巴西采购需求：钢结构建筑、营地房屋、预制房屋、20英尺集装箱房屋、预制集装箱房屋、预制钢结构

I'm interested in receiving a detailed quotation for several items I need for an upcoming project. Specifically, I'm looking for options regarding housing solutions, restroom facilities, and storage units. It's important that the products are durable and suitable for both indoor and outdoor use, as versatility is key for our application. Could you also provide information on the available sizes, materials, and any customization options? Additionally, I'd like to know about lead times for delivery and any bulk purchasing discounts you may offer. Your prompt reply would be appreciated, as we aim to finalize our procurement decision soon. Thanks!
