Founded in 1989 as a specialized construction company focusing on electrical work and plant equipment maintenance, GL Construction (formerly Kwanglim E&C) has developed over 30 years to become a trusted name in high-quality construction.
With over 30 years of expertise in constructing facilities for petrochemical, food, pharmaceutical, and advanced materials industries, GL continues to evolve and innovate in the construction sector. Building on expertise and organizational capabilities, GL has expanded its business into mechanical equipment construction and successfully completed numerous large-scale domestic and international plant projects, upholding its commitment to quality for its customers.
Since 2010, GL Construction has evolved into a comprehensive construction company capable of securing a wide range of facility and infrastructure projects. From industrial environmental facility construction required for the production of chemical products, energy generation, and environmental pollutant treatment and recycling, to the construction of commercial complexes including residential buildings, knowledge industry centers, and community facilities in urban areas, GL has expanded its footprint in the construction industry.
With multiple general construction licenses acquired, GL now spans both general and specialized construction sectors, solidifying its position as a key player in the industry.
The company continues to drive innovation not only through technological advancements but also by adopting sustainable management strategies, such as vertical integration and the launch of its own housing brand, "MODERN PALACE."
