Detailed Description

1. Product Overview

High-density sponge door seals are specially designed for logistics loading docks. They feature a wear‑resistant PVC tarpaulin exterior enclosing high‑rebound closed‑cell sponge, which conforms tightly to the truck body when the vehicle is docked, effectively blocking cold and hot air, dust, and rain. With a simple structure that requires no complicated maintenance, these seals can be custom‑made to any size, making them ideal for standard warehouses, cold‑chain refrigerated facilities, and temperature‑controlled workshops in food processing plants—offering excellent sealing and thermal insulation at an outstanding cost‑performance ratio.
