product information

The Galvalume is a kind of coated steel coil/sheet. With the cold rolled steel of different strength and thickness as substrate, it is produced through applying Al-Zn coat on both faces by hot dip process. In its coating, Al accounts for about 55%, Si 1.6%, while the remaining is Zn. It enjoys both the physical protective feature and durability of Al and the electrochemical protective property of Zn. And its surface has bright silver color and regular embossed-like figure, which are highly decorative.

Q:How does stainless steel soap work?
Many metals have germicidal qualities. Silver is the strongest germicide of the metals, but a sterling silver bar of soap would be expensive and it would tarnish. The tarnish would actually not affect the silver's ability to kill bacteria, but it would look bad and the tarnish would turn your hands black, so people wouldn't want to use it. Many people even take silver internally in the form of Colloidal Silver, but Colloidal Silver is very controversial. Yes, it kills many bacteria, but it can also cause a person's skin to permanently turn blue...a condition called Argyria. Brass actually is a better germicide than stainless steel...but again this is a cosmetic problem. Brass tarnishes, so people wouldn't want to use it. Stainless steel is actually a very weak germicide, but even steel has some ability to kill germs. Stainless steel also removes fish odor. My son has a stainless steel bar that he takes along when he fishes to remove the fish smell from his hands. There's nothing magical about the bar...a stainless steel spatula would would just as well, but the bar is more convenient to carry. I'm not sure if this is scientific enough or not. -
Q:Which is stronger, Wood or Steel?
Back when I was in school we used to have a contest comparing balsa wood bridge designs. The idea was to build the strongest bridge when derated for bridge weight. The strength test was that the 2-ft long bridge was placed between two tables and a garbage can was strung up to the middle of it. Then it was slowly filled with water until the bridge snapped. The can was weighed and divided by the bridge weight to get our scores. I don't see why you couldn't do this to compare wood vs steel. You could find how much load is needed to snap sample rods. The important point is that the rods should be nearly identical in dimensions between the two materials-- this means length and diameter. Also if you're measuring steel, you'd want to choose a relatively thin diameter or a long span or you won't be able to even bend it. Also while I'm pretty sure wood will snap, steel might bend gradually, so you'd have to decide how much deformation you would allow before calling the piece failed. Also if you take this approach be sure to wear safety glasses when running it. In fact it would be a good idea to put a metal shroud around the test structure.
Q:Can I load my own steel core ammo?
You don't know the law regarding selling steel core ammo quite as good as you think you do.
Q:stainless steel cookware sticking?
You sure it's stainless steel? Quick test, is to put a magnet to it. Stainless steel won't stick to a magnet,Sorry your meal turned out icky. Bye
Q:pedal steel guitar...?
I agree with everything that Lester said. Another thought is to consider starting on a lap steel guitar rather than a pedal steel - its related, a little easier to learn on, and less expensive. Once you get proficient on the lap steel, you can move up to the pedal steel. Good luck!
Q:Are a guys balls really made out of steel?
it is extra of a euphemism than actuality. somewhat the testicles are somewhat gentle and may even herniate or rupture; it somewhat is why they cover those balls of steel with athletic cups earlier they actually take the sector.
Q:Can carbon steel be solution annealed?
No. Carbon steel has two different crystal structures, FCC and BCC , depending on the temperature. when you heat steel up and then quench it, it locks the crystal structure into the BCC form. this makes it hard. whereas precipitation hardened austentic stainlesses remain BCC regardless of the temp, so the hardness change is not a function of thermally induced strain. you can anneal carbon steel but the thermal profile is closer to the precipitation profile of PH stainlesses than it is to the Solution annealing profile.
Q:Casting Stainless Steel?
You have 2 options. Sand casting or investment casting. Stainless steel can be cast with either of these methods. In either case a model or pattern will have to be created. For sand casting the pattern is all that is needed to go to casting. For investment casting the pattern is used to make a wax casting, which is then coated with the investment. The wax is burned out and the metal is then poured into the cavity. If you are making just 1 or 2 pieces you can have waxes machined. This saves the intermediate step Depending on the size machining may still be your best option. Especially if you want just 1 part.
Q:Which one is better to start? Steel or Acrylic tapers?
Steel
Q:How to sharpen a knife with the stone and the steel?
The site listed above gives you a great step by step procedure on how to do this yourself. A Sharpening Steel is used to sharpen the fine edge of a knife. Many knives only need this done to have a refined edge. Any fine edge of a knife can have minor burrs that occur with normal use. To sharpen this type of edge, merely run the knife at an approximate 7-8 degree angle, away from yourself on the Sharpening steel repeatedly (no more than about 8-10 times each side, alternating each side as you go). Give the knife a quick wash, to remove any unwanted detritus, and you are ready to go. If you want to resharpen an entire knife, use a wet stone. Remember some stones have a natural oil in it, some do not. If you are already using a stone with oil, continue to use it with Mineral Oil as the lubricant. If it is a dry stone, use warm water. You'll never be able to change a stone once you use oil. Make sure its as flat as you can. Wet it with warm water, or the mineral oil, rub the knife away from yourself (on the coarse side) at a 5 degree angle on both sides. Alternating sides approximately 20-30 times each. Flip the stone over (dry finer side), and at a 6 degree angle, rub the knife blade toward you on both sides approximately 10 times on each side. Using either your Sharpening steel, or 550-600 coarse emory paper, rub the knife away from you 5-7 alternating times on each side at about a 7-8 degree angle. Clean the knife well. You now have a VERY sharp knife that will require this entire treatment ony 2-4 times a year at most. Otherwise, keep using the sharpening steel. I GUARANTEE this works best.
