Central Steel is committed to producing a product that meets contract and customer requirements.  

Central Steel has a long and rich history

in the steel industry stretching more than

60 years. In 1950 Robert Aaby moved to

Wichita Kansas, from Wisconsin, and

founded A&A Welding. During the late

60s Robert hired his two sons, Jim

and Richard, who evolved A&A Welding

to incorporate larger scale steel work, providing fabrications for locks and dams around the nation. In 1970 Jim and Richard officially changed the companies name from A&A Welding to

Central Steel Inc, to better reflect the wider range of steel work they were involved in. During the early 80’s a third generation of family had begun to integrate into the family business, and again pioneered growth and evolution within Central Steel. Diversifying Central Steels fabrications to include work in commercial buildings, these current officers of Central Steel grew what was once a small welding operation into a company responsible for many of the Schools, Hospitals, Power Plants, and other buildings around the mid west today.
