- Vibration and noise can be reduced by using high manganese steel with 4 times higher resistance to vibration than general steel
- Received favorable reviews for innovative technology that resolves noise issues between floors
On August 17, the noise-proof floor plate (PosCozy) made of high manganese steel (Mn) Z clips for apartments developed by POSCO won the Jang Young Sil Award.
About 150 related parties attended the award ceremony held in Maekyung Media Center, including First Vice-minister Nam-ki Hong of the Ministry of Science, ICT and Future Planning. POSCO Steel Solution Marketing Department's Managing Director Duk-lak Lee and principal researcher Young-dong Yu achieved the honor of receiving the awards as representatives of the company and developers.
Unlike conventional flooring that uses non-steel materials such as Styrofoam insulators and rubber buffer materials, POSCO's floor plate made of high manganese steel is developed by combining high manganese steel (Mn) Z clips - that has 4 times higher resistance to vibration than general steel - with POSCO's hot-dip galvanized steel plate, thereby being capable of reducing noise between floors. The Z-shaped high manganese steel clips absorb the vibration energy applied to the floor, preventing the noise. Test results showed that POSCO's floor plate made of high manganese steel revealed a noise level that is even lower than the top grade (43㏈ or lower lightweight impact sound, 40㏈ or lower heavyweight impact sound).
The floor plate made of high manganese steel has been jointly developed by POSCO and POSCO E&C since June 2014. After acquiring state-registered performance certification last November, POSCO is currently promoting its steel product for apartment buildings, and will increase its market share in premium housings with on-site pilot projects.
``We are currently developing technologies to apply the plate made of high manganese steel to not only floor plates but also ceilings and walls,`` said Young-dong Yu. ``We plan to expand the application scope of this product to various industrial fields beyond the domestic and overseas construction markets, such as ships and home appliances as well.``
