what are the men who work building the skyscrapers called?

The men who work building skyscrapers are generally called ironworkers or steelworkers. They often perform highly skilled and dangerous tasks involving the steel skeleton of skyscrapers. They have also been historically nicknamed "sky boys" or "air-treaders" due to their work balancing on narrow steel beams at great heights. Another term used for these construction workers is "roughnecks," denoting their tough nature and the hazardous conditions they work under. Additionally, Native American Mohawk ironworkers have been notably recognized for their significant contributions in skyscraper construction, sometimes called "Mohawk skywalkers" because of their fearlessness at heights and skilled work on steel frameworks.
