Greg's Welding

Greg's Welding is locally owned and operated since 1983. We can do any job large or small, in both the field and shop. Greg has also built a very innovative and successful heater treater complete with plumbing and the works. We are set apart from other companies because we prepare our systems so they are ready for installation. Our heater treaters and treater buildings are fabricated to customer's specifications. Once they are completed and finished to the highest of standards, we transport and set the treaters and other systems.
