Abstract: A sheet metal fence of very few different components. A bottom fence panel assembly includes a corrugated panel with a lateral stiffener compression fit to each corrugated panel edge. A top panel assembly is identically formed. The ends of the top and bottom panel assemblies are inserted into respective channel-shaped half-posts that are anchored in the ground. Eight fasteners fasten the panel assemblies via only two of the lateral supports, to the half-posts, to thus provide a fence section with only eight total components, with three being different.

Abstract: A corrugating machine has a top reel and a bottom reel, each with roller bars that intermesh with each other so that sheet metal that is passed therebetween can be corrugated in a uniform manner. The roller bars deform the sheet stock into the corrugations, but prevent marring of the precoated finish on the sheet metal.

Abstract: An economical metal fence includes a lateral channel frame structure and corrugated panels that fit together without requiring fasteners. The lateral channel structures firmly engage the corrugated panels for support, while the lateral channel structures are held within vertical channels with very few fasteners. The lateral channel structures and associated corrugated panels do not bottom out laterally against the vertical channels. In this manner, the spacing between fence posts is not critical.
