英国采购需求：铝，铝板

I'm looking to purchase aluminum chequer plates, specifically in a certain thickness and grade. The dimensions I'm interested in are fairly large, around 9200mm by 2500mm. Could you please provide quotes for bulk orders of 50, 100, and 150 sheets? I'm particularly interested in the FOB pricing for these quantities, as it will help in comparing costs effectively. Additionally, if you could include information regarding lead times, payment terms, and any available discounts for larger orders, that would be greatly appreciated. I'm looking forward to your prompt response so we can potentially move forward with this procurement. Thank you!
