What are the surface treatment methods of Expanded Metal Mesh?
There are many types of Expanded Metal Mesh. According to the material classification, there are various plates such as aluminum plate, low carbon steel plate, stainless steel plate, steel plate, and aluminum-magnesium alloy plate. Classification of Expanded Metal Mesh according to its use can be widely used in highways, railways, water conservancy, construction, etc. It is also a common item in electrical, window, machinery and other protections. Aquaculture and Expanded Metal Mesh also have important applications. In addition, products with special specifications can be specially formulated according to customer requirements.
Expanded Metal Mesh has many hole types. According to the hole type, it is divided into: hexagonal hole steel aluminum metal mesh, fish scale steel aluminum metal mesh, fancy steel aluminum metal mesh, and tortoise metal mesh.
The galvanized sheet mesh is treated by surface galvanizing technology and can be divided into hot-dip galvanizing and cold-galvanizing. Now cold-galvanizing has been eliminated. Currently, the most commonly used is hot-dip galvanizing technology. For 30 years, with cold-rolled strip technology The rapid development. The hot dip galvanizing technology industry has been greatly improved and is widely used in the surface treatment of metal products.
The production process of hot-dip galvanized steel mainly includes original plate preparation, pre-galvanizing treatment, post-plating treatment, quick-sold products, inspection, etc. The hot-dip galvanizing process can be divided into indoor annealing and wire annealing according to different processing methods. Big class.
Expanded Metal Mesh's surface treatment method is wired external annealing (single sheet hot-dip galvanizing method), wet hair (single sheet hot-dip galvanizing method), in-line annealing Sendzimir method (protective gas method), ie hot-dip galvanizing Huilin The method (continuous hot-dip galvanizing method for strip steel), modified Sendzimir method, Silas method and Sharon method, and US joint method (with Kawasaki method in Japan) are widely used in the surface treatment of Expanded Metal Mesh.
