Manufacturing

Manufacturing is supported by three factories; Richmond, BC, Cheney, WA, and Kingston, ON. Utilizing a wide range of materials and diverse suppliers, each component is custom made for the specific unit; from access doors to fanbases.

Each factory leverages state of the art equipment to ensure the highest level of quality and each unit undergoes an extensive quality control unique to each and every unit.
