TYPICAL MATERIALS FOR BOLLARD

Spheroidal Graphite Iron and Cast Steel are commonest materials for bollards. Both can be used for various applications. JIER does not recommend gray cast iron.

SG IRON

Spheroidal Graphite Iron has high resistance to corrosion and is economical choice per weight. SG Iron is more suitable for warmer environments. SG Iron bollards tend to weigh more due to a thicker cross-section. SG Iron can avoid coating damage and their surface allows for clearer cast-in details such as names and serial numbers

CAST STEEL

Cast steel copes better with cold climates. Minor repairs can be carried out by suitably qualified worker, and bollards may even be welded to existing steel structures. Regular inspection and maintenance may be required to ensure a long and trouble-free working life. Impact testing is strongly recommended for cold-weather applications.
