Sponge door seals reduce energy consumption and improve the working environment. The door seal is made of thin plate liner with simple design, which is far more durable than the traditional wooden liner. In addition, the unique decompression design effectively reduces the friction between the goods platform door seal and the truck, prolong the service life of the door seal fabric. Wear-resistant window fabric construction The use of wear-resistant base material, durable and durable internal high-quality foam material, with 98% recovery and flexibility at temperatures below -40°C. Sponge cushion With anti-wear, prolong the service life of the door seal. Electroplated steel plate liner Avoid the potential problems of distortion, perishables and corrosion that may occur in the past wooden liners. Wear-resistant pleats Distributed on both sides and above to provide additional wear protection and effectively extend the service life of the door seal. Yellow warning note The use of reflective performance of the warning strip, with better safety. Seal performance for different heights Adjustable top design, reduce air convection, reduce the loss of cold storage temperature to achieve the effect of energy saving The counterweight balancing system is more easily adjusted Stainless steel chute and pull-down handle have better rust and corrosion resistance. The design of the bottom sealing block effectively reduces the gap in the lower part of the car.
