 Prepainted Galvalume Rolled Coil for Construction Roof

Description of Prepainted Galvalume Rolled Coil
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 Galvalume Rolled Coil

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:What is Light gauge steel? is it same with light weight steel?
as a welder i can answere this. wel i think i can after 2 years of classes. so...light guage steel usually referes to the THICKNESS of the metal. also known as SHEET METAL. the only diffrences between light guage and roof truss is that a truss will be thicker metal ex- an i-beam for a structure is usually 1/2inch or 3/8 for smaller buildings. also there is no such thing as light weight steel. steel is steel the only thing that determins its weight is its size/thickness aluminum is a whole nother ballgame. ever see a pound of aluminum vs. a pound of steel? aluminum can be 1/2 or less the weight of steel. but its tensile strength suffers EX. say steel will snap at 70,000 pounds, aluminum will snap at 40,000 pounds, if it even snaps that is! it just tends to bend like rubber. aluminum is handy for many things because it will not rust.
Q:silver soldering stainless steel?
You can buy it on Ebay . The flux cleans the surface so the solder will stick . Check with a welding supply to see if this process will work on stainless.
Q:Steel toe boots safe?
Go to Discovery channel and look up Mythbusters episode on steel toed boots. It will surprise you what they can take, even with dropped items. They could get some damage, but never a severance.
Q:Stainless steel pots?
The difference in stainless steel cookware is the amount of different metals used when making them. 18-10 is the best combination. I have Tramontina SS pots and pans and love them. Nice heavy bottoms that evenly heat. Getting used to cooking with stainless is a bit difficult. You need to start with high heat and then turn it down when you add ingredients. This assists in food not sticking.
Q:Steel String for Classical?
If the guitar was designed for nylon strings, then don't put steel strings on it!
Q:Is boron steel harder?
Boron is classified as a Metalloid element and is located in Groups 13, 14,15, 16 and 17 of the Periodic Table. An element classified as a Metalloid has properties of both metals and non-metals. Some are semi-conductors and can carry an electrical charge making them useful in calculators and computers.
Q:how to forge damascus steel?
hand made folding knife English tip, blade of Damascus metallic sort Rose, 2,5mm thickness, no liners, teja spring embellished by using metallic report and billet surrounded of chrome metallic. A Damascus blade knife is characterised by using a wavy, mottled visual allure on the blade that’s led to by using the approach used to shape the metallic. the technique of transforming into Damascus metallic is derived from a centuries-previous forging technique used to create blades that grew to become very just about mythical of their attractiveness for power and sharpness it exchange into reported a Damascus knife ought to shrink with the aid of a rifle barrel to boot as with the aid of a hair falling on the blade.
Q:mechanical behaviour data for recycled steel?
Most recycled steel is blended with new steel at the steel mill. Scrap steel that is reused directly doesn't change it properties because it has been used. That is unless it has been in certain environments such as ones with hydrogen, hydrogen sulfide etc. Then the steel can become brittle. You might look for information on the National Association of Corrosion Engineers (NACE). They have lots of information on metals and what causes problems.
Q:Steel Estimating Question?
That is a little tough to answer given the details. I will try to answer it as best I can. You can send me a message if you need further help and I can get some more details from you. If it is a 6 million dollar project, that is about $428/sf - (6 million divided by 14,000 sf). $428 is a little bit higher end then say, just a Walmart which is a block and steel box. Assuming you have a concrete slab on the first floor, metal deck on the second floor, with steel beams and open web joists framing, steel columns and steel roof framing with a metal deck roof.... you could be approx 10-15% of the total 6 million. Now, this would include the structural steel, not light gauge steel framing for walls. It sounds like you are looking for structural steel, not metal stud framing. Hopefully this helps, I can check back to this thread later to see if you've had to add any more details.
Q:Should I keep my steel cents as an investment?
The steel in steel cents is the same as the steel in soup cans you throw out all the time. There is no sense in holding steel cents for their value as scrap. There are way too many steel cents around for them to ever have much numismatic value.
