Lock Steel Building Company, Inc., has been a Midwestern leader in steel buildings and based out of Carrollton, MO, for over 65 years. Founded in 1946 by brothers Herb and Bob Lock as part of Lock Brothers, Inc., Lock Steel Building has supplied and erected quality metal buildings for numerous agricultural, commercial, industrial, projects throughout the Midwest.
In 1971, Herb’s son, Don, joined the business and led with his knowledge and expertise for over 35 years. In 2000, Don’s son, Matt, accompanied his father and gained the experience passed on from the previous generations. Today, Matt Lock, grandson and nephew of the founders, oversees the day to day operations from sales to project management.
