"Polymetal Super" has been uniquely molded into a wave structure by combining the strength and heat resistance of metals with the corrosion resistance, chemical resistance, and wear resistance of resins to maximize the benefits of both materials. It achieves compressive strength that cannot be obtained with resin alone, while maintaining a lightweight comparable to resin pipes. It can be widely used for drainage and collection in residential development, golf courses, grounds, forest roads, and agricultural applications. [Features] - Strength equivalent to fume pipes - Lightweight - High flow capacity - Excellent properties - Labor-saving in construction *For more details, please refer to the PDF document or feel free to contact us.

The "polyethylene sheath" is a protective tube for PC steel materials in prestressed concrete structures. Being made of polyethylene, it does not rust and can adapt to temperature changes. It is resistant to wear on the contact surface with PC steel materials and features a lower coefficient of friction compared to steel sheaths. We offer a rich lineup starting with the "Polyethylene Sheath A." Additionally, we have other options such as the small diameter type "Polyethylene Sheath," "Filler Sheath," and "Joint Sheath NP Type." 【Features】 ■ 22 years of sales performance ■ Over 1,400 bridges adopted ■ Does not rust due to polyethylene material ■ Adapts to temperature changes ■ Resistant to wear on the contact surface with PC steel materials *For more details, please refer to the PDF document or feel free to contact us.

Our company offers the "Totaku Simple Drainage Device TYPE-C," which collects leakage from the bridge deck containing salt and drains it to the vertical wall side, protecting the bridge abutments, bearings, and girders. There is no work on the bridge, and traffic regulation is not required. It is lightweight, resistant to cold, and does not corrode. Additionally, its unique V-shaped structure fits the concrete walls inside the narrow space and follows the expansion and contraction of the bridge due to temperature changes, maintaining its water collection capability. 【Features】 ■ Collects and drains leakage from expansion devices ■ Follows the expansion and contraction of the bridge with a V-shaped structure ■ Applies waterproofing material even in narrow spaces ■ Safe construction from the side of the bridge ■ Made of cold-resistant polyethylene *For more details, please refer to the PDF materials or feel free to contact us.

"TAC Mendoren" is a surface drainage material that excels in water permeability and contributes to reducing costs and construction time in civil engineering projects. It features a special three-layer structure, with a band made of recycled polyethylene shaped into a unique wave pattern, sandwiched between filter materials of highly permeable polyethylene net on both sides. It is easy to install and suitable for backfill materials and horizontal drainage materials. 【Features】 ■ Made from recycled polyethylene ■ High compressive strength ■ Excellent compressive creep characteristics ■ Outstanding water permeability ■ High water flow capacity *For more details, please refer to the PDF document or feel free to contact us.

"TAC Fluoro" is a fluorine hose suitable for the transportation of chemicals, pharmaceuticals, and food products. It is difficult for fluids to adhere to it, and it has excellent water repellency, making it easy to clean. It has excellent chemical resistance due to its low reactivity with tetrafluoro resin. We offer a lineup including "TAC Fluoro A" and "TAC Fluoro A Earth." Additionally, we have "Shime TAC," which improves pressure resistance through the adoption of a special stop structure. 【Features】 ■ Reasonable specifications ■ Easy connection ■ Smooth inner surface and highly flexible ■ Lightweight with all-resin construction ■ Suitable for both suction and delivery *For more details, please refer to the PDF document or feel free to contact us.

"Cartoi A" is a simple drainage device that improves the "corrosion environment at the ends of girders" for steel and concrete bridges. The main body is made of chemically stable polyethylene, so it remains flexible and does not become brittle even in environments as low as -20°C. Additionally, installation is only required on the underside of the bridge, eliminating the need for work on the bridge deck and traffic restrictions. 【Features】 ■ Improves the corrosion environment at girder ends ■ Suppresses humid environments ■ Resistant to cold and does not corrode ■ Fits the uneven surfaces inside the gap ■ Easy to install *For more details, please download the PDF or feel free to contact us.
