How long do steel beams last?
between 100 and 150 years
A steel beam should last between 100 and 150 years. Changes in technology are expected to increase the life span of steel beams.
What causes steel beams to rust?

Why are steel beams red?
The red that you see when you erect your I-beam steel building is the red-oxide primer applied to the steel. This is basically a short-term finish that protects the steel from moisture. As long as you don’t scrape it off, it will serve its purpose of creating a rust-resistant finish, at least for the short term.
How do you stop steel from rusting in construction?
Applying a coat of zinc to steel protects rusting. The process of coating steel with a layer of zinc is known as galvanization. The process uses hot-dip galvanizing or electroplating technology. The rust created on the steel parts is transferred on the zinc layer and hence, protecting the steel from damage.
