It will be an exterior stair connecting to a steel frame. So only exposed to the outdoor elements but NOT near the coast.

Is the structural steel hot dip galvanised or otherwise coated?

Kingnero:
The structural steel is painted. Not galv.

RE: Bolting Structural steel to aluminum

Do you have any more information that might be of interest to us? Like the clips are anodised perhaps?

RE: Bolting Structural steel to aluminum

(OP)
The aluminum is mill finished and not anodised. I'm not sure of the aluminum make up, but the structural steel is A992 Gr. 50ksi and I believe the steel is painted.
