Many factors go into choosing whether to use cable or rod, galvanized or stainless, high strength or lower strength rod materials, flexible or more rigid cable construction. Cables tend to be more efficient when lengths are long, loads are high, or the member passes several struts or clamps, as might occur in a bow truss. Rods are often a better answer when the member length is relatively short (32 feet or less), clean and smooth appearance is important, or when stiffness rather than strength is the driving design consideration.
Different rod and cable materials and different cable constructions offer a range of mechanical properties, visual effects, and inherent costs. The table and graph at right give strength and stiffness information on the variety of rod and cable choices that TriPyramid offers.
Use the buttons above to view the assemblies which correspond to the various rod and cable sizes and materials. Order by full assembly; that is, select rod or cable, plus the fittings for both ends.
