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.
Our business specializes in laminated steel plates, including the exclusive distribution of Japan's high-quality mirror steel plates, such as the NAS630 and NAS301 series. These products are renowned for their high expansion coefficient and precipitation hardening properties. The FCCL Special Pressed High Temperature Resistant Steel Plate is particularly favored by CCL/PCB customers for its superior performance in terms of hardness, surface finish, and thermal management. Additionally, we offer comprehensive services including leveling, grinding, polishing, cutting, and repair of pressed mirror steel plates
