A helmet made of steel or similar material, worn to protect the top of the head, protects the head from the impact of the shock. It consists of a hat shell, a cap lining, a lower cheek belt and a back hoop. The cap shell is hemispherical, firm and smooth, and has a certain elasticity, the impact of the impact and the puncture kinetic energy are mainly borne by the cap shell. There is a certain space between the cap and the cap to buffer and disperse the instantaneous impact force so as to avoid or reduce the direct injury to the head. Impact absorption property, puncture resistance, lateral rigidity, electrical insulation and flame retardancy are the basic technical requirements of safety helmet.

Basic characteristics
Light, low hazard safety helmet with good ventilation;
Well ventilated and lightweight, providing overall comfort for wearers;

Protective role of safety helmet
When the workers head by the impact of falling objects, the use of safety helmet shell and a cap lining in an instant first impact force decomposition to the entire area of the skull, the most impact absorption structure and destruction of different sites of the safety helmet cushion structure elastic deformation, plastic deformation and allowed, to make the final effect the impact of staff head lower than 4900N, so as to protect the workers head role. The cap material of the helmet plays an important role in the overall performance of the helmet.
