Construction Materials

Stone and Sand

We also supply materials in the form of stone and sand to assist smelters constructions from start to finish. Stone and sand are mainly used for pile base to develop solid foundations for building smelters.

Our stones originated from the Central Sulawesi, Southeast Sulawesi and Banten Region, where we have established long-term relationships with miners and have been trusted to assist with marketing. Our Stones were specified according to their size as follows:
