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 is the maximum temperature that steel coils can withstand?
- The maximum temperature that steel coils can withstand depends on the specific grade and type of steel being used. However, in general, steel coils can withstand temperatures up to around 1,300 to 1,500 degrees Celsius (2,372 to 2,732 degrees Fahrenheit) before they start to lose their structural integrity and develop deformation or other forms of damage.
- Q: In the game RuneScape, the concept of the fictitious metal, Rune has intrigued me. On an equal area AND weight basis (with a possible 10 lb exception) what metal is 256% stronger than steel?
- Alumuniom so that, it is used in Rockets and planes another feature for Alumuniom, that it can bear a huge amount of heat.
- Q: What are the common coil tests performed for quality control?
- The common coil tests performed for quality control include dimensional checks, visual inspections, mechanical property testing, surface defect examinations, and chemical composition analysis. These tests ensure that the coils meet the required specifications and standards, ensuring their quality and suitability for various applications.
- Q: How are steel coils used in the production of steel wire?
- Steel coils are used in the production of steel wire by being unwound and fed into a wire drawing machine. The coils provide a continuous and consistent supply of steel, which is passed through a series of dies to reduce its diameter and increase its strength. This process is repeated multiple times until the desired wire diameter is achieved.
- Q: How can I tell the wear resistance, strength, ect from the name of the steel?how could I tell the difference between 420 and 440 steel. what does the HC in 420 HC steel mean? what do the numbers and letters in s30v steel mean?
- Larry gave a good answer. As for the HC, it means High Carbon.
- Q: How are steel coils coated?
- Steel coils are coated through a process called coil coating, where the steel is cleaned, treated, and then coated with a protective layer using techniques such as roll coating or spray coating.
- Q: What are the dimensions of steel coils used in the construction equipment industry?
- The dimensions of steel coils used in the construction equipment industry can vary, but they are typically around 48 to 72 inches in width and have an outer diameter of 60 to 80 inches. The weight of these coils can range from 5,000 to 30,000 pounds.
- Q: Which one is stronger steel or metal ( for bow and arrows) please answer I need it for a book I'm writing
- Metal includes steel, as well as thousands of other metals and alloys. In other words, steel IS a metal. So your question is meaningless, sorry.
- Q: How do steel coils perform in high-temperature applications?
- Steel coils perform well in high-temperature applications due to their excellent heat resistance and structural stability. The high melting point of steel allows it to maintain its strength and shape even at elevated temperatures, making it suitable for various industries such as automotive, construction, and manufacturing. Additionally, steel coils can withstand thermal expansion and contraction without warping or deforming, ensuring reliable performance and durability in extreme heat conditions.
- Q: Is there a chemical that can be applied (spraid, brushed, adhere) to a steel surface to decrease the heat conductive properties of the metal (so it doesn't heat up as quickly)?Thanks in advance!
- There is, but I don't know what it is made out of. It is probably some fireproof, foam material which acts like insulation. I doubt it is designed to resist abrasion however. Most things which adhere to metal surfaces are not flameproof, and those which do resist fire are not good insulators. For example, the ceramic coating of appliances like stoves and washing machines adhere very well and are fire resistant, but do not insulate. It was the failure of the steel insulation which caused the collapse of the world trade centers. The impact of the airplane tore away all the insulation on the supporting struts of the building and then the fire caused the steel to soften and break. Steel was once insulated by wrapping it in asbestos cloth and then applying plaster over this to form a shell. It did not actually adhere to the steel but it did insulate it, and was fireproof. However asbestos is a cancer hazard and a lot of old buildings are being stripped of their asbestos as a safety precaution. The asbestos can be replaced with fiberglass which is usually duct taped together.
