Keystone Tower Systems Information

Keystone Tower Systems is a rapidly growing company developing a new manufacturing process for wind turbine towers. Our automated tower production system brings modern manufacturing to the steel tower industry, dramatically increasing production rates and unlocking new possibilities for welded steel towers. Keystone's process can be operated at the wind project, enabling towers that are far larger than today’s transport constrained towers. Keystone is currently working with leading wind turbine manufacturers to integrate large diameter, field-welded towers into their turbine offerings, enabling welded steel towers to reach hub-heights in excess of 140m. Our process can also be added to a conventional tower factory - eliminating the need for manual welding lines through a single machine that simultaneously performs all rolling and welding operations and increasing tower output by 50%.
