There are thousands of MILES of layed-by steel pipe in the NatGas industry. 90 feet long and epoxy coated

Cold be 30ft or 45 ft length for ease of transport on a flat bet truck.

High tensile steel 6 inches and more in diameter...those 45 ft lengths should be just great....set 15 ft in cement.

Or spare train tracks would work OK

Used in Australia ..called a Stobie pole...indestructable:

Stobie pole A Stobie pole is a power line pole made of two steel joists held apart by a slab of concrete. It was invented by Adelaide Electric Supply Company engineer James Cyril Stobie. Stobie used materials easily at hand due to the shortage of suitably long, strong, straight and termite-resistant timber in South Australia.
