Core Advantages

· Comprehensive Weather Protection: Perfectly seals, 100% preventing rain, dust, mud, sand, and contaminants from entering the cargo hold, ensuring cargo safety.

· Excellent temperature resistance (-50°C to +70°C, temporarily up to +100°C) ensures resistance to deformation and cracking in extreme climates.

· Excellent insulation and energy saving (for refrigerated trucks): Low thermal conductivity effectively reduces cold air leakage, significantly improving refrigeration efficiency and helping customers significantly reduce operational energy consumption. It ensures stable temperatures inside refrigerated trucks and insulated containers, meeting food safety and pharmaceutical cold chain transportation standards.

· Durable and long-lasting: Excellent resistance to UV rays, ozone, and aging maintains performance even under intense use with frequent door openings and closings. The high-strength elastic material has low compression set, ensuring rapid recovery after extended use and providing long-lasting sealing pressure.

· Precise Fit, Easy Installation: Available in standard profiles such as T-shaped and I-shaped, they precisely match mainstream container, van, and refrigerated truck models. The rational design allows for easy installation and replacement, fitting into the rolled metal groove around the vehicle door for quick maintenance.
