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.
Applications of Prepainted Rolled steel Coil for Construction Roofing
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: What are the factors affecting the price of steel coils?
- There are several factors that can affect the price of steel coils. Some of the key factors include the demand and supply dynamics of the steel market, global economic conditions, raw material costs, production costs, government policies and regulations, currency fluctuations, and competition among steel manufacturers. Additionally, factors like transportation costs and energy prices can also impact steel coil prices.
- Q: What would be a better knife one with damascus steel or one without? Why is damascus steel so special other than the look? And why do some people say high carbon steel is better than regular? mainly though I want to know about the damascus. Thanks, max points to best answer.
- This Site Might Help You. RE: Is a knife with damascus steel better than one with regular steel? or what about high carbon? What would be a better knife one with damascus steel or one without? Why is damascus steel so special other than the look? And why do some people say high carbon steel is better than regular? mainly though I want to know about the damascus. Thanks, max points to best answer.
- 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: How are steel coils used in the manufacturing of suspension springs?
- Steel coils are used in the manufacturing of suspension springs by being tightly wound and then shaped into a helical or spiral form. These coils provide the necessary flexibility and strength required to absorb and distribute the weight and force exerted on the suspension system, allowing for a smooth and stable ride.
- Q: I do a lot of scrapping and would like to be able to separate stainless steel from regular steel. The magnet test doesn't always work since stainless can be magnetic, but what are some ways that I can for sure tell the difference? Or even something like a sound that they make that may help me to tell the difference.
- If you do a lot of scrapping. It is best to get XRF handheld metal analyzer. But they are quite price. Around USD 40.000 upwards! Magnet may only help you sort SUS304/316/201 from SUS430 and metal. But then there might be other alloy. Thus it is best to get XRF analyzer if you feel it is worth the price.
- Q: How are steel coils used in the production of roofing sheets?
- Steel coils are an essential component in the production of roofing sheets. These coils are typically made from high-quality steel, which is known for its durability, strength, and resistance to corrosion. They undergo a series of processes to transform them into roofing sheets. Firstly, the steel coils are loaded onto a machine called a decoiler, which unrolls the coils and feeds them into the production line. This machine ensures a continuous supply of steel for the manufacturing process. Next, the steel coils pass through a series of rollers, which shape the steel into the desired profile for the roofing sheets. These rollers can create various profiles, such as corrugated or standing seam, depending on the specific requirements of the roofing project. After the shaping process, the steel sheets are often coated with protective layers to enhance their durability. This coating can be in the form of zinc or other metallic alloys, known as galvanized or galvalume coatings, respectively. These coatings provide an additional layer of protection against rust and corrosion. Once the sheets are coated, they are typically cut to the desired length and width. This can be done using shearing machines or other cutting tools, ensuring that the roofing sheets are sized correctly for installation. Finally, the roofing sheets are packaged and prepared for distribution to construction sites. They are often bundled together and securely wrapped to protect them during transportation. In summary, steel coils are crucial in the production of roofing sheets. They undergo shaping, coating, cutting, and packaging processes to transform them into finished products ready for installation. The use of steel coils ensures that roofing sheets are strong, durable, and resistant to various environmental factors, making them a popular choice for roofing applications.
- Q: What material is strongest? Human bone, steel, or concrete?
- Takfam is correct, but in the loooong run, concrete will exist for thousands of years after the steel oxidized, deteriorates, and disappears. The ancients compounded concrete even before the Romans (I can't recall but during the time of the Assyrians), and concrete is almost forever.
- Q: Can steel coils be custom-made to specific requirements?
- Yes, steel coils can be custom-made to specific requirements. Steel manufacturers have the capabilities to produce steel coils with various dimensions, thicknesses, and specifications to meet the specific needs of customers. These coils can be customized in terms of width, length, weight, and even surface finish to suit specific applications and industries. Customization can also include variations in steel grade, coating type, and mechanical properties to ensure the desired performance and functionality. The ability to tailor steel coils to specific requirements allows for optimal utilization in various sectors such as automotive, construction, appliances, and manufacturing, among others.
- Q: Monopolistic competition means all of their products are identical like things in supermarket like milk. There are no high barriers to entry. Oil and steel are all same in all industries.
- While oil and steel may seem to be all the same, they are really not. There are many different grades of crude oil and many different types of steel.
