I'm looking to source metal fan blades with different wing configurations—specifically those with three and four wings. The sizes I'm interested in range from 15 to 20 inches. The center part should be made from iron CRC sheet metal for durability, while the wings need to be constructed from aluminum sheet metal to keep the overall weight manageable. Could you provide detailed info on your manufacturing capabilities for these items? It would be helpful to receive specifications, available finishes, and any options for customization. Additionally, please include your pricing structure and lead times for production, as well as any minimum order quantities you require. Looking forward to your prompt response with all the necessary details!
