1.Structure of Prepainted Galvanized steel Coil
With Gi as base metal, after pretreatmet (degrease and chemical treatment) and liquid dope with several Layers of color, then after firing and cooling, finally the plate steel is called pre-painted galvanized steel ( PPGI) .Pre-painted galvanized steel is good capable of decoration ,molding, corrosion resistance
2.Main Features of Pre-painted Galvanized steel Coil

1) Excellent corrosion resistance: The zinc layer provides a good protection of Pre-painted Galvanizeed Steel Sheet.
2) High heat resistance: The reflective surface of the material aids in efficiently reflecting the sunlight away and in turn reducing the amount of heat transmitted. The thermal reflectivity converts into energy savings.
3) Aesthetics: Pre-Painted Galvanized steel sheet is available in plethora of patterns and multiple sizes as per the requirements that given by our customers.
4) Versatility: can be used in the various areas

- Q:Will a stainless steel ring rust, or tarnish?
- Stainless Steel does not rust...that is why it is used in our kitchens and the top kitchens of the world...!! sorry...Stainless Steel does not Tarnish either!
- Q:Steel Garage...........!!?
- The entire garage is steel? Garage door? Are you able to open and close it without too much trouble? If so, just keep it lubricated. You could paint the door to improve its appearance.
- Q:Which is more reactive? Zinc or Steel?
- Zinc. Steel is an alloy consisting mostly out of iron, In the reactivity seris, zinc is more reactive than iron. Therefore, zinc is more reactive than steel
- Q:how steel structures can withstand earthquake?
- Some buildings are built on giant springs so they wobble when there's an earthquake but don't try to ride it out.
- Q:Mild Steel furniture finishing?
- No, I don't think the oil will do what you want. I have heated and quenched metal in oil several times (to harden it) and it did not give a finish to steel. I have heard of heating steel to a high temperature (red) and putting powdered sulfur on it, it will make a black finish. BUT, sulfur stinks and you would not do this indoors. And I don't know what the results would be like for indoor use. At the hardware store, you can find something like POR (paint on rust), a brand name of rust neutralizer. There are others. You spray it on (or paint) and it will turn rust into a glossy black material. Other than that, I think paint is your best option. Check out the new finishes they have now, if you haven't checked, they have come a long way. If you let them dry completely (in the sun) the spray can finishes are very durable. Good luck! Ooops, I forgot about gun finishes. Yes, some are blue, you might be thinking of that, but that is only if you put several coats on. One coat might do it. Plus, there are other colors, such as black (see the parkerizing link on the list). Here is a good company, they can be lots of help, too.
- Q:What is mild steel and what items are made from it?
- not really. Coins aren't usually made from steel (e.g. an US cent is mainly zinc which will melt with releasing toxic fumes while welding), spoons are usually stainless steel (which is not mild steel), bottle caps can be steel but also aluminum. Fasteners can be made from a wide variety of metals. Generally mild steel is steel with a relatively low content of carbon (2%) which makes it easier to weld. It's used a lot for structure in building (e.g. rebar). Mild steel is also cheaper than other kinds of steel. Tools are usually made from high carbon steel. Generally I'd recommend to go to the scrap yard and pick up some shapes and pieces you like if you don't mind having to clean the rust off. Most will be mild steel. Welding small and thin pieces is much more challenging than welding larger pieces of metal. You are more likely to melt a bottle cap than weld it. Also your steel needs to be clean (no paint, sandblast or brush rust off). I would highly recommend to talk your project over with your teacher before you get all frustrated.
- Q:Handgun steel question...?
- The chrome moly alloy used in blued steel guns is the strongest thing out there today. Stainless guns sacrifice a little in strength in exchange for their rust resistance. Every maker has their own special alloys for various parts as well as proprietary techniques for hardening and tempering depending on the use a part will be put to. Keep in mind that the harder you make steel the more brittle it becomes. Especially true in knife blades also. A custom knife blade could be made much harder than they are, but would shatter under hard use.
- Q:Help with Steel and Iron please?
- Steel is an alloy composed of mainly iron and carbon. Pure iron is very rarely used anymore. Depend on the concentration of the carbon, you can get from wrought iron to high grade steel. For stainless steel, Chromium is added to the alloy to prevent rusting. Just go to wiki. you should be able to find a lot more about it
- Q:what is best cookware? stainless steel or iron?
- I have a combination of them both. I have Le Creuset enameled cast iron dutch-ovens, pots and pans; as well as All Clad stainless steel saute and deep-rimmed pans which have a copper core. I have one non-stick pan that I use for cooking eggs in.
- Q:Is it me or is everything steel in pro wrestling?
- The guard rails have to be steel or fans would tear them apart. The steps have to be steel..( although they are not 'solid steel'), in order to hold all that weight of people going up and down them for an entire show. The chairs are very forgiving. All in all, I can see where you are going with this, however it has been this way for decades now. Notice there are no steel tables or steel announcers desks?
