Each week, our Proud to Manufacture in Michigan team picks from more than 1,000 member companies to name a Featured Manufacturer of the Week. Our latest winner is Spartan Steel Coating!

Featured Manufacturer of the Week


Spartan Steel Coating produces more than 600,000 tons of light-gauge, hot-dipped, galvanized steel each year. Operating out of Monroe, Mich., Spartan Steel primarily serves the automotive industry.

Spartan Steel is a subsidiary of Worthington Industries, North America’s premier value-added steel processor, producer of laser welded products and a leading global supplier of pressure cylinders and accessories. Worthington Industries was founded in 1955 when a young steel salesman saw an opportunity in the custom-processed steel market. The company now provides customers with wide-ranging capabilities, products and services through a number of subsidiaries like Spartan Steel. Their companies have built a reputation on quality, safety and regulatory compliance.

Due to the expertise and quality they provide to customers, Spartan Steel has been chosen as Proud to Manufacture in Michigan’s latest Featured Manufacturer of the Week!
