Description of Aluminum Zinc 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 Aluminum Zinc Rolled Coil for Construction Roof
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 Aluminum Zinc Rolled Coil for Construction Roof
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.

3. How to guarantee the quality of the products？
We have established the international advanced quality management system，every link from raw material to final product we have strict quality test；We resolutely put an end to unqualified products flowing into the market. At the same time, we will provide necessary follow-up service assurance.
- Q: What are the common coil loading and unloading procedures?
- Common coil loading procedures involve using cranes or forklifts to lift and position coils onto trailers or flatbed trucks. The coils are typically secured using straps, chains, or coil racks to prevent shifting during transportation. During unloading, the same equipment is used to carefully lift and remove the coils from the truck, ensuring safety and stability throughout the process.
- Q: I bought this Brinks pad lock and it says boron steel on the lock. I was just wondering what exactly is boron steel and how hard/tough is it?
- Boron steel is rather hard, it is by no means titanium, but certainly better than mild steel. However, as with all metals, hardness is inversely proportional to flexibility, meaning that a good solid whack with a sledge hammer could crack your lock.
- Q: benchmade mpr with m390 steel knife. Is it better than d2 s30v or 154cm steel?
- From what I read M390 is relatively wear resistant, with very high stain resistance and good toughness. It is quite hard to qualify steel as better than other steel because it depends on many factors. E.g. for a small folder designed for delicate cutting D2 at high hardness would perform better, but if the environment is corrosive, like saltwater then M390 would be better. I'm not so sure about using stainless steels in large chopping style knives, but I've seen M390 used for them as well. Obviously hardness had to be lowered, which reduces edge holding ability, especially at low angles. Overall, it's a good steel, but if it will outperform S30V or D2 or 154Cm depends on heat treatment and blade geometry, knife designed use, etc.
- Q: What are the different types of steel coil welding methods?
- There are three main types of steel coil welding methods: butt welding, lap welding, and flash welding. Butt welding involves joining two ends of steel coils by aligning them and welding them together. Lap welding, on the other hand, involves overlapping the ends of the coils and welding them together. Flash welding is a method where the ends of the coils are placed in contact with each other and a high electric current is passed through them to create a weld.
- Q: I am using mild steel wire (very thin and bendable) for an art project, and would like to know if using a soldering torch is effective enough to get the job done. Or do I have to use a butane torch to heat the metal?BTW, is it better to use soft or hard solder?
- You can indeed by using the correct flux as normal soldering fluxes as used by plumbers will not work. I believe to solder steel it requires an acid flux which will corrode copper so when its done make sure its well cleaned afterwards and if possible apply a corrosion proofer afterwards ie paint or even petroleum jelly. I am curious as to why you would want to solder wire to a steel nail.
- Q: What are the dimensions of steel coils used in the furniture industry?
- The dimensions of steel coils used in the furniture industry can vary depending on the specific application and requirements of the furniture manufacturer. However, typically, steel coils used in the furniture industry have dimensions ranging from 0.20mm to 3.00mm in thickness and 600mm to 2000mm in width. The length of the coils can also vary, but it is commonly around 1000mm to 3000mm. These dimensions allow for flexibility in shaping and forming the steel coils into various furniture components such as frames, springs, and structural supports.
- Q: How does adding carbon to Iron make it stronger? How does steel look the molecular structure in comparison to Iron? looking for a very scientific answer =]
- Cast Iron' is typically brittle, while 'Maleable Iron' has a small percentage of carbon which allows it to be hammered and formed. Steel is an alloy that consists mostly of iron and has a carbon content between 0.2% and 2.1% by weight, depending on the grade. Carbon is the most common alloying material for iron. Steel is a crystalline structure of iron molecules interspersed with carbon molecules. This is properly known as cementite. The hardness and malleability of steel depends not only on the carbon content, but on how the carbon and iron molecules are arranged to one another. Internal stresses in the steel's crystalline structure will increase or decrease depending on the temperature it is subjected to and the rate at which molten steel is cooled. This 'tempering' can increase the strength of the steel at the expense of brittleness.
- Q: is cold roll or hot roll mill roller is cast steel? or cast iron?
- another name is Grey iron, come from groups of ferrous alloys
- Q: How are steel coils used in the manufacturing of electrical equipment?
- Steel coils are commonly used in the manufacturing of electrical equipment as they serve as a key component in transformers and motors. These coils are typically made of high-quality steel and are tightly wound to create an electromagnetic field when an electric current passes through them. This allows for efficient power transmission, voltage regulation, and electromagnetic induction, which are essential functions in various electrical devices.
- 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.
