克罗地亚采购需求：水泥覆盖层产品

I'm looking for detailed information on concrete canvas specifically for stream and ditch channels. Could you provide me with the pricing details? I'm particularly interested in understanding the cost per unit as well as any bulk order discounts you might offer. Additionally, it would be helpful to know what dimensions or sizes are available for the canvas. I also need to confirm whether you ship to Bosnia and Herzegovina. If so, please include information on the delivery costs to my specified address. Understanding the logistics involved would really assist in my decision-making process. Looking forward to your prompt response!
