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.

- Q:They are showing on tv a special on how the new World Trade Center, building 1, is being built. Focusing on the steel and the guys fitting everything together.Where do builders go to buy all that steel framing? We do not build really tall buildings where I live so most of the steel is cut and welded on the job site. At World Trade Center 1, they seem to get the steel on trucks; already cut and welded.
- The steel is all custom fabricated in what are called structural steel fabrication shops. Each Building is designed by architects then the frame is designed by engineers to support whatever load is being applied to the building. After the engineering is done it goes out for a bid package where a fab shop estimates how much to charge for the fabrication of the steel and the erection of the steel. Once a company wins the bid, it then has to design how the steel will connect with one another and have it approved by an engineering firm to assure the connections are strong enough. Once all of that happens the fab shop orders raw steel beams and angle iron and steel plate at stock lengths. Beams are then cut into the right length and holes drilled in the proper places. The beam is then marked with a number that tells the erectors where it goes. The steel is then shipped out in batches to the construction site where it is unloaded and shook out into an organized place to grab them with a crane. They are then put together like a toy model, there are instructions that say what beam goes where and what size bolt to use. The welding you see being done is on really critical moments that need extra strength. That is about how it goes in a nutshell. It is a bit more complicated than that but it gives you an idea.
- Q:What is the typical lead time for ordering steel coils?
- The typical lead time for ordering steel coils can vary depending on factors such as the supplier, quantity required, and current market conditions. However, it is common to expect lead times ranging from a few weeks to a couple of months.
- Q:How many millimeters is a number 3 steel crochet hook?
- A okorder /. . If your hooks are marked by letters and milimeters, they are likely intended for working with YARN, not crochet thread. The steel hooks are smaller and are used with thread rather than with yarn. In addition, if you're working with a vintage pattern, a hook may be called for that you cannot purchase today. Here is a web site that explains many of the puzzling questions about hooks
- Q:What are the typical lead times for ordering steel coils?
- Lead times for ordering steel coils can vary based on factors such as coil type, size, supplier capacity, and market conditions. On average, lead times range from a few weeks to several months. When it comes to standard-sized steel coils readily available in the market, lead times are generally shorter. This is because suppliers keep stock of these commonly used sizes to meet immediate customer demands. However, transportation and logistics can still impact lead times. For custom-made or non-standard steel coils, lead times tend to be longer due to additional processes like cutting, shaping, or coating. Production time can range from a few months to six months or more, depending on the complexity of specifications and supplier capabilities. External factors like market demand and raw material availability can also affect lead times. During high demand or supply chain disruptions, suppliers may need to adjust production schedules, leading to extended lead times. To determine accurate lead times, it is recommended to contact specific suppliers or manufacturers. They can provide the most up-to-date information based on your requirements and current market conditions.
- Q:Can steel coils be used in the production of packaging materials?
- Yes, steel coils can be used in the production of packaging materials. Steel coils are often used as the core material for packaging materials such as metal strapping and steel banding. These coils are strong, durable, and provide excellent tensile strength, making them ideal for securing and protecting various products during transportation and storage. Additionally, steel coils can be easily shaped and formed into different packaging components, ensuring a secure and reliable packaging solution for a wide range of industries.
- Q:What are the different types of welding methods used for steel coils?
- There are several different types of welding methods used for steel coils, including gas metal arc welding (GMAW), flux-cored arc welding (FCAW), shielded metal arc welding (SMAW), and submerged arc welding (SAW). Each method has its own advantages and is used based on the specific requirements of the project.
- Q:looking to buy a sashimi knife. what is the difference between white steel (1and2) and blue steel (1and2) in terms on characteristics. what gets sharper? what holds edge longer? basically any info on the pros and cons of each steel would be SO GREATLY APPRECIATED! thanks in advance to all who answer. i'm leaning towards white-2 steel for my first sashimi knife, started training on the sushi bar and need a new tool!
- Steel Sushi
- Q:What are the different types of steel coil handling systems?
- There are several different types of steel coil handling systems, including coil upenders, coil cradles, coil transfer cars, coil tilters, and coil grabbers.
- Q:I've heard on some 1911 forums that the slides of Armscor guns are now extruded. What is extruded steel? How is it made? Are they strong (4140carbon steel was used in the process).
- Extruded steel is only the steel being run through a die when it is heated, it usually reduces the size of the grain of the steel itself, enhancing toughness. Realistically though, in a handgun, it doesn't matter if the frame is cast or forged, both types will hold up to any amount of abuse, unless you use it as a sledgehammer, and are splitting stones with it, then the forged frame would win. 4140 is more than adequate for a slide/frame. Hell, even mild steel would be adequate as long as you don't mind some dings and scratches, and again, don't use it as a sledgehammer...
- Q:How much should someone sell a 6 ft stainless steel counter? How about one with a sink?
- Sheet stainless steel is about $2.00 to $2.75 per lb. in the US right now for a 2B stainless steel without any special finish. The cost of a sink or counter is going to vary widely. The labor to fabricate it is going to be a lot higher than the material cost so the price per pound is not going to tell you much. In California a custom 6' counter would be somewhere between $1,200 and $3,000. A standard size single compartment sink would be about half of that.
