ツカ・カナモノ Company Profile

The march of the steel bundle...

Our company has developed a "steel support" that replaces the traditional "tsuka-ki," which supports the first-floor framing of detached houses, incorporating adjustment functions and excellent durability. We have aimed for its widespread adoption under the name "Replacing Tsuka-ki with Kanamono," directly challenging the market. During the Great Hanshin-Awaji Earthquake, its functionality was proven, and we received high praise from major housing manufacturers. Recently, alongside the spread of precutting in traditional construction methods by major and mid-sized builders, we have engaged in healthy competition with other companies in the same industry, leading to a shift from the conventional 100% "tsuka-ki" to the superior strength and convenience of "steel supports." The "steel support" has reached an environment where it can be individually performance-rated, and we have obtained performance certification as the first of its kind. Additionally, as part of our new challenges, we are transitioning from "wooden beams" to "steel beams," and from wooden joists and plywood flooring to "floor panels" that incorporate insulation. We are developing a "floor base system" that allows for quick and easy installation by combining these steel beams and floor panels. Furthermore, we are working on a "seismic frame" designed to prevent the collapse of buildings and mitigate impacts during earthquakes, which eliminates the need for braces and hold-down hardware.
