About the long horizontal steel girder beam with bolt holes
A girder is a strong beam that forms the main horizontal support in a building or bridge. Smaller beams rest on top of it, so the girder carries a great deal of weight. Many are shaped like the letter I when you look at the end, which makes them both strong and light. Add it to a how-things-are-built lesson, tracing the path along the long steel beam.
- A girder is a main beam that holds up smaller beams above it.
