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: Measures to prevent cold rolling of packaged cold rolled steel coils? Who can give some professional opinions oh?
- In order to prevent rusting in the process of storage or transportation of steel roll, steel mills generally take the following packing: inner gas antirust paper wrapped with tape wrapped in plastic film sealing, intermediate, involute cardboard seal lining, cardboard corner, with iron and steel outer package corner protector, strapping fixed. If the inner package seal, so the steel coil is sank into the water, will not rust out.
- Q: if steel is heated from room temperature (20c) to (500c) what would be the change in density?coefficient for linear expansion of steel 12x10^-6 k density of steel 7800 kg
- First you have to convert the coefficient of linear expansion to a coefficient of volumetric expansion. Multiply the coefficient of linear expansion by 3: Coefficient of expansion of steel,β:12E-6/°K x 3 = 36E-6/°K Difference in temperature: 480°K ΔV = VoβΔT ΔV = Vo x (0.000036) x 480 ΔV = 1m? x 0.017 ΔV = 0.017m? Originally, the steel was at 7800 kg/m? Now, the steel was at 7800 kg/ 1.017m?, or 7670 kg/m? Change in density = 7670 - 7800 = -130kg/m?
- Q: What are the different types of steel coil loading and unloading methods?
- There are several different types of steel coil loading and unloading methods, including overhead crane loading and unloading, forklift loading and unloading, coil car loading and unloading, and conveyor loading and unloading. Each method has its own advantages and suitability depending on the specific requirements and constraints of the steel coil handling process.
- Q: does anyone out there know where to get a good deal on a pedal steel guitar? i am from northern indiana and i'm willing to travel some if i have to.i am just getting into pedal steel guitar and i really don't have any idea what i need. i don't know how to play a guitar (i do know how to play the piano and the drums) at all but i want to learn to play the pedal stell guitar and i can't do that without getting one first so, if anyone can help me out i would greatly appreciate it! :o)
- Pedal steel guitars are a challenge to learn but they're a great instrument. More, even a starter pedal steel is going to run you $800 or so. Elderly Instruments in Lansing, Michigan sells a Carter brand starter pedal steel for $795 which is about as low as I've seen new ones. It has 3 foot pedals and 4 knee levers so it's nicely equipped. From northern Indiana it's not that far I would think. Good luck.
- Q: What are the different coil coatings available for steel coils?
- There are several different coil coatings available for steel coils, including polyester, silicone modified polyester (SMP), polyvinylidene difluoride (PVDF), plastisol, and epoxy. Each coating has its own unique properties and advantages, such as durability, weather resistance, and color retention, allowing for a wide range of applications in various industries.
- Q: What are the common surface treatments for steel coils?
- Common surface treatments for steel coils include galvanizing, which involves applying a layer of zinc to protect against corrosion; painting, where a layer of paint is applied for aesthetic purposes or to provide additional protection; and chromating, which involves applying a thin layer of chromium to enhance corrosion resistance and improve paint adhesion.
- Q: How are steel coils inspected for paint adhesion?
- Steel coils are inspected for paint adhesion through various methods such as visual examination, tape test, and cross-cut adhesion test. These tests involve visually inspecting the surface for any paint defects, applying adhesive tape to check if the paint adheres properly, and making cross-cuts to assess the adhesion strength.
- Q: I was wondering if anyone knew the grade/type of steel for this product. I'd like to use it as stock for a knife blade, but would like to know the specs so I can determine if it is suitable and, if so, how best to heat treat it.Thanks.PS: I know it isn't stainless, but that leaves a lot of other steel types.

- Q: I do a lot of scrapping and would like to be able to separate stainless steel from regular steel. The magnet test doesn't always work since stainless can be magnetic, but what are some ways that I can for sure tell the difference? Or even something like a sound that they make that may help me to tell the difference.
- Stainless steel uses chromium in its mixture to thwart the affects of corrosion. General steel, or carbon steel, is generally almost completely iron and is used for far greater applications than stainless steel. Stainless steel is used mostly in kitchen appliances, utensils, etc... The best thing I can come up with is to find a way to measure the chromium content of the steel you are looking at. If it's around 3% chromium, it's probably standard steel. If it's somewhere between 10-15% chromium it's probably stainless steel (or even 4% plus). I can't tell you a fast and quick way to test the steel because from my research, it appears there are as many grades and allows of steel as there are uses for steel! There is one test I've seen for home testing surgical steel which is a higher grade stainless steel, that is to put scotch tape on one section of material then soak it in water for a 24 hour period, then let it air dry for 24 hours. You remove the tape and lightly polish the exposed areas to see if there was any discoloration or pitting on the exposed area. This test is mainly for surgical steel jewelry, however stainless steel is supposed to resist rusting more than standard steel, hence it might work for other steel types as well. You may have to read some of the other links below to get some other ideas on how you can test steel to see if it is stainless.
- Q: I saw this really pretty ring online and it was made of steel. Is this a good ring? If I were to wash my hands with it on, would it rust and turn my finger green?
- Steel rust is brown not green! Very much expected to be of one type of stainless steel, and you should have no problem.
