Disclosed is an enclosure made from corrugated panel and a joint channel post system to provide faster and simpler construction. The enclosure comprises a plurality of corrugated panels and joint channel members. The corrugated panels have the longitudinal edges folded over for safety and projections or lugs that protrude from the crest of one or more corrugations. The joint channels allow two or more corrugated panels to be joined together. The panels slide between two parallel flanges until the panel end abuts a stopper shoulder. The panel projections lock into a recess groove in each channel flange to provide a secure snapfit fixture for the panel in the channel. The panels can be disengaged from the channel by sliding the panel relative to the channel. Panel ends or sides that are not engaged with a channel can be covered with an end cap or foot secured by a friction or interference fit.
