印度尼西亚采购需求：铝棒，铝板，铝片，铝排，铝管，铝型材

I'm reaching out to inquire about aluminium sheets for an upcoming project. We're looking for high-quality material that can meet our specific requirements in terms of thickness, dimensions, and finish. It's important for us to find a supplier who can provide consistency and reliability in their products. Could you please provide me with your product specifications, available grades, and pricing details? Additionally, if you have options for custom sizes or any certifications, I'd like to know about those as well. Timely delivery is also critical, so please include your lead times. Looking forward to your prompt response!
