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.

From March 24 (Tuesday) to March 27 (Friday), 2026, RheaVita will exhibit as a conference sponsor at ISLFD, held in Fukuoka, in collaboration with Lifix Analytical. ISLFD is an international conference where researchers and engineers involved in freeze-drying and related technologies gather from around the world to exchange information and discuss research results and technological trends. Through our sponsorship at this conference, RheaVita will present the latest information on spin freeze-drying technology. At our booth, in addition to introducing the latest information about spin freeze-dryers, we will be open to consultations on a wide range of topics, including research and development, feasibility testing, scaling up, and comparisons with existing processes. We aim to create a valuable platform for information exchange for those asking questions such as "What is spin freeze-drying?", "What are the differences from conventional freeze-drying processes?", "What are the challenges of scaling up and reproducibility?", and "What new formulation and manufacturing approaches should be considered?". Additionally, individual meetings will be possible during the conference. If you contact us in advance, we will secure a meeting opportunity at a time that is convenient for you. Please be sure to stop by the RheaVita booth.
