I've never heard of steel-framed windowwall before. The closest you'll get is maybe steel reinforcement plates tucked inside the aluminium mullions, but even that's only on high-end curtainwall, high-end blast resistant curtainwall at that.
It's safe to say the only steel in that tower will be in the rebar and in the handrails running up the stairwell.
