Sweeney Metal Fabricators was started in October 1988 by John Sweeney. It began with a small desk in the basement of his home and borrowed equipment in a friends’ Amherst, NH shop. The company soon grew into its own space as it acquired equipment, employees, and most importantly, a strong customer base.

Quality, Affordability, On Time

The company was built on simple, yet powerful principals: the highest quality, most affordable, product, delivered on time. Keeping this in mind, John never forgot who was the most important of all: customers.

Twenty-five years later, John is still at the helm, driving the company into the future of manufacturing. Many customers have been on the twenty-year ride, as well as some employees. Sweeney Metal Fabricators has made its home in Nashua for the past seventeen years and has grown from one employee in 1988 to 25 employees in 2013. The large customer base touches on most sectors of manufacturing. From high-tech, medical, and military, to restaurants and RVs, open doors and open ears have put Sweeney Metals where it is today.
