Visors can be of a variety of options.
Option one: it is a metal frame made of a 20x20, 25x25mm profile pipe sheathed with PVC polycarbonate.
The second option is a frame covered with a banner waterproof fabric with an image or logo text print, these are the so-called awnings.
The third option is completely aesthetic: this is a frame sheathed with composite material without fasteners on the front parts of the visor, such options, as a rule, are more expensive and the appearance of such visors is more presentable than other options.
But as they say for taste and color, each person has his own wishes, these products are calculated individually.
