A Legacy of Strength.A Promise of Quality.Driven by Trust.
Concretia Rock Products (P) Ltd. was born in 2001 in Madurai, Tamil Nadu as Royale Blue Metals (P) Limited. The company, Blue Metal In Madurai, is currently engaged in the manufacture of crushed aggregates with its own quarry that it mines with state-of-the-art technology. From humble beginnings as a simple commodity player, Concretia has grown leaps and bounds and today boasts of leading others in productive use of its capacity and one of the region’s leading players!. More than its capacity to manufacture, Concretia prides in its capability to brand what was otherwise a mundane commodity called aggregates aka blue metal. From the beginning, Concretia did not wish to be plain run of the mill and sell blue metal like a commodity, which was and still is the norm in this industry.
