The thickness of the composite concrete deck slab on deck type bridges typically will be 250mm. The designer of a steel bridge has to determine the method of construction as this must be taken into account in the design of the steelwork. Weldable reinforcing steel. Bar, coil Guidelines for the Use of Steel Piling for Bridge Oct 24, 2014 · 4 4 Note 1:Corrosion Protection per Item 407 is recommended for multi-pile footings in stream environments. Note 2:If sacrificial thickness is required, a pile section other than that shown on the standards must be used. As an example, the BTIG-24 standard which covers Trestle Bents for Tx28 through Tx54 girders on a 24' roadway indicates that bents up to 20 ft tall require either 18
