That is a good point. Most of the ones I see around her are, but that does not mean those are. They are usually aluminum to prevent rusting for a life of being outdoors. Like most highway signs and other objects like street lights. Those are likely 20 years old like the rest of the track, but it is a dessert.
I am just guessing it is aluminum and the expect it to deform and bend under a normal impact. Steel would be too strong.
