Hiya,
I'm currently constructing an outdoor fireplace. I intend to use
3x3x3/16" angle in a couple of places where I'll need a lintel. I intend
to paint it with high temp paint. Anyway, I'm wondering just what sort
of clearance I need around the steel for thermal expansion? Obviously I
need some mortar in there to hold the bricks together but just not sure of
how much of a gap around the steel I need.
Thanks very much,
jlc
