Structure of Aluminum Zinc Rolled Coil

 Prepainted Aluminum Zinc rolled Coil for Construction

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. 
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:How is steel coloured?
Steel can be plated(Chrome),Blackened(Black Oxide),Powder coated(color of your choose).All of this is done to prevent rust.All of these aforementioned processes can be worn off through being used.I suggest polished Stainless steel.
Q:Safety of steel-capped boots?
Hey Bunny:) Glad you asked! I know of no one ,at all,that thinks steel toes are better than good reflexes and the ability to move faster! Wellies give flex,Sport shoes give speed, Jods(Paddocks) are the work boot of choice..and if there is one thing we know about horses, nothing happens in slo-mo! There is a fiberglass toe protector a person could use.. I guess..not this person though. Added to the factor that they have that bumpy sole not suited for riding, and a bad heel, and are just plain too heavy. And ankles! nothing special there. My flatmate(roomie) is an Equine reproduction Vet and a Polo Player, and no-one there has anything but jods and wellies. No clunky boots please:) Come to think of it, its been years since Ive mashed a foolish toe..and that takes into account trailering vetting and young-stock work....Yes I vote for movement over safety ** there are no horse-goods for sale with toe caps ** Three cheers for mobility bunny! (and wellies disinfect real nice too)
Q:Carbon Steel or Stainless Steel? ?
Carbon steel will corrode much more easily than stainless steel, and stainless can be made stronger than carbon steel. Stainless steel is also usually heavier than carbon steel, which helps to control recoil when the gun is fired (recoil is not eliminated, only reduced). Stainless steel can also be polished to a mirror finish, so it doesn't have to be chrome-plated for that shine. Probably the biggest plus to using stainless over carbon steel, though, is the fact that it is far less prone to crystalization than carbon steel. When steel crystalizes, it becomes brittle, and can break at the worst possible times. Bad thing about stainless: It generally costs more. Aluminum is much lighter than any steel, size-for-size, and can be just as strong, if not stronger, than steel; I've worked with aluminum alloys that require special-made tooling. The difference, besides the weight issue, is that aluminum (even most alloys) will become softer when it is heated to a specific point -- which is why it is not used for the barrels of firearms using explosive powders as the propellent source. Because of the cost of the alloys which can withstand the heat generated in the barrel of a firearm, it is just less expensive to use a steel barrel. And for a fella that is so pro-gun, the previous answerer sure seems ignorant of 'em.
Q:Best battle-ready katana steel?
This Site Might Help You. RE: Best battle-ready katana steel? I've been looking into battle-ready katanas a lot lately. And I've come across some debates between the best forges and steels to be used for them. The functional katanas I use now are Musashi brand katanas, using 1045 carbon steel. They each cost roughly $200-$250. The straight carbon...
Q:Why can hot rolled coils be placed outside?
Because the stress of participation should be eliminated
Q:Steel shot?
All buckshot I can think of at the moment is lead. Steel shot is used for waterfowl hunting because lead is illegal for that use. They don't want all that lead shot falling back in the water and causing lead contamination. There would be no reason to make steel buckshot, and it would be pretty ineffective. Steel is much less dense than lead. So a steel 00 pellet would weigh much less than a lead 00 pellet. So it would carry a lot less energy to a target. Buckshot is used for just that, Bucks. Well large game like deer, bear, and for self defense. In uses like that you need that extra energy. Lead shot is used for everything, except where lead shot is illegal, which is waterfowl hunting. Steel shot really isn't very popular anymore. Waterfowl shot just can't be lead. It doesn't have to be steel. They've come out with other stuff, like bismuth, that is a lot more dense than steel, but still not as dense as lead.
Q:Best Quality Steel...............!!?
Please specify what kind of steel, is it structural steel (like wide flange, channel or Z-section) or reinforcing steel? For structural steel, all steel members that passed the requirement of ASTM-A360 are the best quality. While for reinforcing steel, it should passed the requirement of ASTM-D3963 for epoxy coated and ASTM-A615 (Grade 60) for deformed bars.
Q:Are steel doors insulated?
Steel doors are insulated,but will feel cold in the winter.Feel all around the door weather stripping area and the seal at the bottom of the door to see if air is getting in.
Q:how to repair rusted steel concret?
The rust needs to be removed by what ever means works best for your situation.. Often a twisted wire wheel on a 4 1/2 angle grinder works quickly... a hand wire brush may work well for you, or just plain sandpaper and a LOT of elbow grease (hard work) will remove the rust. From there, a coat of primer paint made for steel. Any hardware store in your area would have such a primer, in quart cans or spray cans. Once that is dry (a good 24 hours for most formulations), you can spray or brush paint the beam most any color you wish.. I've had very good luck with acrylic enamel paints for such projects.. IF your steel is badly pitted, you should consider getting it inspected to insure it will still hold up or support what ever it was installed to do. If you want a smooth finish, once the rust removal is done, you can fill in the dips and pock marks with an auto body filler (Bondo is one brand name)... It comes in 2 parts (the main filler and a hardener) that are mixed well and used to fill in the holes and divits with a plastic spreader.. Once hard (in a few minutes with most brands of filler), sanding with sandpaper and a sanding block will smooth out the finish very nicely. From there, the same primer mentioned above and paint will finish up your project... Hope this helps some... Good Luck!
Q:is stainless steel plated or alloyed/mixed?
stainless steel is an alloy normally iron with additions of C, Mn, Ni, Cr, and Nb - amounts added depend on properties required. Corrosion resistance is due to a very thin but dense layer of chromium oxide which forms at the surface and prevents further attack. Ordinary steel on the other hand becomes coated with a porous layer of iron oxide(rust) through which the atmosphere can pass and cause further corrosion.
