Structure of RAL Scale Prepainted Rolled Steel Coil for Construction Roof

  RAL Scale Prepainted Rolled Steel Coil for Construction Roof

Description of RAL Scale Prepainted Rolled Steel Coil for Construction Roof
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 Prepainted Rolled Steel Coil for Construction Roofg

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:Best affordable steel combat knife?
Sorry, probably aint gonna happen in that $ range. How big of a blade will effect the steel selection. For instance I have one I forged from 52100, a most excellent steel better suited for 5-6 blades. For larger blades either 5160 or L-6 can make an indestructable blade. For 5 and under D-2 is about as fine a steel as you can get. No blade made from these will come cheap, L-6 is only available from custom makers. Save up your money, expect to pay 100 - 200 for a well made blade. You pay cheap prices you get cheap workmanship.
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
Q:Why is iron stronger than steel?
This Site Might Help You. RE: Why is iron stronger than steel? I was watching a documentary on the samurai vs the European knight. It said that the when Japan was being invaded by the (cant remember) they needed a new weapon. The enemies armor made iron swords useless. While steel swords broke when in combat. So to combat this the Japanese made a hybrid...
Q:How to temper steel? ?
Heat treating easy, HA! It is the most critical part of bladesmithing. Done wrong and all those hours of work go up in smoke (or a snap of the steel). You'll need a bucket of oil, preferably one that is deep enough to go in point first. If not you'll have to go in edge first, not recommended on a double edged blade, ok for single edge. You'll need to build a charcoal fire long enough for the blade. You will need to blow air under the fire to get it hot enough, the challenge is getting the heat even. You get the fire going and established, put the blade in turning it back and forth (if you keep turning it in the same direction when it heats up you could work a twist in it). When it starts turning red pull it out and touch it with a magnet, if the magnet sticks put it back. Keep heating and repeating until the magnet no longer sticks. Heat a little more, then quench rapidly point first. Don't let the blade lean to one side as warpage will occur. When it cools enough to touch, check with a file. If the doesn't file cut then you've properly hardened the steel and it's ready for temper. Now comes the really hard part. Grind the scale off carefully,preferably with a side grinder with a flap wheel. I've had hard wheel break freshly hardened blades. After cleaning you'll need to put it in an oven (preferred) or use a torch and carefully heat the blade. Watch the temper colors (oven temp 500-550F) or with the torch as the steel turns colors blue to purple for a double edged weapon. Any warpage that occurs needs to be worked out at temping temp.
Q:dangers of the steel factories?
Same as other steel plants, getting crushed by falling steel, getting burned by hot metal etc
Q:Urine dulls too shiny stainless steel?
Stainless steel will rust under proper conditions. I live on a boat on salt water, trust me. If the urine works it won't be prone to rusting any more than before. It's not the shine that inhibits rusting with stainless steel, it the % of carbon in the steel, compared to regular steel. IF the urine works it's because it is acidic (a mild acid). Wash it with a small brush and some baking soda to neutralize the acid when your done. A much stronger acid would be swimming pool acid. (Muriatic acid) but be careful you might test a spot with a Q tip on the back. If you try Muriatic acid it would take seconds.Then wash in baking soda water to remove all acid.. SS
Q:Recycled Stainless Steel market prices.?
Steel is at an all time high of $3.99 per hundred pounds..Stainless will sell for more....I haulled a pickup truck full 3 days ago and got over a 100 bucks for junk I had laying around the yard.
Q:Is clorox safe to clean stainless steel?
Thanks to Yahoo about a year ago, I have the perfect answer for you. Below is the recipe for Tub and Tile Cleaner that I copied off Yahoo and I would never go back to using other cleaners again. Ingredients: 2/3 Cup Baking Soda 1/2 Cup Liquid Soap such as dish soap ( I use Palmolive Anti-bacterial ) 1/2 Cup Water 2 Tablespoons White Vinegar Instructions: Whisk together baking soda, soap, and water until smooth and creamy. Add vinegar and let stand a few minutes to foam. Combine all ingredients until thoroughly blended. Store in an airtight container such as one that margarine comes in. Stir prior to using and it doesn't take very much of it either. Use for tubs, toilets, sinks, counter tops extra. This is an excellent cleaner and environmentally safe. Does a great job and your stainless steel sinks will sparkle! In addition to cleaning so well, white vinegar has anti - bacterial properties therefor, this cleaner also kills germs and your drains will smell fresh and clean also. Happy cleaning!
Q:Is diamond lighter than steel?
Just compare the densities. The density of diamond is about 3.5g/mL. While there are different types of steel with different densities, steel is mostly iron, so the density of iron is a good approximation. Iron has a density of 7.87g/mL. Steel is over twice as dense as diamond, so the diamond sword would be lighter.
Q:What is the history of steel?
There's wide history of steel, you can read different tutorials online to know more about it. Check wiki for detailed information.
