There are two angles (α and β) when the spring is put onside the profile . When the winder acts on the film, the force is transferred to the spring, according to the force theory, if α less than β,the profile will lpck the spring and the spring will move downwards; if α greater than β, the spring will move upwards. When the wind-resist SK profile is used with the spring, as α less tha β, the more wind loading, the more of force to go downwards. It is hard to collapse. On the contray, for the common profile and U shape profile, α greater than β, so the more wind loading, the more force to go upwards. It is hard to cpllapse.
