Truss Manufacturing Co., a fixture along U.S. 31 in Westfield since 1959, in October changed its name to TMC Building Products to emphasize its expansion into other supplies.

“Our sales [people] spend a significant amount of time saying, ‘No, no, we do more than just trusses,’” explained President Chris Weintraut.

The privately owned company has about 30 employees and serves residential and light-commercial builders in a 200-mile area around Westfield.

Weintraut said roof and floor trusses account for half of all sales. The other half now comes from pre-fabricated wall panels, exterior sheeting, windows, doors and interior trim.

TMC began making wall panels about two years ago, and expanded into other product lines in the past six months.
