I-BEAM 4X4

I-beam is a structural beam characterized by its "I" or "H"-shaped cross-section, consisting of two horizontal "flanges" connected by a single vertical "web". This design provides a high strength-to-weight ratio, making it highly effective at withstanding bending forces in the flanges and shear forces in the web, which is why it's widely used in construction for buildings and bridges to support heavy loads and create structural frameworks.
