I went down memory lane. In 2020, I dropped out of Dartmouth, flew back to Nepal on the second flight after borders reopened, and spent a year doing things I never expected.
One of them: building one of the first three-story I-beam steel structures in Far West Nepal. No local expertise. No supply chain. A crew that had never done it before. We figured it out anyway.
What is the useful life of something like this compared to an RCC structure? Do you have to keep painting them to protect it from rust?
You do see steel used in mobile towers etc because you may not be able to place an RCC structure of that height on top of a building not designed for those loads. And in single story workshops/sheds.
