Main Feature of Al-Zinc coated steel 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 Al-Zinc coated steel coil
1. Construction and building: roofing; ventilating duct; handrail; partition panel;etc.

- Q: What are the different coil packaging methods used for steel coils?
- Steel coils can be packaged using various methods to guarantee their protection and secure transportation. These methods also help optimize storage space. Some of the commonly used packaging methods for steel coils are as follows: 1. Strapping: Metal or plastic straps are used to secure the steel coils. This ensures stability and prevents unrolling or shifting during transportation. Strapping is suitable for smaller coils or when other packaging methods are also utilized. 2. Stretch wrapping: Steel coils are tightly wrapped using a stretch film. This technique provides excellent protection against dust, moisture, and other contaminants. It also keeps the coils tightly bound and prevents movement during handling and transportation. 3. Steel banding: Steel bands or straps are employed to secure the coils. This packaging method offers superior strength and durability. It is ideal for larger and heavier steel coils that require additional reinforcement. 4. Wooden crating: Particularly large or heavy steel coils are packaged in wooden crates. These crates provide enhanced protection against impacts, moisture, and other external factors. Wooden crating is commonly used for long-distance transportation or when coils need to be stored for extended periods. 5. Coil saddles: Specialized devices called coil saddles are used to package large coils securely. These devices prevent rolling or movement. Coil saddles are preferred when strapping or wrapping is not feasible. 6. Paper interleaving: Sheets of paper are placed between each layer of steel coils to prevent damage caused by friction. This method is commonly used for coils with a high surface finish or those susceptible to scratching. Each of these packaging methods offers distinct advantages and is chosen based on factors such as coil size, weight, transportation requirements, and desired level of protection. By employing these methods, steel coil manufacturers and distributors can ensure the safe arrival of their products in optimal condition.
- Q: Can steel coils be coated with self-cleaning materials?
- Yes, steel coils can be coated with self-cleaning materials. These materials, typically hydrophobic or photocatalytic coatings, can help prevent the accumulation of dirt, grime, and other contaminants on the surface of the steel coils. This not only maintains the aesthetic appeal of the coils but also reduces the need for frequent cleaning and maintenance.
- Q: Me and my cousin have been arguing about this. I said that superman is made out of steel, but he says that people just call him the man of steel because he's hard like steel. Does he have steel in his body?
- Superman has no steel in his body. When Superman was called The Man of Tomorrow, which was many years ago, he wasn't made of tomorrow.
- Q: I want to anodize steel using heat. some steel turns gray instead of coloring when I heat it up using a torch.
- Steel doesn't anodize in the sense that aluminum and some other metals do. However, it can be heat-colored. The trick is to clean the surface first (it must be oxide free), then heat gently until the colors appear. These are called temper colors in steel. They are due to a thin adherent layer of oxide that forms and thickens as temperature is increased. They are quite temperature dependent. As the steel is heated, the first color to appear is pale yellow. This will progress through darker yellows, browns, purples, and blues as the temperature rises. Above blue, the oxide becomes the gray/black color you are apparently getting - this is the result of heating too fast and too hot. See the chart at the site below for colors in plain carbon steel. Note that the temperatures are pretty low - It all starts around 400 F and if you go above 600 F the show's all over.
- Q: Iron melts faster when there will be low carbon in Iron.During steel making the molten Iron gets purified and alloying being done through the process. How the carbon is being controlled at Iron melting stage and what it is called?
- Steel is usually made in a two-step process. As you may know, carbon, in the form of coke, is added to the iron ore during the initial smelting process. This is the first step. The conversion of iron ore into raw iron is accomplished with a blast furnace. Carbon dissolves with the iron during the smelting process. The amount of carbon in the iron is generally not controlled at this point as this would be too difficult, the excess carbon is removed in the next step. The result is pig iron which is crude iron that has a very high carbon content, and a large amount of impurities. Pig iron is almost as brittle as glass, and it is useless in this form. In most modern steelmaking operations, molten pig iron is tapped from the blast furnace three or four times per day- it is not allowed to cool. The liquid pig iron is carried in ladles directly to a Basic Oxygen Furnace which converts the pig iron into steel. The basic oxygen converter uses a stream of pure oxygen to burn off the excess carbon. Impurities are also burned off, particularly phosphorus, silicon, and sulfur (which damage the steel's properties.) These elements all have a much higher affinity for oxygen than iron does, so the iron itself remains unchanged. Once the carbon content and the impurities are reduced to the desired level. The oxygen is shut off, and the iron has now become steel. At this point other alloying elements may be added, such as chromium, manganese, or molybdenum. These elements improve the steel's properties, but also add to it's price. If necessary, more carbon can be added as well if the carbon content has accidentally dropped too low. Finally, molten steel from the basic oxygen furnace is poured off. It can be cast into ingots, billets, or thin slabs.
- Q: How are steel coils processed for slitting or shearing?
- Steel coils are processed for slitting or shearing by first unwinding the coil and then passing it through a set of rotating circular blades. The blades cut the steel coil into narrower strips, which are then either rewound into smaller coils (slitting) or cut into individual sheets (shearing). This process allows for the production of various sizes and shapes of steel products for different applications.
- Q: hey... i don't need to change my strings, but i found a set of Bronze acoustic guitar strings by pure tone... i have a few questions on them:can i put them on a steel string guitar? i know i can't put nylon strings on... but i don't see why i can't put bronzethey are light gauze... i have no idea what my current gauze is, but i play in Dropped D tuning... so would the E/D string (6th) be too loose? finally, can you get strings designed to be played in Drop D?any help is apprechiated :D
- Are you talking about a steel guitar or a steel string guitar. Bronze strings won't work properly on a steel/lap steel/electric guitar but hey are designed to be played on an acoustic or acoustic electric steel string guitar. Light gauge strings are OK. However, the low E may be too thin if you tune that down to D. Another thing to consider is that the neck truss rod probably needs to be adjusted slightly if you change string gauge. This procedure is fast and simple if you know what you're doing. You should however leave it to someone else if you don't know how it's done. If you play all the time in drop D, I would probably use a set of medium strings or have a light set and use a heavier low E-string. Personally, I use drop D on my acoustics from time to time. I use light strings and find this to work well for me.
- Q: What does "steel roll number" mean?
- Steel coil number is the specification of steel coil.
- Q: Can steel coils be cut?
- Yes, steel coils can be cut.
- Q: Does anyone know what colour steel is?How hard steel is?The density of steel?Conductivity of steel? (Heat and electricity)Reactivity of steel?Melting and boiling points of steel?And the malleability and ductility of steel?Ive looked all over the net and i cant find anything. Can someone please answer these questions or give me a website?THANKS!
- I'm really finding it hard to believe that you've look all over the net and can't find out anything about steel. A Google search on steel turns up 270 MILLION hits, with the first being good, ole, Wikipedia. A quick glance down the article shows up much of what you want. But keep in mind that that steel is not a single substance. There are many different kinds of steels and each has its own properties. Obviously, steel is a metal, so it is a good conductor of heat and electricity. It can be drawn into wires, so it is ductile. It's hard. It's harder than iron. That's the whole point for making steel. The boiling point and freezing points will depend on the type of steel. But please don't insult us by saying you can't find anything about steel. That simply can't be true.
