In public construction civil engineering sites, there are many instances where sheets are used as common temporary facilities, such as construction roads, access roads, heavy machinery work yards, material storage areas, and worker pathways. Traditionally, steel plates were common, but due to their weight, transportation and installation can be cumbersome. Hyper CLT sheets are civil engineering materials made from wooden CLT for civil engineering use. The 5×10 sheet weighs about 230 kg, and the 5×20 sheet weighs about 460 kg, making them lightweight and easy to transport, install, and remove, even with small machinery. They can be widely utilized for temporary roads, heavy machinery scaffolding, pathways within the site, and protection of material storage in public works. Since they are made of wood, they also contribute to environmental aspects such as reducing summer heat reflection, lowering noise, and fixing CO2. They can simultaneously address construction efficiency, safety measures, and environmental considerations, making them effective for innovative proposals in public works. Furthermore, they improve transportation efficiency and reduce labor in site operations as an alternative to steel plates. Hyper CLT sheets are registered technology with the Ministry of Land, Infrastructure, Transport and Tourism under NETIS "TH-250021-A." They are recommended for companies considering civil engineering, civil engineering use, and civil engineering CLT. Feel free to request materials or consult about implementation. They are temporary materials that also help improve site evaluations in public works. Please consider them.

We have released a new video on our company’s YouTube channel. The theme of this video is "The World of Amino Acid-Based Shampoos." Amino acid-based shampoos have become popular in recent years, but the lather, feel, and finish can vary greatly depending on the cleansing ingredients used. In this video, we clearly explain the changes in user experience based on the differences in cleansing ingredients by comparing two types of amino acid-based shampoos. We hope you can use this as a hint for developing original shampoos and differentiation.
