I am planning to construct a brick fire surround but am not sure what to use for a lintel over the opening. It will need to be strong enough to take three or maybe four courses of bricks over an approximately 900mm (35 1/4 inch) opening. Will a flat steel bar do, and if so what thickness and width should it be. I am imagining angle iron (steel) would be more suitable but again I am not sure of the dimensions that would be suitable. Any comments or suggestions would be greatly appreciated.
Many thanks,
Ben Edwards
