乌干达采购需求：充满水的屏障

I'm looking for a quote for a water-filled barrier with dimensions of 2000mm in length and 800mm in height. Could you please provide the pricing details, including any bulk order discounts and lead times for production and delivery? Additionally, I'd appreciate information on the material specifications and any relevant certifications that the product meets. If there are variations or additional options available, feel free to share those as well. Thanks in advance for your assistance!
