安哥拉采购需求：铝型材、OEM铝型材、定制铝型材、铝管、CNC铝材、铝型材工厂

I'm interested in exploring OEM and ODM pricing options for aluminum profiles specifically designed for windows and doors. We're looking for a reliable factory that can provide high-quality aluminum products tailored to our specifications. Additionally, it would be great to understand the customization capabilities you offer, including any surface treatments, colors, and finishes available. Could you please provide details on minimum order quantities, lead times, and any pricing tiers depending on order size? Our project timeline is quite tight, so timely information will be greatly appreciated. Also, if you have a catalog or samples of previous works, that would help us evaluate your offerings better. Looking forward to your prompt response!
