 color Rolled Galvalume Steel Coil for Roof

Description of Color Rolled Galvalume Steel Coil for Roof
Aluminum zinc coils 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 Color Rolled Galvalume Steel Coil for Roof

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: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:i want to see the atomic structure of carbon steel?
This is actually a quite complex question... The atomic arrangement in steels can be controlled over a pretty wide range of different structures. This is really the fundamental reason why steel is such a commonly used material. The different atomic structures produce different physical properties so metallurgists have developed many different processes to control the atomic structure to get the properties they want. One simple answer is that Fe is BCC, body centered cubic at room temperature at equilibrium conditions. When you heat Fe up, it transforms to FCC, face centered cubic. If you continue heating Fe, it goes back to BCC, then it melts. The addition of C makes these structures (and the transformation temperatures) different. Deviating from equilibrium conditions by, for example, cooling very quickly (quenching) creates different atomic structures (one of the most important is known as martensite). Depending on how much C is in the steel, you can also have two different atomic structures (two different phases) present in equilibirum, for example, pearlite which is a mix of alpha Fe (BCC) and iron carbide Fe3C (orthorombic crystal structure). So... you need to think a little more about exactly what you want a picture of. I hope this helps
Q:Does anyone know about steel framed houses?
Steel frame houses are built using a modern method of construction (MMC) with an impressive strength to weight ratio and great design flexibility. The modern steel industry has been making in-roads to residential construction and material price reductions in the 1960 s made it a more affordable option.
Q:Are the shafts on my clubs graphite or steel....?
Hold one club in each hand and hit them together like swords fighting, putting the impact point about midway down each shaft, and listen to the sound. If it's more of a clank sound, it's steel, and more of a click sound, it's graphite.
Q:Buy a steel building!!!!?
A steel storage garage?? Proper ground preparation---steady level ground--and lots of friends to help erect it.
Q:Welding Stainless Steel?
Yes you can use regular welding rods for stainless steel. But you will not have the properties of the stainless. The weld joint will have a different color than the stainless if you grind/grain/finish the weld. It could also rust. The joint could be weaker. It is best to use a rod that comes as close to the base metal stainless as possible. (30 years welding - certified)
Q:List out the Industrial application of Eutectoid Steel.?
Eutectic steel is used to produce pearlite, bainite, spheroidite and martensite steels. Those steels vary in strength, hardness and ductility. One uses martensite steel for example in razor blade manufacturing. Of course there is no end to the various uses of these steels.
Q:Are steel casings reloadable?
Let me break it down for you. 1) There are two kinds of priming in current use these days -- you cannot tell from the outside which primer it is...only by looking inside the casing. If the casing has a single center primer hole, it is Boxer primed. If the casing has multiple primer holes, none of which is center, it is Berdan primed. Berdan and Boxer are the names of men who designed the priming systems.
Q:What is the density of steel?
Density Of Steel
Q:Steel question?
Strength of metals is normally measured by the tensile strength as the main measure although this is not the only property as hardness is another big factor. Basically, iron is soft and steel is hard. Plain iron is stretchy and does not corrode quickly, whereas steel is much stiffer and corrodes more quickly. The tensile strength of cold worked iron is about half that of an average steel, likewise the hardness is about half that of steel too. Pure iron, which is rarely used, is even weaker and softer again and a bit more like softer materials like copper and aluminium. Where confusion comes in is that there is another iron - Cast Iron - which is totally different to both iron and steel. Cast iron is very hard and tough but incredibly brittle so its properties are very different.
