1. A method of fabricating a cable tray comprising:
deploying a first pliable unformed rail section from a soft solid curable polymer strip;
forming the first pliable unformed rail section into a first pliable formed rail section having a definitive shape;
deploying a second pliable unformed rail section from the soft solid curable polymer strip;
forming the second pliable unformed rail section into a second pliable formed rail section having a definitive shape;
arranging the first pliable formed rail section and the second pliable formed rail section juxtaposed to each other;
transversely connecting the first pliable formed rail section and the second pliable formed rail section with a plurality of rungs to maintain spacing apart of the first and second pliable formed rail sections; and
curing the first pliable formed rail section and second pliable formed rail section to produces a first hardened rail section and a second hardened rail section connected by the plurality of rungs.
