AFP Cast Iron Guttering

Aluminium Guttering & Cast Iron Guttering Systems

AFP offers a wide range of styles in Cast Iron guttering systems. from Victorian, to moulded Ogee, half round, deep flow half round & plain half round (all of which are available in our online shop). No other material can quiet match the character, strength, durability of a cast iron guttering system and only cast iron guttering can preserve the intentions of the original architecture of the building.


  • The physical appearance & properties of cast iron gutters will be sustained throughout it's life span as long as the proper maintenance is carried out.
  • High resistance to impact (accidental or vandalism) a major consideration for inner cities, town shopping centres, churches and schools etc.
  • Secure against most elements - including heavy snow falls, high winds and heavy rainfall
  • Strength to comfortably accommodate the weight of ladders for routine maintenance and cleaning


  • Will not rattle or creak in high winds, as long as installed correctly
  • Will not twist/click due to any temperature changes
  • Excellent sound deadening properties - no significant sound of running or dripping water


  • Cast iron gutters have aesthetic charm that simply cannot be matched by other materials
  • Retains and enhances the traditional character of the building
  • Can be painted any colour to match building
  • Many profiles to match almost any architectural style


  • Naturally durable up to 100 years, as long as general maintenance is carried out
  • Cost effective in long term, again, as long as general maintenance carried out
  • Minimal maintenance: If installed correctly to the manufacturer's recommendations, a cast iron guttering systems should require little structural maintenance throughout it’s life only periodical painting approximately every 6 years or longer (depending on climate conditions and location)
  • Profile designs have changed very little over the years. As a result of this new components can easily be integrated into existing systems, avoiding costs of complete replacement & will match up almost 100%.
  • If you ever decide to remove you cast iron guttering system it is 100% recyclable, which makes it safer for the environment.


Cast iron normally refers to grey cast iron, but also identifies a big group of ferrous alloys, which solidify with a eutectic. The colour of a cracked surface can be used to identify an alloy. White cast iron is named after its white surface when cracked due to its carbide impurities which allow cracks to pass straight through its surface. Grey cast iron is named after its grey cracked surface, which happens due to the graphite flakes that deflect a passing crack and initiate numerous fresh cracks as the material breaks up.

Cast iron tends to be very brittle & prone to crumbling, except for malleable cast irons. With its low melting point, good fluidity, cast-ability, excellent machinability, resistance to deformation, and wear resistance Cast irons have become an engineering material with a vast array of uses as it is resistant to destruction and weakening by oxidisation (rust).


Cast iron is made by re-melting pig iron, with major quantities of scrap iron and scrap steel, and taking a number of steps to remove unnecessary contaminants such as phosphorus and sulphur. Depending on the application, carbon and silicon content are reduced to the desired levels, which may be anywhere from 2 to 3.5% and 1 to 3% respectively. Other elements are then added to the melt before the final form is produced by casting.

Iron is sometimes melted in a special type of blast furnace known as a cupola, but more often melted in electric induction furnace. After melting is complete, the molten iron is poured into a holding furnace or ladle.
