Galvanized steel H-beam is divided into galvanized steel H-beam and hot-dip galvanized steel H-beam. During the manufacturing process, galvanized steel H-beam is formed by crimping and welding galvanized steel strips. After trimming and polishing, it is ready for sale. The appearance of the zinc layer of galvanized H-shaped steel is very smooth, dense, and evenly arranged; it has excellent mechanical properties and corrosion resistance; its zinc consumption is 60% to 75% lower than that of hot-dip galvanizing. It is also known as cold-dip galvanized H-beam. Hot-dip galvanized steel H-beam is expensive because of the complicated construction process. It has the characteristics of high strength, good toughness, good formability and excellent welding performance.
