Quality Control

St. Hans implements a standardized quality control system.

Contact us to know the " St.Hans Quacity Control System"

Each actuator, from the selection of raw materials, parts processing, finished product assembly, even outsourcing control, are fully in accordance with the st. Hans standardize quality control process

Each actuator has a serial number printed by the laser.
