How to choose fire rated backplate door handle
Firstly, When choosing a fire rated backplate door handle, it's important to consider the EN1906 standard. This standard specifies the requirements for door handles. A handle that meets this standard is guaranteed to be of high quality and long-lasting.
Secondly, the material is also important when you choose a door lever handle. The high melting point of the stainless steel provide high fire resistance for the lever handle, which is better than zinc alloy and aluminium.
