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 diffrent Aluminized steel Type 1. stainless steel 409 430?
- Alloy steel is a stainless steel. The differences between the two are the composition of the metal. Alloy steel is steel with usually less than 5% of other elements, like molybdenum, copper, chrome while stainless steel is a steel with at least 10-11% of chromium.
- Q:All of my friends say that if a car made of mostly carbon fiber would crash into a full steel car, or vice versa, the steel car would be DESTROYED and the carbon fiber would drive away, if not, easily repairable.
- At a reasonably high speed, both cars would be undrivable. That's by design, not due to the strength/weakness of the materials. The energy in an impact needs to go somewhere. Cars are designed so the body and the frame will bend and break, reducing the impact on the occupants. If the car is too rigid the chances of the occupants being injured increases. Carbon fiber composites do have a better strength to weight ratio than steel but they're also a lot less dense, so the same volume of material will have a similar strength. The primary benefit to carbon fiber is that for a part of the same strength the carbon fiber part will weigh less than the steel part.
- Q:I have heard using the BRASS casing is the best thing for an AR-15? Should i just use Brass or Steel?
- Two reasonable answers here. But let me say this...I just don't like the idea of steel touching steel at a high rate of speed (like when it's being cycled in and out of the chamber of a rifle). I can't help but feel that some sort of erosion is going to occur to the chamber of the rifle - which obviously isn't a good thing. If it were me, I would stick with firing brass casings only. The only gun I would fire steel casings through would be a cheaper SKS
- Q:I felt that my nylon strings don't sound as good as steel ones. Is it okay that I replace them with steel ones, even if my guitar is classical? Thanks.
- Don't. okorder /
- Q:How are steel coils used in the production of industrial tanks?
- Steel coils are used in the production of industrial tanks as they are rolled and shaped into the desired form, providing the necessary strength and durability for the tank structure.
- Q:What are the common methods of cutting steel coils?
- The common methods of cutting steel coils include shearing, slitting, and laser cutting. Shearing involves using a machine with two blades to cut through the coil. Slitting involves passing the coil through a set of rotating circular blades to create narrower strips. Laser cutting uses a high-powered laser beam to cut through the steel coil with precision.
- Q:I'm going to see Man Of Steel this weekend, and the reviews that I've been hearing aren't that good. I've been hearing that it's this depressing, dark, dramatic film with no humor, loud noises, and action on top of action (which is kind of what I expected from this movie). With that said, I was quite positive that this was what the fans wanted, a more serious Super Man interpretation. I'm ultimately going to judge the movie when I see it, but for now, I have 3 short questions for you:1) What did you think of Man Of Steel?2) Superman Returns got somewhat better reviews than Man Of Steel. Does it seem logical?3) There is a huge fan battle between Man Of Steel and Christopher Reeve's version of Super Man. Which one do you favor?
- I loved the new interpretation in Man of Steel Superman Returns got very poor reviews in the beginning, and as the hatred has worn off and fans have been the only ones voting, the score has moved up. As fond as I am of Christopher Reeves, his version was a touch campy. I much prefer the serious treatment.
- Q:Why do we galvanise steel? Galvanised steel is steel coated with zinc.
- Keeps it from rusting. Zinc doesn't rust like steel does.
- Q:my step father bought a big steel drum grill it has steel sheets (very thin) that go inbetween the flame and the food (closer to the flame) with that there the food will not cook, it does not get hot enough????? please help... what should we do
- that steel plate there is to try to keep the grease dripping of the food from making the grill flame up and burning the food. most all quality grills have something similar. you can take the plate out but your going to be prone to flame ups.
- Q:I bought stainless steel appliances a year ago. I have two kids who like to put their hands all over the fridge and they always leave dirty marks all over it. I bought stainless steel cleaner but it doesn't do a good enough job. Anyone know any other cleaning remedies?
- You can try Stainless Steel wipes. Weiman is a good brand
