SG, a company specializing in asphalt concrete (Ascon), announced on July 8 that it is the sole supplier of Ascon for the construction site of SK hynix's Yongin Advanced System Semiconductor Cluster. Leveraging this supply achievement, the company is also promoting the application of its eco-friendly product, Ecossteel-Ascon, at Samsung Electronics' Pyeongtaek Campus Semiconductor Plant 5 (P5), further expanding its presence in the semiconductor infrastructure market.

The SK hynix Yongin Advanced System Semiconductor Cluster is a national strategic project with a total investment of 122 trillion won and is expected to generate hundreds of trillions of won in production-induced effects, making it the largest semiconductor production base in Korea. As large-scale infrastructure construction intensifies, the stable supply of high-quality construction materials is considered a key factor.

SG has participated in core infrastructure construction from the initial stages of the project, earning recognition for its customized technical support and quality competitiveness. The company now plays an essential role in the supply chain for the creation of the semiconductor production complex.

From June 15 to 17, the company conducted an Ecossteel-Ascon test paving at the P5 site of Samsung Electronics' Pyeongtaek Campus over a three-day period. Samsung C&T's civil engineering and quality managers oversaw the site, while supervisors and SG's technical and sales personnel jointly inspected the entire process. This procedure aimed to comprehensively verify constructability, durability, and quality under real construction conditions.

The test results showed that Ecossteel-Ascon performed exceptionally well in key quality areas such as density, compaction, and stability. In particular, it was found to have approximately 4.5 times greater durability and about 2.3 times longer service life compared to standard Ascon, meeting the stringent quality requirements of large-scale semiconductor plants and advanced industrial complexes.

The product also demonstrated competitiveness in terms of cost-effectiveness. A 30-year life cycle cost (LCC) analysis showed that maintenance costs per unit area could be reduced by approximately 40.8% compared to standard Ascon, while at the Samsung Electronics P5 site, a cost reduction of about 16.1 billion won was expected.

The product's environmental performance was also confirmed. Ecossteel-Ascon achieved an 85.7% reduction in fine dust emissions compared to standard Ascon, making it a highly suitable pavement material for semiconductor manufacturing facilities, where dust control is critical due to the ultra-fine processing involved.

SG plans to leverage its sole supplier record at the SK hynix Yongin Advanced System Semiconductor Cluster and the push for application at Samsung Electronics' Pyeongtaek Campus P5 to expand its business in major domestic semiconductor and advanced industry projects.

An SG official stated, "Being the sole supplier at the SK hynix Yongin Advanced System Semiconductor Cluster site is a meaningful reference that proves our quality competitiveness and reliable supply capabilities. Having confirmed both the cost-effectiveness based on life cycle cost and our quality competitiveness through the Samsung Electronics P5 test paving, we will continue to expand the supply of our eco-friendly, high value-added products to major domestic semiconductor and advanced industry infrastructure projects to strengthen our market competitiveness."
