Product Description

PPGI: 

1, Introduction: Color coated steel coils(sheets), i. e. PPGI, also called prepainted steel coils(sheets), are made of galvanized steel coils(sheets) with polymer coatings as surface. It's a new enclosure material and building board with characteristics of light-weighted, heat preserved&insulated, easily installed with bright colors. 

2, Production Process: Pretreatment(Degreasing)_Drying_Chromating_Paint Basic Oil_Cooling_Drying_Color Coating_Cooling_Film-covering_Rolling Up 

3, Characteristics: 
Good at corrosion resistence. Besides zinc coating of the basic plate of galvanized steel sheet, the color coating as the surface has double lifetime to ensure better anticorrosion effect. 

with excellent cold bending molded manufacturablity, PPGI products can be processed or directly used as final product. As being light-weighted and conveniently transported, they're widly used to replace wood to save energy. 

There're thousands of colors can be chosen as per different application. Any color plays well in decoration. 

No pollution with high recycling rate, PPGI coils and sheets are strongly recommended as enviroment-friendly products by the government. 

4, Appliance: Thanks to the above characteristics, color coated steel coils and sheets are widly used in construction, furniture industry, transportation industry, ect. 

5, eye bands and 4 circumferential bands in steel, galvanized metal fluted rings on inner and outer edges, galvanized.

Q:Does stainless steel watches rust?
Stainless Steel comes in many different grades, a prime example is to see if a magnet sticks to it if so it has a high iron content as the grade of the stainless increases its magnetic ,iron properties decrease have you ever left a stainless knife, fork, spoon in a kitchen sink for a few days it will show evidence of rusting most jewelery is low grade stainless as it does not need to to be suitable for medical grade or marine grade quality under normal conditions wearing your stainless steel watch will not make it rust however if you were to leave that watch in contact with another metal and they are wet then yes it will rust as it will create a chemical reaction.
Q:how hot is white hot steel?
I had the Odyssey white steel # 5 and absolutly hated it. I gave it away. I didn't like the feel on lag putts. I now putt with a Scotty Cameron Circa 62 #2 and I love it. Would highly recommend a Scotty Cameron for anyone.
Q:grain growth in steel?
Well, I can't answer the question for you because, if the press bending is done cold, the grains will not grow (at least not with normal steel alloys). One wonderful thing about metallurgy is that the real answer is it depends because there are all sorts of weird and unexpected things that can happen. Cold work (which is what press bending is unless it is done hot or the amount of deformation is extraordinary high and fast so the metal heats up a lot locally) adds stored energy (strain energy) which provides one of the driving forces for recrystallization. Recrystallization is not a yes/no process, it is a process that happens as a function of time and temperature. Recrysallization of a cold worked structure will refine the grain size if done properly but the final stage of recrystallization is grain growth and you can end up with a larger grain size than you started with. The other thing that can affect grain structure is the deformation itself. There are all sorts of transformations that can happen due to the deformation process (twinning/martensitic is one) but, again, these don't usually qualify as grain growth. It may be that the question was incomplete, maybe the question is how does the press bending affect the final grain size after a subsequent anneal? The metallurgy of steels is fascinating because there are so many different microstructures that can be produced, hundreds (or thousand) different alloys, equilibrium and non-equilibrium phases based on composition and thermo-mechanical processing. Hope this helps
Q:knowledge of steel composition?
You have opened a can of worms. Specific types of steel vary not only by composition but by the way they were made, their physical properties and their morphology (microscopic structure). The composition you have given would fit for High Carbon Steel and Medium Carbon Steel. Go to the reference I've given, it allows you to put in 3 of the components of your alloy and then it gives you a list of possibilities. You can open each candidate individually and see the full composition. Hours of fun. :)
Q:Stainless steel scrubber?
I posted this earlier to a similar question... Really burnt on gunk in the bottom like milk or blackened food can easily be cleaned out of stainless steel pots and pans by sprinkling baking soda in the bottom, covering with vinegar, let simmer with a little water for 5 min. Let cool, scrub out with a vinyl scrubby. or I use a lot of stainless steel for cooking and over the years have found a very inexpensive solution to cleaning them especially the ones with burnt food stuck at the bottom. I use Used fabric softner sheets (sheets that i have already used in the dryer for my clothes) and have them soak in water in the dirty pan overnight. Next morning i use the same sheet as scrubber to clean the pan and all the burnt food comes off easily leaving a new look to the pan. Try it this works.
Q:Pipe screens: brass or stainless steel?

Q:Why does stainless steel get rusty?
You can rub the rust off with anything, from steel wool to Ajax. Although if you've previously used steel wool to clean it, that could be why it rusts. We had that problem manufacturing stainless steel railing and had to put it together on an aluminum table and polish welds with grinding wheels that never touched steel. What rusts are steel particles picked up on the stainless surface. Another possibility is that some stainless is more magnetic and usually also heat-treatable. It has just enough chrome in it to classify as stainless but can get minor surface rust. Not nearly as much as plain steel, though. Use a scouring powder like Zud or Barkeepers Friend and a cloth or sponge to polish if it's a sheetmetal surface rather than a bar grille, because these have oxalic acid and no bleach. They don't leave corrosive traces of chlorine behind. In fact, oxalic acid reduces rust to iron powder. Which is really neat if you need to clean a small rusty item--stir one of these powders into water, drop in the rusty piece and check it from time to time. Rinse off any abrasive powder, dry it well and oil it. When the rust is gone, it leaves a fine matte finish behind.
Q:Soldering Steel Wire?
You can indeed by using the correct flux as normal soldering fluxes as used by plumbers will not work. I believe to solder steel it requires an acid flux which will corrode copper so when its done make sure its well cleaned afterwards and if possible apply a corrosion proofer afterwards ie paint or even petroleum jelly. I am curious as to why you would want to solder wire to a steel nail.
Q:What are steel cut oats?
These are oat grains that are cut with steel sheers intstead of being put the a roller processing system . These are most favored for making true oat porridge . If you really hate preparing breakfast , purchase some of these . Place them in your crockpot over night with milk or water ( your choice ) add what you like raisins cranberries , nut other dried fruits turn on low . Breakfast will be ready and waiting when you get up in the morning just make the coffee or tea . My favorite is to mix in milk , shredded carrot , dried cranberries , b. walnuts and maple syrup . Note : contrary to my predecessor , these have more nutritiional value as they havenot been so heavily processed . Quick and instant oats are just a waste nutritionall speeking . Anything that must be fortified has been over processed .
Q:steel plow?
If you're willing to substitute the word iron for steel (steel came a good bit later in history), the Girard plow from the 1300's in Belgium would be the first example known. It's named after the guy who invented it (Girard). How did it work? Like any other plow! You drag it along and it makes a trench of sorts in the ground! It was used for agricultural purposes. As for how it was produced, you need to look up the history of the Iron Age to understand how they started to use iron back in about 1200BC to make tools.
