哥伦比亚采购需求：禽舍、钢结构仓库、集装箱房屋、洗手台、移动厕所

I'm reaching out to explore the availability and pricing for expandable structures and container houses, as well as any other metal structures you may offer. I'm particularly interested in understanding the various designs, dimensions, and customization options available. If you have any brochures or product catalogs, that would be helpful for my review. Additionally, I'd like to inquire about the lead times, minimum order quantities, and shipping options for these products. It would also be great to know about any ongoing promotions or discounts that might apply. Looking forward to your detailed response so we can discuss how to move forward with potential orders.
