This photo should be a small staircase with a hole in the floor. There is something wrong with the steel bar itself: after the steel bar at the plate is cut off against the wall, it should be similar to that after the upper and lower steel bars are bent, the anchorage should be strengthened by lap welding or welding with horizontal steel bars to ensure the anchorage of the steel bar at the back plate of the wall.

The decoration of steel beams should be combined with fire inspection and acceptance. It's best to avoid it, otherwise it's very troublesome. If you can't avoid it, you have to paint it with fire retardant.

There are too many final decoration methods. You can use wood, paint and aluminum.
