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 electric 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, preventing the occurrence of metal rust through the power of ions. Additionally, it comes in a rich variety of colors to suit different applications. This full corrosion prevention type rust-proof 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 metal rust 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 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.

Block the occurrence of bolt rust! Exhibits outstanding functionality, anti-corrosion protective cap Zinc Hat.

"Zinc Hat" is a corrosion protection cap that has been researched and developed with original alloys, undergoing continuous improvements, and equipped with electric corrosion protection effects, coating corrosion protection effects, and inhibitor effects. The method of applying the cap over the bolt is the same as traditional rust prevention methods, but there is a significant difference in performance, providing excellent corrosion protection over the long term. It can be installed simply with a wrench or spanner, eliminating the need to fill with grease or caulking materials, resulting in a much lower maintenance cost compared to conventional methods. [Features] - Sacrificial corrosion action (electrochemical corrosion) - Coating corrosion protection - Inhibitor effect For more details, please refer to the catalog or feel free to contact us.

[To the owners of parking lots and parking lot construction companies] "I'm worried about not colliding with pedestrians when leaving the parking lot in my car..." Among vehicle entrances to parking lots, stores, residences, and factories, those particularly facing sidewalks or roadways are expected to pose risks of dangerous incidents such as collisions with pedestrians or between vehicles. To alleviate such concerns, Hotron proposes a [Departure Warning Sensor] that detects vehicle departures using various sensors and alerts the surroundings with LED lights and buzzers. The device consists of a simple configuration of "Sensor" + "Controller" + "Switching Power Supply (24V)" + "LED Rotating Light." *Please note that a separate control panel including the controller and switching power supply (24V) is required when using the departure warning system. *We kindly ask customers to arrange for the switching power supply (24V), LED rotating light, control panel, circuit breakers, etc. Since it can be retrofitted, it can also be used for existing parking lot entrances. We hope this will contribute to safer vehicle passage for everyone. ◎ For more details, please contact us or download the catalog.
