Tube Coiling

G & J Steel & Tubing, Inc. manufactures coiled tubular parts using several methods including our 6-axis CNC bender, a specially designed coil machine, and a serpentine bender. We can produce any shaped coil including helix, box, double, serpentine, and irregular shaped coils.

Our high quality coils are used extensively in heating, cooling and mechanical applications. We have made heat exchanger coils, condenser coils, oxygen warming coils, oil cooling coils and beverage coils. End forming and tube fittings (compression or flare nut) can be added to any coil shape.
