Description of Prepainted Rolled steel Coil for Construction Roofing
Prepainted Rolled steel Coil 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. Aluminum zinc coils 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.

Main Feature of Prepainted Rolled steel Coil for Construction Roofing

1.Corrosion resistance: It mainly depends on the aluminum protection. When the zinc being worn, the aluminum will  form a dense layer of aluminum oxide, resist corrosion material to prevent further corrosion inside. 
2. Heat resistance: Aluminum zinc alloy steel sheet has excellent heat resistance, can withstand high temperatures over 300 centigrade, and is similar with aluminized steel high temperature oxidation resistance. It often used in chimney pipes, ovens, fluorescent lighting device and the device cover. 
3. Heat reflective: Galvanized steel plate heat-reflective high rate is twice as galvanized steel, often used to make insulation materials. 
4. Economy: Because density of 55% AL-Zn is smaller than the density of Zn, so in the same weight and thickness of Galvanized zinc layer, aluminum-zinc steel plate is larger area more than 3% of galvanized steel sheet.

Q:What's the best dishwashing soap for stainless steel?
Jan is correct. You need to have some nickel in the stainless steel to prevent rusting, like 18/10 which has 10% nickel alloy in the steel.
Q:How to restore rusted stainless steel?
Nope, stainless steel is actually coated steel that can be removed by acid or scrubbing too much. it would need to be re dipped to go back to normal. would cost a fortune however.
Q:steel and heat treating?
Go to junkyard get old leaf spring, cut out knife, start sharpening. Why waste time heat treating steel when the spring steel as already be done.
Q:DUCTILE-TO-BRITTLE TRANSITION TEMPERATURE IN STEEL LOW CARBON?
Transition Temperature Of Steel
Q:What is Light gauge steel? is it same with light weight steel?
as a welder i can answere this. wel i think i can after 2 years of classes. so...light guage steel usually referes to the THICKNESS of the metal. also known as SHEET METAL. the only diffrences between light guage and roof truss is that a truss will be thicker metal ex- an i-beam for a structure is usually 1/2inch or 3/8 for smaller buildings. also there is no such thing as light weight steel. steel is steel the only thing that determins its weight is its size/thickness aluminum is a whole nother ballgame. ever see a pound of aluminum vs. a pound of steel? aluminum can be 1/2 or less the weight of steel. but its tensile strength suffers EX. say steel will snap at 70,000 pounds, aluminum will snap at 40,000 pounds, if it even snaps that is! it just tends to bend like rubber. aluminum is handy for many things because it will not rust.
Q:what's the difference between natural rolled oats oatmeal and steel cut oatmeal?
Old fashioned is the whole oat - the steel cut is oats all cut up. The steel cut is more mushy when prepared while the old fashioned has that good thick texture and feel to it.
Q:Why is stainless steel rust proof?
Stainless steel is an alloy of iron and other metals, notably Chromium and vanadium. You do not see it with the naked eye but at the surface of any stainless steel (SS) there are iron atoms and chromium atoms that are exposed. However, the chromium reacts preferentially to form an oxide. In essence, think of chromium sacrificing itself for iron so that iron will not rust. What a nice guy huh! This is called passivation just like most responders said. However, more than that the chromium oxide forms a tight protective layer that forms a physical barrier preventing Oxygen or any oxidant to reach and attack the iron underneath it. Also, the chromium oxide formed is not FLAKY and porous, so it does not mar much of the surface as an iron oxide (rust) would. For science project, you may not make it too technical but you can make a reference or make an ANALOGY of rust prevention to high school or social situations as being there for your friend or classmate But in real life, when the odds are too great, that protection afforded by chromium may not be enough. Because eventually all steel exposed to very oxidizing atmospheres will rust. Just a little break in the surface is enough to start the process of rusting.
Q:Why low carbon steel have poor magnetic properties?
The composition you mention is not a low carbon steel.The carbon and manganese content are high enough to mean that the crystal grain size will be small. A very large grain size is needed in steels for transformers,motors etc.The large grain size and lack of carbides in low silicon steels for magnetic purposes allows the easy movement of magnetic domain walls.Transformer steels typically have a carbon content of about 0.003% and 3.5%Si with the phosphorus and sulphur at a tenth of the levels you mention.The high Si content increases the electrical resistivity of the magnetic core and reduces the power loss from eddy currents(the core metal has voltages generated in it by the changing magnetic fields) and the power lost in eddy currents heats up a transformers core so it needs extra cooling;the loss is inversely proportional to the resistivity and 3.5%Si increases resistivity of iron by a very large amount.The presence of high silicon with ultra low carbon and manganese level allows the soft magnetic steels to be annealed at very high temperatures(850 to 1100deg C)without a phase change so that the crystals have 10,000 to 10,000,000 times the volume of the crystals in heat-treatable (Just)steel you mention.Fine for playing with and demonstrating electromagnetism but not as electrical engineering feedstuff.
Q:Sandpaper versus Steel wool?
Steel wool and wax is for the final buff after the finish coat. Sanding will scratch the finish and should only be done before the finish coat. Steel wool and wax have been used as the final finish to remove rough areas and buff the finish for a long time.
Q:Steel Research?
Your okorder.com (they make steel deck and steel joists) There are thousands of other items routinely produced from steel, including rebar, and all the metal in cars, airplanes, and about a million other things.
