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 packaged for shipping?
- Steel coils are typically packaged for shipping by placing them on wooden or steel pallets, securing them with steel bands or straps, and covering them with protective wrapping such as plastic or waterproof paper. This packaging ensures the coils remain stable, protected from corrosion, and are easy to handle and transport.
- Q:What is steel made of? What are the elements other than iron?
- mainly steel made of Iron and carbon and treated in a proper process to become hard you can add some kind of other elements to get your desired proparty as Chromium,, nickle.. Cupper,, Berelyium,, Vanadium
- Q:7850kg/cu.m density is typical for all type of steel? like reibar, I- beam and so on
- 90% of the steels used today are plain mild carbon steels consisting of iron with less than 1% carbon content and as such have a density of about 7750 kg/cubic meter. Some special steels which have a significant percentage of alloying elements such as chrome or manganese or other elements will have greater density bringing the steel up to about 8000 kg / cubic meter. There are a greater many factors influencing the exact density of a steel. Even for steels of exactly the same content of iron , carbon and other alloying elements, there may be a difference ( very small mind you ) in density due to work hardening. The difference in this case is due to movement of dislocations which become locked in the grain boundaries and this forms a more dense crystal structure. For this same reason, the theoretical density of steel (which does not take into account dislocations) is greater than the measured density of steel.
- Q:What are the different methods of forming steel coils into sheets?
- There are several methods of forming steel coils into sheets, including hot rolling, cold rolling, and annealing. Hot rolling involves heating the steel coils and passing them through a series of rollers to reduce their thickness and shape them into sheets. Cold rolling, on the other hand, does not involve heating the coils and instead uses pressure to shape them into sheets, resulting in a smoother and more precise finish. Annealing is a process that involves heating the steel coils to a specific temperature and then slowly cooling them, which helps to relieve stress and improve the material's ductility before it is formed into sheets.
- Q:What types of steel are used in steel coils?
- There are various types of steel that are commonly used in steel coils, including carbon steel, stainless steel, and alloy steel.
- Q:I moved into a house which has a steel front door.When I touch the door it feels very cold to the touch in the winter.There is a storm door also and the weather stripping looks good.Cold air from the door is entering the lower level.The house is about 20 yrs old.
- Now a days crime has increased a lot, so we have to take protection and when the protection came to our house there came steel doors. The best ever protection in our houses. Source - www.scoop.it/t/qualitas-steel-doors
- Q:Can steel coils be coated with scratch-resistant materials?
- Yes, steel coils can be coated with scratch-resistant materials. These materials can provide a protective layer that minimizes the risk of scratches and damage to the steel coils during transportation, handling, and storage.
- Q:Theirs this two handed chinese sword on amazon with a forged combat steel blade and i was wandering if it means combat steel in the same sense that tempered carbon steel can be used?
- Combat steel? No such thing... Combat steel is a commercial product... not a true type of steel, since there is no ASTM grade of combat steel... And carbon steel is a WHOLE list of different types of steel, whether it's tempered or not... The company does not provide what steel specifications it has other than combat steel... So my best guess is that it's an alloy of 1095 or 301 spring tempered... both are resilient to snapping and fatigue, and common in modern swords... however, they do not hold an edge very well and are prone to rusting...
- Q:Steel resist tension. Then why we provide steel in compression zone ?
- There are several reasons to add compression steel. Keep in mind, supported steel (meaning it can't buckle) resists compression as well. Compression steel helps reduce long term deflections. Concrete creeps under sustained loads. Steel lessens the compression, meaning less sustained compressive stress to cause creep deflection. It makes members more ductile. Since the steel takes some of the compressive stress, the compression block depth is reduced, increasing the strain in the tension steel at failure, resulting in more ductile behavior (the moment at first yield remains largely the same with compression steel added, but the increase in capacity after yield is significant). Compression steel insures that the tension steel yields before the concrete crushes, meaning it helps change the failure mode to tension controlled. It makes beams easier to construct. With bars in the top and bottom, you have longitudinal reinforcement in all 4 corners of the shear stirrups to keep them in place when pouring the concrete. Also, for continuous members, its often easier to run your negative moment steel the full length of the beam rather than trying to cut it off in the positive moment regions. Serviceability concerns. You're going to end up putting steel in that region anyway to for temperature and shrinkage.
- Q:How are steel coils used in the manufacturing of defense equipment?
- Steel coils are used in the manufacturing of defense equipment as they provide strength, durability, and resistance to impact and stress. These coils are typically used to fabricate various components, such as armor plates, vehicle frames, and missile bodies, which are crucial for the protection and functionality of defense equipment.
