Product Description:

Brief Introduction

1. Prepainted Galvanized Steel Coil is coated with organic layer, which provides higher anti-corrosion property and a longer lifespan than that of galvanized steel sheets.

2. The base metal for Prepainted Galvanized Steel Coil is HDGI Steel. The finish coats of Prepainted Galvanized Steel Coil can be classified into groups as follows: polyester, silicon modified polyesters, polyvinylidene fluoride, high-durability polyester, etc.

3. The production process has evolved from one-coating-and-one-baking to double-coating-and-double-baking, and even three-coating-and-three-baking.

4. The color of the Prepainted Galvanized Steel Coil has a very wide selection, like orange, cream-colored, dark sky blue, sea blue, bright red, brick red, ivory white, porcelain blue, etc.

5. The Prepainted Galvanized Steel Coil can also be classified into groups by their surface textures, namely regular prepainted sheets, embossed sheets and printed sheets.

Q:Consider an experiment in which an aluminum soft drink can and a steel soup can are left outside for a few da?
I'd expect appearance of reddish dots or stains of rust on steel, while aluminium should stay virtually unchanged. Explanation: Both materials oxidize in natural environment because of atmospheric moist, but in very different ways. As for steel, oxidation begins as reddish dots of rust which grow and become stains. Oxidation then progresses in depth causing decay of material, compromising its strength and structural integrity.
Q:how do I build a steel galvanizing plant. Hot dipped Galvanization?
How big of a kettle do you want to go with? A small 6-10 foot kettle would work fine for spinner work (small parts ran in baskets) but if you want to handle large beams and so forth you will need to have at least a 25 foot or longer kettle. You will need tanks for caustic,acid,rinsing,and preflux solutions. If you go with sulfuric acid it will have to be heated. The caustic and flux tanks need to be heated in any case.You will also need a bag house to control smoke coming off the kettle. First you should look into permits such to see if you can actually build this plant. Galvanizing is nasty work and the laws and regs are strict. Former Kettleman
Q:Steel or Iron? (stupid 20 characters thing)?
steel is harder than iron Iron is a chemical element. It is a strong, hard, heavy gray metal. It is found in meteorites. Iron is also found combined in many mineral compounds in the earth's crust. Iron rusts easily and can be magnetized and is strongly attracted to magnets. It is used to make many things such as gates and railings. Iron is also used to make steel, an even harder and tougher metal compound. Steel is formed by treating molten (melted) iron with intense heat and mixing it (alloying) with carbon. Steel is used to make machines, cars, tools, knives, and many other things.

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:i need help about stainless steel?
Weathering steel will rust, but the rust will be adherant and not flake off and be replaced by new rust. Therefore once it rusts it will pretty much stop rusting any more. One (severe) down side is that anything around it will be streaked with rust stains and it will look awful. Some bozo with the Texas Department of Transportation designed a number of freeway interchange overpasses here in Houston using Cor-Ten steel and all of the concrete supports are streaked with red rust stains and it looks like hell. Cameron built an office building here in Houston with a Cor-Ten facade and it is streaked with rust too. They should have gone ahead and spent the money and painted them, but they didn't.
Q:whats the difference between weld steel and sheet metal?
Most sheet metal is coated with galvanizing. Not fun to weld on. Most steel for welding use is just carbon steel.
Q:What is the best brand of stainless steel sink?
Yes, it’s a good idea to look for the best brand of stainless steel sink as it is used in various purposes regularly. Top brand of stainless steel is naturally longer lasting and capable of bearing lot of pressure then normal stainless steel sink. You must see top brands as well as their prices before buying any.
Q:What is stainless steel 316, and what are its properties?
For machined aspects 416 cautioned. For welded aspects 316 is cautioned. besides the shown fact that 316 supplies a greater advantageous corrosion resistance. oftentimes the only benefit for 416 is machinability others than that 316 is greater advantageous
Q:shinning ammo with steel wool?
Jonathan, You won't have any problems firing the brass after you clean it with a solvent(such as brake clean) and steel wool. Keep in mind though, that brass is a soft metal. Use a less abrasive steel wool, such as 0000 to ensure you don't take too much brass off. Also, if you want your brass to be shiny, 0000 will ensure you won't have deep scratches in the brass. On a different note, there is a product called 'Flitz' that works great for polishing and cleaning up metals such as brass. It uses small abrasive particles in a liquid to polish and restore a bright finish. The ideal solution would be to run the brass through a tumbler or sonic cleaner. However, if you've only got a few cases and don't plan on using it that often they can be a bit pricy. Regards, Dustin All of the previous also applies to steel cases(just noticed they were steel), just add a good rust preventative and ensure the cases don't show any current signs of rusting as cleaning them up will most likely clean off any prior rust inhibitors. A rusted case is NOT safe to shoot.
