Galvanized coils are rolled galvanized steel plates, usually by immersing the steel coils in molten zinc, or using other galvanized processes to cover a layer of zinc on the surface of the steel plate.This material is very common in various industrial and construction applications and has a variety of advantages, as shown below：
1.Corrosion resistance: One of the biggest advantages of galvanized coils is their excellent corrosion resistance.The zinc layer forms a protective layer on the surface of the steel plate, which can effectively resist corrosion in most environments, especially humid and highly corrosive environments.This makes galvanized coils very suitable for outdoor and humid applications, and can extend the service life of the material.
2.Low maintenance cost: Due to its corrosion resistance, the maintenance cost of galvanized coils is relatively low.They are not easy to rust, so they do not require frequent repairs and maintenance, which helps reduce overall operating costs.
3. Strength and stiffness: The galvanized coil retains the strength and stiffness of the original steel plate.This makes them very useful in applications that need to withstand heavy loads or have structural requirements.
4. Good appearance: Galvanized coils usually have a bright silver-white appearance, which makes them very popular in the fields of construction, decoration and manufacturing.Their appearance attractiveness can enhance the overall beauty of the product or structure.
1.Hot-dip galvanized color coated steel sheet(prepainted galvanized steel sheet)The product obtained by coating an organic coating on a hot-dip galvanized steel sheet is a hot-dip galvanized color-coated plate. In addition to the protective effect of zinc, the hot-dip galvanized color-coated sheet also protects against rust and has a longer service life than hot-dip galvanized sheet;
2.Hot-dip aluminum-zinc color coated sheet(prepainted galvalume steel sheet)Hot-dip aluminum-zinc steel sheets can also be used as color-coated substrates (55% AI-Zn and 5% AI-Zn);
3.Electroplated zinc color coated sheet The electro-galvanized sheet is used as the substrate, and the product obtained by baking with the organic coating is an electrogalvanized color-coated plate. It has a beautiful appearance and excellent processing properties, and therefore can be mainly used for home appliances, audio, steel furniture, interior decoration, and the like.
Polyester (PE): Good adhesion, rich colors, wide range in formability and outdoor durability, medium chemical resistance, and low cost.
Silicon modified polyester(SMP): Good abrasion resistance and heat resistance, as well as good external durability andchalking resistance, gloss retention, general flexibility, and medium cost.
High Durability Polyester(HDP): Excellent color retention and anti-ultraviolet performance, excellent outdoor durability and anti-pulverization, good paint film adhesion, rich color, excellent cost performance.
Polyvinylidene Fluoride(PVDF): Excellent color retention and UV resistance, excellent outdoor durability and chalking resistance, excellent solvent resistance, good moldability, stain resistance, limited color, and highcost.
Spangle is formed during the hot-dip galvanizing process. The size, brightness, and surface of spangles mainly depend on the composition of zinc layer and the cooling method. According to the size, it includes small spangles, regular spangles, big spangles, and free spangles. They look different, but the spangles almost will not influence the quality of galvanized steel. You can choose according to your preference and purpose.
