I want to build an aluminum tube frame strong enough to support a 2300 lbs water tank. The dimensions of the frame would be 28 " wide, 72" long and 16 inches tall. My intention is to use 2" x 2", 1/8 wall tube for the sides, back, and vertical supports. However, on the front face i would like it open for a 'drawer step' spanning the 75 inches. My question is what kind of aluminum tube could i use for a header across that face to support its share of the load. I was considering 4" x 2" tube with 1/4 wall, installed on end, making a 4" header. Would this suffice?
Is there more information i need to provide?
Thank you to anyone looking at my inquiry
