印度尼西亚采购需求：铝合金窗，铝门，门窗，圆窗，推拉门

I'm interested in placing an order for curtain walls and would love to gather more details about your offerings. Specifically, I'm looking for information on the various styles, material options, and any customization capabilities you might have. It would also be helpful to know about your production lead times and minimum order quantities. Additionally, if you could provide insights on your pricing structure and any bulk purchase discounts, that would be great. I'd like to ensure that I choose the best option for my project, so high-quality images or product catalogs would be appreciated as well. Looking forward to your prompt response with all the relevant info!
