Powder finish of galvanized guardrail is an appropriate visual alternative.

Crash screening under NCHRP Report 350 has revealed that these posts might be replaced when not in an obstacle terminal. For short stretches of damaged barrier it is most likely much better to use the very same kind blog posts as in the existing installment, yet where longer areas have to be fixed replacing messages is acceptable.
