The role of the cold-proof cotton helmet
Cotton cold-proof helmets are produced and customized according to the national standard GB2811/2019 technical standard.
When the worker's head is impacted by a falling object, the helmet shell and cap lining are used to decompose the impact force to the entire area of the cranium in an instant. The structural damage will absorb most of the impact force, so that the final impact force on the head of the personnel is reduced to below 4900N, thus protecting the head of the operator. The shell material of the helmet plays an important role in the overall resistance of the helmet.
