蒙古采购需求：集中污水处理、污水处理厂建设、污水处理工程及产品

I'm looking for information regarding your black products. Specifically, I would like to know about the available options, their specifications, and pricing details. If there are different shades or finishes available in black, please include that info as well. Additionally, I'm interested in minimum order quantities, lead times, and any customization options you might offer. Can you send me a catalog or a datasheet for these products? This would help me make a more informed decision. Thanks!
