Making concrete stair treads ?
Has anyone ever made concrete stair treads ?
I am wondering if this is an option instead of using timber treads for some stairs I am putting in down at the pool. the stairs will be exposed to the weather, from concrete slab around the pool up onto a raised pergola deck. I would try to make them match the exposed aggregate slab at the pool.
I have ordered a pair of galvanised steel stringers, the treads would need to be about 1200x250x50mm, stringers about 1 meter apart.
I am thinking about using 2 lengths of angle iron with stainless bolts welded for attaching the tread to the stringers, I am thinking about 5 lengths of 1/2" rebar about 1150mm long welded across the tops of the angle, or even drilling holes to pass the rods through the angle pieces and welded to suit the spacing of the stringers.
I am a bit worried if I have allowed enough reinforcing, I can't find any help through google ( maybe I am using the wrong terminology for the search ), maybe someday there will be 2 big fellas carrying a full esky up the stairs......
Am I asking for trouble here, should I just forget it and go back to the timber treads ?
