Lightweight! Resin-made access hole Polyethylene access hole "EP Sleeve" for extended lifespan

All made of resin! The polyethylene pedestrian passage "EP Sleeve" improves work efficiency while promoting the longevity plan for public facilities and similar structures.

Based on the Ministry of Land, Infrastructure, Transport and Tourism's "Basic Plan for Infrastructure Longevity (Bridges, Roads, Public Housing, etc.)," we propose a dual benefit of infrastructure longevity and labor-saving at construction sites. 【Proposed Projects】 - Public facilities (public housing, infrastructure-related facilities) - Seismic-resistant buildings, etc. 【Implementation Effects】 - Longevity through non-corrosive sleeves - Improved work efficiency through labor-saving and 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 after about 10 years, potentially leading to reduced flexibility and cracking. EP sleeves contribute to the longevity of buildings and infrastructure. Additionally, the sleeve material combines "lightweight," which accelerates "efficiency" on site, with high pressure resistance and direct workability. Specifically, compared to rigid PVC pipes weighing about 53 kg/m, EP sleeves weigh about 17 kg/m, promising a significant improvement in work efficiency and labor-saving at construction sites! *For more details, please feel free to request the catalog directly via email or download it from the "EPJ Corporation" "Ipros Special Site" through the related links.
