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 bought a steel pendant on eBay, but it turned out to be too shiny.I've read on a couple forums that if I leave it soaked in urine for 2 days, it will get duller.Now, if it really does get duller, will the pendant get rusty afterwards?So is the shiny surface the only thing that prevents it from rusting?Any simple, non-urine ideas on how to make it duller are welcome too.Thanks!
- Stainless steel will rust under proper conditions. I live on a boat on salt water, trust me. If the urine works it won't be prone to rusting any more than before. It's not the shine that inhibits rusting with stainless steel, it the % of carbon in the steel, compared to regular steel. IF the urine works it's because it is acidic (a mild acid). Wash it with a small brush and some baking soda to neutralize the acid when your done. A much stronger acid would be swimming pool acid. (Muriatic acid) but be careful you might test a spot with a Q tip on the back. If you try Muriatic acid it would take seconds.Then wash in baking soda water to remove all acid.. SS
- Q:What are the different types of steel coil edge trimming methods?
- There are several different methods used to trim the edges of steel coils, including slitting, shearing, and laser cutting. Slitting involves using circular blades to cut the edges of the coil, creating narrower strips. Shearing is a process that uses a straight blade to cut the coil edges. Laser cutting is a more advanced method that uses a laser beam to precisely trim the edges of the steel coil. These methods are used depending on the specific requirements of the steel coil and the desired end product.
- Q:Are steel buildings more durable than concrete building?
- Not necessarily as most concrete buildings are steel re-inforced anyway. As for durable, if talking time based, no, because steel will corrode and concrete will not. The good thing about concrete is that it has good load bearing capability over wide spans whereas steel will bend unless properly supported. Concrete is cheaper also....
- Q:rust is not a issue. i was looking a D2 steel but heard story's of it chipping and breaking
- INFI steel used by Busse Combat is probably one of the best steels around right now, but the price reflects that. The heat treat is a HUGE part of the toughness of a steel. A good heat treat can make a bad steel a good one, or a good one a great one. I personally prefer 1095. It's a good ole tool steel on the lower end of the price scale and it holds up well. I've always had good experiences with 1095.
- Q:How are steel coils unloaded from a truck or ship?
- Steel coils are typically unloaded from a truck or ship using specialized equipment such as cranes, forklifts, or coil lifters. The coils are carefully lifted off the truck or ship and then placed onto a designated area in the storage yard or warehouse using the appropriate machinery.
- Q:doesnt steel rust?
- Stainless steel is regular steel that has had nickel added in the manufacturing process. Because of the nickel it prevents rust.
- Q:What are the different types of steel coil packaging materials?
- Some common types of steel coil packaging materials include wooden crates, steel frames, plastic strapping, stretch wrap, and steel bands.
- Q:What are the common uses of stainless steel coils?
- Stainless steel coils are commonly used in various industries such as automotive, construction, manufacturing, and food processing. They are utilized for making a wide range of products including kitchen appliances, metal containers, piping systems, heat exchangers, and architectural components. The high corrosion resistance, durability, and aesthetic appeal of stainless steel make it an ideal material for these applications.
- Q:How are steel coils used in the production of steel pipes?
- Steel coils are used in the production of steel pipes by being unwound and fed through a series of rollers that shape and weld the steel into a seamless or welded pipe.
- Q:density of mild steel (MS) is 7850 KG per metre cube , but i want to know the density of stainless steel
- Stainless steels are the most dense, coming in at 8000 kg/m3. Though the densities vary, The answer is 8000 kg/m3. 301 stainless density values seem to vary according to the supplier data sheets, from 7.88 g/cc, (AK Steel) to 8.03 g/cc, (Allegheny Ludlum)
