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. The transparent coating allows for easy observation of the condition of the core wire over time, making maintenance management excellent. iR wire, which has been recognized by public testing institutions for not rusting for over 30 years, offers significant advantages in lifecycle cost compared to the conventional seven types of plating. It is used as a fence, protective mesh, basket, and embankment mat. For more details, please contact us!

The "Rust-Free Fall Prevention Net" is a highly durable fence designed to prevent cargo from falling, made with low-density polyethylene (IR) coated iron wire. The low-density polyethylene (IR) coated iron wire is resistant not only to salt damage caused by 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, debris 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, making it 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 caused by 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 coastlines 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 review 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" is a rockfall prevention system that uses low-density polyethylene (IR) coated iron wire, which 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.
