The long piece needs to be about 6 wider than your window.
Attaching awning material to metal frame.
The metal covering s tendency to buckle and flex makes it unsuitable to hold the weight of an awning.
Except for some commercial applications metal buildings with no backing material are typically light gauge.
In this case install an appropriate cross brace between the metal studs in the building s structure.
I started by cutting my long back piece that will attach to the wall over the window and the two side pieces.
Fasten the awning bar to the brackets.
Generally speaking most people have few problems attaching awning frames.
Before attaching an awning frame to a building or a wall check to make sure the building is strong enough to support the weight of the awning.
Make sure the awning frame is not obstructing access to the building or any of the utilities.
Attach the hardware through the brackets and over the awning bar to hold it in place.
Diy corrugated metal awning.
Now you can cut your corrugated metal to fit the frame and attach with self tapping screws.
I built the awnings with 2 3 boards and a sheet of corrugated metal.
If you are putting the fabric on a curved frame clamp both back edges of fabric as well as the center front of the fabric to the frame.
Make sure the hardware you use is tight and that your awning does not wiggle around.
Pull the awning cover into place on the frame.
Line up the corner seams of the awning fabric with the corners of the awning frame and clamp in place with spring clamps.
