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: Hi, I live in the Boston area and I'm trying to find a steel suppler that can provide mild steel for hobby welding. I can go through my job, but we only put in orders every couple of months so it's not very convenient. Also, the few suppliers I've found only sell in bulk. So if anyone knows where I can angle irons, flat bars, sheets, etc... by the piece it would greatly appreciated. Thanks
- They will sell any quantity of metal and even cut it to size - my experience has been that their prices are not wildly out of line for single pieces of full length stock compared to buying singles where you have to buy a minimum. They also may have sizes that ordinary places consider odd. I was looking for 5/8 square 16 gauge and was told it would have to be shipped in from Houston (to Dallas) by my nearest supplier and found it in stock at MetalSM. But check if you get something odd - the 5/8 cost more than 3/4 at both places and MetalSM actually gave me 3/4 but took it back even though I had cut it. Also check the regular steel suppliers in your area as well as retail welders metal supply places.
- Q: how simple is it to take it scrape steel and recyle it. does annybody know the process . i want to do this but first i need some basic information. as far as i know first to melt the steel and in a furness on high heat and than give the shape that customer wants. how right or wrong am i . i want to start on a very small scale.
- Wow, Not sure there is a small scale.....Consider getting a truck,and picking up and collecting scrap metal.You can haul it to your local recycling center, get paid for it ..and let them do the melting and forging. Basics needed to know for this is: Separate Brass, copper, aluminum,cast iron (brake drums,rotors,old sinks and tubs) Car radiators are either copper or aluminum and they pay real well now. There is also a class called SHREDDER this is anything that is not in another category, and literally anything metal, Electrical motors pay good too.
- Q: How can the quality of steel coils be ensured?
- The quality of steel coils can be ensured through a combination of careful selection of raw materials, closely monitored manufacturing processes, and rigorous quality control measures. This includes conducting regular inspections and tests at various stages of production to ensure that the steel coils meet the required specifications and standards. Additionally, implementing proper storage and handling procedures, as well as adhering to industry best practices, can help maintain the quality of steel coils throughout their lifecycle.
- Q: How are steel coils used in the production of electrical wiring?
- Steel coils are used in the production of electrical wiring as a core material for the conductors. The steel coils are typically shaped into a cylindrical form and coated with an insulating material. This helps in providing structural support to the wiring and also enhances its conductivity and durability.
- Q: What are the properties of high-strength steel coils?
- High-strength steel coils possess several distinct properties that make them highly desirable in various industrial applications. Firstly, these coils exhibit exceptional strength, meaning they have a high tensile strength and can withstand significant amounts of force or weight without deformation or breakage. This property allows them to be used in demanding environments or for heavy-duty purposes. Another key property of high-strength steel coils is their excellent resistance to wear and tear. They have a high level of hardness, which enables them to resist abrasion, impact, and other forms of mechanical stress. This makes them ideal for applications where durability and longevity are crucial, such as in construction, automotive manufacturing, and machinery production. Additionally, high-strength steel coils often possess excellent corrosion resistance. They are typically coated or treated with protective materials to prevent rust or other forms of deterioration caused by exposure to moisture, chemicals, or harsh environmental conditions. This corrosion resistance property ensures the longevity and reliability of the coils, making them suitable for applications in marine environments or outdoor structures. High-strength steel coils also offer good formability, meaning they can be easily shaped or bent without losing their strength or integrity. This property allows manufacturers to create complex or custom shapes for specific applications, enhancing their versatility and adaptability. Lastly, high-strength steel coils are known for their light weight compared to other materials with similar strength properties. This low weight-to-strength ratio makes them a preferred choice in industries where weight reduction is crucial, such as aerospace or automotive manufacturing. It allows for improved fuel efficiency, increased payload capacity, and overall cost savings. In summary, high-strength steel coils exhibit properties such as exceptional strength, resistance to wear and tear, corrosion resistance, formability, and light weight, which make them valuable and versatile materials in various industries.
- Q: Why are properties of steel not identical?
- Steel is manufactured to different specs. To match the needs of its intended end use .Tensel strength,Hardness, Corosion resistance etc. The chemical make up will change to suit.
- Q: How are steel coils inspected for thickness using ultrasonic testing?
- Ultrasonic testing is employed to inspect the thickness of steel coils, utilizing a non-destructive method. When conducting this process, a handheld ultrasonic thickness gauge is utilized to determine the thickness of the coil. The ultrasonic thickness gauge emits high-frequency sound waves that travel through the steel coil. These sound waves rebound from the opposite side of the coil, generating an echo. The time it takes for the echo to return to the gauge is measured and utilized to compute the coil's thickness. The gauge comprises a transducer responsible for emitting the sound waves and a receiver that detects the echoes. To ensure optimal acoustic contact between the transducer and the steel surface, the transducer is placed on the coil's surface, utilizing a coupling gel or oil. The transducer releases a brief burst of sound waves, which penetrate through the steel coil and reach the opposite side. If the sound waves encounter any variations or defects in the coil's thickness, they reflect back to the transducer. These echoes are detected by the receiver, and the time between the emission and reception of the sound waves is measured. By utilizing the known speed of sound in steel, the time taken for the sound waves to traverse the coil and return can be converted into a thickness measurement. This enables an accurate evaluation of the steel coil's thickness at different points. Ultrasonic testing is a dependable and efficient method for inspecting the thickness of steel coils. It permits swift measurements without causing any harm to the material, thereby making it ideal for quality control purposes and ensuring compliance with manufacturing specifications.
- Q: Will a 8mm steel ball fired from a 150lbs crossbow kill small game and if so, from how many yards?
- Steel Crossbow
- Q: Im looking at some knives and am wandering if they use good steel one is this case knife and its 54 dollars Do they use good steel or not Iv never had a good experience with Case but am wandering if they use good steel now? if you all have any other recommendations let me hear them I got my Selection from here so any others wont hurt. so basic break down does case use good steel know?
- Case knives are top quality in workmanship. Many have collectors vlaue. I once found an antique four-bladed Case knife is a school yard that had a bone handle. There are basically three types of knives purchased by those who purchase them for practical uses: Pocket knives, made principally for whittling and gneral light use Lock bladed knives Sheath knives I'm not including such novleties as switchblades or throwing knives The latter two types of knives are designed more for outdoor use. Typically they are more duarble and have high quality steel that enables the knife to hold an edge for a longer period of time than a knife made of softer steel. Pocket knives, by contrast, have smaller, thinner blades. Moreover, their steel tends to be a little softer. Comparable brands to Case would include Boker, Old- Timer and Uncle Henry (both Schrade-Walden tradenames), Camillus and others. Overall, I think you would be pleased with a Case knife. Their quality certainly exceeds such brands as Imperial or Queen.
- Q: I would like to know the process of making steel from the mining of ore to the final product. Can anybody offer some help? Either where to look, or the process itself. I would like to have included the different options with which to make steel. Through scrap metal, or iron ore briquettes etc... Thanks.
- I believe you are asking about two vastly different processes. This is science so, if you want a specific answer, you have to ask specific questions. VERY Basically... 1) Pig iron production works by melting iron and pouring it into molds that produce ingots called pigs. 2) fraction distillation separates different substances (typically starting in liquid form) by controlled heating so, since different substances boil at different temperatures, the vapors can be captured selectively.
