Description of Aluminum Zinc 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 Aluminum Zinc Rolled Coil for Construction Roof
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.

- Q: Many gerber knives are made out of what gerber calls high Carbon steels and I was wondering if anyone knew exactly what is this mysterious steel.
- Carbon, when added to steel increases the hardness of the metal. The higher the carbon content the harder(pure carbon = diamond) the blade will be and the longer it will hold its sharpened edge. Too much carbon however can make it too brittle to use as a blade. iron, carbon and chromium(for the stainless in stainless steel) mixed in the right portion makes a high carbon stainless steel knife. All of which is kinda pointless if the blade is not forged correctly.
- Q: hello friends, I have some old 7.62x54r on stripper clips its nasty gunk on it can i use steel wool to glean it and still have it fire safely?
- Jonathan, You won't have any problems firing the brass after you clean it with a solvent(such as brake clean) and steel wool. Keep in mind though, that brass is a soft metal. Use a less abrasive steel wool, such as 0000 to ensure you don't take too much brass off. Also, if you want your brass to be shiny, 0000 will ensure you won't have deep scratches in the brass. On a different note, there is a product called 'Flitz' that works great for polishing and cleaning up metals such as brass. It uses small abrasive particles in a liquid to polish and restore a bright finish. The ideal solution would be to run the brass through a tumbler or sonic cleaner. However, if you've only got a few cases and don't plan on using it that often they can be a bit pricy. Regards, Dustin All of the previous also applies to steel cases(just noticed they were steel), just add a good rust preventative and ensure the cases don't show any current signs of rusting as cleaning them up will most likely clean off any prior rust inhibitors. A rusted case is NOT safe to shoot.
- Q: What are the different types of steel coil grades and specifications?
- There are several different types of steel coil grades and specifications, including hot rolled, cold rolled, galvanized, and stainless steel coils. Each type has its own unique properties and uses. Hot rolled coils are produced at high temperatures and are commonly used in construction and manufacturing applications. Cold rolled coils are produced at lower temperatures and have a smoother finish, making them suitable for applications that require a higher level of precision. Galvanized coils are coated with a layer of zinc to protect against corrosion, while stainless steel coils contain a high percentage of chromium for added durability and resistance to corrosion. Overall, the choice of steel coil grade and specification depends on the specific requirements of the project or application.
