发明名称 Fully Welded Fence Panel And Method Of Making Same
摘要 A fully welded fence panel is disclosed that comprises a plurality of vertical pickets and a pair of horizontal metal rails. The top and bottom portions of the pickets are pressed in a mechanical or hydraulic press to create flattened surfaces and welded to the rails. The flattened surfaces may either be oriented parallel to the lengthwise direction of the metal rails to facilitate welding, or the flattened surfaces may be oriented perpendicular to the lengthwise direction of the metal rails to both facilitate welding and enable the fence panel to be racked when used as a railing. Indentations are pressed into opposite sides of the flattened surfaces at the same location and are perpendicular to the lengthwise direction of the picket to further enable the fence panel to be racked. The railing is therefore adjustable at a customer's site to change the angle between the pickets and rails and avoid the need for perfect angle measurements prior to manufacture. The end portions of the horizontal rails also include flattened surfaces that are welded to vertical posts that are positioned at opposite ends of the fence panel so that the fence panel and posts can be racked as a unit.

主权项 1. A fully welded fence panel comprising: a plurality of spaced-apart vertical metal pickets, each picket having a top and bottom portion that is flattened to substantially reduce its cross-section area as compared to the cross-section area of the remaining portion of each picket; a pair of horizontal metal rails having length; wherein the top portions of the metal pickets are welded to one of the metal rails and the bottom portions of the metal pickets are welded to the other metal rail.
