Galvanized Steel Culvert
Hot-dip galvanizing is the most widely used and most economical metallic coating for corrugated steel pipe. Hot-dip galvanizing protects and extends CSPs life. In addition to forming a physical barrier against corrosion, the zinc coating sacrifices itself slowly by galvanic action to protect the base steel. This sacrificial action continues as long as any zinc remains. The design life of galvanized pipeinstalled in a corrosive environmentcan be extended by coating the pipe with asphalt.
