Which norms are staircase stepping angle using steel bars to do corners of the practice
I have not heard of this specification, only seen with copper bars do staircase corner.
Because the steel exposed to the air is easy to rust, the volume becomes larger, will open the cement mortar, causing the paint layer cracking off.
So in principle, should be used copper or stainless steel as well
This is not standardized provisions need to do reinforcement angle
