荷兰采购需求：钢、铝、铜、不锈钢

I'm reaching out because we're interested in making a bulk purchase of your products. Could you provide us with detailed information about the product specifications, along with your minimum order quantity (MOQ) and bulk pricing, including any available discounts? Additionally, it would be helpful to know the estimated lead time for production and your shipping options. We're looking into establishing a long-term partnership, so your prompt response would be greatly appreciated. Thanks!
