Steel is a metal alloy composed of iron and carbon. These are two basic ingredients, but many other elements are often added to further increase strength, durability, and longevity.
1. Different materials
Galvanized iron usually refers to galvanized hot-rolled coils. It is coated with a layer of zinc on the surface after pickling, cleaning, baking and other processes during the hot rolling process. Galvanized steel usually refers to galvanized cold-rolled sheets, which are coated with a layer of zinc on the surface after rust removal, pickling, electroplating and other processes during the cold rolling process. The materials of the two are different, so each has different characteristics and application scope.
2. Different performance
Galvanized iron has low surface hardness and poor corrosion resistance, but it has good processability, plasticity and weldability, and is suitable for some products that do not require high corrosion resistance. Galvanized steel has higher surface hardness, better corrosion resistance, and better corrosion resistance to oxidizing gases and water vapor. It is suitable for various products that require higher corrosion resistance.
3. Different uses
Galvanized iron is widely used in automobiles, home appliances, construction, railways and other fields, such as automobile casings, kitchen appliances, furniture, pipes and other products. Galvanized steel is more commonly used in specific fields such as chemical industry, electric power, and ocean, such as offshore platforms, chemical containers, oil and gas pipelines, etc.
