Precision round tubing for garage door systems — counterbalance shafts with burr-free bearing-fit ends, door-track tube, and cam tube with gaged ID and OD and straightness to .010″ per foot, from Mansfield, Ohio.
Garage door tube has to mate with hardware: a bearing slides over the shaft end, a cam rides the tube, rollers run the track. That makes it fit-up work, not commodity work — burr-free ends, gaged ID and OD on the same part, and straightness specs most tube never sees. It's the most precision-demanding segment we serve, and it runs on the same five mills as everything else.
Materials: G30 galvanized, HRPO, and hot rolled C1020 per application. Spec: ASTM A513 — see round tubing tolerances for the published baseline; precision items run tighter by agreement.
Three precision round-tube families: counterbalance shaft tube (0.995″ OD in 12–16 ga, G30 galvanized or HRPO), door-track tube (1.315″ OD, 10 ga, C1020 hot rolled), and light-gage cam tube with both ID and OD gaged. All manufactured to ASTM A513 with tight OD control.
Yes — shaft tube ships with no burrs so a customer-supplied bearing slides over the tube end without rework. It's the controlling requirement on our garage-door shaft specs, and it's inspected as part of the run.
Down to .010″ per foot by agreement on precision items like cam tube — the tightest straightness spec we run — with dual ID and OD gaging on the same part.
A truckload — roughly 45,000 lb. Send your OD, gage, material, end condition, and quantity with your RFQ and we'll confirm, along with current lead time.
