 prepainted Rolled Steel Coil for Construction Roofing Constrution

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:where can you buy steel from?
This okorder.com/... Most towns have a steel supply house/ business, check your yellow pages. Also check with local welding and machine shops. They can give you ideas and or their suppliers. They often have bits and pieces that you might buy, instead of ordering a full sheet of material. Wingman
Q:Carbon Steel strength grading?
Yes. Most high quality knives are made of carbon steel versus say stainless steel. High strength carbon steel holds an edge well and is strong.
Q:What is extruded steel?
Extruded steel is only the steel being run through a die when it is heated, it usually reduces the size of the grain of the steel itself, enhancing toughness. Realistically though, in a handgun, it doesn't matter if the frame is cast or forged, both types will hold up to any amount of abuse, unless you use it as a sledgehammer, and are splitting stones with it, then the forged frame would win. 4140 is more than adequate for a slide/frame. Hell, even mild steel would be adequate as long as you don't mind some dings and scratches, and again, don't use it as a sledgehammer...
Q:British Steel Logo?
Bristish Steel...ROCKS!!! Ebay is a good suggestion but if its something custom like that you could always bring in a drawing or picture to a jeweler and they can source it for you ;) I did something similar and the jeweler actually made it custom for me.... just a suggestion :) Good Luck!
Q:Will this steel rust?
Stainless steel is not rust proof. it's just rust resistant. It will rust. It just takes much longer to do so... So, yes, I'd dry it well after use, and even consider wiping it with a cloth containing a very lite coating of oil.
Q:Does anyone know about steel framed houses?
the building I work in is steel framed, no humidity problems. I can't believe that steel frame anything causes humidity problems. I would ask for an explanation from whom ever told you this. One thing is cell phones, radios etc. have bad reception due to all the interference.
Q:Are steel toed hiking boots worth buying?
Steel Toe Hiking Boots
Q:how many persent of manganese in all types of carbon steel?
Not more than 1.65 % of manganese in carbon steel. *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 *AISI 1040 is a carbon steel which is having a 0.60-0.90 % of manganese.
Q:Steel Barns..........?
Steel barns in the USA is the going fad; they are both strong and economical; and some companies offer DIY kits
Q:I need flint and steel how do i get it?
no common flint and steel in the house === you need to buy a Boy Scout - flint and steel fire starter kit === or a BIC lighter ... the other thing is a small jar filled with water [[ capped and water level near the top.]] hold the water-jar over some
