Flat Rock Metal is a family owned and operated high quality niche steel processor specializing in critical surface sheet and coil processing. Incorporated in 1981, we have grown to become the largest sheet polisher of carbon steel in North America. In the mid 1990's we embarked on a diversification and growth strategy, integrating upstream into coil processing, automotive blanking and specialty sheet processing niches.

We have surpassed a quarter century of specializing in critical surface processing and preparation. We've built a strong reputation servicing the automotive and steel industries, offering superior service and quality our customers have come to count on.

At Flat Rock Metal, we are toll-processors only, we don't sell steel. We're proud of the companies we serve, and we're not interested in competing with them. We are committed to raising industry standards in the area of critical surface material processing. We are dedicated to delivering just-in-time when our customer's requirements call for it. 

Flat Rock Metal prides itself on customer relationships. We work together with our customers on each job to ensure complete satisfaction. Because our only business is processing we are able to concentrate our efforts and our investment capital on being the premier processor in the industry. Our equipment is well maintained and regularly upgraded to utilize the most current technology. Our professional engineers and machinists receive extensive training and remain well informed of new techniques and industry trends. The most modern equipment, high quality service, and a strong partnership with our customers provide the foundation of our success. 

The Flat Rock, Michigan location houses our corporate offices as well as flat polishing and coating operations. Further, the facility houses a high production, unique 72” Cut-to-Length Multi-Blanking line. In late 2004 we installed a 72”, 400 ton Press Blanking line with oscillating cut and configured blank capabilities that now allows us to provide full service blanking to the automotive market.
