 Prepainted Aluminum Zinc Rolled Coil for Construction roof

Description of Prepainted Aluminum Zinc Rolled Coil for Construction 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 Prepainted Aluminum Zinc Rolled Coil for Construction 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:steel or aluminum? I'm looking to try a steel mtb for first time?
I've ridden steel, alum, Ti and carbon. I like 'em all. It all depends of craftsmanship and design IMHO. Really, a light steel frame is only about 1 to 1.5 lbs heavier than other super light frames. Steel has a rep for being heavy and most of that comes from being a heavier duty frame and being spec'ed with heavier parts. With that being said I have 2 alum and 1 carbon framed bikes now. I owned several steel bikes in my day, loved 'em too. I like light and if you're a weight weenie too you may not want a heavier bike regardless of material. The Stumpjumper is a sweet light bike. If the Grizzly is up to your specs give it a go. Thats how you experience life. Try something different. You'll like the feel of steel, as of the bike? Only you will know if you like it or not.
Q:why use brass sell casings? why not steel?
Brass has a natural lubricity that makes easier to extract after firing. It also can easily be resized for reloading. Steel offers neither of these properties. It cannot be reloaded so is good for only one single use. Brass has simply shown, by virtue of its metallic characteristics, to be the best choice for manufacturing cartridges.
Q:what type of steel is used to make rail tracks?
Well i guess they have to ( engineers ) take into account stuff like tensile stress and crap and then also the amount by which it contracts and expands during extremme tempertures if i were you put this question under the engineering section. It might lead to a right on the nail answer and also there ought to be a log book which gives us like you know the best steel for railroad maufacture. Architectural engineers or construction engineers are always goin around with books bookworms to be more precise. haha anyways best of luck mate.
Q:will a stainless steel gun rust?
Stainless steel does not rust. But your Stainless Barrel is not true stainless steel. True stainless steel is a mix of steel and chrome, and the chrome has a certaion percentage of the overal weight.. But a Stainless barrel does not contain enough chrome to be true stainless, so it can rust.
Q:can any you boil steel?
hahah umm ya u could boil steel but prob not at your house hahah and the boiling point of a medium carbon steel to be around 3000K
Q:How much can the metal steel lift?
much too vague. Need the shape and thickness of the steel, where it is supported, and where the load is placed.
Q:what is the elastic limit of steel in Nm^2?
Elastic Limit Of Steel
Q:what is the difference between METAL and STEEL?
A metal is a chemical element that is a good conductor of both electricity and heat and forms cations and ionic bonds with non-metals. Steel is a compound made from Iron and Carbon. Ratios of 0.2% and 2.1% by weight (information by wikipedia)
Q:Which bunkbed is more sturdy: Wood or Metal/Steel?
Metal/Steel, tighten it down and put some washers in between the steel and the screw so it creates a tight fit and movement wont affect the screw directly.
Q:Do steel guns burn when exposed to flames/ extreme heat?
Yes they melt and rather easily. Guns are made by melting steel and many police departments destroy confiscated guns by melting them.
