美国采购需求：铝合金门、铝合金窗、推拉门、平开窗、入户门、车库门

I'm looking for information on your folding windows. Specifically, I'm interested in the materials, dimensions, and any available custom options you offer. Additionally, understanding the installation process and any warranty details would be helpful. Could you also provide me with pricing details for bulk orders and lead times for delivery? I'm eager to explore your offerings and see how they align with my project needs. If you have a catalog or any available samples, that would be great too. Looking forward to your insights and recommendations!
