The breathable holes will not significantly reduce the strength of the fiberglass safety helmet, which is ensured through scientific design and strict manufacturing processes. Firstly, during the design phase, engineers will use techniques such as finite element analysis to simulate the impact of different positions and sizes of ventilation holes on the strength of the cap shell. The final layout and size of the ventilation holes are determined to ensure the breathability effect while ensuring that the overall strength of the cap shell can still meet the relevant standard requirements.

Secondly, during the manufacturing process, the molding process of fiberglass material can strengthen the surrounding area of the ventilation holes. For example, during injection molding, reinforcement ribs are added at the edges of the ventilation holes, which are tightly combined with the glass fibers and resin of the cap body to enhance the local strength around the ventilation holes. At the same time, high-precision molds and processing techniques are used in the processing of breathable holes to avoid defects such as burrs and cracks, and to prevent stress concentration.

In addition, fiberglass safety helmets undergo strict strength testing before leaving the factory, including impact absorption performance testing, puncture resistance testing, etc. Even if there are breathable holes, any safety helmet produced according to standards can pass these tests, proving that its strength meets the requirements for safe use. Moreover, the presence of breathable holes not only does not significantly reduce strength, but also promotes air circulation and reduces discomfort caused by stuffiness in the head. Users are more willing to wear them in a standardized manner, which improves safety from another perspective.
