Regarding the supply issues of rigid polyvinyl chloride (PVC) manholes.

EPJ EPJ
[Proposal for Polyethylene Access Holes] We believe everyone is facing difficulties... “To contractors planning to use rigid PVC pipes with a diameter of 600mm” Due to the impact of the Middle East conflict on the supply of domestic PVC products, we hope that our polyethylene access holes, EP-Sleeve, can be of some assistance... * We have stock available only for the 600mm size within Tokyo. * Of course, we also offer cutting services.

Lightweight polyethylene pedestrian passage (pedestrian opening) "EP Sleeve"! Labor-saving!

High-density polyethylene pedestrian passage (pedestrian opening) "EP-Sleeve" - Lightweight, high strength, and a proposal for labor-saving! [Coming soon]

Polyethylene Personnel Access Hole (Personnel Access Port) EP-Sleeve In response to everyone's requests, we are excited to announce its upcoming release! ■ High Pressure Strength: The smooth double structure of the corrugated inner surface makes it resistant to impact and external pressure, providing 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 degradation against most chemicals. "Lightweight accelerates efficiency on site!" A material that combines high pressure strength with the lightweight that leads to direct workability. In particular, rigid PVC pipes weigh about 53 kg/m, while polyethylene sleeves weigh about 17 kg/m, showcasing an overwhelming weight difference! We guarantee a significant improvement in work efficiency at construction sites. Furthermore, it also reduces the burden on workers and lowers the risk of accidents, contributing to enhanced safety! *For details, please request a catalog from "Contact Us" or view the PDF data from "Download."

Shorten construction time with EP sleeves for construction sites!

Lightweight polyethylene personnel access EP sleeves support shortening construction timelines!

In the construction industry, shortening construction periods is a crucial issue directly linked to cost reduction and efficiency. In particular, the installation of access openings is one of the factors that affect the construction schedule due to the time and effort required. EP sleeves, being lightweight, facilitate transportation and installation, contributing to a reduction in work time. 【Usage Scenarios】 ◆ For access openings in water pit partitions of buildings and various structures! - Ensures high load-bearing performance with polyethylene pipes. - Reduces work burden with lightweight polyethylene sleeves. - Provides corrosion resistance measures in underground pits and water areas. 【Benefits of Implementation】 ◆ Proposals for labor and manpower savings! - Reduces the burden on workers - Cost reduction through shortened construction periods - Improved safety *For more details, please request a catalog through "Contact Us" or view the PDF data via "Download."

Measures for extending the lifespan of public facilities using non-corrosive polyethylene access holes "EP Sleeve".

Improvement of work efficiency with non-corrosive materials and polyethylene through-holes "EP sleeve," promoting the longevity plan for public facilities, etc.

Based on the Ministry of Land, Infrastructure, Transport and Tourism's "Basic Plan for the Longevity of Infrastructure (Bridges, Roads, Public Housing, etc.)," we aim to achieve both the longevity of infrastructure and labor-saving at construction sites as a "two birds with one stone." 【Proposed Projects】 - Public facilities (public congestion, infrastructure-related facilities, etc.) - Seismic isolation structure high-rise buildings 【Effects of Implementation】 - Longevity through non-corrosive sleeves - Improved work efficiency through labor-saving/lightweight materials - Total cost reduction (materials + construction costs) Polyethylene is a stable material that fundamentally does not use plasticizers, and its lifespan is approximately 30 to 50 years if not affected by ultraviolet rays. In contrast, PVC resin containing plasticizers begins to deteriorate in about 10 years, potentially leading to reduced flexibility and cracking. EP sleeves contribute to the longevity of construction and infrastructure. "'Lightweight' accelerates 'efficiency' on site!" A sleeve material that combines high pressure resistance and direct workability with "lightweight." In particular, compared to rigid PVC pipes weighing about 53 kg/m, EP sleeves weigh about 17 kg/m, ensuring a significant weight difference that guarantees improved work efficiency and labor-saving at construction sites. *For details, please request a catalog from "Contact Us" or view the PDF data from "Download."

Non-contact light beam touch sensor "HA-T401"

The "Energy-Saving Automatic Door Sensor HA-T401" is now available, opening only for those who want to enter without contact, whether on a busy street or in a narrow passageway!

  • NEW
  • PRODUCT

In recent years, with the outbreak of infectious diseases, there has been a demand for products that cater to "contactless operation," and this trend has extended to environments where automatic doors were previously operated by touch switches. As the automation of doors and the non-contact operation of automatic doors become more widespread, do you have any of the following concerns? ☑ Although automatic doors have been installed, they remain open due to people crossing frequently in busy areas. ☑ Touch switches have been introduced to reduce unnecessary openings and closings, but hygiene is a concern. ☑ Touch switches require regular battery replacements since they are powered. The light beam touch sensor "HA-T401" opens and closes automatic doors without contact, and its compact detection range makes it suitable for narrow passages and busy areas, contributing to energy savings and infection control. 【Benefits of Implementation】 ○ Adaptable to various door types with four spot settings, ideal for busy roads and narrow passages. ○ Energy-saving effects with two setting modes that reduce unnecessary openings and closings of automatic doors. ○ Equipped with a light beam touch function, allowing doors to open and close simply by waving a hand, ensuring hygiene. ◎ For more details, please download the catalog or contact us.
