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:Question about building buildings with a steel frame.?
Most of the parts are cut, welded, and fabricated indoors in a welding shop at another location. Then they're trucked to the site and simply need to be bolted together. This is made possible through the use of computer aided design and modeling programs, so that parts can be made to fit almost presciently in the field. They buy the steel from steel companies. I couldn't tell you exactly where it comes from, you'd have to ask the contractors themselves.
Q:Liquid stainless steel paint?
I am also considering buying Thomas Liquid Steel, but have not used it or seen it used before. I did call a store that sells this product and they said they saw the mfg demo the product at a trade show. The store rep told me that the results were absolutely amazing. I think I will buy the medium kit direct from the mfg for $129 and give it a test run first on something other than my kitchen appliances.
Q:How durable is stainless steel jewelry?
The bigger question is how will the watch movement hold up over time? If you have a lifetime warranty, don't worry about it they will probably offer a replacement if it gets too expensive to repair. Most men I know have given up watches except for the wrist jewelry look when going out, as you say. Because everyone carries a cellphone and doesn't actually need a wacth any more.
Q:Steel phases question!?
hey from what i learned in uni last sem, steel is originally ferrite form at first at room conditions. it will undergo poly morphic transformation to become FCC structure austenite form at 912 degree celcius. under conditions, it can become pearlite (which is a combination of ferrite and cementite) or bainitie( a finer form of pearlite). queching conditions to room temperature will form martensite which is the strongest but brittle steel form. tempered cementite is formed when we quench it and then raise temperatures before sir cooling. hope it helps, pls vote me best answer is i deserve it. thanks
Q:Quality of Cold Steel Recon 1 (folding knife)?
I think that 440 stainless steel is pretty good. I like Gerber,Kershaw knives in 440 stainless steel. D2 steel is also as good or better than 440. I am not sure of Taiwan/China steel.
Q:Quick ... Does fire burn steel?
Fire doesn't burn steel, fire is the catalyst for steel to react with oxygen and burn though technically it's oxidizing. An intense flame like that found in an Oxy-Acetylene torch will bring the steel to melting point, then the operator would toggle a lever on the torch blasting pure oxygen into the steel causing it to oxidize and fall away from the workpiece. The afore mentioned steel wool exercise illustrates the principle on metal so thin that the heat provided by a candle allows for oxidization with the oxygen present in the atmosphere.
Q:How much is obselete steel worth when sold as scrap?

Q:What is cold steel ?!?
Cold steel was an expression originally used to signify a sword. From feeling the cold of the blade as it entered the body.
Q:Safety of steel-capped boots?
Hey Bunny:) Glad you asked! I know of no one ,at all,that thinks steel toes are better than good reflexes and the ability to move faster! Wellies give flex,Sport shoes give speed, Jods(Paddocks) are the work boot of choice..and if there is one thing we know about horses, nothing happens in slo-mo! There is a fiberglass toe protector a person could use.. I guess..not this person though. Added to the factor that they have that bumpy sole not suited for riding, and a bad heel, and are just plain too heavy. And ankles! nothing special there. My flatmate(roomie) is an Equine reproduction Vet and a Polo Player, and no-one there has anything but jods and wellies. No clunky boots please:) Come to think of it, its been years since Ive mashed a foolish toe..and that takes into account trailering vetting and young-stock work....Yes I vote for movement over safety ** there are no horse-goods for sale with toe caps ** Three cheers for mobility bunny! (and wellies disinfect real nice too)
Q:What are steel cut oats?
It does NOT look or cook like oatmeal but is made from the same grain. It takes much longer to cook since it is a whole grain, and tastes very good by the way. If you hate the slimy feel of oatmeal, this is the one to try, with all the same nutritional goodness of oatmeal. You can find it in most grocery stores in the hot cereal aisle. EDIT: you are right Mnt. Camp, steel cut is better that the regular oatmeal.
