Does coal tar epoxy coating appreciably diminish the load capacity (vs bare steel) for an H-pile? I don't see where the coeff. of friction would vary much between the two. Thanks!
 
Load = axial load capacity due to skin friction.
 
skin friction will be reduced with almost any coating, including CTE
