智利采购需求：型钢、碳钢管、A252管、管件

I'm reaching out to request a detailed quote for seamless and welded carbon steel pipes. We're looking for options in different sizes and thicknesses to meet our project requirements. Please include information on pricing, available grades, and lead times for delivery. If you have product catalogs or relevant technical specifications, that would be helpful too. For communication, it would be great if you could send the quote via email, or feel free to reach out to me directly on WeChat. I'm eager to hear back from you soon so we can discuss this potential order further. Thanks in advance!
