Zaigaist Receives Ministry Certification for 18-Story Steel Modular Apartment Technology

Steel Structure, Full Modularization of Walls and Framework
Meets the Challenging 'Three-Hour Fire Resistance' Standard

GS E&C's domestic modular housing subsidiary, Zaigaist, announced on September 15 that its self-developed steel modular apartment technology has received official recognition as an industrialized house from the Ministry of Land, Infrastructure and Transport.

Zaigaist has obtained technological certification for applying its steel modular technology to apartment buildings up to 18 stories high. Until now, the highest number of floors recognized by the Ministry of Land, Infrastructure and Transport for steel modular technology was 12 stories.

The industrialized house certification from the Ministry of Land, Infrastructure and Transport is a national accreditation system granted to modular homes that meet standards of quality, safety, and durability through standardized production processes, in accordance with the Housing Act and related housing construction regulations. This latest certification is significant as it further expands the potential for high-rise steel modular apartment buildings.

Zaigaist's steel modular apartment technology modularizes the entire structure by using steel for columns and beams, while combining materials such as concrete slabs and gypsum boards for the remaining framework, floors, walls, and ceilings. Notably, it meets the three-hour fire resistance standard, which has been a major technical challenge for commercializing high-rise modular housing, thereby increasing confidence in the safety of high-rise steel modular apartments.

Lee Yoonho, CEO of Zaigaist, stated, "With this recognition from the Ministry of Land, Infrastructure and Transport, we have established a foundation for steel modular housing to be more widely utilized in the apartment sector. Going forward, we will continue to prioritize safety and quality as we advance modular construction as a sustainable housing supply solution."

Zaigaist operates a dedicated modular production plant in Dangjin, South Chungcheong Province, and has systematized the entire process from modular design to manufacturing and construction. Through research and development, the company has developed the necessary technologies for implementing steel modular apartment buildings. It has also secured technologies to enhance modular quality, such as fire-resistant structures, floor impact noise reduction, and sound insulation performance, as well as technologies for energy efficiency.
