Quartz Sand State for Infrastructure: http://indonesianindustry.com/pasir-kuarsa-untuk-infrastruktur-negeri/17 October 2015
Infrastructure development requires readiness as a means of supporting material. As a manufacturer of quartz sand from East Kalimantan, PT Anugrah Marfuah Brothers, ready to take on the role of supporting development.
