Elevator guide rails are components of elevator systems that define the path along which the elevators ride.
Data receivers which transmit to the control system the information about the position of elevators, doors, door locks
and safety brakes are designed on the assumption that guiderails will follow certain paths.
Guide rails are manufactured in fully equipped factories possessing high-quality measurement systems, we are the one of them.
Strict requirements for quality, strict control on quality, actively building the brand, the quality is the principle of jiefeng.
