A few common fabrications where drainage is important are gusset plates, stiffeners, end-plates, and bracing. Following these best design practices will help ensure the highest quality coatings:
• Where gusset plates are used, generously cropped corners provide for free drainage. When cropping gusset plates is not possible, holes at least 112-inch (13 mm) in diameter must be placed in the plates as close to the corners as possible (Figure 1).
corners as possible (Figure 1).

Alternatively, holes at least 112-inch (13 mm) in diameter can be placed in the web within 1I4-inch (6 mm) of the
end-plate. To facilitate drainage, end-plates should have holes placed as close to interior corners as
possible (Figure 9).

Atypical coatings produced from reactive steels exhibit different coating characteristics than a typical galvanized coating such as:
• Levels of carbon less than 0.25%, phosphorus less than 0.04%, or manganese less than 1.35% are beneficial
