Company Overview
Johnson Bros. Metal Forming Co., located in Berkeley, Illinois, a suburb of Chicago, is a highly experienced and family-owned manufacturer specializing in custom roll-formed metal parts. Established in 1948 by Edwin Johnson Sr., the company has grown from a basement operation to a sophisticated facility, proudly serving American, Canadian, and international companies. Johnson Bros. is recognized for its comprehensive capabilities in transforming various metals into complex profiles and mouldings, maintaining a strong emphasis on quality, precision, and customer satisfaction.
Extensive Product & Service Portfolio
The company offers an expansive range of roll-formed products, including C-Channels, Box Channels, Strut Channels, Angles, Z-Channels, and various types of open, lock, flanged, finned, split, and hemmed seam tubing. Their offerings extend to specialized items such as barricade legs (Type I, II, III), closet rods, wardrobe bars, drip edges, fence rails, DIN rails, bus bars, wireways, cable trays, scuff plates, roof bows, sink mouldings, security storm door frames, RV luggage rack tubing, and components for windows, doors, shades, and blinds. They also produce decorative and functional rings, rims, clamps, flanges, holders, mountings, edgings, trim, retainers, frames, diffusers, grills, baffles, slats, strips, gaskets, and heat transfer plates.
Advanced Manufacturing and Materials
Johnson Bros. operates over 20 roll forming machines, some with up to 28 stations, capable of processing metals from .003' to .188' thick and coil widths from .187' to 20'. They work with a diverse array of materials including steel, stainless steel, aluminum, brass, copper, bronze, various alloys, galvanized, titanium, and pre-finished options such as prepainted, preplated, preanodized, and PVC-coated metals. A key capability is their inline fabrication, which integrates punching, slotting, notching, mitering, cut-to-length, embossing, and even material insertion (like tape or felt) directly into the roll forming process, enhancing efficiency and accuracy while reducing costs.
Commitment to Innovation and Quality
The company distinguishes itself through continuous innovation, developing proprietary techniques to produce complex parts like side-ways bent channel rings, offering solutions that were previously only possible through more expensive methods like stamping or spinning. Their in-house tooling design and construction, coupled with a large inventory of existing dies, allow for cost-effective and timely production for both small and large runs. Johnson Bros. maintains rigorous quality control, ensuring dependable tolerances and consistent finishes. With a strong financial standing and an outstanding safety record, the company provides reliable and expert roll forming solutions.
