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:making holes is iron and steel?
It really depends. If you are drilling iron, I assume you are talking about cast irons and there are many different types, some are easier to drill (and machine) than others. For steels, there are many many different types of steels which can have a huge range of physical properties. In fact, your drill bits are almost certainly made of some type of steel alloy. If your drill bit has the same hardness as the steel you are trying to drill, it will be difficult to drill. If the steel is harder than the drill bit, you won't make a hole, you'll just break your drill bit into smaller pieces. There are drill bits that use carbide inserts or diamond composite inserts and these will drill through steel. You can do a quick check. Take a drill bit and, just by hand, see if it scratches the steel. If it does, then the drill bit is harder than the steel and you can probably drill a hole. If you have trouble drilling holes, consult a machinist. There are many factors which influence how well you can drill holes including use of cutting oils/lubricants, cutting speed, pressure, rake angle, etc.
Q:Why not use stainless steel to make coins?
Stainless steel has been used by some countries to make coins, but it's not an ideal metal. When a coin is struck, a die comes down and strikes the blank with many tons of force (the blank is also sitting on top of another die--one has the image on the obverse (front) of the coin, while the other die has the image of the reverse of the coin). When the die strikes the blank, the force causes the metal in the blank to flow into the recesses of the die. The problem with stainless steel is that it doesn't want to flow into the die. To get an image, either the relief (how high the raised portion of the design will be) has to be very low, and the coin has to have a simple design, or they have to greatly increase the pressure of the strike. This slows the coining press down, and greatly shortens the life of the dies.
Q:Polishing stainless steel (revolver)?
Stainless Revolver
Q:Is a knife with damascus steel better than one with regular steel? or what about high carbon?
This Site Might Help You. RE: Is a knife with damascus steel better than one with regular steel? or what about high carbon? What would be a better knife one with damascus steel or one without? Why is damascus steel so special other than the look? And why do some people say high carbon steel is better than regular? mainly though I want to know about the damascus. Thanks, max points to best answer.
Q:Question about the strength if steel?
There are many types of steel some very rigid, while you can have steel that is very flexible. The type of katana: steel is for Samurai swords
Q:How strong is 440 steel on a katana?
That is intended for display only. In other words it is useless for any other purpose. Stainless steel is only good for short knives. As it does not hold an edge and is not very strong.
Q:What is the accuracy of steel tape inspection?
For example, you measure the length of a steel tape by 12.5 millimeters, 12 of which can be measured on a steel tape measure, and 0.5 you read. So the accuracy is millimeters.
Q:What is the best butcher's steel?
Butcher Steel
Q:what is difference between high carbon steel blade for katana swords?
The guy below me obviously has no idea WTF he's talking about. It does NOT have anything to do with the edge angle at which the blade is sharpened. It does NOT have to do with heat treating. Both of these things are important, but they won't determine the type of steel. I'll try to help. 1095 is one of the best performing steels, against carbon steel or stainless steel, in the world. It's incredibly hard, holds its edge well and comes to a beautiful edge when sharpened correctly. As you know though, carbon steels need to be properly maintained to avoid rust/corrosion. Out of the steels you listed I'll give a brief summary of each steel... -1095 (Great all around steel, but is brittle by comparison to the others. This doesn't mean it will chip easily, but the other steels can take more of a beating. That being said, this is going to take a nicer edge, and hold it longer.) -1080 (A little bit more flexible and less liable to chip than 1095. A good compromise between edge retention/quality and ruggedness. -1065 (Commonly used in machetes and other heavy duty bush tools. Takes a decent utility edge and is highly unlikely to chip) -1060 1045 (Both extremely flexible and soft in comparison to 1095. Unlikely to chip, but it takes a crude edge. This edge will cut, but not like 1095 will.) Go with 1095. My favorite knife I own is in 1095 and serves me well everytime I head off into the woods. Keep some Rem-Oil on that bad boy though.
Q:What's the length of a coil of cold rolled steel? Is there a standard?
In 2.0*1000*C calculations, it is assumed that the formula for the length of 5T in this volume is 5000/ (2.0*1000*1000*7.93) = the total number of meters. First, the weight of one meter is calculated by dividing the total weight by the single weight, that is, the theoretical length of the volume
