Core Advantages

• Lightweight aluminum substrate, only 1/3 weight of steel plate, reduce truck dead weight, cut fuel consumption and raise payload

• Low temperature resistant coating, stable coating performance under -40℃ ~ +80℃ temperature cycle, no cracking or peeling in cold chain environment

• Outstanding anti-corrosion property, resist moisture, road salt and coastal salt spray, suitable for long-term refrigerated transport

• Smooth and easy-clean painted surface, convenient sanitization, meet hygiene requirement for food & pharmaceutical cold chain

• Good adhesion with PU foam insulation layer, perfect match for sandwich panel production of refrigerated cargo box • Excellent formability, suitable for roll forming, bending and stamping for truck body panel manufacturing

• PE / HDP / PVDF coating optional, white is mainstream color, custom RAL colors available

• Precise thickness & width tolerance, flat surface, compatible with automated truck panel production lines

• MTC, low temperature and salt spray test reports supplied for customer quality audit

Production Process

Aluminum jumbo coil uncoiling → Degreasing & cleaning → Chromate conversion pre-treatment → Primer + top coat baking curing → Surface inspection → Precision slitting → PE protective film lamination → Final dimension & appearance inspection → Export packing Each batch conducts low temperature bending test, coating adhesion test and salt spray test before shipment.

Technical Parameters

Coils placed on IPPC fumigated wooden pallets, fixed with packing straps and stretch film. Shipping marks mark alloy grade, temper, thickness, width, coating type, color code, net/gross weight and batch number. MTC, test reports and fumigation certificate available for customs clearance and incoming inspection.

FAQ

Q1: Recommended alloy for cold chain truck prepainted aluminum? A: 3003-H14 / H24 is most popular for general refrigerated trucks; 5052 for coastal high salt spray environment.

Q2: What coating grade for cold chain trucks? A: PE for inland cold chain; HDP for longer outdoor weather resistance; PVDF for coastal high UV & salt areas.

Q3: Can it withstand minus 40℃ low temperature? A: Yes, our special low-temperature formula coating will not crack under -40℃ cold cycling.

Q4: Is the material good for roll forming truck panels? A: Yes, balanced ductility and coating flexibility, no paint cracking during bending.

Q5: Can we get samples for lab low temperature test? A: Small test samples can be provided upon request.
