ABSTRACT:
A glazing panel system is provided using retention clips formed of folded sheet metal having a top flange for engaging and retaining a pair of glazing panel ends against uplift forces generated by high velocity winds flowing across the glazing panels. The preferred one piece retention clip has a two ply central web which is formed on the retention clip to be positioned at a seam between adjacent glazing panels and these plies may be welded together to increase the strength of the central web. This top flange is strengthened to resist bending of its right or left flange section by raised portions extending normal to the fold lines that join the respective top flange sections to the top of the central web. The preferred retention clip also is formed with spot welds to join the two plies of the central web.
