Weathering steel corrodes at unpredictable rates and
corrosion will accelerate when moisture is prevalent.
Since corrosion is constantly occurring and the
weathering steel is losing cross-sectional thickness,
planning maintenance is unknown.Based on extensive studies of HDG steel in virtually
every atmospheric condition, HDG steel has over 80
years of history, and corrosion rates can easily be
estimated. More often than not, hot-dip galvanizing
protects steel beyond the expected life of a structure.
