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.

We have established the international advanced quality management system，every link from raw material to final product we have strict quality test；We resolutely put an end to unqualified products flowing into the market. At the same time, we will provide necessary follow-up service assurance.
- Q:Corten steel tends to overheat in hot environments? (for example copper heats up under the sun)
- Bill summed it up pretty quick and provided a link. For some reason you are focusing on the copper content when it really is insignificant in the overall picture of the sun hitting its surface. If you could elaborate more, maybe we could offer a better answer.
- Q:What are the common coil processing methods?
- Some common coil processing methods include slitting, cut-to-length, leveling, and blanking. These methods are used to transform large coils of metal into smaller, more manageable sheets or strips for further manufacturing processes.
- Q:doesnt steel rust?
- Iron mixed with other metals:
- Q:I have a steel string, Yamaha acoustic guitar that I am learning to play at home. But at school I use a rented nylon string guitar. I like the feel of the nylon strings better then the steel strings and i was wondering if i can just switch strings or if i should just get another guitar. Can anyone help?
- No, okorder /... You will want a full size or possibly a 3/4 size guitar. A 3/4 size guitar is a little smaller and will be closer in neck width to a steel string guitar. I used one like that when I started out playing when I was young. Avoid the cheap ones on Amazon that only cost $30-$50.
- Q:which metals have a higher density than steel? and how does the density compare to steel( example: tungsten carbide is 2x [i think] more dense than steel.)
- Stainless steel 7480 -8000 kg/m^3 Brass 8100 -8250 Cobalt - 8746 Copper 8930 Gold 19320 Lead 11340 Mercury 13593 Molybdenum 10188 Nickel 8800 Platinum 21400 Plutonium 19800 Silver 10490 Tungsten 19600 Uranium 18900
- Q:How are steel coils used in the production of metal partitions?
- Steel coils are used in the production of metal partitions by being processed and cut into sheets, which are then formed and welded together to create the partitions. The steel coils provide a strong and durable material that can withstand the rigors of partition construction and installation.
- Q:Does anyone know what colour steel is?How hard steel is?The density of steel?Conductivity of steel? (Heat and electricity)Reactivity of steel?Melting and boiling points of steel?And the malleability and ductility of steel?Ive looked all over the net and i cant find anything. Can someone please answer these questions or give me a website?THANKS!
- I'm really finding it hard to believe that you've look all over the net and can't find out anything about steel. A Google search on steel turns up 270 MILLION hits, with the first being good, ole, Wikipedia. A quick glance down the article shows up much of what you want. But keep in mind that that steel is not a single substance. There are many different kinds of steels and each has its own properties. Obviously, steel is a metal, so it is a good conductor of heat and electricity. It can be drawn into wires, so it is ductile. It's hard. It's harder than iron. That's the whole point for making steel. The boiling point and freezing points will depend on the type of steel. But please don't insult us by saying you can't find anything about steel. That simply can't be true.
- Q:I also heard Stainless holds up better againts rust, blue steel needs more care.
- They have different properties. Bluing on steel is a surface treatment that helps inhibit rust, but doesn't prevent it. It will wear off with use over time, but can be redone. Stainless steel refers to a particular type of steel alloy, usually incorporating nickel and chromium, that is highly resistant to rust on its own, so doesn't need a surface treatment. Because the steel itself is what is rust resistant, that property can't wear off. All other things held equal, the carbon steel that bluing is typically applied to tends to be slightly more rigid and brittle than stainless steel. It may hold an edge better than stainless. In most applications, those differences are small enough not to matter for practical purposes. For example, both knives and guns are made with blued steel and stainless steel. Which a person gets is usually a matter of preference (unless you're, say, a professional restaurant chef whose knives have to hold a fine edge through constant hard use).
- Q:How are steel coils used in the production of wind turbines?
- Steel coils are used in the production of wind turbines to construct the tower and support structures. The coils are shaped and welded to create the tower sections, providing strength and stability to support the turbine's blades and nacelle. Additionally, the coils are also used to create the structural components, such as the base, for the turbine. Overall, steel coils play a crucial role in the manufacturing process of wind turbines, ensuring their durability and structural integrity.
- Q:How are steel coils used in the production of roofing systems?
- Steel coils are used in the production of roofing systems as they are formed into sheets or panels that are then shaped, cut, and fastened to create durable and weather-resistant roofs. The coils provide the raw material for manufacturing various components of the roofing system, such as metal tiles, standing seam panels, or corrugated sheets, which offer excellent strength, longevity, and protection against harsh elements.
