Mississippi economic officials say Vitro America LLC is expanding its operation in the state.
The company makes architectural glass and aluminum products.
The Mississippi Development Authority said in a news release Wednesday that Vitro America will create 20 jobs over the next three years by moving production of storefront metal systems to the plant in Grenada.
The plant makes safety glass and already has about 100 employees.
MDA says the company is investing $1.2 million in new equipment. The state provided $135,000 and the city of Grenada gave $15,000 for the plant expansion.
