Product Description:

We can supply prime quality,competitive price,timely delivery and various payment terms!

The main technology of Galvanized steel sheet is proceeding by the chemistry degrease and electroanalysis with the cold rolled steel coil and sheet ,clean the oils on the surface of steel, sufficiently heated to the proper temperature for zinc coating, pass by level up, strain rectify , and then passivation or annoit etc.. Hot dip zinc is in order to improve anti-erode and prolong the usage period of material, at the same time it can beautify the surface and add arty.

Our hot dip galvanized steel sheet is widely used in such field as light industry, electrical home appliances, motorcar and construction.

Q:What company sells strong steel doors for homes?
You can find strong steel door here...
Q:steel or aluminum? I'm looking to try a steel mtb for first time?
Im a huge fan of steel frames. #1. they dont feel like they are bouncing off things like aluminum #2. they absorb more vibrations #3. they can be fixed if you wreck them #4. They dont weigh much more (if anymore) then aluminum #5. you are in a very limited clique #6. a steel frame will far out-live an aluminum frame. #7. it doesnt sound like your riding a tin can. #8. break a hose or cable guide, and you simply can take it down to your local muffler shop and have them weld one back on.. an aluminum frame is so fragile it will probably have to be replaced. Aluminum frames do have their pluses. #1. they are very stiff #2. you dont have to worry about rust #3. every company on the planet makes aluminum frames so they are easy to find... #4. looks. because aluminum is so stiff, there are some very radical frame designs. steel frames are just boring to look at. if you like steel frames, you wont want to go to aluminum. if you like aluminum, you could consider steel.
Q:what coating can be used on steel so it wouldn't rust when exposed to sea water?
Galvinized means steel with a zinc coating. It is the best. For boats at port, and other fixed objects this can be supplimented with cathodic protection, an electrical method that substitutes corrosion of a sacrificial anode for the rusting of the steel. Epoxy and other coatings tend to be very temporary as they wear and scratch with use and lose all effectiveness if they cannot exclude seawater from contacting the bare metal. Zinc responds to abuse and can 'heal' over minor dings. The zinc is refreshed by periodic painting with a high zinc content paint or by electroplating.
Q:Stainless steel water bottle? ?
The problem with stainless steel water bottles is the steel takes even longer to decompose in our landfills then plastic its self. So it just adds to the waste. If you use steel be sure to recycle it when you are done using it. Another problem is the fact that we don't really make steel here anymore so you have to pollute the environment shipping steel here that the bottles are made from. It gets ship here on trucks, ships, and what not. Very big polluters!! You'd be better off just getting a reuseable bpa free plastic water bottle made in the usa. Or some of those expensive corn cups.
Q:Is boron steel harder?
The only thing that affects the hardness of steel is the carbon content. But there are many elements that can make it easier for a steel to achieve its maximum hardness. And Boron is an extremely effective element that increases the hardenability of steel. Adding as little as 0.002% Boron can have a big impact upon quenching of a steel. Boron is usually added when you need the hardness of a heat treated steel part to extend deep below the surface. For example, lets say you had a two identical plain carbon steel parts, but one had boron and the other didnt, and you wanted to heat treat them both After quenching, the surface should be the same on both, and lets say its 55 Rockwell C. In the plain carbon one, the hardness might drop down to 50 at 2mm under the surface, but the boron treated one might not drop to 50 until 4mm under the surface. Now, these numbers were completely made up, and it would depend on the specifics as to what the difference might be.
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:How to wear out stainless steel?
Its called stainless for a reason :) many grades are out there, 300 400 series. You could use acid to make it look older but you wouldnt want to cook with it after chemically converting it with acid.Personally i like cast iron. It will last a life time + and looks very cool. Sorry no safe way to do it and cook with it. B^
Q:How hot does steel?
Type your query into Yahoo! Search or other search engines to get the answer: It depends, since steel usually has different metals added for various properties (strength, corrosive resistance, etc.)
