MMC is an industry-leading roll forming manufacturer that supports high-volume projects across the United States. As a domestic partner, we perform all aspects of the roll forming process in-house at our Michigan-based facility and thoroughly test for quality before shipment. By investing in state-of-the-art equipment, we can form aluminum, steel, and other materials into precise profiles and to the tightest tolerances. Plus, we help our customers reduce expenses and lead time by providing pre-made tooling for standard profiles, including J-channels, at no additional cost.
How can MMC support your next project?




MMC can roll form J-channels from a variety of materials, although we most commonly work with aluminum and mild steel. We can process up to 300 feet of material per minute and up to .200” thick, and hold tolerances as tight as +/- 0.010”. Additional in-house capabilities include embossing, galvanizing, and anodizing, and for easier assembly, pre-piercing and notching. We also help our customers by providing warehousing and logistics solutions to ensure your products arrive on time with minimal delays.
