Our business scope includes laminated steel plate business, the main agent of Japan 's gold mirror steel plate ( original import ), including NAS630 & NAS301 ( high expansion coefficient ) precipitation hardening steel plate. The product has won the pursuit of CCL / PCB customers with ultra-high hardness, extremely low surface roughness and excellent thermal conductivity. At the same time, the leveling, grinding, polishing, cutting and repairing of the pressed mirror steel plate are merged.
