Product Description

Pre-painted steel coil/Color coated steel coil


Pre-painted steel coil is coated with organic layer, which provides higher anti-corrosion property and a longer lifespan than that of galvanized steel sheets.

The structure of pre-painted steel includes finished coating, primer coating, chemical conversion coating metallic coating and cold-rolled steel.

The pre-painted steel sheets are mainly provided for various commercial purposes covering architectural construction, electrical household appliances, transportation, etc.

Q:runescape steel legs?
Steel legs are popular smithing items. Maybe a lot of persons are selling them at lowest price too so yours don't get sold. Plus, no one really buys steel legs.
Q:What is the difference between steel and iron?
Steel is a refined, alloyed metal that is mostly iron. Iron, in a chemistry sense os simply Fe. In an industrial sense iron is pig iron commonly saturated with carbon, up to 4.5% and has other impurities like sulfur. Pig iron is brittle and should break rather easily, and bend very little. After a piece is broken look at the crystal structure, you should see rather small crystals. Most steel made for car body's, washing machines, file cabinets, low grade bolts and nuts etc. should flex and bend before breaking. Most steel made for things like cutting tools, axles, etc, is hardened and will chip and break rather than bend. Also you can try to heat the piece to a glowing orange temperature. It must be very hot. Cool it. If there is a lot of white flake scale on the piece it is impure and probably iron of some sort. In the end the only way exactly tell is have an analysis done and look at the chemistry.
Q:what coating can be used on steel so it wouldn't rust when exposed to sea water?
egg yolk. it really works. i know this because i built a surfing bicycle (yeah) that had steel on it.just let the steel soak in the yolk for about 3-4 hours and let it dry in a dark area. this will work.
Q:Stainless steel kitchen sink cleaning and polish?
A stainless steel kitchen sink is durable, easy to keep clean and disinfect, and will only grow more beautiful with age - if you take proper care of it. Clean the sink with soapy water, or a stainless steel cleaner (Spray N Sheen Stainless Steel Cleaner/Polish/Protectant) once or twice a week. Once or twice a month, fill the sink half full with a 50/50 solution of bleach and water or a special stainless steel cleaner (Stainless Steel Cleaner). Let it soak for about 15 minutes, then wash the sides and bottom and let it drain. Remember to wipe dry when done.
Q:Steel String for Classical?
If the guitar was designed for nylon strings, then don't put steel strings on it!
Q:Steel Tensile Strength?
I don't follow your calculations. It seems to me that the piece you show could be made from .01 steel and still be less than a pound. Also, it is hard to get steel thinner than .015 because anything thinner is not very useful. If you made it out of .015 steel and used a high strength steel, it might be useful. You wouldn't be bashing any skulls, but with some spikes on the end, it could do some damage, and protect against knives or other hand weapons. You also won't get any bullet resistance out of anything that thin. If you want to bash skulls and deflect bullets, you have to get up to at least .10 and several pounds. Any weight on your hands slows down the speed of your punch, but this is compensated for by the increased energy of impact carried by the extra mass. Also, having something hard to protect your hands allows for harder hits and more damage to the opponent. An interesting idea, but it would take some testing to figure out the optimum configuration. One problem I see is that it completely encloses the hand, making it impossible to use the hand for anything else. So you would have to put it on and take it off a lot, and there would be cases where you wouldn't be able to put it on when you needed it. For that reason, I would not wear two at one time. I would make it heavier and wear it on one hand for bashing skulls and deflecting weapons, and keep the other hand free for other things.
Q:Why buy recycled steel?
Where you buy all your steel. The recycled and new steel are indistinguishable from each other. You won't recognize the one from the other. Same thing with glass. A certain percentage must be used glass, to enhance the quality of the total batch. Peace.
Q:Do you think there is a way to mix liquid concrete and molten steel/metal to create solution that is stronger?
Mixing hot steel with liquid concrete would be very hazardous to your health. Steal in a molten state would flash the water in the concrete mix into steam and the steam would blow concrete and steel out of your mold. This would be about like being shot with a shotgun. This occurred in a steel mill near me some years ago on a rainy day when some steel splashed from a ladle and landed on a puddle of water, part of the siding was blown off the building and one worker sent to the hospital.
Q:Guitar strings, nylon or steel?
You have TWO acoustics - one a classical with nylon strings and another with steel strings. Nylon strings are always easier to play as the tension is lower and the top tree strings are thicker than their steel equivalents and so cause less pressure on the finger tips. Whether the action of your steel string is too high or not is impossible to say without seeing it. The two types of guitar produce different sounds - i like the sound of both and like you, have examples of each. Personally, I wouldn't want to play a guitar with what I thought of as an inferior sound. The choice has to be yours though.
Q:Is Carbon Steel a Metallic Material?
Steel with a lower to medium level of carbon will typically be reserved for metal sheeting for use in construction, due to its increased hardness and malleability.
