Claresdoor is a temporary security door that can be used to prevent crimes such as break-ins, theft of materials and tools, and vandalism during construction periods. Since it allows for the setting of a custom passcode for each site, it not only enhances security during entry and exit at construction sites but also contributes to the improvement of the site's aesthetics. Initially, when it was developed, doors with security features were not as widespread, so it spread to construction sites nationwide as a pioneer in security doors. About 10 years have passed since then, and it has protected the safety and aesthetics of numerous sites, accumulating a wealth of achievements.

The board and frame are integrated, eliminating the need for screws, which is a departure from traditional indoor temporary enclosure methods. It supports "Reduce" and "Reuse," being eco-friendly with minimal industrial waste such as dust and debris generated during installation (Reduce), and is recognized as a product that can be reused at the next site (Reuse).

Our wedge-locking "Seven Scaffold" can be assembled with just one hammer and is highly regarded as a product that excels in "safety," "workability," and "durability." Its robust wedge connection allows for construction without concerns about loosening, play, or disconnection, and it offers a wide range of optional products. Thanks to its unique structure and the combination of surrounding products, it provides outstanding workability and is used in a wide range of fields, including low-rise properties such as single-family homes, mid-rise buildings like apartments, and various plants. Particularly in low-rise residential construction, which often operates under many constraints, it can flexibly adapt to narrow sites and complex building shapes. Additionally, its durability is characterized by the absence of rust due to hot-dip galvanization, allowing it to withstand over 10 years of use.
