I'm looking for industrial hanging channels specifically designed for lighting installations, such as fluorescent fixtures commonly used in retail shops. It's important that these channels are durable and aesthetic since they'll be visible in a commercial setting. Could you provide details on your available options, including materials, sizes, and any applicable specifications? I'm interested in understanding your pricing structure and lead times for these products as well. Looking forward to your prompt response!
