Store trolley bumper rails and protection devices specifically designed for places such as cold stores, freezers and cold storage facilities. They are usually located around freezers, shelves and equipment to prevent accidental collisions and damage to freezers caused by forklifts, trolleys or other transport equipment during handling. The cold resistance, robustness and crash-proof design of the freezer barrier make it an important guarantee for cold storage facilities, while helping to reduce equipment maintenance costs and extend service life.
