卡塔尔采购需求：三层玻璃窗、双层玻璃窗、带玻璃的前门、三层玻璃窗、铝合金折叠门、彩色玻璃窗

I'm interested in sourcing aluminium profiles for an upcoming project and would like to get some detailed specifications and pricing info. Specifically, I'm looking for a variety of profiles that can accommodate different applications, so it would be great to know the range you offer, including dimensions, thicknesses, and finishes. Additionally, if you could provide information on minimum order quantities, lead times, and any available customization options, that would be super helpful. I'm keen to understand what you have in stock and how quickly we can move forward. Thanks in advance for your assistance!
