冰岛采购需求：黑色钢板、金属板、碳钢板、碳钢板、碳钢板、金属板

I'm interested in knowing the pricing details for your products when ordered in small batches. Could you provide me with your cost breakdown, including any minimum order quantities and possible discounts for larger orders? Additionally, it would be helpful to understand the lead times for production and shipping. I'm looking to evaluate options for future purchases, so any information on customization options and product variations would also be appreciated. Thanks in advance for your help!
