ABSTRACT:
A fence stretcher bar manufactured from a continuously fed, hot dip galvanized bar and a method of making such a stretcher bar. In a first manufacturing phase, the bar is formed from a continuously fed round rod which is rolled into a flat bar and coiled on a mandrel. The flat bar is then continuously fed into a second phase of the operation which includes annealing, cleaning with acid, coating with zinc ammonium chloride and hot dip zinc galvanizing. The material is cut to length and the cut ends are flame-spray coated with zinc. The bar is of substantially longitudinal configuration with two cut ends substantially perpendicular to a longitudinal axis thereof and having a cross section defining two parallel planar sides and two transverse curvilinear convex surfaces.
