One accommodation that has actually been tried is using zinc aluminum foil at the w-beam overlap where the zinc's galvanic action reduces the deterioration. Use thicker areas (special of the terminal) might also lengthen the life, yet maintenance needs to still include inspection of the areas and joints. Powder layer of galvanized guardrail is an acceptable visual option.

Collision testing under NCHRP Record 350 has actually shown that these articles might be replaced when not in an obstacle terminal. For brief stretches of damaged barrier it is most likely much better to use the exact same kind posts as in the existing installation, however where longer areas have to be repaired replacing messages is appropriate.
