Galvanized Steel I-Beam
Galvanized Steel I-Beam
Galvanized I-beams (also known as galvanized H-beams) are carbon structural steel sections (such as Q235B) with an "I"-shaped cross-section. They undergo a hot-dip galvanizing process to form a zinc alloy coating on the surface, making them a load-bearing structural material used to enhance corrosion resistance.
