Windproof umbrella is relatively technical in nature, in addition to strict requirements on the material of the ribs, and also requires very strict standards on the structural design of the umbrellas.
Windproof umbrellas can be divided into 3 types.
1. Wind-resistance: the umbrella structure won’t break down with canopy facing the direction of the wind.
2. Ventilation: double umbrella canopies to let go of the air without torturing the ribs or canopies.
3. Wind-protection: even if being blown inside out, the umbrella ribs won’t get damaged and can be recovered in gentle flaps.
boy® umbrella ribs and tension springs are made of extremely tough materials. Wind resistance ability can reach Level 10 ( Level 12 is the highest wind speed ). The good wind protection structural design ensures that even if the umbrella is blown over, there would be no damage to the umbrella structure.
