Dialum, a Chilean company that processes glass for use in homes and businesses, has begun site work in Ave Maria for a 100,000-square-foot factory just east of Arthrex’s manufacturing plants. This week, Naples-based Barron Collier Companies announced that Dialum finalized the acquisition of 10 acres for its U.S. headquarters in Arthrex Commerce Park along Oil Well Road just west of Ave Maria’s main entrance. Dialum Realty Inc. of Coral Gables purchased the acreage on Arthrex Commerce Drive for $2.5 million from Ave Maria Development LLP, part of Barron Collier Companies, according to Collier County property records. Miami-based Talba Group acted as Dialum’s broker during the transaction.
