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.

- Q:Search the internet for 'Frost Clipper Knife'. This knife comes in either stainless or carbon steel. I have a friend who has one (stainless steel) and he is very impressed with it, but I have heard that Carbon Steel blades are better? Discuss...
- If your talking about a folding pocket knife, I think that it's basically six one way and a half dozen the other. I actually do prefer stainless for my pocket knives. I don't want to oil a knife to the degree I feel carbon requires, only to then stick it my pocket to attract dirt to the knife and oil to my pants. I'm the exact opposite on sheath knives though. I like 1095 carbon steel, plain edge sheath knives. I'll thrash on them HARD, and I rarely have major edge problems. Of course, I require them to be coated with some kind of powder coat or the like, because they can rust, but I do try and keep them clean and dry when in the sheath, so they won't pit the uncoated edge. My reasons for this sheath knife preference is multi-fold. First, these knives are simply affordable. I don't spend $80 dollars on a outdoors sheath knife. I use the tool too hard to want to spend more. I don't like the more traditional stainless steels such as AUS-8, 420HC, and 440C (not to mention the HORRENDOUS 440A) because I feel that the all else being equal, a stainless blade will bend before a carbon blade will break. I also think that carbon holds an edge at least as well, if not better, than traditional stainless, and it's much easier to hone. I don't know much about these new laminates, other than the very hard, but not so tough. They seem to be POSSIBLY too brittle for my use. That, combined with the fact that they cost a FORTUNE, means that I just won't be considering them.

- Q:How are steel coils used in the production of HVAC ducts?
- Steel coils are an essential component in the production of HVAC ducts. These coils are typically made of galvanized steel, which provides strength, durability, and resistance to corrosion. In the manufacturing process, steel coils are first unwound and flattened to create flat sheets. These sheets are then cut into specific sizes and shapes according to the design and dimensions of the HVAC ducts. The steel coils are often processed through various machines, such as shearing machines, slitting machines, and roll forming machines, to achieve the desired shapes and sizes for the ducts. Once the steel coils are transformed into the appropriate shapes, they are then further processed to add additional features to the ducts. For instance, the coils may undergo bending, folding, or welding processes to create bends, angles, or connections in the ductwork. These processes allow for the customization of the ducts to fit the specific requirements of the HVAC system and the building structure. Furthermore, steel coils play a crucial role in ensuring the strength and integrity of HVAC ducts. The galvanized steel used in the coils provides a protective layer that prevents rust and corrosion, making the ducts more durable and long-lasting. This is especially important as HVAC ducts are often exposed to various environmental factors, such as moisture, temperature changes, and airborne contaminants. Overall, steel coils are a fundamental component in the production of HVAC ducts. They provide the necessary strength, durability, and resistance to corrosion, while also allowing for customization and flexibility in the manufacturing process.

- Q:Hello,is it possible to divide an alloy in its own elements? I am particularly interested in Stainless Steel, which is made of Nickel, Chrome and Iron. Do you have an idea of where can I find some more information (blogs, reviews, sites or books)?Thanks for your help
- Yes it is possible to recover individual elements from an alloy such as stainless steel, but not easy. Look up etching of stainless steel on google. This same etching solution will completely dissolve stainless steel. These solutions are strong acids such as H2SO4 and HNO3 so safety goggles and good ventilation are absolutely required. Once the metal has been dissolved, then you would need to use a qualitative analysis scheme to precipitate out the different metals one at a time as compounds, then do additional reactions to recover the metallic elements.
