Q:How do the sandpaper grits compare with different coarse levels of steel wool? For example, I'm finishing a homemade entertainment center, and using a tinted polyurethane, and it says to use 000 grade steel wool, but mine is #3, could I use some sanpaper instead, and what grit?: 150 grit is standard for final sanding for poly. You could use 220 if you finish with something thinner like lacquer of if that's all you have. Even finer would work but not do much sanding.

Q:What are the environmental considerations of using steel coils?: There are several environmental considerations associated with using steel coils. Firstly, the production of steel coils requires a significant amount of energy and raw materials, which can contribute to greenhouse gas emissions and environmental degradation. Additionally, the extraction and processing of iron ore for steel production can have negative impacts on land, water, and air quality. Moreover, the transportation of steel coils, especially over long distances, can result in emissions from vehicles and contribute to pollution. Lastly, the disposal of steel coils at the end of their lifecycle poses challenges as they can be difficult to recycle and may end up in landfills, further contributing to waste accumulation. Overall, the environmental implications of using steel coils highlight the need for sustainable practices in their production, transportation, and disposal.

Q:How are steel coils used in the manufacturing of household goods?: Steel coils are commonly used in the manufacturing of household goods as they are shaped and processed into various components such as frames, springs, and supports. These coils provide strength, durability, and stability to items like furniture, appliances, and automotive parts, ensuring their longevity and functionality.

Q:Maybe it is obvious. But i have thought alot about it.I thought steel at a cool temperature was unbreakable. I am not one for science or physics or engineering (i am a political science major). But i don't understand why the planes that struck the world trade center on 9-11 didn't just dent the side and fall,How did the place break the steel? Was it the velocity? Is steel easily broken?I realized that i wasn't taught how the planes broke the steel, and that no one ever asked. I searched the web and i couldn't find the answer or even anyone who had asked the question before.(i don't care about conspiracy theories, i just want scientific facts): steel is not unbreakable. the world trade centers had a steel infrstructure, but were mostly glass and materials with many other flaws. steel is not the top of the rocwell scale(materials rated by thier hardness) when the planes impacted the outside of the buildings, you have to take into account that the planes skins and infrastructure where made of aluminum(too keep weight down) so once the outer skin of the planes was breached, you have to account for the heat created by burning fuel, friction, and the momentum of a vehicle that weighs tons hitting an immovible object. just keep in mind that if you propel a piece of straw at an proper speed, you can have it impale a full grown palm tree

Q:Yes, I understand it can weaken steel greatly. But can it MELT steel? (key word: melt): Jet fuel is kerosene in 6 grades and highly filtered. can it melt or weaken steel? No, it preserves it.

Q:How are steel coils used in the manufacturing of engine mounts?: Steel coils are used in the manufacturing of engine mounts as they provide strength, durability, and flexibility. These coils are typically used as the main component of the mount, providing the necessary support and stability for the engine. The steel coils are designed to absorb and dampen vibrations, ensuring smooth operation and minimizing the transfer of engine vibrations to the vehicle.

Q:What is the role of steel coils in the production of pipes and tubes?: Steel coils are an essential component in the production of pipes and tubes as they serve as the raw material for manufacturing. The coils are unwound and then shaped into the desired pipe or tube form through various processes such as rolling, bending, and welding. The steel coils provide the necessary strength, durability, and structural integrity required for the pipes and tubes to withstand high pressures, extreme temperatures, and other demanding conditions.

Q:What are the common coil diameter and weight combinations available for steel coils?: The common coil diameter and weight combinations available for steel coils vary depending on the specific requirements of the industry or application. However, some commonly available coil diameter ranges include 24 inches to 72 inches, while weight combinations can range from 3,000 pounds to 50,000 pounds or more. These dimensions can be further customized based on the needs of the customer and the capabilities of the steel manufacturer.
