Quality standard: Zinc content per square meter has reached or exceeded 122g.

For corn circles: used as corn circle nets, the original galvanized welded wire mesh with a mesh size of 5cm*7cm or 5cm*5cm is generally used, with a wire diameter ranging from 1.8mm-2.3mm and a height ranging from 1.2m to 1.8m.

Because of the high carbon content, simple cracks occur during water quenching, so double liquid quenching (water quenching + oil cooling) is mostly used, and oil quenching is mostly used for small cross section parts. This type of steel is generally used after quenching by medium temperature tempering or normalizing or in the surface quenching state. Mainly used for manufacturing spring and wear-resistant parts.

Insulating tape, also known as electrical tape, is a commonly used tool for insulating and protecting electrical wires and cables. It is typically made of PVC material and has a pressure-sensitive adhesive on one side that allows it to adhere to various surfaces.

The control box has two main components: A specialized device that interfaces with the stop light and a sensor that detects signals from the smartphone of an approaching cyclist who has the Bike Connect app. As the cyclist rolls up to the light, the app and the sensor talk to each other, turning the light green more quickly. According to its designers, it can be put together at home with a soldering iron and $200 in parts—although that doesn’t mean that you should try to install one on a neighborhood stop light without permission and assistance from city engineers.
