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.

- Q: What are the different types of steel coil finishing machines?
- There exists a variety of steel coil finishing machines, each designed to accomplish specific tasks and attain desired outcomes. Some commonly encountered types are as follows: 1. Slitting Machines: These machines are employed to divide large steel coils into narrower strips of desired widths. They comprise a set of circular blades that cut through the coil as it progresses through the machine, resulting in multiple smaller coils or strips. 2. Cut-to-Length Machines: These machines are utilized to cut steel coils into specific lengths. They can be programmed to execute precise cuts at predetermined lengths, thereby ensuring accuracy and consistency. 3. Recoiling Machines: Recoiling machines are deployed to rewind steel coils into tightly wound, compact rolls. They are typically used to create smaller coils from larger ones or to recondition coils that have become loose or damaged. 4. Edging Machines: Edging machines serve the purpose of removing excess material from the edges of steel coils, thereby enhancing their overall appearance and ensuring uniform width throughout the coil. 5. Coating Machines: These machines are utilized to apply diverse coatings or finishes to the surface of steel coils, such as paint, galvanized coatings, or protective films. They often incorporate drying or curing systems to guarantee proper adhesion and durability of the applied coatings. 6. Packaging Machines: Packaging machines are employed to wrap or package steel coils for transportation or storage. They can envelop the coils in protective materials, such as plastic or paper, and secure them using strapping or other fastening methods. 7. Inspection Machines: These machines are used to scrutinize the quality and integrity of steel coils. They have the capability to detect defects, such as cracks, scratches, or surface irregularities, and provide feedback for the purpose of quality control. These examples merely scratch the surface of the diverse array of steel coil finishing machines available. Each machine serves a specific role in the steel coil finishing process, guaranteeing that the final product meets the desired specifications and quality standards.
- Q: Why can hot rolled coils be placed outside?
- Because hot-rolled steel coils are generally used as raw material for semi-finished products, they have to be further used for pickling and cold rolling to make more use. The rust and dust can be removed after pickling
- Q: Is steel easier to weld?Which is more brittle/less flexible?
- You should not attempt to do any traditional welding of steel to aluminum as they can form a hard and brittle inter metallic compound known as iron aluminide. You would have to employ a process that did not melt either species. Cladding could be an option but you are kind of limited to flat products that are sandwiched together. There is also explosive which does almost the same thing as cladding. Friction stir welding might be possible but I cant vouch for that. The temperature does get pretty hot, so I am not sure what would happen. But any of these suggestions would take specialized equipment not available to the average user. For weight, Al is 2.7 g/cc and Iron is about 7.8 so it is about 3 times heavier for the same volume. How strong either of them are greatly depends on specific alloys and heat treatment. I think some of the strongest aluminum alloys have a yield strength of about 50,000 psi which would relate to a relatively weak steel. For steel, there are alloys that can have yield strengths in the hundreds of thousands psi.
- Q: Im in the process of replacing the gutters/down spouts on my house. The top of the house is four sided. The bottom level has a porch area with 3 sides, two smaller roofs in the back, and one small roof on the side with all stainless steel gutters. A two story house. Not sure of the demensions. They were made at a Steel Mill where the previous owner, worked.This guy wants to buy the stainless gutters but I need to know the market value of this steel and offer him a price. Can someone tell me what I can sell it for? Does it go by the pound? Foot? Can you give me an idea please? Theres a lot of it! I have no clue what to do! Thanks!
- i know it goes buy the pound but i do not know how mutch a pound.waite for some more answers someone must know.or call your local junk yard and ask them.
- Q: I heard about a new bike the specialized allez steel. Has anyone heard anything about it. it will have all brand new components like shimano 2300 parts and everything. it looks nice.
- Steel? I doubt it's made out of steel, more labor and a heavier frame. Most likely aluminum. Shimano 2300 you say? The Shimano 2300 is the lowest of the low of Shimano road components. Most likely not too reliable and heavy. www.cyclestore .uk/productDetai... I think this is what you might be looking for.
- Q: What are the common coil lengths available for steel coils?
- The steel coil lengths offered in the industry and specific requirements are subject to variation. Nonetheless, several standard coil lengths are extensively employed in different applications. These encompass coil lengths of 100 feet (30.48 meters), 200 feet (60.96 meters), 300 feet (91.44 meters), and 500 feet (152.4 meters). These lengths find extensive use in construction, manufacturing, and automotive sectors, where steel coils serve diverse purposes. It is worth mentioning that coil lengths can also be tailored to meet specific project requirements or customer preferences.
- Q: How are steel coils priced?
- Steel coils are priced based on various factors such as the current market demand and supply, raw material costs, production and operational expenses, transportation costs, and other market dynamics. Additionally, factors like quality, specifications, and any additional processing or customization required can also influence the pricing of steel coils.
- Q: Are Steel Building Kits really helpful while erecting a steel building?
- I put up a 30'x40' Mueller Steel Building from a bolt together kit 6 yrs ago. Fully insulated, 2 10'x10' roll up doors, 1 walk thru door, 3 windows, 2' overhang all around, and gutters. The building price minus the slab was about $9500. The only special equipment was a neighbor's large Farmall with a hay spike on the FEL that we used to lift the trusses in place. Then it was mainly cordless drills to put in LOTS of self tapping screws, circular saw with metal cutting blade, tall ladders, etc. Had help putting up the trusses and putting up the roof panels. Everything else I did by myself. Took about 6 wks, but that was only working weekends and maybe 3 evenings a week since that land is 30 miles from my house. Would have gone a lot faster with at least one helper.
- Q: I know copper pots are supposed to be really good for cooking with, and I have been looking around online. One thing I don't want to do, however, is send them in to be re-lined with tin. So I was wondering if stainless steel lined copper pots work as well as the traditional tin lined ones, or if those make the copper just for looks.
- Stainless steel is durable and does not disolve and make things taste funny. Stainless steel is not a good conductor of heat, so it has hot and cold spots. Copper is very good conductor. They noe bond copper to stainless steel to get the best features of each. Some pots just have a very thin copper plating to fool you. A good pot will be heavier, It is really hard to tell from looking.if it is plating or a bonded layer of copper. the thicker the better
- Q: How are steel coils used in the production of automotive components?
- Steel coils are used in the production of automotive components as they are a primary raw material for manufacturing various parts like chassis, body panels, suspension systems, and engine components. These coils are processed and shaped using various techniques such as cutting, bending, stamping, and welding to create the required components, ensuring strength, durability, and precision in the final product.
