I'm reaching out to inquire about galvanized U channels. We're interested in understanding the available specifications, sizes, and any customization options you might offer. It's essential for us to ensure the channels meet our quality standards and project requirements. Additionally, we would like to know about pricing, lead times, and minimum order quantities. If you could provide a detailed quotation, including any bulk purchase discounts, that would be great. We're keen to establish a partnership and hope to receive your response soon!
