In the early 1960s, Harold and his brothers Alvin and Arnold (great-uncles of Kevin and Andy Kurstin of Wayland Industries) expanded into stainless steel and nickel alloy weld fittings by starting Sun Weld Fitting, Co. With Sun Weld, they serviced a rapidly-growing market in refining, petrochemical, food processing, breweries, marine and other industries. They grew their business to become one of the largest manufacturers on the West Coast.
