We handle "stainless steel pools." They are highly resistant to external pressures such as earthquakes and ground subsidence, as well as water pressure, and are extremely long-lasting due to their resistance to rust and corrosion. For pool sites, if there is little difference in height with the drainage ditch, above-ground or rooftop types are suitable. If there is sufficient drainage height, a semi-underground type is appropriate, and for locations that require a wide poolside (such as resorts and leisure areas), an embedded type is ideal. 【Features】 ■ Resistant to rust and corrosion ■ Long lifespan ■ High waterproofing ■ Can be installed in various locations, including indoors and on rooftops ■ Smooth surface with minimal water stains *For more details, please refer to the PDF materials or feel free to contact us.

This product is a cover thickness measurement tool for rebar inspection and photo management. It can be used in hard-to-reach areas where setting a scale (measuring tape) is difficult. Additionally, the cover thickness of the rebar is clearly visible, allowing for easy solo photography, making it easier to keep records. 【Features】 ■ Made of plastic ■ Compressive strength of over 2000N ■ Can be modified for slab cover measurement scales ■ Optional accessories available (sold separately) *For more details, please refer to the PDF document or feel free to contact us.

"Safety Fit Grating" is a grating designed from the perspective of users and installers, born from over 100 on-site construction achievements. It is soft and does not feel cold, making it suitable for use as a drain cover with bare feet. Thanks to its connection method that allows for easy length adjustment, it is quick to install and easy for anyone to understand. When shortened and laid down, it fits perfectly into the receiving frame. 【Features】 ■ Easy to install and adjust ■ Suitable for bathrooms and pools ■ Spring connection prevents gaps ■ Resistant to dirt and hygienic ■ Reduces work time *For more details, please refer to the PDF document or feel free to contact us.

Concrete spacers, widely used in the civil engineering field, often fall off from rebar after installation or during concrete pouring, failing to perform their function as spacers. Additionally, their heavy weight and fragility have raised concerns about workability issues and the risk of falling accidents. To address these shortcomings, a collaboration between Kinki University’s Faculty of Industrial Science and Technology, the Fukuoka Industrial Technology Center, and Chuo Sangyo Co., Ltd. has led to the development of the star-shaped plastic spacer "Plas-Star G," which is highly effective in suppressing crack formation in concrete, starting from 2005. This product is registered with NETIS (QS-080024-V). 【Features】 - The product design is based on thermal stress and drying shrinkage stress analysis, avoiding stress concentration on the concrete surface. - The effects of thermal expansion and drying shrinkage are comparable to those of mortar and concrete spacers. - Test results from temperature load tests show that the impact on cracking and adhesion to concrete is also comparable. - Regarding cracking, it is reduced to less than half compared to donut-shaped plastic spacers (below 85% at temperatures below 40°C). - The degree of filling of the concrete is significantly improved.
