WebAnother result of extreme temperatures is that material will expand or contract in proportion to the temperature, due to physics. So when the temperature rises in a steel structure the atoms start to vibrate more and more. This thermal agitation, in turn, leads to an increase in interatomic distances and thus causes an expansion in the material.
