Hot dip galvanizing is also called hot dip galvanizing and hot dip galvanizing. It is an effective metal anticorrosion method.
Hot-dip galvanizing is also called hot dip galvanizing and hot dip galvanizing. It is an effective metal anticorrosion method.
Hot-dip galvanized steels include hot-dip galvanized steel pipes, hot-dip galvanized steel sheets, hot-dip galvanized steel strips, hot-dip galvanized angle steels, hot-dip galvanized flat steels, etc. These are hot-dip galvanized steel products, which are hot-plated for these products. Zinc is used for anti-corrosion purposes.
Steel: A material of various shapes, sizes, and properties required for press forming of steel ingots, billets, or steel. Steel is an indispensable material for the construction and realization of the country. It is widely used and has many varieties. According to the shape of the section, steel is generally divided into four categories: profiles, plates, pipes and metal products. In order to facilitate the production of steel, Order supply and good management, and is divided into heavy rail, light rail, large section steel, medium-sized steel, small section steel, steel cold-formed steel, high-quality steel, wire, medium-thick steel, thin steel, electrical silicon steel sheet, strip steel , seamless steel pipe steel, welded steel pipe, metal products and other varieties. Steel is an iron-carbon alloy containing between 0.04% and 2.3% carbon. In order to ensure its toughness and plasticity, the carbon content generally does not exceed 1.7%. In addition to iron and carbon, the main elements of steel include silicon, manganese, sulfur, and phosphorus.
Hot-dip galvanizing, also known as hot-dip galvanizing and hot dip galvanizing, is an effective metal anti-corrosion method and is mainly used in metal structures in various industries. The rust-removed steel is immersed in a zinc solution melted at about 500 ° C to adhere the zinc layer to the surface of the steel member, thereby preventing corrosion. The hot-dip galvanizing production process mainly includes: original plate preparation → pre-plating treatment → hot dip plating → post-plating treatment → finished product inspection.
The main method used for galvanizing steel surfaces today is hot-dip galvanizing. Hot-dip galvanizing has evolved from older hot-dip methods, and since France applied hot-dip galvanizing to industry in 1836, it has been 170 years old. However, in the past 30 years, with the rapid development of cold rolled strip, the hot dip galvanizing industry has developed on a large scale. Hot-dip galvanized steel is in high demand in the galvanized steel market. On the contrary, electro-galvanized steel is used less. Only some small enterprises are still manufacturing electro-galvanized products, and electro-galvanizing has been banned.
