Steel does not have to melt to fail in a fire. Ask any structural engineer why steel beams have to be fireproofed and wood beams do not.

At about 950Deg F, a steel beam will fail under it's own weight. A wood beam will hold until it burns through.

I am not an engineer, but I spent much of my life working with them. If I have questions about structural strength, I will ask one of them, Not some Hollywood b*^ch.

I had a carpentry book which had an after fire picture of a failed steel beam wrapped around a wood beam.
