The STA fused silica ceramic roller are used as transport rollers for tempering flat glass, PDP solar and silicon steel industry and so on. Tempered safety flat glass used mainly as architecture glass curtain wall, automotive industry and so on. PDP develops quickly in the years. STA fused silica roller are successfully used throughout the world in the tempering flat glass industry.
