PRB started its manufacturing activities in 1984 involved in the manufacturing of Wheelbarrows, Hand Trucks, Castors & Platform Truck and etc.

After its successful Public Listing in 1995, PRB had gradually diversified and expanded by moving upstream into reprocessing of steel mother coils into slitted coils / sheets (Coil Center) for the supply to Automotive, Electrical & Electronic industries. This Coil Center is a joint-venture between PRB and POSCO, the world third largest steel mill from Korea.

Meanwhile, PRB had also expanded into the manufacturing of Carbon and Stainless Steel Pipes / Hollow Sections, Steel Highway Guardrial, Steel Flat-bars, Steel Purlins, Steel Shelving and Racking for storage usage.

Today, PRB has transformed into a leading steel-processing / manufacturing Group focusing on the following main activities :
