美国采购需求：钢管、钢卷及钢板、钢棒、不锈钢板、不锈钢管、不锈钢棒

I'm reaching out to get a quote for hot rolled steel sheet piles with specific requirements. We need the thickness options of 9mm or 12mm, with lengths ranging from 6 to 9 meters. The design should be U type, with a height between 350 and 400mm measured from bottom to angle, and an angle of 23% with 100mm in length. Additionally, the bottom width should fall between 200 and 250mm. Our first order will be for a total of 1500 meters. I can provide a simple drawing to clarify our needs upon request via email. I will be in China starting next week, and I would like to know if there's an opportunity to visit your factory. Looking forward to your response!
