U-channel Edge Protectors For Rail Metro Door Seal

This U-channel edge protection rubber profile, specifically designed for subway doors, is made of aging-resistant EPDM rubber and integrates sealing and protection functions. It effectively prevents impacts from opening and closing doors, reduces edge wear and noise, and blocks dust and rainwater from seeping into the door body. It is also UV-resistant and ozone-resistant, extending the lifespan of the subway door and reducing the safety hazard of passengers bumping into the door edges when boarding or alighting. It is ISO 9001 quality certified, CE EU safety certified, and RoHS compliant, meeting the procurement requirements of subway systems in major regions worldwide, including Europe, America, and Southeast Asia.

Guangdong Zhongxiang New Materials Co., Ltd. is a leading manufacturer and supplier of customized extruded and molded rubber products in China. We offer a wide range of square U-shaped rubber seals and gaskets, including ribbed profiles and co-extruded bases with sponge rubber bulbs. We can produce rubber U-channel profiles according to the dimensions of the train door edge (width, thickness, radians) provided by our customers. We offer a variety of compound materials, including high-temperature-resistant rubber, weather-resistant rubber, and high-elasticity rubber. We can also apply fire-retardant, fireproof, and anti-static coatings to meet specific safety standards for the rail metro. Custom colors are supported, including black, gray, and red, to match the application design.
