Herculock specializes in securing two pieces of metal together in the repair of cracked or broken metal castings. We use a process called ‘Herculocking’ (also known as metal locking), to repair cracked or damaged castings. It’s a process we perfected over the 75 years we’ve done these types of repairs! The repairs can be done in our shop or on-site. The process has no heat applied and the result is no distortion or shrinking of the fully repaired metal casting. Herculock of Niagara Falls has provided a guaranteed service in Canada and the United States since 1944. Owing to the nature of our service, most clients have only an occasional requirement, thus, we have acquired a great number of diverse customers from a wide area.
