英国采购需求：家禽养殖场、钢结构仓库、集装箱房屋、洗手站、移动厕所

I'm interested in exploring your range of expandable containers. Could you provide me with more detailed specifications, including dimensions, materials used, and any customization options available? Additionally, I would like to understand your pricing structure and minimum order quantities for these products. Please let me know about the lead times for production and shipping, as well as any bulk order discounts you might offer. It would also be helpful to receive information about previous client projects or any certifications the products hold. Looking forward to your prompt response so we can potentially move forward with an order soon.
