美国采购需求：镀锌钢卷、彩涂钢卷、彩涂镀锌钢卷、H型钢、Reba型钢、角钢

I'm looking to purchase 75 stainless steel tubes, specifically made from 304 material. Each tube needs to be 8 feet long with an outer diameter of 1 inch and an inner diameter of 3/4 inch. It's essential that they are polished on the interior to achieve a 20RA finish, as this will be crucial for my project requirements. Could you provide me with pricing details and let me know about availability? Additionally, it would be helpful to understand your lead times and any minimum order requirements. Looking forward to your prompt response so we can move forward smoothly. Thanks!
