Infrastructure & Transport is a diverse field covering a wide variety of structures many of which involve huge investment and which are exposed to corrosive environments. Some examples are:
  • Bridges
  • Tidal defences - locks, dams, sluices etc.
  • Port facility structures - ship to shore cranes, container equipment, etc.
  • Waste & water treatment plants.
  • General building - steel structures in commercial, educational and government buildings, hospitals, factories, airports, railway stations and stadiums etc.
Bridges have benefited from the increases in the durability of modern coating systems developed for markets such as marine and offshore. Both long-term corrosion resistance and aesthetics have benefited, as has maintenance of less than perfectly prepared services. Bridge coating systems generally have to be approved by bodies in the country where the bridge is located. SigmaKalon has approvals (and extensive experience) in Europe like the UK, the Netherlands, Belgium, Spain, France and Asia.

The Millau viaduct in France was a recent high profile project where PPG PMC systems SigmaFast 302, SigmaFast 213 and SigmaDur 550 were chosen to provide corrosion protection. Another example is the Rion Anterion Bridge (Greece).

Steel structures
PPG Protective Coatings has a range of products that are ideal for the protection of civil structures. Key aspects are long service periods between maintenance, abrasion resistance and colour and gloss retention. Nowadays the majority of structures are prefabricated and easy in-shop application of all or part of the coating system is crucial. The SigmaFast range of products efficiently balances the needs of the contractor with those of the specifier and client – easy in-shop application, fast curing and good site performance and appearance.

PPG Protective & Marine Coatings also has a unique range of products for the refurbishment of cladding.
