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: In construction, what types of stress require steel to be placed in footings?
- Steel is always added to concrete to handle local 'tension' stresses. (Sometimes to provide extra compression in 'pre-stressed' applications, but the steel is still in tension.) Steel would be added to the lower section of footings to stiffen them to 'bridge' local 'soft spots' in the substrate.
- Q: I'm currently in an Estimating and Bidding class. I have to estimate two divisions for a multi-million dollar project. The project that I chose is around 6 million dollars and involves constructing a new gas/lighting building. I chose to estimate steel, and my question is, around how much out of the 6 million goes toward just the steel estimate? If it helps, this building is has two floors and is roughly about 100x70 feet. The building not wood construction, but rather steel and brick. How much of that 6 million would go into the steel? I'm not looking for anything exact, just roughly.
- That is a little tough to answer given the details. I will try to answer it as best I can. You can send me a message if you need further help and I can get some more details from you. If it is a 6 million dollar project, that is about $428/sf - (6 million divided by 14,000 sf). $428 is a little bit higher end then say, just a Walmart which is a block and steel box. Assuming you have a concrete slab on the first floor, metal deck on the second floor, with steel beams and open web joists framing, steel columns and steel roof framing with a metal deck roof.... you could be approx 10-15% of the total 6 million. Now, this would include the structural steel, not light gauge steel framing for walls. It sounds like you are looking for structural steel, not metal stud framing. Hopefully this helps, I can check back to this thread later to see if you've had to add any more details.
- Q: What are the safety precautions to be taken while handling steel coils?
- Some safety precautions to be taken while handling steel coils include wearing appropriate personal protective equipment (PPE) such as gloves, safety glasses, and steel-toed boots to protect against potential injuries. It is important to use proper lifting techniques and equipment, such as forklifts or cranes, to avoid strains or falls. Coils should be stored on stable surfaces and secured to prevent them from rolling or falling. Additionally, workers should be trained on proper handling procedures and be aware of the potential hazards associated with sharp edges, heavy weight, and unstable loads.
- Q: Steel used to be made in the #92;Bessemer Converter, write about how steel making processes today produce better quality steel????
- Steel making today is a faster process as use Blast furnace which Coke Limestone Iron ore are fed into the top of the furnace. after these are fed in a exothermic happens and converts these ores into Iron. Iron is not strong enough to be used in thing this is formally known as pig iron. To convert Iron ore into steel it has to go to a process called the BOS Basic Oxygen Steel-making were oxygen is blown onto the iron ore for about 30 to 45 min and this then turns it into steel as all the impurities are taken out and this floats on top and known as slag and used for things such as road building. Once you have steel this is then pored into ladles and taken to the continuous caster and rolled into slabs, billets and bars and then cut off and rolled into a finished products and then taken to compniaes to be made into thins you see made out off metal such as skyscrapers. Hope this helps :o)
- Q: So finally got around to watching man of steelnow i heard a few times that batman was in iti didn't se him.in the film is it something subtle I've just missed or is he not in it?when i googled it got loads of results for them being together in the new film but nothing about man of steel 2013
- No, however he will make an appearance in Batman V Superman: Dawn of Justice out next year.
- Q: Are you people aware of commercial steel warehouses, If yes then can you please explain their advantages and benefits?
- Compared to what?
- Q: Iron melts faster when there will be low carbon in Iron.During steel making the molten Iron gets purified and alloying being done through the process. How the carbon is being controlled at Iron melting stage and what it is called?
- Steel is usually made in a two-step process. As you may know, carbon, in the form of coke, is added to the iron ore during the initial smelting process. This is the first step. The conversion of iron ore into raw iron is accomplished with a blast furnace. Carbon dissolves with the iron during the smelting process. The amount of carbon in the iron is generally not controlled at this point as this would be too difficult, the excess carbon is removed in the next step. The result is pig iron which is crude iron that has a very high carbon content, and a large amount of impurities. Pig iron is almost as brittle as glass, and it is useless in this form. In most modern steelmaking operations, molten pig iron is tapped from the blast furnace three or four times per day- it is not allowed to cool. The liquid pig iron is carried in ladles directly to a Basic Oxygen Furnace which converts the pig iron into steel. The basic oxygen converter uses a stream of pure oxygen to burn off the excess carbon. Impurities are also burned off, particularly phosphorus, silicon, and sulfur (which damage the steel's properties.) These elements all have a much higher affinity for oxygen than iron does, so the iron itself remains unchanged. Once the carbon content and the impurities are reduced to the desired level. The oxygen is shut off, and the iron has now become steel. At this point other alloying elements may be added, such as chromium, manganese, or molybdenum. These elements improve the steel's properties, but also add to it's price. If necessary, more carbon can be added as well if the carbon content has accidentally dropped too low. Finally, molten steel from the basic oxygen furnace is poured off. It can be cast into ingots, billets, or thin slabs.
- Q: What are the different types of steel coil finishes for aesthetics?
- There are multiple varieties of steel coil finishes utilized for aesthetic purposes, each offering a distinct appearance and texture to the steel surface. Some of the most prevalent finishes include: 1. Matte finish: This finish boasts a low-gloss appearance, providing a smooth and non-reflective surface. It imparts a clean and contemporary look to the steel coil, making it suitable for a range of architectural and interior design applications. 2. Brushed finish: Also referred to as a satin finish, this type of finish is achieved by brushing the steel surface with a fine abrasive material. It produces a subtle and directional grain pattern, resulting in a textured appearance. Brushed finishes are commonly employed in kitchen appliances, decorative elements, and furniture. 3. Mirror finish: As the name suggests, this finish creates an intensely reflective surface similar to a mirror. It is accomplished through the process of polishing the steel surface to a high shine using abrasive materials. Mirror finishes find common usage in architectural applications like decorative panels, elevator doors, and signage. 4. Patterned finish: This finish involves embossing or etching a pattern onto the steel surface, ranging from simple geometric designs to intricate textures. It offers a unique and visually captivating appearance. Patterned finishes are widely used in interior design, automotive trims, and decorative panels. 5. Textured finish: Textured finishes are created by applying a texture to the steel surface, such as a stucco or diamond pattern. This enhances depth and visual interest, making it suitable for various applications including wall cladding, roofing, and garage doors. 6. Colored finish: Apart from different surface textures, steel coils can also be finished with a variety of colors. This is achieved by applying a coating or paint system, which enhances both the aesthetic appeal and protection against corrosion. Colored finishes are commonly employed in architectural applications such as building facades, window frames, and decorative elements. Ultimately, the choice of steel coil finish depends on the desired aesthetic outcome, as well as the specific requirements and intended application of the steel product.
- Q: How are steel coils used in the production of storage tanks and silos?
- Due to their strength and durability, steel coils are essential in the production of storage tanks and silos. Typically made from high-quality steel, these coils undergo various manufacturing techniques to achieve the desired thickness and shape. In the production process, the steel coils are initially uncoiled and then cut into specific sizes and lengths to meet the requirements of the storage tank or silo design. Bending and rolling machines are then used to shape the coils into cylindrical sections, forming the main body of the tank or silo. After achieving the desired shape, the coils are welded together to create a continuous and secure seam. This welding process ensures leak-proof tanks and silos that can withstand the pressure exerted by the stored materials. Furthermore, steel coils play a crucial role in reinforcing the structure of storage tanks and silos. They are frequently utilized to construct the roofs, bottoms, and other structural components of these storage units. The strength and resilience of steel make it ideal for supporting the weight of the stored materials and resisting external forces. Additionally, steel coils can be coated or treated with protective materials to enhance their resistance to corrosion and extend their lifespan. This is particularly important for storage tanks and silos that store corrosive substances or are exposed to harsh environmental conditions. In conclusion, steel coils are a fundamental element in the production of storage tanks and silos, providing the necessary strength, durability, and structural integrity required for these storage units.
- Q: What are the different methods of edge trimming for steel coils?
- There are several methods of edge trimming for steel coils, depending on the specific requirements and application. Some of the common methods include: 1. Slitting: This is one of the most common methods used to trim the edges of steel coils. It involves passing the coil through a set of circular knives that cut the edges into narrower strips. Slitting can be done in-line during the manufacturing process or as a separate operation. 2. Shearing: Shearing is another popular method used for edge trimming. It involves using a set of blades to cut the edges of the coil in a straight line. Shearing is often used when precise and clean cuts are required, and it can be done manually or with the help of automated machinery. 3. Laser cutting: Laser cutting is a more advanced method that uses a high-powered laser to trim the edges of steel coils. This method provides precise and smooth cuts, and it is often used when high accuracy and quality are essential. Laser cutting can be incorporated into the production line or performed as a standalone process. 4. Grinding: Grinding is a method that involves using abrasive wheels or belts to remove material from the edges of steel coils. It is commonly used to remove burrs, rough edges, or surface imperfections. Grinding can be done manually or with the help of automated machines, depending on the scale and complexity of the trimming process. 5. Waterjet cutting: Waterjet cutting is a method that utilizes a high-pressure jet of water mixed with abrasive particles to trim the edges of steel coils. This method is known for its versatility and ability to cut through a wide range of materials and thicknesses. Waterjet cutting is typically used when complex shapes or intricate designs need to be achieved. Overall, the choice of edge trimming method for steel coils depends on factors such as the desired accuracy, speed, complexity of the edges, and the specific requirements of the application. Different methods offer varying levels of precision, efficiency, and cost-effectiveness, allowing manufacturers to select the most suitable technique for their specific needs.
