In January 2017, our Zinc Hut was selected for the "Kansai Manufacturing Selection 2017" by the Kinki Bureau of Economy, Trade and Industry!

A safety revolution with the power of ions that repels rust! Reducing maintenance costs and improving seismic performance!

"Zinc Hat" is a corrosion protection cap devised by applying the electrochemical corrosion prevention effect of high-purity zinc. It can be easily and securely attached to anchor bolts and bolt nuts that support buildings and structures using a wrench or similar tool, preventing the occurrence of rust on metals through the power of ions. Additionally, it comes in a wide variety of colors to suit different applications. This fully corrosion-resistant rust prevention cap is patented and contains no harmful substances, taking the earth's environment into consideration. 【Features】 ■ Permanently and reliably prevents metal rust in various environments ■ Environmentally friendly ■ Reduces maintenance costs ■ Improves seismic performance ■ Prevents the occurrence of rust on metals through the power of ions *For more details, please refer to the PDF document or feel free to contact us.

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.

Block the occurrence of bolt rust! Excellent performance, anti-corrosion protective cap Zinc Hat.

"Zinc Hat" is a corrosion protection cap that has been researched and developed with original alloys, continuously improved, and equipped with electric corrosion protection, coating corrosion protection, and inhibitor effects. The method of installation, which involves placing the cap over the bolt, is the same as traditional rust prevention methods, but there is a significant difference in performance, providing excellent corrosion resistance over the long term. Since it can be installed simply with a wrench or spanner, there is no need to fill with grease or caulking materials, resulting in a much lower maintenance cost compared to conventional methods. 【Features】 - Sacrificial corrosion protection (electrolytic corrosion) - Coating corrosion protection - Inhibitor effect For more details, please refer to the catalog or feel free to contact us.

"Because it's an invisible place, we won't overlook it." Japan's climate is characterized by high temperatures and humidity, and particularly after typhoons and heavy rains, the conditions can be harsh for homes. It's not just the roofs and exterior walls that are affected by rain and wind. The area beneath the floor is actually the most susceptible and often overlooked point. This time, we will explain the "checkpoints for under the floor" that should be confirmed after a typhoon or heavy rain, the "responses" if abnormalities are found, and measures for preventing recurrence. [Table of Contents] ■ Why is underfloor checking necessary? ■ Checkpoints to confirm after a typhoon or heavy rain ■ Responses when damage is discovered ■ Points for preventing recurrence ■ Suggestions from Seihou Products ■ Summary Please be sure to read the [related materials] and [related links]. ↓ ↓ ↓
