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: I'm trying to bend stainless steel spoons, forks knives etc. for an art project. Will heating them help bend them into certain shapes or will heat only strengthen it? What is the best way to bend stainless steel?
- We are regular buyers of such bends.
- Q: How are steel coils inspected for width using laser measurement?
- Steel coils are inspected for width using laser measurement by placing a laser sensor on one side of the coil and a reflective target on the other side. The laser beam is emitted towards the target, and the reflected beam is analyzed by the sensor. Based on the time it takes for the beam to travel back and the angle of the beam, the width of the steel coil can be accurately measured.
- Q: Does anyone know what is 12 gage Cold Rolled Steel meaning? Also, help me to describe it.Thank you so muck ~!Mark Lin
- It's gauge.
- Q: I made a wood crossbow body but all I need is a bow which I want to be metal. I've used a thin steel sheet that I cut to appropriate size but when it bent with the string strung, it never went to original shape after being shot. I used a slightly thicker and it wouldn't bend at all. Anybody know what thickness and type to use? Any real answers are very appreciated. Thanks.
- You are trying to use plain carbon steel which only can be bent a little bit if it is to return to its original shape. You have to use spring steel or high carbon steel that is intended to be bent a lot and still recover to its original shape. Most people making crossbows with metal bows get a piece of steel from a leaf spring of a vehicle and grind it to shape. A steel bow cross bow almost always needs a very strong trigger mechanism and a miniature wench to pull the steel bow string into position. You might be better off making the bow of wood.
- Q: How are steel coils used in the production of automotive exhaust systems?
- Steel coils are used in the production of automotive exhaust systems as they are shaped and formed into various components such as pipes, mufflers, and catalytic converters. These coils are cut, bent, and welded to create the necessary shapes and sizes required for efficient exhaust flow and noise reduction. Additionally, the strength and durability of steel make it an ideal material for withstanding high temperatures and harsh conditions that exhaust systems endure.
- Q: What are the different coil packaging machine configurations used for steel coils?
- There are various coil packaging machine configurations utilized for steel coils, each tailored to specific coil sizes, weights, and packaging needs. 1. The horizontal coil packaging machine is designed for smaller steel coils. It is typically equipped with a conveyor system that transports the coil horizontally throughout the packaging process. It may incorporate automatic coil centering, wrapping, and strapping features to guarantee secure and efficient packaging. 2. The vertical coil packaging machine is suitable for larger and heavier steel coils.

- Q: I have the game of the year edition for fallout 3 but there's no mission or quest saying it's called broken steel so what is it actually called and where is it? Please describe the quest in case I mightve already done it without even knowing.
- Broken Steel fixes the original ending of the game so that you can continue past the end and continue exploring. The Broken Steel missions also take place after the original ending of the game. One way you can tell if Broken Steel is working though is if you are finding enemies added with Broken Steel (Super Mutant Overlords, Hellfire Enclave Troops, and so on), and if you can level up past level 20 and get new perks added between 20 and 30. You can even see all of these new perks any time you level up, so next time you level up, scroll down and see if there are new perks below the level 20 perks. If there are, then Broken Steel is working properly.
- Q: For example, (and this is weird) if I were wearing a steel collar and I needed some way to remove it, with limited supplies.Force is difficult because it would be around my neck.Chemical cominations are great- but they have to use VERY common products. And I'm not sure what to use.Other ideas?
- Your best bet would be a grinding wheel attached to a small electric motor. Even if you slipped, your skin is too soft to be cut by the dull wheel. Steel, however, is easily cut. But perhaps you don't have access to electricity or pressurized air to run such a tool. In that case, a simple file would work well, though you'd be somewhat more likely to injure yourself. If you had no tools, but access to whatever chemicals you wanted, you could try a weak acid. This would take a long time, and require constant scrubbing to bring fresh acid into the pits in the metal, but it would eventually eat through the collar.
