Ft. post choices are: <br />1) 2" x 3" x 0.044" Hollow Extrusion <br />2) All post sizes listed below.the 2" x 3" x 0,044" Hollow Section <br />Note: <br />Where job conditions dictate a post height of 10' in a 120 MPH wind zone, a 3" x 3" Roll Formed <br />COULD NOT BE used because when It Is more than 10'tall it can only support 39 SF of roof. On the <br />other hand, a 3" x 3" Fluted Post with a post height of 10'- 7" can support an area of 128 square feet of <br />area, Thus, design must satisfy both height end area requirements. <br /> <br />1 <br /> <br />-J <br />I <br /> <br />Lawrence E.
