Two manufacturers that plan to create 120 jobs in North Charleston are in line to receive $350,000 in government grants to help offset their expansion costs.

Charleston County Council’s finance committee met Thursday to approve $150,000 in public funding for Eaton Corp. and $200,000 for Weber Automotive Corp.

The grants come from the S.C. Department of Commerce. The money must be used to defray the costs of infrastructure projects, such as sewer and road work, that are directly tied to the companies’ investments in the county.

Ohio-based Eaton Aerospace makes high-precision parts used in military equipment and commercial aircraft.

It’s proposing to create a $22 million “center of excellence” and add 22 jobs at its existing plant on Cross County Road, where it already employs 155 workers.

The county said Weber Automotive plans to invest $56 million and create 98 jobs at a new factory and North American headquarters at Palmetto Commerce Park off Ladson Road. The plant will make transmission components and other drive-train parts,

The German-owned company is expected to begin production in 2015.

According to figures in a county document, Weber Automotive has slightly increased its capital investment and employment projections from July, when the new factory was first announced.
