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