Product Description:

Hot-dip Zinc Coating Steel Building Roof Walls 
1.Structure of Hot-Dip Galvanized Steel Sheet Description

 It offers the economy, strength and formability of steel combined with the corrosion resistance of zinc. The hot-dip process is the process by which steel gets coated in layers of zinc to protect against rust. It is especially useful for countless outdoor and industrial applications.

2.Main Features of the Hot-Dip Galvanized Steel Sheet:

• Smooth and flat surface

• Workability, durability 

• Excellent anticorrosive property

• High strength

• Good formability

Q:Why can't the coil weight be too low?
Because the steel coil is stored in warehouse stacking level, if the coil weight is too low, resulting in a single coil capacity is reduced, so that the steel roll easily crushed and deformed;
Q:stainless steel cookware sticking?
Food sticks to stainless steel. Gourmet cooks love it for that very reason. Without sticking, foods won't sear properly. For the rest of those cooks out there, nonstick is often an easier option. If you want to make a go of the stainless, here are some tricks of the trade.... a)always preheat the pan on low-medium b)never put cold food into a hot pan. It will stick worse.Leave cold food on counter for 15 minutes before it hits the pan. c)after preheating the pan, add oil, or an oil/butter combo d)for foods like eggs, potatos, grilled cheese, nonstick is your best friend. e) when you take food out of pan, immediately wipe the pan out with a kitchen towel. Keeps cleanup from being a nightmare. f) don't wash pans in sink while hot. They will warp. Stainless takes some getting used to. Hope this helps!
Q:Urine dulls too shiny stainless steel?
Stainless steel will rust under proper conditions. I live on a boat on salt water, trust me. If the urine works it won't be prone to rusting any more than before. It's not the shine that inhibits rusting with stainless steel, it the % of carbon in the steel, compared to regular steel. IF the urine works it's because it is acidic (a mild acid). Wash it with a small brush and some baking soda to neutralize the acid when your done. A much stronger acid would be swimming pool acid. (Muriatic acid) but be careful you might test a spot with a Q tip on the back. If you try Muriatic acid it would take seconds.Then wash in baking soda water to remove all acid.. SS
Q:question about swords steel?
Steel grades generally tell you how much carbon is in the steel. The higher the number the more carbon. Aside from quality of manufacture, the better swords tend to be 1060 or more. Few quality swords are made from 1045. Which DOES NOtT hold an edge better (quite the reverse). Swords made of these different steels weigh about the same. That is, if you made two identical looking swords - one of 1095 the other of 1045, they would weigh the same. 1045 is only more commonly used because cheaper swords tend to be made from it. Edit: No real swords are made from stainless 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:Question about the strength if steel?
There are many types of steel some very rigid, while you can have steel that is very flexible. The type of katana: steel is for Samurai swords
Q:Where can I find an atomic structure of carbon steel?
This Site Might Help You. RE: Where can I find an atomic structure of carbon steel? What website can I use to find a good picture that shows the atomic structure of a carbon steel?
Q:Coating on Steel Wool?
spun steel fibers have a microscopic coating of oil to prevent them from rusting. Rusting steel wool wouldn't sell very well. I would think that removing this oil could be accomplished with any good degreaser, like brake cleaner or the like. However, I've never tried this before. In science class they perform experiments by removing the oil with vinegar. After wringing out the steel wool pad, it is wrapped around a thermometer and placed in a sealed jar. After a few minutes the temperature rises because of the chemical reaction that takes place when four atoms of iron react with three atoms of oxygen and create two atoms of iron oxide - RUST! You can unwittingly recreate this experiment by using steel wool in the process of removing one or more layers of finish from a piece of furniture Hope this helps
Q:How can i make difference between iron and steel?
Iron is a chemical element with the symbol Fe, that has no engineering application as it is very soft. You are not likely to come across a piece of metal of pure Iron. Steel is an alloy of Iron that is widely used with different types for various application. The type depends on the alloying elements. An old and rough way of identifying them is to use a chart, that shows the spark pattern when they are subjected to grinding.
Q:shinning ammo with steel wool?
* Yes, but I use both fine steel wool and Liquid Brasso Metal Polish on mine.* You can buy it at any Hardware and I believe Walmart carries it.* Great stuff.*
