The MegaStructure is similar to the Super Series in that it uses hollow aluminum box beams.  These beams are extruded with keder grooves in each of the four corners, which allows the fabric to be quickly and securely fastened to the frame.  Mega Series structures are distinguished by the large dimensions of the extrusion itself - 4.75" x 13.5".   This extrusion is reinforced in all critical areas with a massive aluminum I-beam.
 
The result is truly a MegaStructure able to withstand extreme winds up to 120 miles per hour, combined with snow loads of 30 lbs. per sq ft.  This beefy structure retains its ability to be assembled and installed quickly.  It is best suited for applications of at least four months
and is ideal for semi-permanent projects.
