Steel crash barriers on bridges face constant moisture, drainage splash and coastal salt, and repainting them at height is costly. Hot dip galvanizing protects every part with a bonded zinc coating that corrodes before the steel and covers cut edges. Coatings of about 550 g/m² to IS 4759 can last 20 to 40 years in Indian conditions. Buyers should check the coating standard, thickness certificates and fastener protection, and work with an experienced galvanizer for lasting barrier safety on bridges. To learn more:
