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: I have been searching on pots and pans, how can I find out if it's really stainless steel, someone told me if a magnet sticks to it it's real stainless steel is this true?
- if a magnet sticks to it that means it's a cheaper metal coated with stainless steel. if it's an appliance you're buying, look on the reciept. real stainless steel will actually say it. the coated stuff will just say stainless leaving out the steel.
- Q: I was cutting a sheet of steel with an angle grinder when suddenly the rate at which the blade was cutting slowed way down. I tried a few different things, and turned off the tool and looked at the blade. It didn't look damaged, but it definitely was not cutting as quickly. I thought either I had hit a harder section of steel (is that possible? It looked pretty uniform) or the blade had lost it's abrasive quality or something. Also, before this happened I had accidentally cut into the wooden sawhorse that was holding up the steel sheet, but I've done that before with no problem. After a short while the problem fixed itself and the rate of cutting went back to a fast normal. Anyone know why this happened?
- Sounds like the abrasive surface got blinded, coated with something that prevented the abrasive particles from touching the steel. It is possible to have vastly different hardnesses in a single piece of steel. Case hardening, carburizing, induction hardening, heat affected zone from welding, differences in work hardening, and presence of inclusions are some of the things that can create hardness variation within a single piece. But... sounds like you are working with a sheet which is unlikely to have any of these conditions. So... it was probably the grinding disk
- Q: How many inches of steel can an AK47 using 7.62x39mm rounds penetrate through?
- A very thin layer of steel. I've fired the AK47 at tanks, ofcourse that wouldn't penetrate but it's not going to penetrate anything crazy. It is a strong Assault Rifle don't get me wrong.
- Q: How are steel coils coated?
- Steel coils are coated through a process called coil coating, where the steel is cleaned, treated, and then coated with a protective layer using techniques such as roll coating or spray coating.
- Q: How many types of steel buildings are there?
- There are a number of designs which can be used to create different types of steel buildings as per the demands of the buyer or an investor. he various kinds of that can be constructed using steel are Homes, Hangars, Agriculture and Farm buildings for storage, Garages and Storage sheds, Open air sheds,, Barns, Arenas and stadiums, Automotive buildings with overhead doors and flexible framed openings, Religious buildings such as Churches and Temples, etc.
- Q: Is steel easier to weld?Which is more brittle/less flexible?
- Yes you can, but you really dont want to. Aluminum conducts heat better than steel so the weld would not cool evenly and would be brittle. You would be better off using a bracket or bolt straight on.
- Q: What are the different methods of oiling steel coils?
- There are several methods of oiling steel coils, including applying oil by roll coating, using a spray system, or immersing the coils in an oil bath.
- Q: Are steel or graphite clubs better?
- If its for your bf, i would buy steel. Most guys prefer steel because it is more accurate and it think every guy on the pga tour uses steel shafted irons. Steel also usually costs less, which helps. Neither one is better, its just a matter of personal preference.
- Q: What are the different methods of coil leveling?
- The different methods of coil leveling include roller leveling, stretcher leveling, and temper leveling.
- Q: How are steel coils protected against corrosion?
- Steel coils are protected against corrosion through a process known as galvanization, where a layer of zinc is applied to the surface of the steel. This zinc coating acts as a barrier, preventing the steel from coming into direct contact with moisture and oxygen, which are the main causes of corrosion. Additionally, other protective measures such as painting or coating the steel with anti-corrosion materials may also be employed to further enhance its resistance against corrosion.
