Since 2004, Kyonggi Development Co., Ltd. has been producing and supplying aggregates, a key material for the construction industry, starting its quarrying business. The company is headquartered in Wonju-si, Gangwon-do, and is represented by Lee Ki-seong. In addition to aggregates, it operates a mortar division, expanding its business in the field of basic construction materials.

"Since starting its quarrying business in 2004, Kyonggi Development has supplied aggregates, the 'rice' of the construction industry, to consumers with the highest quality for the past 18 years. As a result of not neglecting investment and research with a proactive attitude rather than staying put, the company has grown to be capable of producing over 8,500㎥ daily and 2.55 million㎥ annually. Furthermore, by acquiring and merging the mortar division in 2021, we are meeting consumer demands by improving quality and lowering prices."
