Known for our quality and dependability, Johnson Brothers has been a leader in the roll forming industry since 1948. Our modern, high-tech facility houses more than twenty roll forming machines with up to 28 station capacity and is equipped with servo-driven die accelerators and die boosts, allowing us to obtain close tolerance accuracy. We have multiple presses for in-line punching, cut-off, and fabricating, including a cut-to-length ring press that allows us to produce custom-sized rings in one operation, from start to finish.

We roll form an extensive range of metals and alloys, and working with pre-finished types and grades is one of our strengths. Along with pre-anodized aluminum, pre-plated and pre-galvanized steel, and polished steel, we work with pre-painted metals as well as sheet and coil with laminated vinyl and pre-embossed strippable PVC finishes. We roll form raw materials measuring from .005” to .188” in thickness to generate parts from .187” to 20.00” wide and up to 36’ in length.

With capabilities for in-line and secondary slotting, bending, swaging, grooving, end pointing, deburring, etc., we can create roll-formed parts with simple to complex design features. We can apply adhesives or magnet strips, add rubber or plastic inserts, and clad different materials by forming them together. From small parts to rings, angles, channels, moldings, and just about any custom profile, we can obtain tolerances as close as ±.003 to ±.005 in critical areas.

Our quality management system complies with ISO standards, and we use a series of in-line quality checks, statistical process control, and final inspection to ensure parts conform to specifications. We serve customers in hundreds of different industries, making components for solar panels, retail displays, industrial racks and shelving, filters, appliances, and more.
