I'm reaching out to inquire about titanium products that you offer. We're currently looking for high-quality titanium materials for our upcoming projects. Specifically, we're interested in understanding the different grades and dimensions available, as well as any specifications you may have. Additionally, it would be great to know your pricing structure, lead times for bulk orders, and any minimum order quantities that apply. Please send me details on your manufacturing capabilities and material certifications. If you have a catalog or product sheet, that would be very helpful as well. We're keen to establish a reliable partnership and would appreciate insights on your product performance and any additional services you provide, such as shipping options and after-sales support. Looking forward to your prompt response!
