For over two decades, we have specialized in the R&D and manufacturing of metal junction boxes, distribution boxes and related products. The company has grown into a leading player in this niche market, with products exported to more than 50 countries and regions worldwide.

Our daily output reaches over 500,000 junction boxes and 5,000+ distribution boxes.
