尼日利亚采购需求：镀锌钢系列

I'm reaching out to inquire about products available in black color. We are looking for a range of options to consider for our upcoming project needs. It would be great if you could provide details on various materials and finishes you have in this color. If you could also share any relevant specifications and pricing information, that would help us greatly in making a decision. Additionally, we are interested in understanding the availability and lead times for these products in black. If there are different shades or variations of black, please include that info as well. We aim to establish a consistent and reliable supply chain, so your prompt response would be highly appreciated. Looking forward to your detailed offerings!
