Hard Landscaping - Seaside Special Cast Iron v Polyurethane
Due to a number of problems relating to the long term durability of Polyurethane, CIS Street Furniture have seen some clients move back to the more traditional, cast iron street furniture. Castable polymers have been used in the manufacture of street furniture since the early 90’s (a relatively short space of time) especially when compared to cast iron products. Polymers have little strength when used alone and most rely on a steel core for strength. In some cases this core can expand due to heat or corrosion and split the polymer coating. Once split there is little that can be done to repair the post in situ leading to costly replacement of the unit.
Cast Iron has been used in the manufacture of street furniture for hundreds of years, it is durable, strong, environmentally friendly and easily replicates complex geometrical shapes. On going development over this time has given cast iron unparalleled uses for this very versatile material. CIS Street Furniture cast iron posts have been used extensively in the harsh and aggressive sea front environment on the Isle of Man. One project to use this is the Peel Marina scheme. CIS provided over 300 cast iron, 250 series posts, all supplied with a marine specification paint. The posts were chosen for their simplicity of design and adaptability, all being available in many differing designs, all with common rail heights.
Why buy imitation cast iron when you can have the real thing? Maintenance? Durability? Longevity? If you are thinking “That’s why I buy plastic!” did you know that: Even with paint treatment cast iron will last 100 years outdoors Cast iron is infinitely recyclable Cast iron cannot be set on fire Cast iron cannot be carved or cut
Cast iron can be treated with zinc (giving extremely high levels of corrosion protection)
It may be noted that iron is the ultimate recyclable material. Iron can be recycled ad infinitum, unlike many materials. Some polymers can only be recycled a limited number of times, some not at all. A percentage of virgin material may even need to be added to them in the manufacturing process. Also, iron does not give off any toxic fumes, unlike many plastics which decompose on recycling to give off some very harmful by-products which can include cyanide and sulphor dioxide.
