Cornel 2-Column Bare Metal Lacquer Products
Frequently Asked Questions
Why choose the 2 column Bare Metal Lacquer model over deeper versions for a hallway?
The 2 column model has a slim depth of just 65mm which combined with the wall brackets results in a total projection of under 100mm making it the perfect choice for narrow hallways where you want the striking industrial aesthetic of raw steel without the radiator intruding into the walking space.
How does the clear lacquer affect the heat output of the 2 column radiator?
The clear lacquer is a very thin protective layer that has negligible impact on thermal emissivity so the heat output of the Bare Metal Lacquer model is effectively the same as the painted versions meaning you can rely on the standard BTU ratings for sizing.
Does the 2 column design provide enough heat for a high ceilinged room?
While the 2 column design is efficient its slim profile means it has less surface area than 3 or 4 column models so for large high ceilinged rooms you may need to specify a taller (e.g. 1800mm) or much wider 2 column radiator to generate sufficient BTUs compared to a deeper multi column alternative.
Can I see the weld marks on the 2 column Bare Metal Lacquer radiator?
Yes the 2 column model features visible laser weld lines where the two vertical tubes join the top and bottom headers and because the lacquer is clear these manufacturing details are prominently displayed as a key part of the product's authentic industrial character.
Is the 2 column Bare Metal Lacquer radiator suitable for a bathroom installation?
You can install it in a bathroom but you must be aware that the clear lacquer over raw steel is less forgiving of high humidity than a thick powder coat so excellent ventilation is essential and you should avoid placing it right next to a shower where it will be constantly splashed.
What cleaning method ensures the longevity of the lacquer on this specific model?
To maintain the lacquer seal you should simply dust the radiator with a soft dry cloth and occasionally wipe it with a damp cloth using mild soapy water never use abrasive cleaners or harsh chemicals as degrading the lacquer will expose the raw steel to rapid oxidation.
Do I need special valves to match the raw steel finish?
Standard chrome valves can look a bit too shiny against the raw industrial steel so it is highly recommended to use "Pewter" or "Satin Nickel" valves which have a muted metallic tone that perfectly complements the grey and bronze hues of the bare metal finish.
How do I calculate the pipe centres for the 2 column model?
The pipe centres are calculated by taking the total width of the radiator and adding the valve dimension (typically 80-90mm) the 2 column model's side connections are standard 1 2 inch BSP so the measurement process is the same as for any standard radiator.
Is the 10 year guarantee affected if the lacquer is scratched?
The guarantee covers manufacturing faults like leaks but if you scratch the lacquer deep enough to expose the metal rust will form which is not covered by the warranty so it is vital to touch up any deep scratches immediately with a clear metal lacquer or varnish.
Why is the 2 column model lighter to install than the 3 or 4 column versions?
The 2 column radiator contains significantly less steel and holds less water volume than the deeper models making it much lighter to lift and easier to mount on stud walls where weight loading might be a concern for the heavier 3 or 4 column versions.
