Weathering steel performs well than non-weathering in painted

Provide drip plates (also called drip tabs) to divert runoff water and protect abutments and columns from staining. Provide them on every girder because staining may occur before slab placement. Consider what the diverted water will stain—for example, do not place drip plates so close to substructure elements that wind blows diverted water onto the substructure. Drip plates over concrete riprap at bridge embankments cause stain spots on the riprap, but the alternative is widespread staining of both the abutment and riprap. If necessary, provide stainless steel drip pans to protect abutments and columns. Doing so is impractical with large tub girders and may not be necessary for plate girders with good drip plate details. Provide details that take advantage of natural drainage. Provide adequate drainage beneath overpass structures to prevent ponding and continual traffic spray from below. Communicate the importance of adequate drainage to roadway designers. Provide stiffener clips for proper ventilation and drainage. The stiffener clips shown on GNEE standard drawings SGMD, “Steel Girder Miscellaneous Details (Steel Girders and Beams),” and SBMD, “Steel Beam Miscellaneous Details,” are adequate for this purpose. Eliminate details that retain water, dirt, and other debris. Do not detail deck drains that can discharge water onto the steel, especially in regions that use de-icing chemicals. Either completely seal box or tube members or provide adequate drainage and venting to allow condensation in unsealed tubular and box sections to dissipate. See Section 2.5 for more on this subject. Use sealed expansion joints. See Section 2.1.5 for more guidance on expansion joints. Avoid any type of open joint that allows runoff to reach the steel. Specify application of an adequate protective coating to surfaces that may be subject to standing water. However, avoid details that create this situation. Specify application of an adequate protective coating to weathering steel that will be embedded in soil or gravel pockets. The coating should be one of the types used on carbon steel in the same environments, and it should extend above the interface of the embedment for several inches.
