T type guide rail is the most widely used elevator guide rail in our country at present. It has strong versatility, good bending performance and machinability.

The L type rail has low rigidity and surface accuracy, and its surface is rough, so it can only be used for the counterweight rails of sundry elevators and various non manned elevators.

The hollow guide rail is made of thin steel plate, with higher accuracy than L, and has a certain rigidity. It is used for the heavy and low lift rail of the elevator without safety tongs.

The same elevator often uses two specifications of the elevator rail. Generally, the car guide rail is larger in size than the counterweight rail, so it is also called the main rail of the car guide rail. The counterweight rail is the auxiliary rail.
