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

- Q:I need help! Please help, I'm in Chemistry, and me and my friend Lucy are making a presentation on steel and iron, so how is steel manufactured? Thank you. :D
- The steel consists of ( Iron ) and another matter... but the popular one is iron+carbon / iron+silver - When iron is smelted from its ore by commercial processes, it contains more carbon than is desirable. To become steel, it must be melted and reprocessed to reduce the carbon to the correct amount, at which point other elements can be added. This liquid is then continuously cast into long slabs or cast into ingots. Approximately 96% of steel is continuously cast, while only 4% is produced as cast steel ingots. The ingots are then heated in a soaking pit and hot rolled into slabs, blooms, or billets. Slabs are hot or cold rolled into sheet metal or plates. Billets are hot or cold rolled into bars, rods, and wire. Blooms are hot or cold rolled into structural steel, such as I-beams and rails. In modern foundries these processes often occur in one assembly line, with ore coming in and finished steel coming out. Sometimes after a steel's final rolling it is heat treated for strength, however this is relatively rare.
- Q:Can't find it- this is for a physics experiment for youngs modulus done with a steel wire.
- It is the Yield Strenght that you are looking for...that is another word for elastic limit. AND, for steel, it does depend on the variant of steel. Not all types of steel are identical, since steel isn't a pure substance. For Young's modulus (and other stiffness properties), just about all variants have the same values. However, for strength properties like Yield strength and ultimate strength and fatigue strength, it does depend on variant, and is precisely why different recipies exist in AISI standards.
- Q:Where can a find a steel scrubber. Its great to clean cooking vessels. Would be great if someone gives me an idea. I did not find it at CVS, but was in a hurry, will try again tomorrow.
- I posted this earlier to a similar question... Really burnt on gunk in the bottom like milk or blackened food can easily be cleaned out of stainless steel pots and pans by sprinkling baking soda in the bottom, covering with vinegar, let simmer with a little water for 5 min. Let cool, scrub out with a vinyl scrubby. or I use a lot of stainless steel for cooking and over the years have found a very inexpensive solution to cleaning them especially the ones with burnt food stuck at the bottom. I use Used fabric softner sheets (sheets that i have already used in the dryer for my clothes) and have them soak in water in the dirty pan overnight. Next morning i use the same sheet as scrubber to clean the pan and all the burnt food comes off easily leaving a new look to the pan. Try it this works.
- Q:What are the different steel coil surface treatments?
- There are several different steel coil surface treatments available, including hot-dip galvanizing, electro-galvanizing, chromate-free treatment, and organic coating. Each treatment provides different benefits and protection against corrosion and other environmental factors.
- Q:How do steel coils contribute to the automotive manufacturing sector?
- Steel coils are essential in the automotive manufacturing sector as they are used to produce various components such as body parts, frames, and suspension systems. The high strength and durability of steel coils make them ideal for ensuring the safety and structural integrity of vehicles. Additionally, steel coils are easily moldable, allowing manufacturers to create complex shapes and designs, contributing to the overall aesthetics and functionality of automobiles.
- Q:How are steel coils used in the manufacturing of engine mounts?
- Steel coils are used in the manufacturing of engine mounts to provide structural support and absorb vibrations generated by the engine. The coils are designed to provide tension and flexibility, allowing the engine to be securely mounted while minimizing the transmission of vibrations to the rest of the vehicle.
- Q:How are steel coils used in the appliance industry?
- Steel coils are used in the appliance industry for a variety of purposes such as manufacturing parts, components, and frames for appliances like refrigerators, washing machines, and ovens. The coils are processed and shaped into specific forms to provide strength, durability, and stability to the appliances.
- Q:They both sell the same thingIf prices are to high companies won't by the steelIf prices are to low then the steel company won't earn enoughWhy are some steel companies more successful than others
- Steel is a global commodity. There is some variety in product (flat rolled, tubing, etc), but basically the same product worldwide. Cost to the customer includes shipping of a very heavy product. Inputs are also heavy and costly to ship. Inputs: - Coal - Iron Ore. Some firms have the ability to recycle old steel, a competitive advantage. - Energy (very energy intensive industry) - Labor - Machinery. A new blast furnace is more efficient than 50 years old. So the most profitable steel firms have some of these characteristics: - Proximity to raw materials - Proximity to customers - Access to cheaper means of transportation; rail and sea - Newer machinery - Cheaper labor force - Reasonable cost for electricity and fuel for furnaces
- Q:I know that it is used for katanas and swords but what is it and is it good i am pretty sure that it is the process of the steel but can I have a little more information.
- Damascus or Wootz was a type of steel that appeared around 300BC It originated in India before spreading throughout Asia and the Middle East. It was considered a good steel, and for it's date of origin, exceptionally advanced for the level of technology in the ancient world. However the techniques to create the steel were lost forever after a decline in the swords manufacturing. The most popular theory is that the metal containing the required trace elements became less available over time due to unreliable trade routes. In the modern area, many scientists and metallurgists have studied the surviving blades, resulting in many discoveries such as evidence of carbon molecules fused in a crystalline structure. While the blades do provide some clues, it's only a small part of a much bigger picture as to the full process of the metal from raw to finished product. Now many have claimed to have recreated Damascus/Wootz steel, but none are recognised as being authentic. It has become a market ploy these days that draws people to purchasing the blades but all you are actually seeing is one of the many various forms of folded or patterned steel, which has varying degrees of quality, strength etc. We do know the steel was folded similar to the way the Japanese did in creation of old Katana, so often people will sell Damascus steel Katana that are nothing but folded steel swords like others. (Which is beautiful and traditional, but was a process designed to uniform impurities in the metal, something we no longer need to do with modern metals)
- Q:What are the dimensions of steel coils used in the agricultural structure industry?
- The dimensions of steel coils utilized in the agricultural structure sector may differ based on the particular application and requirements at hand. Nevertheless, standard dimensions for steel coils in this industry span from 0.5mm to 3mm in thickness and from 600mm to 1500mm in width. The length of the coils can also vary, but typically falls between 1000mm and 3000mm. These dimensions afford flexibility in constructing agricultural structures like barns, sheds, and storage facilities, all while ensuring ample strength and durability. It is worth noting that precise dimensions may vary depending on the manufacturer and the unique demands of the agricultural project.
