Before the Palram Herald 2230 7.33 x 4.56 ft. Awning, awnings were either made of fabric that instantly began to fade, or sheet tin that looked like a metal version of the fabric option. You have more choices now, and when you open your door you can enjoy the sleek, modern style of laser-cut steel arms with impact-resistant panels of thick polycarbonate acrylic. The galvanized metal arms support the acrylic panels with integrated aluminum guttering with a hidden rubber gasket that directs the water off to the sides. The twin-walled acrylic panels block out 100 percent of harmful UV rays while letting a pleasant amount of light through. The galvanized finish of the steel arms and the powder-coat on the aluminum gutter make the entire piece resistant to corrosion and weathering. All the necessary holes are pre-drilled, and the hardware you need to assemble it is included. You don't need any additional tools, but we do recommend that you get a second set of hands to install your new awning.
