The new "2024-2025 Comprehensive Catalog" has been released! New grating products included!

A safety walker installed at a famous ramen shop as a measure against large vehicle entrances and exits. It is structurally resistant to clogging, durable, and lightweight. The flatness feels great.

The "Safety Walker G・D" and "Safety Walker L・D" are advanced grating systems that are less prone to clogging from small stones and debris compared to traditional grating, ensuring they remain hygienic at all times. They also have an appealing appearance and are less likely to break due to their surface material structure, making them useful in various scenarios. They can be used not only as grating for on-site casting but also for various types such as drop-in, bolt-fixed, raised types, and other specially sized covers (please consult us for concrete precast products, etc.). Due to their structural design, the surface is made of a material structure that is strong against twisting and impacts from vehicle tires, making the grating very durable and ideal for preventing damage. Additionally, the design minimizes the accumulation of stones and debris on the grating itself, preserving the aesthetic appeal. Multiple slit holes are created in the "striped steel plate" or "patterned steel plate" on the surface, balancing drainage and strength. Furthermore, it has been reported that the slip resistance exceeds that of traditional models. If you frequently experience damage to grating near entrances and exits, you will likely realize that this is different from conventional grating.

[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.
