An H-Beams is a structural steel section with an H-shaped cross-section. It is a type of structural steel with high load-bearing capacity, making it particularly well-suited for projects that must support heavy loads.
Identifying characteristics
When viewed in cross-section:
– It features two horizontal flanges.
– It has a vertical central section known as the web.
– The width of the flanges is typically quite large relative to the height of the web.
– It can be manufactured through hot-rolling or by welding individual components together (built-up section).

Technical Specifications
– H: Section height
– B: Flange width
– tw: Web thickness
– tf: Flange thickness
