- Frame construction accessories
- Piping materials (plastic pipes)
Production will start" Polyethylene sleeve / access hole (access port) "EP-Sleeve
Polyethylene Human Passage (Human Passage Opening) EP-Sleeve ■ High Pressure Resistance: Due to its smooth double structure with a corrugated inner surface, it is strong against impacts and external pressure, possessing excellent flat strength. ■ Lightweight Material: Compared to rigid PVC pipes, it is lightweight. It enhances transportation and work efficiency, contributing to "labor-saving" at construction sites. ■ Rust Resistant: Made of high-density polyethylene, it is safe and secure for installation in water areas! ■ Cold and Chemical Resistant: Compared to rigid PVC pipes, it is suitable for installation in extremely cold regions and shows no deterioration against most chemicals. The polyethylene sleeve "accelerates the 'efficiency' of the site with its 'lightweight'!" A material that combines high pressure strength with "lightweight," which leads to direct construction usability. In particular, while rigid PVC pipes weigh about 53 kg/m, the polyethylene sleeve weighs about 17 kg/m, showcasing an overwhelming weight difference! We guarantee a definite improvement in work efficiency at construction sites. Furthermore, it also contributes to reducing the burden on workers and lowering accident risks, enhancing safety!
The energy applied to the pipe is released due to its flexibility.

We have prepared BIM-compatible data for the rooftop multipurpose unit "Hatokotto."
"HATOCOT," which has been in use for over 30 years since its release, is widely applicable not only for new constructions but also for renovations and upgrades of air conditioning systems, having been adopted in over 15,000 sites. By modularizing pigeon loft construction, we provide numerous benefits such as shortened construction periods, labor savings, reduced rooftop weight, and improved maintenance during inspections and repairs. In response to the recent trend of applying BIM in the construction industry, we have prepared BIM-compatible family data for "HATOCOT" to ensure its adoption in an even wider range of sites. By utilizing the family data, tasks such as cost estimation and weight calculations during the design phase become easier, enabling further improvements in productivity and labor savings. *For BIM data, please contact us or download it from the official website (membership registration required).

[New Construction Case Studies] Gas Pipe Restoration Work
We have uploaded a new construction case study for the high cement content soil improvement agent MT series. This case involves the removal of mud during the excavation of a shaft for gas pipe restoration work. Please take a look at the link below. The project is for the restoration of gas pipes buried underground. During the excavation of the shaft, groundwater was encountered at depths of 10 to 30 meters, causing mud and muddy water to hinder the construction. Additionally, the temporary storage yard was small, necessitating the immediate removal of the mud. In response, MT-1 was adopted, and this product was added to the mud mixed with quality soil for improvement. The improved soil was immediately transported to a treatment plant located about 15 kilometers away. *For more details, please refer to the PDF document or feel free to contact us.*
