Prepainted steel coil is based on galvanized steel coil or galvalume steel coil as substrate, that has had paint applied to both sides through a continuous coil coating process, which produces a uniform paint finish. The metal is unwound, cleaned and chemically treated during the process. Depending on product specifications, one or both sides may then be primed and coated, oven cured and rewound. Usually the paint is used with polyester paint, silicone modified polyester, high-durable paint, pvdf paint or other specified paint. A polymer coating is available in various colours as well as a matte, lustre or decorative natural finish (granite, wood, etc). Organic coated galvanised steel is corrosion-resistant, has excellent mechanical properties and can be formed, profiled or stamped. Advantages of JINBOWANTONG prepainted steel coil Corrosion resistance / Resistance ultraviolet rays / Resistance to humid heat / Resistance to low temperature Classification and properties of Prepainted steel Base materials   Prepainted steel coil is based on galvanized / galvalume steel coil as substrate, The greater the thickness of the zinc / al-zinc coating, the better the corrosion resistance. The thickness of the zinc / al-zinc coating mainly affects the cut corrosion performance of the pre-painted galvanized steel coils, and the influencing factors include the finish coating, primer, substrate thickness, and metal coating thickness. We produce pre-painted steel coils for galvanized / galvalume steel substrates with metallic coating of G40, G60, and G90. Please select the appropriate one according to the use environment.

Galvalume steel coil is based on cold-rolled steel strip as substrate, it is solidified of 55% aluminum, 43.4 zinc and 1.6% silicon solidi-filed at 600℃ high temperature and composition. Prepainted galvalume steel coil combines durability, excellent heat resistance, and formability of aluminum, and those of zinc that offer high heat resistance and excellent corrosion protection, to form into this kind of dense crystalline quaternary alloy coated steel.The surface of the galvalume steel sheet is characterized by smooth, flat and gorgeous stars, and its base color is silver white. Galvalume(Aluzinc) Steel Coil Process The common manufacturing process is known as the hot-dipping process. Let's review step by step. 1. Pre-treatment: Through the pre-treatment system, the contaminants on the surface of the base metal will be removed. It often includes degreasing, rinsing, pickling, etc. 2. Hot-dip Galvalume Process: After going through the annealing furnace, steel sheets are dipped into the Al-Zn pool. Then there is an air knife to remove the extra coating to keep the thickness of the coating. 3. Inspection & Coiling The coated steel sheet will go through the quality control system and then be rolled up for sale. So the structure of Galvalume steel includes: Base metal (cold-rolled steel sheets) The al-Zn coating layer (top and back sides)

Galvanized steel coil is based on cold-rolled steel strip as substrate, after continuous hot-dip galvanizing process and produced products. This method tightly adheres the coating to the steel with an iron-zinc alloy bonding layer formed by a diffusion process while the heated steel strip is in contact with the molten zinc. It is an excellent resistance to atmospheric corrosion of coated steel. cold-rolled sheet after the zinc can extend the service life for 15-20 years. Galvanised steel coils are successfully used in industries with stringent requirements for corrosion resistance, durability, strength and appearance, and can be formed or have various coatings applied. The key standards to be followed for the production of galvanised coils include EN 10346 (Europe), ASTM A653 / A653M (US). Manufacturers also have their own original standards. Hdg coil classification, product range and properties Standards applied in different countries to set the requirements for hot dipped galvanized steel coils specify steel grade and size ranges for these products. Hot dipped galvanised coils are classified based on the following features: Application of coated steel (profiling, cold forming, manufacture of steel structures) Chemical composition of coating material (pure zinc, zinc-iron/zinc- aluminium/aluminium-zinc/zinc-m , agnesium alloys, etc) Thickness/weight of protective coating ►HDG coils according to European standards Galvanised steel coils as per the European EN 10346, can be coated with zinc, zinc-iron alloy, zinc-aluminium alloy, aluminium-zinc alloy or aluminium- silicon alloy: Zinc coating (Z) is achieved by dipping the prepared strip into a bath with molten alloy, containing at least 99% zinc. This is the most common and traditional way of protecting rolled steel from corrosion. Zinc-iron coating (ZF) is formed by dipping a strip into a bath of molten zinc (at least 99% zinc) with further annealing to form a zinc-iron coating with an Fe content of 8-12%. Such coating is stronger than the traditional zinc coating and has better adhesion with substrate steel due to mutual diffusion between the iron and zinc in the surface layers. That is why this coating is less exposed to lamination or pitting under impact, mechanical stresses or deformation of treated products. Zinc-aluminium coating (ZA) is applied to rolled steel by dipping it into a bath of zinc and about 5% aluminium with a minor content of mishmetal (mix of metals). Rolled steel with such coating has better formability and corrosion protection properties compared with zinc-coated steel. Aluminium-zinc coating (AZ) is applied by dipping steel into a bath of molten metal consisting of 55% aluminium and 1. 6% silicon (with the remaining being taken up by zinc). The combined action of these metals ensures the best corrosion protection compared with other coatings. Aluminium-silicon coating (AS) is created by dipping steel into a bath of molten metal containing aluminium and 8-11% silicon. Galvanized steel coil with such coating is highly resistant to oxidation at high temperature (up to 650°C) and highly resistant to chemical corrosion. Galvanised steel coils manufactured according to the EN 10346 can be made from the following steels: Low-carbon steel for cold forming (DX51D – DX57D). These products are classified based on suitability for cold forming: DX51D – bending and profiling quality; DX52D – drawing quality; DX53D – deep-drawing quality; DX54D – special deep-drawing quality; DX55D – special deep-drawing quality (only +AS); DX56D – extra deep drawing quality; DX57D – super deep drawing quality. Steel for construction and framing (S220GD – S550GD). Rolled products are arranged in increasing yield stress (Rp0. 2), which is indicated in the marking. Rolled products of S220GD – S550GD steel are mainly used in the manufacture of formed sections (Z-, C-, sigma-, U-shaped profiles, etc) for light-gauge steel structures. Steel with high yield strength for cold forming (HX160YD, HX180YD, HX180BD, HX220YD, HX300LAD, etc). Such rolled products are arranged in increasing yield stress (Rp0. 2), which is indicated in the marking. The marking also contains the following information: H – high-strength flat rolled products for cold forming; Х – as-rolled condition (hot-rolled or cold-rolled) is not defined; D – designed for hot-dip coating; B – heat-treated steel; Y – steel with higher formability; LA – low-alloy / micro-alloy steel. Cold-formable multi-phase steel (HDT450F, HCT490X, HDT590X, HCT780X, HCT980X, HCT780T, HDT580X, etc). Rolled products are arranged in increasing minimum tensile strength (Rm0. 2), which is indicated in the marking. The marking also contains the following information: H – high-strength flat-rolled products for cold forming; С – cold-rolled products; D – hot-rolled products; Т (nnn) – the minimum tensile strength in MPa. The last symbol: F – ferrite-bainite, Х – dual-phase; Т – TRIP, С – complex-phase; М – martensite. Galvanised coils as per the EN 10346 standard can be coated with zinc, zinc- iron alloy, zinc-aluminium alloy, aluminium-zinc alloy or aluminium-silicon alloy. The coating weight is expressed as grams per square metre and characterises the weight of the coating deposited on the both strip surfaces. The coating type (Z, ZF, ZA, AZ, AS) and nominal weight are indicated in the coating designation. Depending on the type of protective layer, the minimum weight of coating on both surfaces of a galvanized product can be 100-600 g/m2 (average value for three spots). https://www.jinbosteel.com/
