One accommodation that has actually been tried is making use of zinc foil at the w-beam overlap where the zinc's galvanic activity reduces the deterioration. Use thicker areas (aside from the terminal) may likewise lengthen the life, however upkeep needs to still this contact form consist of inspection of the sections and joints. Powder finish of galvanized guardrail is an appropriate visual alternative.

Crash screening under NCHRP Record 350 has actually shown that these messages might be replaced when not in an obstacle terminal. For brief stretches of damaged barrier it is most likely better to use the same kind posts as in the existing installment, yet where longer sections need to be fixed replacing posts is acceptable.
