Cast iron or steel fire bowl
Updated: 21 October 2026
The title says cast iron, and you still do not know what will arrive. On amazon.co.uk the same heading covers a 4.5 kg painted bowl and an 11.6 kg bowl that reviewers call thick. This page uses the kilograms and the UK reviews in the [fire bowls comparison](/hub/outdoor-fire-pits/fire-bowls), checked on 19 October 2026. Peter F. did not send metal to a lab.

What the two metals are supposed to do
Cast iron, when it really is a thick casting, is heavy and slow. It holds warmth after the flame has dropped. A specialist 850 mm bowl sold as cast iron, outside this set, was 24 kg on 20 October 2026. Steel sheet is usually lighter at the same diameter, heats faster, and a thin wall cools faster. It also rusts once the coating has burned off. Neither metal is smokeless, and neither belongs on decking.
You can see the difference in a kilogram figure a person could lift, and in reviews that say thick, thin, or stamped as steel. Paint is not a metal test. If you want the heat-holding mass, buy the listing whose weight and reviews describe a heavy bowl. If you want a light bowl, buy the listing that says steel. Those jobs are on best fire bowl UK.
Where this set disagrees with its own title
The Harbour 56 cm is the clearest miss. It is about £33.99 and the weight field says 4.5 kg. The title says cast iron. The material field says metal. Several UK reviews say thin light metal. At 4.5 kg, treat it as painted light metal.
The Harbour 60 cm prints 18.3 kg at about £89.98. UK reviews include hefty steel, and one says it is stamped as steel. The kilograms support heavy. They do not settle the word iron. The Harbour 100 cm reviews describe pressed steel, including about 3.5 mm, and the weight field prints 23000 kg, which is not a mass. Ignore it. The Hammer & Tongs bowl is 10.5 kg, and a reviewer put the wall at about 2 mm. That is not a thick casting.
Painted steel, pre-rusted steel, and mesh
The Yaheetech states steel and high-temperature paint, at 54 cm and 3.3 kg. The words match a light bowl, and it lists a log grate. The Nicoman bullets say pre-rusted steel on purpose, 15 kg at 70 cm and 25 kg at 91 cm. Pre-rusted steel is not a corten certificate. Both files are 5.0 from one review. The 70 cm review says the bowl is too low to use as a fire.
Mesh is not a bowl wall. The TuDou is folding 304 stainless mesh at a stated 600 g. It does not hold ash, and it does not hold heat the way an 11.6 kg dish does. The HYCHIKA BR58 is 3.11 kg, with a review that calls the metal extremely thin. The Baverta listing says iron in one field and steel in a bullet. When the page cannot agree with itself, you do not have a metal to choose.
What rust does and does not prove
Surface rust is what happens when a fire burns the coating off. The British Ironwork Centre's care note says outdoor iron and steel rust after heat removes the paint, and that ash is acidic, so you empty it. Rust on its own is not a failed bowl. A thin wall is a different fault. The 4.5 kg Harbour 56 cm and the 2 mm Hammer & Tongs comment are thickness problems.
Do not shock a hot bowl with a large volume of cold water. The same care note says that can crack metal. None of this certifies the Esschert FF44 as cast iron. At 11.6 kg, with thick and solid used by buyers, it is the strongest iron-like record in this set. It is still a description, not a mill certificate. If the title says cast iron and the bowl is 4.5 kg with thin-metal reviews, buy it as light steel, or buy the Yaheetech that says steel.
Common questions
Is cast iron always heavier?
A thick casting is heavy for its size. A title that says cast iron is not. In this set, 4.5 kg at 56 cm comes with reviews that deny cast iron, and 11.6 kg on the Esschert comes with reviews that say thick. The Harbour 60 cm at 18.3 kg is heavier again and is described as steel by at least one buyer. If the kilograms and the review text conflict with the heading, the kilograms and the reviews outrank it.
Will steel rust through?
Bare steel rusts outdoors, and a fire strips paint, so a light painted bowl will show rust after use. Whether it rusts through depends on thickness and on whether you leave wet ash in it. A 3 kg bowl has less metal to lose than an 11.6 kg dish. Stainless mesh rusts more slowly and still is not a solid wall. Empty the ash when the bowl is cold, and do not read the first orange patch as a defect that the listing promised to avoid.
Is pre-rusted steel the same as corten?
Not on the evidence in these listings. The Nicoman bullets say pre-rusted steel. They do not show a corten grade, and we are not giving that finish a number of years. Pre-rusted means the rust colour is intentional. It does not mean the bowl has been tested as a fire. The single review on the 70 cm model calls the height too low. Check that height before you expect a fire you can sit around.
Does paint survive the first fire?
Expect the coating in the flame path to burn, blister, or smoke off on the first proper fire. High-temperature paint on the Yaheetech is a listing claim about the coating, not a claim that the bowl stays showroom-fresh. Reviewers of painted Harbour bowls treat the loss of lacquer, and the rust that follows, as normal. Cure a heavy bowl with a small fire first if you are following specialist iron-bowl practice. Do not stand over it indoors while any coating burns.
Which listings in this set are disputed?
The three Harbour bowls are the dispute. The 56 cm is 4.5 kg with thin-metal reviews against a cast-iron title. The 60 cm is 18.3 kg with a steel-stamp review against a cast-iron field. The 100 cm has pressed-steel reviews and a 23000 kg print. Hammer & Tongs still has a 2 mm wall comment. The Yaheetech states steel, the TuDou states mesh, and the Nicoman states pre-rusted steel. Dispute means the title and the evidence diverge.
