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: 7850kg/cu.m density is typical for all type of steel? like reibar, I- beam and so on
- 90% of the steels used today are plain mild carbon steels consisting of iron with less than 1% carbon content and as such have a density of about 7750 kg/cubic meter. Some special steels which have a significant percentage of alloying elements such as chrome or manganese or other elements will have greater density bringing the steel up to about 8000 kg / cubic meter. There are a greater many factors influencing the exact density of a steel. Even for steels of exactly the same content of iron , carbon and other alloying elements, there may be a difference ( very small mind you ) in density due to work hardening. The difference in this case is due to movement of dislocations which become locked in the grain boundaries and this forms a more dense crystal structure. For this same reason, the theoretical density of steel (which does not take into account dislocations) is greater than the measured density of steel.
- Q: PLEASE PLEASE PLEASE!!!!!!!! HELP MEEEEEEEE!!!!!!! I need to know how can i prevent steel from rusting when it is exposed to water or salt water or vinegar. PLEASE TELL ME A LOT OF WAYS THAT I COULD PREVENT IT!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!
- steel that will not rust is called Stainless Steel. Exposure to oxygen causes rust. In stainless steel is heated and all the oxygen burnt out of it. I would go with a high grade (there are multiple grades) of stainless steel
- Q: What are the different methods of tension leveling for steel coils?
- There are several methods of tension leveling for steel coils, including roller leveling, stretcher leveling, and temper leveling. In roller leveling, the coil passes through a series of rollers that apply pressure to remove the internal stresses and flatten the material. Stretcher leveling involves stretching the coil beyond its yield point to remove the unevenness and then allowing it to spring back to a flat state. Temper leveling uses heat treatment to relieve the internal stresses and bring the coil to a flat condition. These methods provide different ways to achieve a level and flat surface for steel coils.
- Q: Where can you buy a steel polearm in a shop or if someone has a file in Scania than can you sell me one ill buy it for 150k my account is tonypark500
- you can buy it at the free market, but they worth more than 150k they sell for about 1m so good luck with getting polearm.
- Q: I live in Dubai. I want to make a damascus steel sword and have no idea where to get the steel or what sort of steel I should get.First to adress the access of my steel...I need to get some low carbon and high carbon steel for the Damascus....what sort of steel is recommended for this? Also where would I be able to get my hands on it (Internet options e.g websites or locations)THANKS

- Q: How are steel coils used in the production of metal signs?
- Steel coils are used in the production of metal signs by being processed through a series of steps such as cutting, shaping, and welding. The coils are uncoiled and cut into the desired size and shape for the sign. Then, they are shaped using various methods like bending or rolling to achieve the desired design. The coils may also undergo welding to join different sections or add additional components to the sign. Overall, steel coils provide the raw material necessary for creating durable and sturdy metal signs.
- Q: What are the end uses of galvanized steel coil? What is the market like for this raw material? Would something like this be expensive?Also can you explain: PPGI.And the following specifications; what do they mean/represent?Required Composition :Thickness- 0.23mmCarbon- Max. 0.01%Manganese- Max. 0.20%Phosphorous- Max. 0.05%Sulphur- Max. 0.01%Silicon- ABT. 2.80 - 3.50%CRGO Quality- Prime QualityThanks
- Steel coil is the name given to thinner sheet steel when it is manufactured - it comes out of the machine and is formed into a coil for ease of handling storage and transportation. Thin sheet steel is used for plenty of stuff. It can be slit (cut) into thin strips as well as just cropped and used at one of the standard lengths x widths it leaves the mill. There is a big market for this material. It is used in many construction and engineering applications for things like ducting, boxes, gutters, down pipes, flashings, panels, car bodies etc., anything made of thin steel Galvanising is a flash coating of zinc which improves it's corrosion resitance. Cost wise it is a relatively cheap material. The chemical composition of steel varies, it is mostly iron but has various other elements added or present as impurities that change it's characteristics, depending on the end use. These additional elements can be selected to give better weld ability, hardness, tensile strength, corrosion resistance, flexibility and so on. In many applications excess of these chemicals is undesirable. For example sulphur and carbon are generally better at lower levels. The chemical composition data is contained in a material data sheet and expressed as a percentage of the chemical present and which gives the composition of a particular batch of steel, allowing it to be selected for particular applications and traced for quality assurance purposes. The list you have there shows presence and quantity of other elements in a particular batch of coil. The thickness is 0.23mm, quite thin.
- Q: I'm in the process of buying a new car, and wondering if there are more benefits from Aluminum tire rims over Steel. Aluminum wheels cost more, but you'd think that steel would last longer. Are Aluminum wheels just for looks?
- aluminum is lighter , alot of performance cars use them to trim unsprung weight from the wheels ... steel wheels are cheaper but u have to put hub caps on them ... eeeeeuuuuueeewww!!!!!
- Q: What are the different testing methods used for steel coils?
- There are several testing methods used for steel coils, including visual inspection, dimensional measurements, hardness testing, tensile testing, bend testing, and surface quality analysis. These methods help ensure the quality and compliance of steel coils with the specified standards and requirements.
- Q: Personally, I like Steel Cage matches to end in pinfalls. One of the biggest selling points of a Cage match is that it is to keep the competitors in and keep others out; essentially ensuring that it's a 1 on 1 match. As a result, I believe that pinfalls or submissions are important - but I know there's a lot of people that believe cage matches should only end in escape. What do you think??
- Escape. It is more fun to watch and gets fans adrenaline pumping
