Expansion of Steel in the Sun
Expansion of Steel in the Sun
(OP)
If a steel beam is setting in the sun when the ambient temperature may be 90 deg. F, could the steel have an actual internal temperature that is a much higher temperature, say 120 deg.?
I believe I read this somewhere but for the life a me I can't remember where.

For the bridges I work on (usually painted a light color and over large bodies of water), the steel temperature usually lags behind ambient temperature by several hours -- this often means that the steel never gets as warm as the peak ambient temperature, since by then the air has cooled back down.
I'd imagine that unpainted steel or steel not over bodies of water would be less forgiving.

anecdotal: I was told by contractors that in Palm Springs CA desert in the Summer, steel was too hot to handle past midmorning.... suggesting a significantly higher than ambient temperature

As I recall, on one 105°F day, the steel temperature in the Sun at about 3 p.m. was around 180°F. On the north side of the tank, the shaded steel was around 100°F.
