Cold Chain Truck Body Aluminum Panel

Core Advantages

• Lightweight high-strength aluminum substrate, 1/3 weight of steel plate, effectively reduce vehicle body weight, save fuel consumption and increase loading capacity

• Excellent corrosion resistance, adapt to cold chain humid, low temperature and coastal salt spray environment, no rust and no peeling for long-term use

• Food grade smooth surface, easy to clean and disinfect, fully meet food and pharmaceutical cold chain hygiene requirements

• Dense coating structure, resistant to low temperature brittleness, maintain stable performance under -40℃~80℃ temperature cycle

• Good bonding performance with insulation foam, perfectly match polyurethane foam sandwich panel production process

• High impact and scratch resistance, resist cargo collision and daily wear during transportation

• Customizable thickness, width and length, match various truck body size and splicing design

• Complete surface protective film, avoid scratch during transportation, cutting and installation

Production Process

Aluminum coil raw material feeding → Multi-cycle degreasing cleaning → Chromium-free food grade passivation → Constant temperature drying → Primer roller coating & low temperature curing → Food grade top coat coating & baking → Natural cooling → Anti-scratch protective film lamination → Fixed-length cutting → Flatness inspection → Coating adhesion test → Low temperature resistance sampling test → Stacking & dust-proof export packaging.

Each batch undergoes salt spray test and low temperature resistance test before delivery to guarantee stable performance in cold chain environment.

FAQ

Q1: What is the advantage compared with steel truck body panel?

A: Aluminum panel is only 1/3 weight of steel plate, which can reduce vehicle body weight by 30-40%, save 10-15% fuel consumption, and will not rust in cold chain humid and salt spray environment, service life is 2-3 times longer than steel plate.

Q2: Does it meet food cold chain hygiene requirements?

A: Yes. The surface coating is food grade, non-toxic and odorless, complies with FDA and LFGB food contact standards, smooth surface is easy to clean and disinfect, fully suitable for food and pharmaceutical cold chain transportation.

Q3: Can it be bonded with insulation foam?

A: Yes. The surface has been specially treated to have excellent bonding performance with polyurethane foam, rock wool and other insulation materials, which is suitable for sandwich panel production of refrigerated truck body.

Q4: How is the low temperature resistance?

A: The special cold-resistant coating formula can maintain stable performance under -40℃ low temperature environment, no cracking, no brittleness and no peeling under long-term low temperature cycle.

Q5: Can you customize special size for truck body?

A: Fully supported. We can produce customized thickness, width and length according to customer truck body design drawings, which perfectly matches different vehicle body splicing structures.
