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: I know that they have steel shot in smaller sized pellets....say, number 4 shot. I guess it's for waterfowl, etc.Do they make steel buckshot? If not, why not? Would the pellets be too heavy? Wouldn't they have excellent penetration ability?
- I know of no one who makes steel buckshot. Probably for several reasons. Steel is much lighter than lead. Penetration depends on energy, which is the weight of the pellet vs. the velocity of the pellet, equated into ft.lbs. Steel pellets have to travel much faster to achieve the same energy as a lead pellet. Steel, being lighter, would lose energy much faster downrange. The weight difference would be like teeing up a golf ball, and striking it with a club, and teeing up a ping pong ball and striking it with a club. The distance in flight would be obvious. Steel also, is much harder than lead, and would be hard on the barrel, and choke. It also would not deform, which would cause ricochets. Steel shot was a handicap for waterfowler's when the USFWS made non toxic shot mandatory. Waterfowl are bottom feeders, and they were eating the spent lead pellets, and dying from lead poisoning. Steel shot cut the effective range of a shotgun from 45 yards to around 35, and resulted in many cripples and lost birds. Environmetal, makes a T size shot which is .20 caliber, and is called Hevi-shot. Lead is heavier than steel, and Hevi-shot is heavier than lead. At the same velocity, you have 12 to 15% more energy than lead. and probably 20% better than steel....Hope this helps
- Q: rust is not a issue. i was looking a D2 steel but heard story's of it chipping and breaking
- Ok, lets define what is Damascus steel. The modern Damascus is basically any steel that shows a pattern. Patterns are accomplished by 1. manipulating the crystal structure or 2. by combining 2 or more different alloys together. The blade you are looking at is referred to as a pattern welded blade. Damascus is only as strong as it's base components + heat treat and design. The strongest will be obtained by combining high carbon and low carbon steels. I do this by using steel cable. The patterns aren't real bold but are interesting none the less. To break it you must brake the hard steel and tear through the soft iron. The laminated stuff works the same way. For greater edge holding I use all high carbon, varying alloy content from simple carbon to chromium/nickle alloys. These are what you normally find in pattern welded blades. A fine pattern that has many lamination's crossing the edge will offer the best edge holding. Properly done one can get the DCE or damascus cutting effect where the soft layers wear away faster than the hard layers almost making the blade self sharpening. Is that blade good? Buy it if you like it, it won't compare to a well made hand forged blade but is much cheaper. sorry for the overload.

- Q: What are the different grades of steel coils?
- There are various grades of steel coils available, including low carbon steel, medium carbon steel, high carbon steel, stainless steel, and galvanized steel coils. Each grade has specific properties and applications, making them suitable for different industries and purposes.
- Q: Is there any noticable or perceived difference between smoking out of a pipe with a brass screen and a stainless steel screen?
- Its not a good idea to make the whole thing of metal. Metal is a good conductor of heat and its bound to get too hot for you lips during sustained use. Thats assuming your going to smoke tobacco with it. If you plan on smoking small hits of a particular substance then it may be alright. Mind you pipes are poor choice for this kind of smoking. So sticking with the tobacco pipe I would make it out of wood or talc not metal.
- Q: what do you think about producebility of low density steel? for example: can density of 1020 steel (or ony others) be decreased without any loss of other properties.
- If a material has a lower density than steel, then it isn't steel.
