For example, think of a regular pole, now shorten or lengthen it and use that as the frame of your awning. The top of the pole is designed in various shapes including points (not sharp) and rounded edges, and even a combination of both. The spears hold up the stationary awning and provide an aesthetically pleasing addition to your home, business, or restaurant.
Keep in mind, regular awnings and spear awnings share the same function. They just differ in style and look. They both use the same fabrics designed for shade structures and both are excellent additions to any home or business. It’s really up to your taste and what you want for your building and how you want it to look.
