A launch ramp provides a conveniently portable and durable launch ramp. The launch ramp has a metal riding-plate with a concave radius-riding surface. The riding-plate has an approach end where a skateboarder enters the ramp and a launch end where the skater propels off the ramp. The riding-plate has integrally formed supports for providing sufficient support, but yet retains desirable flex in the riding surface. A stand-plate elevates the approach end at a predetermined height. The stand-plate also has integral stand-plate supports for added stability and durability. In a preferred example of the launch ramp, the launch ramp is constructed from a single sheet of aluminum-magnesium stock plate. A die press or other bending mechanism forms the single sheet into a particularly durable and stable structure. In another particular example of a launch ramp, the stand-plate may extend generally from the riding-plate at an angle that enables the stand-plate supports to provide distinct contacts with a supporting surface.
