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

Rust-proof 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 protection cap "Zinc Hat." The "Zinc Hat" is a cap designed for anti-corrosion protection of bolts and nuts used in sound barriers on elevated highways, amusement park equipment, solar panels, and more. In the performance confirmation test of the Zinc Hat under outdoor exposure, while the steel materials and anchor bolts without protection showed severe corrosion on all surfaces after the test, the anchor bolts covered with the Zinc Hat maintained their initial condition without any corrosion for a three-year exposure period, thanks to the sacrificial corrosion effect of zinc. [Test Types] ■ Performance confirmation test under outdoor exposure ■ Immersion test with 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

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 any adhesives or caulking materials, it is environmentally friendly and eliminates the need for cumbersome tasks. 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 that adhere to them. Naturally, corroded fastening parts 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). The current rust prevention methods have not been able to provide sufficient rust prevention effectiveness. In particular, the occurrence of rust on anchor screw parts has been a significant issue. Currently, the safety of various structures, including public buildings, is a concern. By installing the "Zinc Hat" on the fastening parts, it effectively blocks the occurrence of rust on bolt nuts through the effects of electrical corrosion protection (sacrificial corrosion action), coating corrosion protection, and inhibitor effects, thereby demonstrating outstanding corrosion protection functionality over the long term while also maintaining seismic performance. For more details, please contact us or refer to the catalog.
