印度采购需求：热轧无缝管

We are looking for several types of tubing and bars for our upcoming project. First, we need round tubing with specific diameters and thicknesses in a certain grade, with a total of three different specifications and varying quantities. In addition to that, we also require galvanized pipes of a specific diameter and wall thickness, available in either welded or seamless options. Lastly, we are interested in high-stress round bars, treated to meet certain finish requirements, in substantial lengths. Please provide us with pricing and availability for these items mentioned above. We would appreciate if you could also share any lead times or minimum order quantities that might apply. Your prompt response would be appreciated.
