Hot-dip galvanized steel strip galvanizing method

Cold-formed thin-walled section steel is commonly used black material, cold-formed after a simple descaling and painting treatment is put into use, its service life is subject to certain limitations (generally in about 5 years that will appear large areas of rust).

The production process and advantageous characteristics of pickling plate

Pickled plate is a kind of steel plate treated with acid washing, which is mainly used in the manufacture of high-grade kitchenware, construction materials, auto parts and other fields. The production process of pickled plate needs to be processed by pickling equipment and pickling solution to remove surface oxidized skin

Characteristics of several different hot-dip galvanized and zinc alloy coatings

Hot-dip galvanizing is a metallurgical reaction process. From a microscopic point of view, the hot dip galvanizing process is a dynamic equilibrium of two kinds: thermal equilibrium and zinc-iron exchange equilibrium.

Hot dip galvanized steel sheet fire rating analysis

Hot-dip galvanized steel sheet is made by washing, pickling and galvanizing steel sheet, which has good corrosion resistance and decorative properties. Meanwhile, in the field of construction, hot-dip galvanized steel sheet is also widely used in the production of fireproofing materials and processing of building materials.
