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:How are steel coils used in the manufacturing of automotive springs?
- Steel coils are used in the manufacturing of automotive springs as they provide strength, durability, and flexibility required for suspension systems. The steel coils are shaped and formed into the desired spring shape, ensuring optimal performance and handling of the vehicle.
- Q:So I'm trying to decide which is better. I've always had aluminum on my 6 yr old tb gelding as I do hunters on him. He's never had steel on but I've recently moved and the shoer here is more expensive. So is aluminum really worth the extra cash to keep him light on his feet or is steel really not that much different?
- IMO, steel is fine. The only time I've felt that aluminum was important was: 1. A horse with a specific shoeing issue that required an aluminum shoe. 2. A racehorse-- every micro-gram counts. 3. Top level pleasure horses who need a little bit flatter knee. Everything else I've seen did just fine in regular steel shoes.
- Q:Why is steel a stiff material?I'm doing a project on the use of steel in the construction of skyscrapers - and obviously, for the inner steel skeleton of a skyscraper the steel support beams and girders will have to be stiff so that they don't fall apart or the building doesn't shake due to wind or other natural forces.But in my research I've found that steel (mild steel to be more exact) is ductile and malleable, meaning it can be shaped fairly easily. However, how can steel ALSO be stiff - the definition of stiffness is the tendency to withstand bending and stretching - so my question is. How can this material be BOTH ductile/malleable, AND stiff? and why? :)Thank you in advance if anyone takes the time to answer this, would be appreciated - I'll give you 10 points straight away if the answers conclusive
- To say that steel can be bent and shaped fairly easily isn't quite true. It takes multiple tons of force to do so, requiring some very heavy machinery. I think you're confusing a couple of concepts. For example the idea of elastic modulus, versus rigidity Rigidity is the ability of a structure to resist a load. That depends not only on the elastic modulus, but on the size and design of the structure or object. You can build fairly rigid structures out of wood. For example roller coasters. Even though wood has a much lower elastic modulus than steel, meaning that it takes much less force to bend and deform a given sample of wood.
- Q:Are Steel Building Kits really helpful while erecting a steel building?
- Of course yes! Steel building kit is design specific corresponding to the type of steel building required to be constructed or erected. The steel building kit consists of all the necessities needed by the purchaser or the investor. As steel buildings are prefabricated or pre-engineered they are manufactured in factories in various sections and parts which are to be brought to the construction site to be assembled. So in any case they are beneficial :)
- Q:Where do I need hot galvanized steel coils and color coated rolls?
- The use of galvanized steel for color coated steel substrates, except zinc protection, organic coating on the zinc layer up covering the isolation effect, can prevent rusting steel, galvanized steel service life is longer, the coating steel plate galvanized steel long service life is 50%. However, the service life of the color coated plate with the same amount of zinc coating, the same coating and the same coating thickness will vary greatly in different regions and different parts.
- Q:Looking for an insight here into what hiking with steel toe-capped boots would be like, as I saw a nice pair of steel toed magnums that I plan to use for my future hiking (which I will be doing a fair amount of in the future). They seemed fairly comfortable, but I am curious into what others have to say and what might be known of this sort of approach. Thanks in advance.
- Steel toed boots are very heavy compared to hiking boots, after a long hike (especially in rough terrain) the extra weight is gonna tire you out. Steel toes are made for things like construction, or doing a task where extra protection of the toe is needed. So it's not ideal, but whatever floats your boat man (better than wearing tennis shoes). I personally have Converse composite toed boots from my airsofting days and since im too cheap to buy dedicated hike boots, I use it for hiking. Its supposedly made for military use and is much lighter than steel toe. But WAIT!!! lets say you dont have a gun or knife and you run into a pissed off Sasquatch, a steel toe boot too the nutz would do well in puttin the hurt on the dude.
- Q:What is the type of stainless steel used in knifes.
- There okorder / Stainless steel doesn't make the best knife blade. It doesn't sharpen as sharp or hold its edge as well. High carbon steel is better, but it rusts and discolors very easily so it's not as popular. A new thing (actually not new but popular these days) is to use a 'sandwich' of high carbon steel between two layers of stainless. So the actual edge is high carbon steel but the blade looks like stainless. I have some kitchen knives made this way (kind of expensive) and I love them. This same technique was used in Japanese katanas, swords used by samurai warriors.
- Q:did bible stated that steel is coming from outer space. i mean meteor rocks that enter our earth sistem contains the minerals iron.
- First of all, use spell check and read back over what you wrote before submitting it. Second of all steel is a product made from iron through a very complicated scientific process which I will not bother to explain to you at this time. Iron is a naturally occuring substance on our planet which is mined from within the earth like other minerals. Furthermore, I don't recall the Bible saying anything about steel from outer space. What Bible are you reading?
- Q:How are steel coils inspected for formability using forming tests?
- Steel coils are inspected for formability using forming tests by subjecting them to various forming processes such as bending, stretching, or deep drawing. These tests help evaluate the ability of the steel to undergo deformation without cracking or tearing. The formed samples are then inspected for any defects or imperfections, such as surface irregularities, fractures, or wrinkling. This allows manufacturers to assess the quality and suitability of the steel coils for specific applications, ensuring they meet the required standards of formability.
- Q:How are steel coils used in the production of pressure vessels?
- Steel coils are used in the production of pressure vessels as they are rolled into cylindrical shapes, which serve as the main structural component of the vessel. The coils are formed and welded together to create a strong and durable container capable of withstanding high pressures.
