dry freight truck body panels are lightweight, impact-resistant sandwich panel systems engineered for ambient-controlled van bodies, designed to maximize payload while protecting goods from moisture, dust, and road vibration. The skins are available in FRP, aluminum, or pre-painted steel, allowing fleet operators to balance durability, vehicle weight, and surface appearance for each transport application.
The core options include polypropylene (PP) honeycomb at 28-50 kg/m³ density for maximum weight reduction, or extruded polystyrene (XPS) at 35-40 kg/m³ for added rigidity. PP honeycomb construction can reduce panel weight by up to 30% versus steel skin, and the complete panel is approximately 40% lighter than traditional metal bodies, directly increasing payload.
Standard thickness ranges from 50mm to 75mm, intentionally lighter than refrigerated panels to optimize payload capacity for ambient freight. Panels are produced in widths up to 2,700mm and custom lengths up to 10,000mm, manufactured by vacuum lamination or press bonding with skin-to-core adhesion exceeding 100 kPa per EN 14509 for long-term durability.
These panels serve express parcel delivery, FMCG distribution, electronics transport, general ambient freight, and moving vans. UV-stable gel-coated FRP skins resist yellowing under prolonged sun exposure, while aluminum skins use PVDF coatings that deliver 15+ years of weathering resistance, preserving appearance and structural integrity throughout vehicle service life.
Your Trusted Manufacturer for Dry Freight Truck Body Panel
RaxPanel produces dry freight truck body panels at our Hebei, China facility with a focus on weight optimization and surface coating durability. Our press bonding and vacuum lamination lines handle PP honeycomb, XPS, and hybrid core configurations, with in-line thickness gauging that holds panel tolerance within ±0.5mm across the full 2,700mm width.
Surface finishing is managed in-house: gel-coated FRP skins receive UV-stabilized topcoats, while aluminum skins are coil-coated with PVDF systems rated for 15+ years of outdoor weathering. With a daily production capacity exceeding 1,700 m² and exports to more than 30 countries and regions, we supply body builders who need consistent panel weight and surface quality across fleet-scale orders.

Dry Freight Truck Body Panel Selection Guide
Dry freight body panels prioritise impact resistance, low tare weight, and weather sealing over thermal performance. The guide below covers the skin, core, and joint decisions that determine cargo protection and body longevity.
Pro Tip: Prioritise Skin Impact Resistance Over Core Thickness
Dry freight bodies face constant cargo impact and strap abrasion, not extreme thermal loads. Specify 2.0 mm gel-coat GRP or aluminium skins with hardwood floor bearers at forklift wheel paths, and keep core thickness at 25-50 mm to minimise tare weight.
Dry freight bodies face constant cargo impact and strap abrasion, not extreme thermal loads. Specify 2.0 mm gel-coat GRP or aluminium skins with hardwood floor bearers at forklift wheel paths, and keep core thickness at 25-50 mm to minimise tare weight.
1. Skin material selection for cargo protection
Gel-coated FRP at 1.5-2.5 mm is the standard interior skin for dry freight bodies because it resists abrasion from sliding cargo and is easy to repair after impact. Aluminium skins at 1.0-1.5 mm save weight but dent under point loads. For exterior surfaces, pre-painted galvanised steel at 0.5-0.7 mm provides UV and stone-chip resistance at the lowest cost.
2. Core options and weight trade-offs
Dry freight panels use thinner cores than refrigerated bodies because thermal insulation is not the primary function. XPS at 25-50 mm provides basic weather insulation and panel rigidity at minimal weight. PET foam cores offer higher compressive strength for bodies that carry stacked pallet loads against the walls. PP honeycomb cores are the lightest option at 15-25 mm for weight-sensitive applications.
3. Floor construction and forklift loading
Floor Load Design Checklist:
- Confirm maximum forklift axle load and wheel contact area
- Specify high-density PU core (≥ 60 kg/m³) or hardwood bearers at wheel paths
- Use 18-28 mm plywood or bamboo sub-floor beneath the panel for load spreading
- Seal all floor-to-wall joints to prevent wash-water ingress into the core
4. Joint sealing and weather protection
Panel joints use aluminium extrusion profiles with EPDM gaskets to shed rain and prevent dust ingress. Rear door frames are sealed with continuous compression gaskets and a stainless steel drip rail. For curtain-side bodies, the panel-to-curtain interface uses a flexible PVC strip that accommodates body flex during cornering.
Frequently Asked Questions
What panel weight can I expect per square metre?
A typical dry freight panel with 1.5 mm GRP skins and 30 mm XPS core weighs 5-7 kg/m². Aluminium-skin variants with PP honeycomb core drop to 3-5 kg/m² for weight-critical applications.
Can the panels withstand forklift impact?
Standard 1.5 mm GRP skins resist incidental contact. For frequent forklift loading, specify 2.0-2.5 mm skins or add a 500 mm high aluminium kick rail at the loading zone.
How are panels attached to the chassis sub-frame?
Panels bond to aluminium or galvanised steel sub-frames with structural polyurethane adhesive, supplemented by mechanical fasteners at 300 mm centres along the base rail. The adhesive carries shear loads while fasteners provide peel resistance.
What is the lead time for a custom body panel set?
Standard configurations ship within 15-20 working days. Custom dimensions, non-standard skin colours, or special core specifications add 5-10 days for tooling adjustment and material sourcing.
