An awning is nothing but a secondary attachment provided to the exterior walls of a building. It is also called as Overhang. Awnings are made up of different

materials, for instance canvas woven with acrylic, cotton or polyester yarn. Laminated vinyl that is stretched tightly over thin and light aluminum, iron or steel is

also used as awnings.

Awnings have a close resemblance with the configuration of truss works or planar frames.Aluminum awnings are most commonly used in cases where fabric awnings fail to

serve the purpose due to the action of external snow loads or winds loads that it cannot resist.

Awnings may be provided on a building anywhere above a door or a window or along a sidewalk. Awnings are mainly used to provide shade to the building during summers

awning. Motorized awnings are now of great demand and they run on electricity. Motorized awnings do not have any vertical supports. They are provided with retracting

lateral arms. Thus it provides an unobstructed shaded area. That is the motorized awnings are therefore more advantageous as they serve the purpose in places even when
