美国采购需求：家禽养殖场、钢结构仓库、集装箱房屋、洗手站、移动厕所

I'm reaching out to dive deeper into your prefab building offerings. I'm particularly interested in understanding your pricing structure, including any bulk order discounts or seasonal promotions that might be available. Additionally, I'd like to know more about the range of specifications for your products, such as materials used, customizable features, and energy efficiency ratings. Could you also share information on the current availability and lead times for orders? This would help in planning our procurement process effectively. If there are different models or configurations, providing a catalog or a link to your website would be appreciated for a comprehensive view of what you offer. Looking forward to your detailed response!
