Making Things Better, Faster, Safer for Six Decades
Since the 1960s, we have pushed the boundaries of what is possible in efficiency, safety, and reliability. Our pioneering vision has led to game-changing solutions for positioning, restraining, and lifting heavy loads for the shipyard and oil and gas industries. And we bring that same commitment and talent to innovations for the burgeoning offshore wind industry.
To date, Bardex® has been awarded more than 20 U.S. and international patents. Visit our History page to take a deeper dive into our achievements.
