A Troy-based paint finishing system supplier plans to buy property in Detroit to expand its operations there as part of a $9.27 million investment, according to the state.

Gallagher-Kaiser Corp. aims to add 300 jobs as it grows its Detroit manufacturing operations, according to a memo from the Michigan Economic Development Corp.

The Michigan Strategic Fund approved Tuesday a $3.2 million grant to support the supplier's anticipated investment. Jobs would be created in Detroit and Troy, the MEDC memo said. It also expects a property tax reduction through the city of Detroit.

As its plan stands, Gallagher-Kaiser would buy two parcels and renovate a vacant building next to its existing Detroit facility.

Currently, it subcontracts some manufacturing work outside of Michigan. The expansion would allow it to end most of its outsourcing, the memo said, with Gallagher-Kaiser completing more work using Michigan employees.

Gallagher-Kaiser was founded in 1952. It serves the automotive industry with customers including Detroit-based General Motors Co., as well as aviation, hospitality, government and aerospace.

It also has an office in Monterrey, Mexico, according to its website.
