5.FAQ of Pre-Painted Galvanized/Aluzinc Steel Roof

What’s the brand of the paint?

We use the best brand of all of the word—AKZO.

What’s the wet and heat resistance of the roof?

More than 1000 hours.

Q: How can I tell the wear resistance, strength, ect from the name of the steel?how could I tell the difference between 420 and 440 steel. what does the HC in 420 HC steel mean? what do the numbers and letters in s30v steel mean?: So what does all that mean in the real world of knives. 420 has very low carbon by blade standards, as such it is just junk steel. There are three grades of 440, A, B and C. The amount of carbon in A is about half of what C has. (carbon is what makes steel get hard). Iron is very much like a sponge in that it can absorb and hold different alloys. These alloys give the iron different attributes, and they can magnify each other. Like a sponge iron can only hold so much, for Chromium it is around 13%. At that point the steel becomes stainless. The drawback is a loss of strength. As a bladesmith my knives are generally 59 to 60 rch, 420 and 440 at its hardest is 59 but at that it is brittle so most makers draw it down to around 57. In my test a knife made of 420 couldn't make 5 slicing cuts through rope (most couldn't make one). 440 averaged between 5 and 10. Compared to the lowest grade of carbon steel I use (5160) which average between 25 to 30 on the same rope. I have tested many stainless blades and the rule always the same, the more chromium past 13% the weaker the blade and the less edge holding ability.

Q: Can steel coils be coated with decorative designs?: Yes, steel coils can be coated with decorative designs. This is commonly achieved through various coating techniques like painting, powder coating, or laminating, which can add aesthetic appeal to the steel coils while enhancing their overall appearance and functionality.

Q: so I am trying to drill holes in stainless steel shelving to hang something but my drill wont make any more than a small dent in the steel. I bought a bit for hard metals but it didn't do any better. I have an admittedly small drill (9.6v). is that the problem? do I just need a more powerful drill? any serious advice is appreciated. thanks: Just put drops of water at the spot of drilling to keep your drill bit cool. The reason your drill bit gets dull is because it gets hot and melts.You may need to re sharpen your drill bit or purchase a new one.

Q: How do steel coils contribute to the transportation industry?: Steel coils contribute to the transportation industry by being used to manufacture various components and structures for vehicles, such as the body frames, chassis, and suspension systems. These coils are also used in the production of shipping containers, railcars, and cargo ships, ensuring the safe and efficient transportation of goods across different modes of transport.

Q: I want to buy a machete made of 1055 carbon steel, and want to know if this steel is durable for repeated use, or even combat use.: This Site Might Help You. RE: What is the level of dependability of 1055 carbon steel? I want to buy a machete made of 1055 carbon steel, and want to know if this steel is durable for repeated use, or even combat use.

Q: How are steel coils inspected for formability?: Steel coils are typically inspected for formability through a combination of visual inspection, mechanical testing, and laboratory analysis. Visual inspection involves examining the surface of the coil for any visible defects such as scratches, dents, or deformities that could affect its formability. This is usually done by trained personnel who carefully inspect the entire surface of the coil. Mechanical testing is also commonly employed to assess the formability of steel coils. This can include conducting physical tests such as tensile testing, where a sample is subjected to controlled forces to measure its strength and elongation properties. This helps determine if the steel has the necessary ductility and strength to be formed into the desired shape without cracking or breaking. Additionally, laboratory analysis is often conducted to assess the chemical composition and microstructure of the steel. This involves taking small samples from the steel coil and analyzing them using techniques such as spectroscopy and microscopy. These analyses can provide valuable insights into the steel's composition, grain structure, and other characteristics that can impact its formability. Overall, a combination of visual inspection, mechanical testing, and laboratory analysis is used to ensure that steel coils meet the required formability standards. This comprehensive approach helps identify any potential issues or defects that could affect the performance and reliability of the steel when it is formed into its intended shape.

Q: What is the difference between hot rolled and cold rolled steel coils?: The main difference between hot rolled and cold rolled steel coils lies in the manufacturing process. Hot rolled steel coils are produced by heating the steel to high temperatures and then rolling it while it is still hot. This process results in a rougher surface and less precise dimensions, but it makes the steel more malleable and easier to shape. On the other hand, cold rolled steel coils are manufactured by cooling the hot rolled coils and passing them through a series of rollers at room temperature. This process produces a smoother surface and tighter tolerances, making it suitable for applications that require precise dimensions and a higher quality finish.

Q: How are steel coils used in the manufacturing of automotive exhaust systems?: Steel coils are used in the manufacturing of automotive exhaust systems as they provide the necessary strength and durability required for this critical component. These coils are typically shaped and formed into various parts such as pipes, mufflers, and catalytic converters, which are then welded together to create the exhaust system. The steel coils also undergo additional processes like coating or galvanizing to enhance corrosion resistance, ensuring the longevity of the exhaust system.

Q: I just got a set of all-clad Stainless steel frying pans, they are very nice yet they didn't come w/ instructions to care for them. I have never cooked w/ stainless steel cookware so I really don't know much about them. I was told they should have a lifetime warranty on them, but I don't want to reck them. I would appreciate any information I can get on stainless steel cookware. Thanks.: I have stainless steel as well. i clean them like I would with any pan. however once and a while when the bottems get kind of blackened due to spillage or flames I take one of those magic eraser things to clean them up. once every 2-3 months I polish the outsides with a nice stainless steel cleaner.

Q: How are steel coils used in the production of metal signage?: Steel coils are used in the production of metal signage by being cut and shaped into the desired size and shape for the signs. The coils provide a sturdy and durable base material for the signs, ensuring their longevity and ability to withstand various weather conditions.
