Description of BMP Z15 PPGI Rolled Steel Coil for Construction Roofing Constrution

Galvanized sheet or coil is defined as a carbon steel sheet coated with zinc on both sides. Continuous hot dipping, or electro-galvanizing are the two processes used to produce galvanized sheet and coil. Generally speaking, the hot dip process  consists of passing the steel through a bath of molten zinc. The electro galvanizing process consists  of  the  application  of zinc by electrolytic disposition.The result is a layer of zinc tightly adhering to the base metal through an iron-zinc bonding layer.

Q:Carbon Steel strength grading?
Depends on the sword design. Some swords are high carbon, some a low carbon, some are made from a billet of alternating high and low carbon ('Damascus' steels). It all depends on what characteristics you want for your sword. Softer steels won't hold an edge as well but they offer great flexibility so your sword won't shatter when they make impact with armor or shields. Harder steels hold better edges but they're prone to binding in wooden shields and then being broken as soon as a bending force is applied along the weak axis of the blade. Japanese Katanas have both hard and soft steels to allow the blade to bend yet still hold strong edges. If you're making the sword from raw materials on your own, look up some different recipes for crucible steel. It's probably the most fun and involved process.
Q:Pros and cons of stainless steel firearms?
The other posters here have already covered the pros of stainless steel firearms. I think they are just fine and actually require less maintenance. But, allow me to add one negative note about stainless. It may seem minor, but I have personally had an issue with it. Stainless steel will reflect sunlight and other light sources. I recall a few occassions when I was shooting my Ruger Red Label, that only has a dull finished stainless steel receiver, where the sun was starting to set in the evening and the sunlight was reflecting off the very small portion of receiver that was in my light of sight - and it was blinding! Another time I was shooting a nickle plated SW revolver and the same thing happened (nickle is obviously very similar to polished stainless steel). It was like I was holding a mirror in my hands and the sunlight reflecting off of the surfaces of the revolver made it impossible to sight the gun. Also, stainless steel or nickle sights on any handgun or rifle are useless - you need either black or other colored ramps and rear sights. (The only excpetion being the small bead sights on the front of shotguns, which are used as a reference point only and are usually a dull silver finish.)
Q:deflection calculations in a steel cylinder?
In most engineering calculations we have to make some assumptions about ideal behavior of a material otherwise we would not be able to simplify our equations to manageable sizes. Your steel cylinder (which I'll call a pipe) is made of a certain type of steel. That steel type has property tolerances listed in a steel manual to help you know about your steel before you begin. You'll need to know the cross-sectional area of the pipe and the weight of the TV to determine an average stress on the pipe. Obviously the weight of the TV is the force it generates. The force is its mass x gravitational acceleration. Since we typically think of steel as an elastic material, we think of it stretching like a rubber band or a spring. You pull it down with a TV and it deflects a certain amount, and will return to its original length when the TV is removed. It is typical to assume that all steel, regardless of its strength, has the same value for this elastic property. It is commonly referred to as the elastic modulus. This value will help you determine what type of strain occurs under what type of stress. So, once you have the stress, you can get the strain by using the elastic modulus. Once you have the strain you can determine the deflection based on the pipe length. Having the steel properties will help you determine how close your TV comes to stressing the pipe to its yield stress. If you reach a yield stress, your steel will deflect, but when you take the TV off it will not return to its original shape. I hope I've helped outline some of the things you'll need to do for the project, I tried not to give away specifics so that you can actually engage your brain around the project. Enjoy, learn a lot, and realize that this skill could easily turn into a career where you are designing projects that when done correctly save people's lives every day of the year.
Q:Ways to damage steel?
There are plenty of ways to damage/weaken steel... shear or tensile force, fatigue, temperature, corrosion, grinding, etc... there are even dozens of ways to do each of the things I just listed. But in the case you suggested, with the steel being very close to skin... a simple pair of bolt cutters would probably be the easiest.
Q:Question about building buildings with a steel frame.?
The steel is all custom fabricated in what are called structural steel fabrication shops. Each Building is designed by architects then the frame is designed by engineers to support whatever load is being applied to the building. After the engineering is done it goes out for a bid package where a fab shop estimates how much to charge for the fabrication of the steel and the erection of the steel. Once a company wins the bid, it then has to design how the steel will connect with one another and have it approved by an engineering firm to assure the connections are strong enough. Once all of that happens the fab shop orders raw steel beams and angle iron and steel plate at stock lengths. Beams are then cut into the right length and holes drilled in the proper places. The beam is then marked with a number that tells the erectors where it goes. The steel is then shipped out in batches to the construction site where it is unloaded and shook out into an organized place to grab them with a crane. They are then put together like a toy model, there are instructions that say what beam goes where and what size bolt to use. The welding you see being done is on really critical moments that need extra strength. That is about how it goes in a nutshell. It is a bit more complicated than that but it gives you an idea.
Q:Steel or Nylon strings for my guitar?
That's not an option Guitars are designed for either nylon or steel strings. They aren't interchangeable. Putting steel strings on a guitar designed for nylon strings WILL destroy the guitar. If you've already picked out the guitar you want, then you've already made your decision about nylon or steel.
Q:Is stainless steel good for a butterfly knife?
This isn't really a question for this section, but I'm still happy to help out since I'm a big cutlery nerd as well. One thing to look out for when buying a knife is a lack of specifics on what steel is being used. High Carbon Stainless Steel doesn't tell you what the steel is, just what it MIGHT be. Chances are it's something along the lines of 420HC or 440A, both of which are softer steels. They aren't the worst steels around, but they are very quick to dull. You'd be better off looking at the Balisongs of Benchmade. They'll cost more, but you'll know that you're getting something made with quality materials and that won't break on you. And if it does break for some odd reason, Benchmade's warranty and customer service are both fantastic. Although if a more questionable knife is okay with you as long as the price isn't too high, then at least 420HC and 440A aren't too brittle and will take a decent edge even though they'll dull quickly. As for whether stainless steel is good for a knife or not, that depends on the type of stainless steel and what you're going to use the knife for. Many stainless steels are more brittle than a carbon steel, so high carbon stainless steels are a bit more likely to rust but a little tougher as well. In a butterfly knife, a steel like that is a good way to go, although the steels used by Benchmade, as I mentioned, are of a much better quality.
Q:What happened to the comic book STEEL??? not the movie!!!?
Steel's own series was cancelled around issue #50, after which he went on to a co-starring role in Superman: The Man of Steel. Steel was eventually injured in a battle with Darkseid, at which time his niece Natasha took on the role of Steel. John Henry recently resurfaced in his heroic identity in 52, where he's been injected with Lex Luthor's metagene, making his body living stainless steel.
Q:Can I put nylon strings on my steel string acoustic guitar?
No, You will want a full size or possibly a 3/4 size guitar. A 3/4 size guitar is a little smaller and will be closer in neck width to a steel string guitar. I used one like that when I started out playing when I was young. Avoid the cheap ones on Amazon that only cost $30-$50.
Q:I am getting a benchmade mpr (m390 steel) and am unsure if it is a good knife look at the chart below?
From what I read M390 is relatively wear resistant, with very high stain resistance and good toughness. It is quite hard to qualify steel as better than other steel because it depends on many factors. E.g. for a small folder designed for delicate cutting D2 at high hardness would perform better, but if the environment is corrosive, like saltwater then M390 would be better. I'm not so sure about using stainless steels in large chopping style knives, but I've seen M390 used for them as well. Obviously hardness had to be lowered, which reduces edge holding ability, especially at low angles. Overall, it's a good steel, but if it will outperform S30V or D2 or 154Cm depends on heat treatment and blade geometry, knife designed use, etc.
