Because coarse aggregates have been hard to find in the metropolitan area, we carefully inspect and select quality pebbles from the Honam region and Haeju of North Korea to ensure stable supply of construction materials. We can supply about 500,000㎥ of appropriately sized quality pebbles every year and process them at our independent facilities from shipping to loading /unloading, to warehousing, to delivery to safe cost.

We import and supply about 150,000㎥ of quartz sand from North Korea every year.
Imported quartz sand is widely used for industrial purposes, aquariums, landscaping, and sports fields.
