- Galvanized channel steel is a kind of steel products with zinc coating on the surface of ordinary channel steel, which has the basic characteristics of channel steel, and also has good corrosion resistance and aesthetic properties.
- Steel composition: the basic composition of galvanized channel steel is the same as ordinary channel steel, the main component is carbon steel, while containing a small amount of silicon, manganese, phosphorus and other elements. Different galvanized channel steel in the thickness of the zinc layer and the composition of steel and other aspects of the differences to adapt to different occasions.
- Production process: galvanized channel steel production process is relatively complex, mainly including steel pretreatment, galvanizing treatment and post-treatment and other links.
– Steel pretreatment: first of all, the steel surface pretreatment, including pickling, dissolving, cleaning, etc., in order to facilitate the subsequent coating treatment.
– Galvanizing treatment: the pre-treated channel steel immersed in molten zinc liquid, so that its surface to form a layer of zinc, the formation of galvanized channel steel, specifically including hot-dip galvanizing and electro-galvanizing two methods.
– Post-treatment: Post-treatment of galvanized channel steel, such as cooling, coating, cutting and so on, in order to facilitate transportation, storage and use. - Characteristics: Galvanized channel steel has the following characteristics:
– Good corrosion resistance: Due to the zinc coating on the surface, galvanized steel channel has good corrosion resistance, which can effectively prolong the service life and is suitable for use in various harsh environments, such as marine, chemical and other fields.
– Good aesthetics: galvanized channel steel surface shows silver-white, beautiful appearance, can be used in some of the appearance requirements of the occasion, such as construction, decoration and other fields.
– Strong impact performance: the zinc layer of galvanized channel steel has good impact performance, which can effectively resist the impact and extrusion of external forces, and is suitable for some demanding industrial applications.
– Good stability: galvanized channel steel cross-section shape is stable, not easy to deform, with good seismic performance and stability, suitable for some of the higher requirements for structural stability of engineering projects.
– Good fire resistance: galvanized steel channel has fire resistance to a certain extent, can effectively reduce the occurrence and spread of fire, suitable for some of the higher requirements for fire prevention occasions. - Application fields: galvanized channel steel is widely used in construction, manufacturing and other industries. Specific applications are as follows:
– Construction field: Galvanized channel steel is used for supporting, framing and wall components in building structures, such as roof frames, beams and columns, door and window frames of buildings. Due to its good corrosion resistance and beautiful appearance, it is often used for exterior wall decoration.
– Manufacturing: Galvanized channel steel is used to manufacture various mechanical equipment parts, such as light machine tools, electrical equipment, automobiles and so on. Due to its strong impact performance and good stability, it is suitable for some demanding industrial applications.
– Mining equipment: galvanized channel steel is used for mine supports, mine pillars, mine roads and so on. Due to its good corrosion resistance, it can adapt to the harsh mining environment.
– Rail transportation: galvanized channel steel is used in rail transportation industry for steel rails, light rail, subway station platforms and so on. Due to its good fire performance and good corrosion resistance, it can effectively extend the service life and is suitable for use in various harsh environments.
– Shipbuilding: Galvanized channel steel is used for keel, deck beams, bulkheads and other structural components in shipbuilding. Due to its good corrosion resistance and stability, it can be adapted to the use in the marine environment.
– Bridge construction: galvanized channel steel is used in bridge construction for girders, arch ribs, bridge deck plates and so on. Due to its good corrosion resistance and good stability, it can be adapted to various harsh environments .
– Petrochemical industry: galvanized channel steel is used in petrochemical engineering reactor, tower equipment, heat exchangers and so on. Because of its good corrosion resistance, it can be adapted to the use of various corrosive media.
– Steel Structure Building: Galvanized channel steel is used for roof frames, beams, trusses, etc. in steel structure building. Due to its beautiful appearance and good corrosion resistance, it is suitable for all kinds of building decoration and structural support. - Galvanized channel steel is a steel product with good corrosion resistance and aesthetic appearance, which has the advantage of being able to adapt to more usage occasions than ordinary channel steel. As it is widely used in construction, manufacturing and other industries, it is a very important steel product.
