I'm looking for a sliding door with a length of 12 feet. It would be great if you could provide some details about the materials you use, any customization options available, and the lead time for production. Additionally, I'd like to know about the installation process and whether you offer any warranties or after-sales support. If you have any catalogs or brochures that showcase your sliding doors, please send them my way. I'm particularly interested in any features that enhance durability, energy efficiency, and aesthetics. Looking forward to your prompt response with pricing information and any recommendations you might have based on industry standards.
