In 1942, Ronald M. Guntert, Sr. formed a limited partnership with Hickinbotham Bros. and L.R. Zimmerman for the purpose of fulfilling major World War II contracts. Hickinbotham Bros., Ltd., was a highly regarded steel company in the San Joaquin Valley. The partnership was known as Hickinbotham Bros. Const. Div. who established its shipyard on Banner Island in the Stockton Channel.
     
During the war, Hickinbotham Bros. Const. Div. entered into contracts with the Navy and the Army Transportation Corp. for the construction of floating crane barges, landing crafts, steel tug boats, and 176 ft. Inter-island supply vessels. These contracts were completed so effectively under a management whose main characteristics were integrity and outstanding ingenuity that on August 27, 1944, the Army-Navy Production Award (E) was presented to: "The men and women of Hickinbotham Bros. Const. Div." At the peak of the war, the partnership employed over 600 people.

Shortly after the war, Ronald Guntert and L.R. Zimmerman acquired Hickinbotham's interest and incorporated as Guntert & Zimmerman Const. Div., Inc. In 1948, Guntert and Zimmerman formed a steel supply division to augment their material needs, which was called Guntert & Zimmerman Sales Div., Inc. The supply division changed its name to Guntert Sales Div., Inc. in 1961, and it is more commonly known as Guntert Steel.
