EN 45545 HL3 Silicone Rubber Flexible Gangway
The fabric for the bellows is made of silicone rubber and aramid, which obtains excellent flame retardant properties and outstanding strength. With the proven technique, the fabric is structured to be flexible bellows with aluminum frames. The flexible gangway is installed between two adjacent carriages to provide a safe and comfortable pass for passengers.
