Roll-Formed Profiles: J-Channel

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.
