Dongwha wooden floors with Nano silver surface coating technology, the latest and most advanced technology only applied in some European countries, America and Korea. The effect of this technology is to completely prevent bacteria from sticking to the surface and edges of wooden floorboards, while protecting the wooden floor from physical impacts, helping the wooden floor have the highest color durability on the market. Dongwha wooden floors have high water resistance because the wood core is pressed with high technology to reach the ideal hardness, making it very difficult for water to penetrate into the wooden floor core. Another important advantage of Dongwha wooden flooring is that the wood core is 100% pure wood pulp without additives, meeting European standards (E0 standard), environmentally friendly and not harmful to users' health.
