use, aluminum or steel strips, alot easiter to make, cut, mount, and alot lighter, if you wanna keep the weight down a little, cheaper materials, if I'm not mistaken for some reason I think the is 3/4 wide x 1/8 thick x 4ft long thats what you'll wanna get if your making them. Your could also play with the thickness, but I'm not sure if it comes thicker, I'm think off he top of my head but I'm pretty sure thats it.
