Rust prevention cap <Zinc Hat> *Performance verification test materials provided

Rust prevention cap <Zinc Hat> *Performance verification test materials provided

We would like to introduce the performance verification results of the anti-corrosion protective cap "Zinc Hat."

We would like to introduce the results of the performance confirmation test for the anti-corrosion protective cap "Zinc Hat." The "Zinc Hat" is a cap designed for the anti-corrosion protection of bolts and nuts used in sound barriers along elevated highways, amusement park equipment, solar panels, and more. In the performance confirmation test of the Zinc Hat under outdoor exposure, it was found that while the steel materials and anchor bolts without protection showed severe corrosion across their surfaces, the anchor bolts covered with the Zinc Hat maintained their initial condition without any corrosion, thanks to the sacrificial corrosion effect of zinc, despite a three-year exposure period. [Test Types] ■ Performance confirmation test under outdoor exposure ■ Immersion test using tap water ■ Comparative confirmation test with resin caps For more details, please refer to the catalog or feel free to contact us.

Protects screws and bolts from rust! <Rust-proof cap> Zinc hat

Protects screws and bolts from rust! <Rust-proof cap> Zinc hat

The material used is equivalent to the purest zinc ingot! It protects the bolts from rust for a long time!

The "Zinc Hat ZHZ Type" is a product that prevents rust from adhering using the power of ions. Thanks to the inhibitor effect of corrosion products (white rust of zinc) formed by the corrosion of zinc, it suppresses the corrosion of iron over a long period. Since installation does not require the use of adhesives or caulking materials, it is environmentally friendly and eliminates tedious work. It is also resistant to impact and provides solid protection for the threaded parts. 【Features】 ■ Electrolytic corrosion protection effect ■ Protects bolts from rust over a long period ■ Significantly reduces maintenance costs ■ Easy installation by simply tightening ■ Using a hex socket wrench allows for a cleaner installation *For more details, please refer to the PDF document or feel free to contact us.

Rust prevention protective cap <Zinc Hat> *Patent obtained

Rust prevention protective cap <Zinc Hat> *Patent obtained

Powerful rust prevention effect! Repels rust and revolutionizes safety with the power of ions!

The Zinc Hat is a full corrosion protection cap designed by applying the excellent protective function of high-purity zinc. The fastening parts of anchor bolts and bolt nuts can develop rust and corrode due to moisture and acidic rain adhering to them. Corroded fastening parts naturally experience a decrease in strength, and when external forces such as earthquakes, typhoons, or strong winds are applied, buildings and structures are exposed to the risk of collapse. Additionally, stainless steel can also suffer from stress corrosion, crevice corrosion, and erosion depending on the processing method and usage environment (such as salt damage areas). Current rust prevention methods have not been able to provide sufficient rust prevention effects. In particular, the occurrence of rust on anchor screw parts has been a significant issue. Currently, the safety of public buildings and various structures is a concern. By installing the "Zinc Hat" on fastening parts, it effectively blocks the occurrence of rust on bolt nuts through the effects of electrochemical corrosion (sacrificial corrosion action), coating corrosion protection, and inhibitor effects, while also maintaining excellent corrosion protection functionality over the long term and preserving seismic performance. For more details, please contact us or refer to the catalog.
