 Prepainted Galvalume Rolled Coil for Construction roof

Description of Prepainted Galvalume Rolled Coil
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 Prepainted Galvalume Rolled Coil

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:Steel Wool + 9V Battery Question...?
Steel Wool 9v Battery
Q:Does anyone know anything about Kodiak Steel Homes?
Steel framing replaces all the wood making the house stronger and resistant to termites. Costs about $2,000 more per house and there is a lack of trained framers in most cities. Never heard of Kodiak brand. Do you know a city where they are located?
Q:Middle name for Steel?
Steel Keith Tompkins Steel Caleb Tompkins Steel Jude Tompkins Steel Lukas Tompkins Steel Ezekiel Tompkins Steel Cole Tompkins Steel Colin Tompkins Steel Lars Tompkins
Q:whats the benifits of using steel material for fasteners?
Relatively cheap, strong, and non-toxic. For Carbon Steel alloys rust and corrosion are problems. For stainless alloys, cost becomes the problem [and corrosion is not eliminated]
Q:Cold steel katana?
Save your money and by a wooden boken. Train with a well balanced wooden one. It is how the great Japanese master started their training. Steel swords are good for display. and perhaps if you become relay good and want to feel the heft and practice cutting straw men and bamboo stalks than invest some money in the real deal for a few hundred $$ at the least.
Q:can jb weld fix steel applications?
Not a chance. Stresses that are strong enough to crack solid steel would snap JB weld like a matchstick! JB is NOT a substitute for actual welding. Steel is more than 20 times stronger; or in other words, JB is 20 times weaker than the steel in your chair. JB is good for applications where the parts to be joined aren't constantly going to be under stress. For wood or plastics it works OK, for steel, not so much. Your best bet is to take the chair to a professional welding shop. If they want to charge you more than $15-$20; go somewhere else, they could weld that in less than a minute.
Q:why does steel rust?????????????
Steel is made adding carbon to iron.The iron in steel reacts with oxygen in the air, producing ferric oxide(Rust).
Q:i have guestion a bout steel?
Steel is an alloy. An alloy is a mixture of metals melted together, a solid solution. There are many recipes for steel depending on what the use is. Steel is an alloy of iron and another metal .Low carbon steel has less than 0.3% carbon, carbon steel is 0.3 to 0.6% carbon Low carbon steels generally contain less than 0.25% carbon and cannot be strengthened by heat-treating (strengthening can only be accomplished through cold working). The low carbon material is relatively soft and weak, but has outstanding ductility and toughness. In addition, it is machineable, weld-able, and is relatively inexpensive to produce. Carbon steel, also called plain carbon steel, is steel where the main alloying constituent is carbon. The American Iron and Steel Institute (AISI) defines carbon steel as: Steel is considered to be carbon steel when no minimum content is specified or required for chromium, cobalt, columbium, molybdenum, nickel, titanium, tungsten, vanadium or zirconium, or any other element to be added to obtain a desired alloying effect; when the specified minimum for copper does not exceed 0.40 percent; or when the maximum content specified for any of the following elements does not exceed the percentages noted: manganese 1.65, silicon 0.60, copper 0.60.
Q:Can you give me the general working and description of a steel cooling bed?
In the USA, a steel cooling bed is called a run-out table. It consists of a series of steel rolls. Each roll may be individually driven by an electric motor. DC motors are often used with parallel armatures connected to a common armature voltage control speed control unit. The roll speed is controlled to match the speed of the incoming sheet of steel so that the steel does not slide or skid on the surface of the rolls. Field trim resistors help to assure that the speed and torque of rolls is matched. A centering mechanism may be used to keep the steel in the center of the table. Water may be sprayed from the top and bottom to aid cooling. After an initial run out table, the strip of steel may be cut on-the-fly into individual sheets which pass to another table that is running slightly faster to separate the sheets. Alternatively, the steel may be coiled at the end of the table.
Q:stainless steel not so stainless?
Use oven cleaner. It will take off the burnt on stuff just like it does in the oven. Spray it on, put the cover on the pot and let it sit for a while. If the problem is on the outside, do the same but put the whole thing in a garbage bag to control the fumes. Wash the pot like you would normally to get the oven cleaner off. You will want to wear gloves too. Oven cleaner is very caustic. By the time you realize you are being burned by it, it's too late. The oven cleaner should do nothing to the finish of the stainless.
