Corrugated Steel Structure (CSS), which was applied in North America in the early 1900s and has been installed in more than 1,000,000 places worldwide, has been in service since 1996, 100 years later, in Korea with POSCO, Korea Expressway Corporation, Seoul National University, Hanyang University, etc. It has been applied to the domestic market through commercialization research by specialized companies. Based on this, since the 2000s, it has been widely applied to road crossing passages, waterways and local small rivers, animal movement ecological passages, and Piam tunnels. Based on the advantages and economic feasibility of minimizing the existing vehicle traffic control during construction, it is a universal new construction method along with the existing reinforced concrete construction method. About 5000 corrugated steel plate structures have been installed and operated in Korea for 20 years.
However, regarding the various advantages of the construction method and the rapidly occurring demand, in the beginning, detailed explanations of the national design standards and specifications were insufficient. Problems such as deformation of the corrugated steel sheet occurred intermittently due to the lack of understanding of the backfill material and backfill compaction, which are the most important factors in
To improve this, ChungAmEnC has continuously improved and supplemented related standards through R&D with various related organizations, and based on domestic and foreign failure cases, provides optimized design solutions in advance for possible problems during actual construction. Optimized solutions include Virtual Construction: a three-dimensional system for step-by-step forecasting processes. (BIM LoD: 350 / Tekla, Trimble) and 3D Scanning (Leica P30 System, Cyclone ) Minimize errors that may occur at each construction stage I did. In addition, by providing 3D FEM, 3D printing and landscape design solutions, we will do our best to become a company that continuously develops and provides the world's best solutions that overcome the uncertainty of design and construction anxiety that customers have felt.
History of CSS
In 1896, an American civil engineer James. H. Watson and Starting with Stanley Simpson's patent, it was applied to small drainage channels in North America until the 1930s, and by the late 1900s, the maximum span was applied up to 11m and expanded to small bridges, passageways, and military facilities (ammunition depots). Since the 2000s, the span has been extended to 23m and applied to ecological tunnels, mine stockpiles, reclaim tunnels, and military facilities (hangars). 2014-2016 R&D and commercialization of extra-corrugated corrugated steel sheet (EXSCor) of Cheongam EnC With success, the maximum span was extended to 40m. It satisfies the maximum loads of CAT 797F (about 620 tons), EURO LM71, mine trucks, which could not be applied in the past with respect to live loading along with the expansion of span, so that it is economical, stable, and workable than concrete structures in multi-step processes. has enough competitiveness. In addition, extra corrugated steel sheet (EXSCor) is listed as a construction method and product according to design standards in Korea (KDS, KCS) as well as AASHTO LRFD and ASTM A796M in the United States.

Corrugated Steel Sheet Building & Storage Application
Corrugated steel sheet structures are highly durable and recyclable because they do not deform even when exposed to UV rays or water. As a structure that does not require maintenance (waterproofing, painting), its appearance does not change significantly even after several years. The advantages of corrugated steel sheet construction are economical efficiency and short construction period. Since the structure is completed by bolting on site using steel sheets manufactured in the factory, quality control is excellent and construction is easy. In addition, it has the function of protecting the interior from the external environment without the need for a separate finishing material.

Solution
Corrugated steel sheet structures are structures that exist without internal pillars, and after installing the corrugated steel sheet external walls, it is easy to configure the interior space to meet the needs of users. A unique design is possible by expressing the three-dimensional effect of Co-Work with a domestic architectural design company (Playing Room, Myongji, Hybrid Center, Dong-gu, Incheon) and a Japanese architectural design company through Co-Work with a Japanese architectural design company, through very detailed drawing consultation, for the Coin Laundry franchise building in Nagoya, Japan, as well as factories and golf course resorts in Osaka area Installed.
