I'm reaching out to request a detailed quote for a greenhouse designed for agricultural use. The specific dimensions we're looking for are 50 meters by 50 meters, and it's important that the structure is expandable to accommodate future growth. Please include information on the materials used, estimated lead time, and any customization options available. Additionally, I'd appreciate it if you could outline the installation process and any warranty or support services you offer. If there are variations or additional features that could enhance the greenhouse's efficiency or durability, please feel free to share those as well. Looking forward to your prompt response so we can proceed further.
