The Protective coatings for steel bridges guide provides a summary of information to assist the bridge designer with the specification of a cost effective performance based corrosion protection system, taking into account future maintenance requirements, by using the net present value life cycle costing model. Guidance is also provided for the maintenance painting of existing steel bridges.
The guide has primarily been updated to reflect the issuing of an updated AS/NZS 2312:2014, the principal referenced standard. There are also some updates on:
- durability issues with duplex thermal sprayed metal systems (clause 3.4)
- environmental considerations (clause 5.4.3)
- weathering steel (clause 9.2).
