iR (Ionoma polyethylene resin-coated) wire is a wire mesh that maintains its role as a fence without rusting in harsh environments (coastal areas, remote islands, volcanic regions, hot spring areas). iR wire is made of low-density polyethylene and is colorless and transparent. Its transparent coating allows for easy monitoring of the core wire's aging condition, making it excellent for maintenance management. iR wire has been recognized by public testing institutions for not rusting for over 30 years, providing significant advantages in life cycle costs compared to the traditional seven types of galvanization. It is used as fencing, protective nets, baskets, and embankment mats. For more details, please contact us!

The "Rust-Free Fall Prevention Net" is a highly durable fence designed to prevent cargo from falling, made using low-density polyethylene (IR) coated iron wire. The low-density polyethylene (IR) coated iron wire is resistant not only to salt damage from seawater and sea breezes but also to oxides contained in volcanic gases and exhaust gases, preventing corrosion over the long term and maintaining the initial strength of the wire mesh. There are numerous applications for fall prevention nets on highways, falling object prevention fences, and ball protection nets. 【Features】 ■ Maintains the initial strength of the wire mesh ■ Resistant to salt ■ Resistant to acids ■ High cost performance ■ Environmentally friendly (non-dioxin) For more details, please refer to the catalog or feel free to contact us.

The "Reinforced Basket Mat" is a coastal protection method that uses IR-coated steel wire, ideal for facilities that need to maintain strength and for locations that are difficult to maintain. IR-coated steel wire is resistant not only to salt damage from seawater and sea breezes but also to oxides contained in volcanic gases and hot spring water, preventing corrosion over the long term and maintaining the initial strength of the wire mesh. Reinforced basket mats for rivers, as well as seaside mats for coasts and leaf mats for ports, are widely used in public works. Additionally, there are construction records for backfilling warm slope embankments (concrete blocks) at Miyazaki Beach in Miyazaki Prefecture. 【Features】 ■ Resistant to salt and acid ■ High cost performance ■ Environmentally friendly (non-dioxin) ■ Obtained construction technology examination certification as a material for basket mats ■ NETIS registered (QS-120018-A) For more details, please refer to the catalog or feel free to contact us.

The "Rust-free Wire Mesh Rockfall Prevention System" uses low-density polyethylene (IR) coated iron wire for rockfall prevention and is widely adopted in public works such as national highways, prefectural roads, and within national parks. The IR coated iron wire protects the core material by completely blocking air and moisture through a strong adhesion between the IR coating and the core, significantly enhancing the durability of the wire. It is resistant not only to salt damage from seawater and sea breezes but also to oxides contained in volcanic gases and hot spring water, preventing corrosion over the long term and maintaining the initial strength of the wire mesh. 【Features】 ■ Maintains the initial strength of the wire mesh ■ Resistant to salt ■ Resistant to acids ■ High cost performance ■ Environmentally friendly (non-dioxin) For more details, please refer to the catalog or feel free to contact us.

The "IR Wire" is a wire used in cage mats and net fences, known for its excellent corrosion resistance. This product protects the core material by strongly bonding the IR coating and the core material, completely blocking air and moisture. Therefore, it can achieve the required service life even in special environments such as coastlines, remote islands, and hot spring areas. It is an environmentally friendly product made without PVC (non-dioxin), and its glossy, beautiful coating harmonizes with the surrounding landscape, maintaining aesthetic appeal. Additionally, it has excellent impact resistance and cold resistance, maintaining impact resistance at room temperature even in temperatures as low as -30°C, making it an ideal product for snowy regions. 【Features】 ■ Excellent corrosion resistance ■ Environmentally friendly ■ Harmonizes with the natural environment ■ Excellent weather resistance ■ Excellent safety *For more details, please refer to the catalog or feel free to contact us.
