Galvanized coatings provide outstanding corrosion protection for steel. Treatment of design details in accordance with good corrosion design practice will further increase the life of galvanized steel fabrications.

Many of the design requirements for good galvanizing will also ensure good drainage and optimum corrosion resistance. Fabricated assemblies should be designed to eliminate un-drained areas which will collect water and sediment in service, producing localised corrosion pockets.
