Description of Prepainted Galvalume Rolled Coil
Aluminum zinc coils is a kind of coated steel coil/sheet. With the cold rolled steel of different strength and thickness as substrate, it is produced through applying Al-Zn coat on both faces by hot dip process. In its coating, Al accounts for about 55%, Si 1.6%, while the remaining is Zn. Aluminum zinc coils enjoys both the physical protective feature and durability of Al and the electrochemical protective property of Zn. And its surface has bright silver color and regular embossed-like figure, which are highly decorative.
Main Feature of Prepainted Galvalume Rolled Coil
1.Corrosion resistance: It mainly depends on the aluminum protection. When the zinc being worn, the aluminum will form a dense layer of aluminum oxide, resist corrosion material to prevent further corrosion inside.
2. Heat resistance: Aluminum zinc alloy steel sheet has excellent heat resistance, can withstand high temperatures over 300 centigrade, and is similar with aluminized steel high temperature oxidation resistance. It often used in chimney pipes, ovens, fluorescent lighting device and the device cover.
3. Heat reflective: Galvanized steel plate heat-reflective high rate is twice as galvanized steel, often used to make insulation materials.
4. Economy: Because density of 55% AL-Zn is smaller than the density of Zn, so in the same weight and thickness of Galvanized zinc layer, aluminum-zinc steel plate is larger area more than 3% of galvanized steel sheet.
Applications of Prepainted Galvalume Rolled Coil
1. Construction and building: roofing; ventilating duct; handrail; partition panel;etc.
2. Electric appliance: refrigerator; washing machine; refrigerator; DVD;etc.
3.Transportation: oil tank; road sign; etc.
4.Agriculture:barn; etc.
5.Others:vending machine; game machine; etc.

- Q: How are steel coils used in the production of packaging machinery?
- Steel coils are used in the production of packaging machinery primarily for the construction of structural components such as frames, supports, and rollers. The high tensile strength and durability of steel coils make them ideal for handling heavy loads and ensuring the stability and longevity of packaging machinery during operation.
- Q: How are steel coils uncoiled?
- Steel coils are uncoiled using a mechanical process called decoiling, where the coil is placed on a mandrel and then unwound using a motor-driven system. The coil is pulled through a set of straightening rolls to ensure it is properly aligned and then fed into the production line for further processing or fabrication.
- Q: How are steel coils processed and treated?
- Steel coils are processed and treated through a series of steps. Initially, the steel is cleaned and pickled to remove any impurities. It is then passed through a series of rolling mills to reduce its thickness and increase its length. The coils are then annealed to improve their strength and ductility. Further treatments such as galvanizing or coating can be applied to enhance corrosion resistance or improve aesthetic appeal. Finally, the coils are cut and packaged according to customer specifications before being shipped for various applications in industries such as construction, automotive, and manufacturing.
- Q: At what temperature does steel start to warp or soften.
- Just okorder
- Q: Can steel coils be reused?
- Yes, steel coils can be reused. Steel is a highly recyclable material, and steel coils can be melted down and used to produce new steel products. Recycling steel coils not only helps to conserve resources and reduce waste but also contributes to a more sustainable and environmentally-friendly manufacturing process.
- Q: What are the dimensions of steel coils used in the household appliance industry?
- The dimensions of steel coils used in the household appliance industry can vary depending on the specific application and requirements. However, standard dimensions for steel coils commonly used in this industry range from 0.4mm to 3mm in thickness and 600mm to 1500mm in width. The length of the coils can also vary, typically ranging from a few hundred meters to several kilometers. These dimensions ensure that the steel coils are suitable for various household appliance manufacturing processes, such as forming, stamping, and welding. It is important to note that these dimensions are not fixed and can be customized based on the specific needs of the appliance manufacturer.
- Q: What are the common coil handling equipment used in the industry?
- Some common coil handling equipment used in the industry include coil cradles, coil cars, coil reels, coil straighteners, coil feeders, and coil tippers. These equipment are used to efficiently and safely handle coils of various sizes and weights during manufacturing processes.
- Q: I have a set of steel pans with copper bottoms. When I cook with oil it always burns the oil to the pan and takes days to clean. I don't think I should use steel wool, since it might scratch the surface. Does anyone know a faster way to clean scorched oil off a steel pan?
- Get a can of Barkeeper's Friend. It's a powdered cleanser. It's gentle enough to be used on a ceramic cook top but still strong enough to get metal clean. Cheap and made from rhubarb leaves! Dampen the pan with water, sprinkle generously and smear around with a sponge with one of those non-stick safe nylon scrub pads. Wait about 10-15 minutes to let the product do some of the work for you. Come back and give it a good scrub. Reapply if necessary. I have all stainless steel cookware and use the Barkeeper's to keep them looking nice; especially since they are on display with my pot rack. I also have some copper pieces used for decoration and I use the Barkeeper's to keep them looking nice. It cleans them up faster and better than any of the homemade concoctions or metal cleaners without the residue. And I do use it on my ceramic cook top too! Be sure to wash and rinse the pan after you get it clean; it does leave a haze if you don't.
- Q: I wanted to know what is steel fabricating?
- Steel Fabricating/or Steel Fabricators is just a fancy way of saying that they sell steel products and a variety of related services. Thomas steel products has a wide range of steel products and services, from Windsor Republic Door Dist, Tie Wire, Steel Doors Frames, Snap Ties, S Parker Hardware Distributor, Reinforcing Steel Detail Drawings Avail, Rebar Fabrication, o_O.
- Q: So...I'm learning about how steel is made and I'm wondering if there is a more environmentally friendy method. I view it as unfriendly b/c of the oxygen that is injected when the steel is in the blast furnace or electric arc furnace. This oxygen bonds w/ the carbon to produce CO and CO2. THis is necessary to reduce the amount of carbon content to produce harder steels. So what other methods are there that can be used w/o having to end up w/ co and co2? thanks
- From what I understand of it, US steel is better as the steel is more recycled than Canadian, so a lot of that oxygen / CO2 has already taken place compared to working from ore. The second reason US steel is environmentally ahead of Canadian is that US tends to use Electric Arc, while Canadian uses Basic Oxygen, Basic Oxygen uses more energy than electric arc, and I think it also uses more oxygen, but I would suspect that oxygen that it uses is 'waste oxygen' and not converted into Co2 because the Co2 process is limited by the carbon, and steel only has so much carbon.
