Structure of RAL Scale Z35 Prepainted Rolled Steel Coil for Construction Roofing

  RAL Scale Z35 Prepainted Rolled Steel Coil for Construction Roofing

Description of RAL Scale Z35 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 RAL Scale Z35 Prepainted Rolled Steel Coil for Construction Roofing

1.Corrosion resistance: It mainly depends on the zinc protection. When the zinc being worn,

2. Heat resistance: 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.

Q:A roll of 1 meters wide color steel roll about how many tons?
In general, between 3.5 and 5 tons. Our company uses 0.17*1000 white color steel roll. The weight is usually around 4.5 tons. Different manufacturers will have different sealing rolls.
Q:Why was there molten steel at Ground Zero?
that's just it: there wasn't very much molten steel for the very reason you point out. Jet fuel burns at 800° to 1500°F. This is not hot enough to melt structural steel. However, engineers say that for the World Trade Center towers to collapse, their steel frames didn't need to melt, they just had to lose some of their structural strength. Steel will lose about half its strength at 1,200 degrees F. The steel will also become distorted when heat is not a uniform temperature. after the collapse, a LOT of folks took a look at the remains. the result was the conclusion that the fire caused the central core of the building to weaken. When the floors collapsed one on top of the other, the weight was too much for the weaked core to bear, causing the result we are all familiar with. hope this helps
Q:Arc welding: DC needed for stainless steel?
Arc or stick welding is not ideal for stainless steel. It is advisable to use MIG or TIG welding instead, with argon shield gas. I would only advise manual arc welding as a last resort, or for field repairs. Expect corrosion issues, and issues with excessive oxidation and porosity in your stainless welds. Manual arc welding is a dirty process and simply does not protect the weld puddle well enough from oxidation and carbon pickup, which are especially damaging in sensitive stainless alloys. As to whether to use AC or DC for stick welding, you should consult the instructions found on the box of electrodes. If polarity and current recommendations cannot be found, then you should contact the manufacturer and get it in writing. You should probably not make welding decisions based on advice from a sales representative. Firstly is is not documented. Secondly, sales representatives are not legally liable for damages caused by weld failures, YOU are.
Q:whats the benifits of using steel material for fasteners?
Relatively cheap, strong, and non-toxic. For Carbon Steel alloys rust and corrosion are problems. For stainless alloys, cost becomes the problem [and corrosion is not eliminated]
Q:what metals are more dense than steel?
Stainless steel 7480 -8000 kg/m^3 Brass 8100 -8250 Cobalt - 8746 Copper 8930 Gold 19320 Lead 11340 Mercury 13593 Molybdenum 10188 Nickel 8800 Platinum 21400 Plutonium 19800 Silver 10490 Tungsten 19600 Uranium 18900
Q:Question about steel studs.?
Steel studs are mainly for commercial applications on non bearing walls. 100 studs, must be one big assed bathroom. Do yourself a favor and install a pressure treated bottom plate, even if you use steel studs.
Q:BMX Help, High Tensile steel VS chromo steel for cruising?
High tensile steel could mean almost anything. SAE 4130 Chrome-Moly steel is the de-facto standard for steel bikes frames. High tensile steel could actually mean the same thing since chrome-moly is classified as high strength steel. The strength of the frame depends as much on the quality of the welds and on the size/thickness of the tubing as much as anything else. I'd say what kind of steel you use makes only a minor difference. One reason you want to buy bikes from reputable name-brand companies is they tend to have strict quality controls, this is particularly important when it comes to welds. Welds are always the weakest part of any bike frame, don't let anyone tell you different. 99% of the time if something in the frame breaks, it'll be at the welds. hope this helps.
Q:white gold engagement ring with stainless steel wedding band?
I am a manufacturing Jeweller. Yes there is a difference in the colour between Stainless Steel and White Gold. The wear characteristics are also different so you will notice a difference in the wearing of the rings. I would doubt that tiffany's would make stainless steel rings. Most likely they are stocking Titanium rings, which look like stainless steel. But the same problems of colour and wear exist for that metal as well. Your best bet is to get a white gold ring , and check out other manufacturing jewellers first because you will not be getting an investment from Tiffany's. Their profit margin is that high you would get a nosebleed. the scrap value of a 5 gram 18ct white gold wedder is $120. anything over that is the profit margin of the jeweller. for a plain wedder I charge $20 per gram to make plus the gold so that would be a total cost of $220 for a 5 gram ring and $440 for a 10 gram ring. I hope this is good information to you Also you must ask what type of 18ct white gold are you getting? there is; Platinum alloy Palladium alloy Irridium alloy Nickel Zinc alloy or a combination of any or all of the above with prices accordingly

Q:s1 tool steel i need info?
s1 tool steels (also calles high-speed steels) are used in the manufacture of cutting tools such as drills, reamers, taps, milling cutters, and lathe cutting tools. They are made from different types of steels. They are generally used in machine shops for making holes. .
