Benchtop panels are formed with spaced apart longitudinal edge webs and intermediate webs and spaced apart transverse edge webs and intermediate webs forming a grid with parallel top and bottom surfaces. At least one pair of longitudinal and transverse intermediate webs are closely spaced to allow subdividing the panel into plural panels by severing portions of a panel at a point between the closely spaced webs. Longitudinal bottom surface flanges provide for ease of mounting panels on a frame or table at spaced apart frame members. A connector with spaced apart legs and a connecting tab may be inserted in openings formed in gussets of adjacent panels to secure panels to each other.
