Capitol Steel & Iron LLC

A Reputation for Reliability
Founded in Oklahoma City in 1910. Capitol Steel's first years were spent fabricating reinforcing steel. Eager to secure a larger share of the construction market, we expanded into the structural steel business in 1929.
Upon completion of our plant in 1930, the country was mired in its worst depression. During the lean years that followed Capitol managed to grow by building additional structures and buying new equipment when finances permitted.
Our growth has continued and today Capitol Steel is serving the national market as a leader in the bridge business. Our reputation lies in getting the right material to the job - on time - at a competitive price.
