Harold R. Henrich Sr. opened a modest sheet metal business in Hackensack, New Jersey, in 1942. Harold Jr. joined his father in the business and worked to expand it after serving in the US Navy. The business grew and relocated to a bigger location in Carlstadt, New Jersey, two years later. Due to their expansion, HRH became a legitimate custom metal fabrication business in 1978 and moved to a larger location in Saddle Brook, New Jersey. As the only laser-equipped metal fabrication shop in all of New Jersey, HRH became a genuine pioneer with the addition of a second laser/punch combo machine, constructed by Strippit.
