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:for a roof spanning 14.4m x 8.4m on a residential house, is it better to use timber trusses or steel trusses? the priorities are; ease of construction, price, insulation (want to keep heat out, i am in a tropical country), durability, flexibility, minimal load on foundations.please help. thank you :-)
- How about another option - Steel Re-inforced Concrete Beams. Beam planks would span 8.4 metres but to keep the cost down have an I beam support at 4.2m. Concrete is great. It goes on quick, is sound proof, (very nice when it rains or for road traffic), can have gravel laid on top to act as a heat sink for winter sun and can be covered with normal roof steel if you want to hide it. Its also rust and borer free. While you would need good supports for the front and back, although with an I beam you can have a floating front, it is not much more than what is required for a wooden top. Design it right and your roof could be a future floor for the next addition.
- Q:Does steel have a valence number and if so, what is it?
- Steel is a mixture, so it doesn't have any valence number. On the other hand, all of the components of the steel mixture are in their elemental forms, so all the various valences are zero.

- Q:What are the common challenges in steel coil manufacturing?
- Steel coil manufacturing often encounters several challenges that manufacturers must address. One key issue involves the need to consistently uphold quality standards throughout the manufacturing process. Meeting precise specifications is crucial for steel coils, as any deviations can result in product defects or rejections. Therefore, constant monitoring and implementing quality control measures at each production stage are necessary. Another obstacle involves optimizing production efficiency and minimizing downtime. The production of steel coils encompasses various intricate processes, including cutting, forming, welding, and finishing. Delays or problems in any of these stages can create production bottlenecks, negatively impacting overall efficiency and productivity. Additionally, challenges arise in the handling and storage of steel coils. Due to their weight, steel coils can be challenging to manipulate, necessitating specialized equipment and proper worker training. Moreover, maintaining appropriate storage conditions is vital to prevent damage from factors like moisture, corrosion, or other environmental elements. Maintaining a safe working environment poses another challenge in steel coil manufacturing. Improper operation or maintenance of the equipment and machinery used in the process can lead to hazardous situations. Therefore, ensuring worker safety and implementing suitable safety protocols are crucial to prevent accidents and injuries. Lastly, fluctuating raw material costs and market demands present challenges for steel coil manufacturers. The profitability of the manufacturing process is significantly influenced by the costs of raw materials like iron ore and scrap metal. Furthermore, market demands for specific steel coil types can fluctuate, necessitating manufacturers to adapt and adjust their production accordingly. To overcome these challenges, careful planning, continuous improvement, and effective resource and process management are essential in steel coil manufacturing.
- Q:How are steel coils used in the production of steel cables?
- Steel coils are used in the production of steel cables as they serve as the raw material for cable manufacturing. The steel coils are unwound and then processed through a series of steps, such as drawing, stranding, and coating, to transform them into steel cables of various sizes and strengths. These cables are widely used in industries like construction, transportation, and telecommunications for purposes such as supporting structures, lifting heavy objects, and transmitting electrical signals.
- Q:Hi,Well, I live near almost across the street from a forest, and my neighborhood is full of raccoons!!! Recently, I just purchased a bunny and have kept it at my cousin's house for the time being. He has a steel cage, and is about 6 months old. I am considering bringing him home and leaving him in the back yard with his steel cage. I am just afraid that raccoons can bite through the steel and get to him. So the question is... Is is possible for raccoons to bite through steel? Btw,Please don't answer hate comments about me being a bad rabbit owner. I simply want to know if raccoons can bite through steel. If it doesn't work out, the rabbit will stay at my cousins house until further notice. But please, I did not waste 5 points for unneeded answers. Thanksss!
- Well the raccoons can't bite through steel unless it is very thin steel, like aluminum foil thickness. But they have long arms and can reach into the cage so that would be my worry. They are also very clever so I don't know if it is safe for the bunny. That would depend upon the size of the cage and how hungry the raccoons are. The raccoons might be tempted to try to steal the bunny's food so that is a concern. Check with a pet shop owner or forester or someone like that who has knowledge about raccoons in the area.
- Q:And by how much? I'm pretty sure that sterling silver is stronger, but I'm wondering if I could still use a metal stamp to stamp into something that's stainless steel - if it would be soft enough?
- No way steel is by far stronger. Tensile strength of Sterling silver 207 MPa Tensile strength of Stainless Steel 515 MPa
- Q:The hard industrial steels. If there's a bunch, what's a rough average? Also, what is is measured in?
- The general purpose default steel for hard tooling applications is A2 It's cheap, readily available and comes in many different shapes and sizes. It's easy to machine soft. It's easy to harden, you can do it yourself. It is very dimensionally stable during hardening. All the steels mentioned above are specialty steels - expensive to buy, hard to work with, expensive to heat treat and dimensionally unstable during heat treat.
- Q:How are steel coils used in the manufacturing of springs?
- Steel coils are used in the manufacturing of springs by being formed into a helical shape, allowing them to store and release energy when subjected to force or pressure.
- Q:This problem has puzzled me for a long time i always think about why stranded people on islands cant make a proper civilization and i always think it comes down to the ability to work metal. But its not like they could make a steel smelter/furnace out of sand...they would need an older one to use to make the new one...where the hell did the first one come from then????
- it is a problem to work metals thats why the first furnaces were for metals with a low melting point eg copper. To built a furnace for iron you need a very high temperature and for steel additional chemical treatment probably not available on an island. To smelt iron should be possible though as a clay furnace with the right coal is hot enough to produce raw iron.
