Abstract: An elongated assembly, such as a belt or a sling, having a first end and a second end. The first and second ends are configured to accept a tensile load applied thereto. The elongated assembly comprises a first folded region audibly/visibly ruptureable at a first threshold loading condition and a second folded region audibly/visibly ruptureable at a second threshold loading condition, the first threshold loading condition being lower than the second threshold loading condition, to provide a physical indication in stages for a progressively increasing overload condition.

Abstract: A highway guardrail post comprises an elongated one-piece roll-formed metal body including a front wall defining an attachment face, a pair of opposing side walls orthogonal to the front wall, a first pair of inverted corners respectively connecting the pair of side walls to the front wall, and a second pair of inverted corners respectively extending from the pair of side walls and terminating in a pair of spaced rear edges to define a rear access opening opposite the front wall. The guardrail posts may be manufactured by roll-forming a metal sheet or coil and cutting the roll-formed metal sheet or coil into lengths.

Abstract: A prefabricated panel assembly for use in constructing a marine vessel comprises a plurality of elongated, roll-formed metal panels fixed sided to side by longitudinal weld seams. The panels include a plate portion and an angle portion adjoining the plate portion along a longitudinal primary bend, the plate portion having a generally flat panel segment, the angle portion having a web generally orthogonal to the panel segment and a flange generally parallel to the panel segment and adjoining the web along a secondary bend. The panel assembly provides a more efficient and cost-effective alternative to using individual structural steel angles welded to individual steel plate in constructing a marine vessel.

Abstract: A high strength polyester strap, preferably polyethylene terephthalate, suitable for higher load applications that typically require steel strapping. The strap is made by a process in which an extruded strand or sheet of polyester is subjected to a plurality of stretching steps with a final stretch ratio of at least 5 to 1. Raising the temperature of the strap in at least one of the stretching steps is preferred. In a preferred embodiment, the strap is surface treated to reduce the brittleness of the strap and to improve weldability. The profile of the strap is flattened as part of the surface treatment which treatment enhances the weldability of the strap.
