Because both of those timber piles and H-piles may have deviation above their length, the longer a degree is, the more practical it could be. Timber piles might be by far the most tough to have really plumb at start and end as a result of their irregular shape. H-piles may have a "sweep"/deviation in trueness as a result of improper dealing with and lack of aid in shipment and managing.
