DUBLIN -- Allegion plc has acquired privately held DCI Hollow Metal on Demand (DCI),  a leading U.S. manufacturer of custom, quick ship hollow metal doors and frames for industrial, commercial and institutional markets.

DCI solutions are installed in a wide range of facilities, including hospitals and medical centers, government buildings, K12 schools and universities, commercial offices and stadiums. DCI’s product line includes custom commercial steel doors, bulletproof doors, fire-rated doors, STC doors and hollow metal frame manufactured to customer specifications, in their 100,000-square-foot facility in Southern California.

DCI will operate as part of the Allegion Americas segment, led by Allegion Senior Vice President Dave Ilardi.      

“We are very excited to welcome DCI to Allegion,” Ilardi said. “DCI strengthens our core mechanical portfolio and leverages our go-to-market capabilities in non-residential markets, while expanding our presence on the West Coast. Together, we can better serve customers with a stronger local presence, faster response times and more tailored solutions.”

DCI CEO Bob Briggs will serve in an advisory capacity, supporting a smooth transition for the business as it joins the Allegion doors and frames portfolio, which also includes leading brands like Steelcraft, Republic Doors and Krieger Specialty Products.

“With our specialties being quick ship and customized doors, DCI is a highly customer-centric business – making us a natural fit for Allegion,” Briggs said. “We share their ‘partner of choice’ mentality, providing our customers what they need when they need it.”
