Zibo refractory brick
1. Thermal insulation bricks fully replace commonly used decorative materials such as aluminum-plastic panels, honeycomb panels, curtain walls, etc., and are multi-functional and integrated. One construction can solve the two functional requirements of thermal insulation and decoration, and are smooth, beautiful and decorative.
