I need a lintel over a drain, 2 courses below DPC, which is visible. The architect specified a 140mm high strength concrete lintel.
I don't want to be able to see it. I can't bury it. Can I use a steel lintel? Corrosion is a bit of a concern to me below the DPC, at the bottom of the cavity. I looked at stainless lintels, not sure if stainless is necessary and they seem rare and expensive.
What are the sensible options?
