I'm looking for a fabrication partner for a short run of a residential pull-up bar made from stainless steel. The design is straightforward, but quality is key—think precise tube bending, robust welds, and a polished finish suitable for home use. I'd like quotes for 1 prototype, plus initial runs of 10, 25, and 50 units. Could you confirm if this project aligns with your capabilities? Also, please provide pricing, lead times, material and finish recommendations, and details on whether you handle bending, welding, and finishing in-house. Lastly, share your quality control processes, setup costs, and for overseas suppliers, include shipping terms and estimated costs to Berkeley, CA.
