Structure of Prepainted Rolled steel Coil for Construction Roofing

 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:Edward Humphrey wants to know... Can I use steel roofing on an older house?
steel roofing is a very logical option when considering replacing a residential roof. Keep in mind that in addition to the cost of the actual metal roofing panel, most likely, in order to qualify for the warranties associated with these products, you must also use their accessories and adhere strictly to their installation instructions. If you have a very cut up house, lots of dormers and valleys, etc, the costs to waterproof these areas before installing can get to be costly, but as far as a straight forward reroof over existing substrate, costs are very competitive. As much as I see a lot recommend going over existing shingles, I prefer to strip the existing shingles, and check the sheathing, before waterproofing and roof installation.
Q:Prefabricated Steel Buildings.......!?
It really depends upon the environment and the construction techniques used. Steel that is painted or coated will without maintenance eventually rust. I would expect this tendency to be exacerbated in a humid or shore environment. Heat may tend to cook a steel house and the structure does not add much thermal mass. Construction techniques tend to be fairly quick a part of the construction is essentially prefabricated. Work done in a factory will almost always be cheaper than work done in the field, all things being equal. Concrete can be fairly hi tech with lots of equipment or as seen in many parts of the world fairly low tech with lots of laborers. It is easy to change the characteristics of concrete depending upon how it is mixed, reinforced, and treated during the curing process. Because it is applied in a relatively fluid state it can flow around obstructions like bedrock and be formed up into interesting shapes. A concrete structure can be cooler as it provides thermal mass, and a heat sink. It's resulting rigidity may make it more subject to earthquakes than steel. We do really need to be smarter in constructing our homes to make them fit the land and not only the general environment but our particular micro environment.
Q:Rusted steel straps on deck posts?
If these steel straps are rusting through and on their last legs, a coat of paint is going to be cosmetic at best. Replace these straps with new ones. The originals were either very poorly galvanized, or you live someplace with a very corrosive environment. In any event, paint can't save this sort of thing. Steel brackets serve a real purpose, and after they're weakened, they can't do that anymore. How would your home hold up in an earthquake, for example? What you're proposing doesn't sound safe.
Q:Fire resistant steel?
In the fire protection world, we do not consider steel fire resistant. Of course it doesn't burn under ordinary conditions, but it lose strength as it is heated. As has been mentioned, there are coatings which insulate steel to enable it to withstand high ambient temperatures for a long time. Construction using this method is called fire resistive construction.
Q:What grade of steel is best suited for use on ships. Specifically trawlers?
How big is your trawler going to be and what use, The ones you see off the Alaska Coast or a Gulf Coast Shrimper? My preference in today's economy would not make sense and that is Aluminum.....not steel at all, maybe even Fiberglass, but $$$$ talk so Steel is cheaper, but you need to know what you are doing. The designer of the hull should have specified the right /preferred grade. It today's world there are many more choices available. You use a mild steel, most often grade A or B, but some applications call for grade D. Check your blue prints and list of materials. Edit. Ok I understand. There are 2 ways to go. One is use a relatively cheep steel and use higher cost epoxy primers and paint, often requiring special surface preparation just before priming, or two, using a much higher cost steel with more chrome and nickel in it. Grades that begin with #3xxx These are weldable with rods that are available, and can be welded directly to mild steels. However these are 3X the cost. If your a Shrimper, I'm guessing gulf coast. I worked with several boat yards in the 70's installing spray urethane foam for insulating there holes. So I've been around lots of small yards from Florida to Texas. I'd call the nearest steel warehouse and ask what they would recommend. You might find what you want at a scrap yard. I've lucked out several times picking up 1/4 plate scrap$ and I'd bet the scrapyard guy would know just what you need. I know there are places to get what you need in Mobile and New Orleans. Good luck!
Q:Major disadvantage of hardened steel?
a disadvantage is the fact that the cold forming capability of this steel
Q:Science help!?! steel wool experiment?
steel wool = iron fibers and rusts easily in air iron + Oxygen BUT the blue soap protects the iron at first. that needs to be cleaned off. damp surfaces speed the rusting but compeletly underwater there is not much O2, ther eis some temperature has an effect. the rusting depends ofn the area of the fibers which does NOT change when you cut th epad in smaller pieces. a good beginners experiment In old times thye thought the rusted material would lose weight becasuse it was not solid iron any more careful experiments showed it gained weight and lead to and understanding of chemistry

Q:knife made of 304 stainless steel?
just because something is made out of 304 stainless steel does not make it tougher than carbon steel. Stainless steel includes other elements such as chromium. 304 stainless cannot be hardened by heat treatment.
