Household Metals Incorporated traces its beginnings to 1983 as a manufacturer of sheet metal and steel radiator covers with roots in the machining industry. Over the following years, HMI's customer base continued to expand due to its ability to interact with customers on a more personal level. As HMI's experience with steel fabrication progressed along with its success in the manufacturing industry, relocation to a larger facility on Scotts Lane in Northwestern Philadelphia was necessary to allow ample room for growth. In 1988, HMI's continuous drive for innovation led to the replacement of their line of sheet metal and radiator covers with steel security doors. Prosperity in the steel security door market allowed HMI to expand its growing product line in 1994 with a new line of steel entry doors. As HMI continued to establish itself as the premier steel security and entry door manufacturer in the tri-state area and beyond, headquarters were relocated to the current 135,000 square foot facility in the manufacturing district of Northeast Philadelphia.
