Description of Prepainted Rolled steel Coil for Construction Roofing
Prepainted Rolled steel Coil 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 Rolled steel Coil for Construction Roofing
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.

- Q: How are steel coils used in the production of conveyor systems?
- Steel coils are used in the production of conveyor systems as they are formed into various components such as conveyor belts, pulleys, and rollers. These components provide strength, durability, and flexibility to the conveyor system, ensuring smooth movement of materials along the conveyor and enhancing its overall performance.
- Q: Hello,is it possible to divide an alloy in its own elements? I am particularly interested in Stainless Steel, which is made of Nickel, Chrome and Iron. Do you have an idea of where can I find some more information (blogs, reviews, sites or books)?Thanks for your help
- The iron ,nickel and chromium are (mainly) in solid solution with one another -- all the atoms are completely intermixed on the (FCC)crystal lattice . If you heat stainless steel until it melts , you will simply have a liquid solution of all the components --the components do not separate out. The only practical way to separate the metallic elements would be to make use of their differing reactivities -- re their oxides , nitrides , carbides etc -- and then gradually refine their compounds .
- Q: What are the challenges faced in the recycling of steel coils?
- There are several challenges faced in the recycling of steel coils. Firstly, one of the main challenges is the collection and sorting process. Steel coils are often used in large-scale industries and construction projects, making it difficult to collect and transport them for recycling. Additionally, steel coils may be mixed with other materials, such as plastic or wood, which further complicates the sorting process. Another challenge is the size and weight of steel coils. Steel is a heavy material, and coils can be quite large, making it challenging to handle and process them efficiently. Specialized equipment and machinery may be required to move and separate the coils, which can add to the cost and complexity of the recycling process. Furthermore, the quality of steel coils can vary, which can impact their recyclability. Steel coils may have impurities or contaminants, such as oil or paint, which need to be removed before recycling. These impurities can affect the quality and integrity of the recycled steel, making it less desirable for certain applications. Additionally, the energy and resources required for recycling steel coils is a challenge. The recycling process involves melting down the steel, which requires a significant amount of energy. Furthermore, the transportation and processing of steel coils also consume resources and contribute to carbon emissions, making the recycling process less environmentally friendly. Lastly, the market demand for recycled steel coils can fluctuate, which can impact the viability of the recycling industry. The demand for steel products can vary depending on economic conditions and industry trends. This can make it difficult for recyclers to find buyers for their recycled steel coils, potentially leading to stockpiling or disposal challenges. Overall, while recycling steel coils offers environmental benefits and conservation of resources, there are several challenges that need to be addressed to ensure its successful implementation. These challenges include collection and sorting, handling and processing, quality control, energy and resource consumption, as well as market demand.
- Q: What are the different types of steel coil coatings for heat resistance?
- Heat resistance is achieved through the use of different types of steel coil coatings. These coatings are designed specifically to safeguard the steel surface, preventing it from deteriorating or oxidizing under high temperatures. Organic coatings, such as epoxy, polyester, or polyurethane, are commonly used. They form a protective barrier against heat and prevent the steel from corroding or oxidizing. Organic coatings are typically employed in situations where moderate heat resistance is necessary. Another option is inorganic coatings, made from ceramic or metallic materials. These coatings offer excellent heat resistance and can endure extremely high temperatures. Industries like automotive, aerospace, and power generation frequently utilize inorganic coatings, as their components are exposed to intense heat. Specialized coatings are also available to meet specific heat resistance requirements. Silicone coatings, for instance, exhibit exceptional heat resistance and can withstand temperatures reaching 600°C (1112°F). They find common use in applications like exhaust systems, ovens, and industrial furnaces. Some steel coil coatings may also incorporate additives or fillers to enhance their heat resistance properties. These additions improve the coating's ability to withstand high temperatures and provide superior protection against heat-related issues. In conclusion, a range of steel coil coatings is available for heat resistance, including organic coatings, inorganic coatings, and specialized coatings. The choice of coating depends on the specific heat resistance requirements of the application. Factors such as temperature range, duration of exposure, and environmental conditions must be taken into account when selecting the appropriate coating.
- Q: I have been thinking of buying a knife that says it has damascus steel. The reason for the question is that many people told me that damascus steel does not exist anymore, and that damascus nowadays is fake. Is this true???
- damascus steel it says is made from ore containing either tungsten or vanadium, although most tools I've seen are made from chrome vanadium, it wouldn't be hard in this day and age to get the proper material. Although it DOES say in wikipedia that apparently the technique died out a long time ago due to shortage of the ore. Then it talks about reproduction attempts. So theoretically, yes, it could be the deal deal. But it does refer at the bottom about damascend steel which is made with a different technique, you could be buying one of those. NEXT TIME JUST LOOK UP THE ARTICLE YOURSELF AND READ IT
- Q: How are steel coils used in the production of steel pipes?
- Steel coils are used in the production of steel pipes by being unwound and fed through a series of rollers that shape and weld the steel into a seamless or welded pipe.

- Q: I mean about if I had a piece of metal, how can i decide that's iron or steel?Sorry for bad English.
- There are literally hundreds and hundreds of different commercial steel alloys and a good number of iron alloys so... it depends. Technically, steel is any alloy that is mostly Fe with some amount of carbon. Even if you have access to the necessary lab equipment, CTE (coef of thermal expansion) and specific heat are not very straight forward tests. There are, of course, chemical analysis instruments for measuring C content in steels so, if you really need to know, you can spend money at commercial lab that does these tests. One quick test to judge C content... touch the metal to a grinding wheel, higher C content produces more sparks. To calibrate the way this looks, compare the sparks from a drill bit (usually 1090 steel so 0.9 wt% C) to a steel nail (low C steel). Unfortunately, the difference in sparking between steels with pretty low C content and a piece of iron will not be very dramatic. Of course, iron might mean Cast Iron and, again, there are a good number of commercial cast iron alloys and there are 4 basic types of cast iron alloys and they contain high amounts of C.
