Structure of Al-Zinc coated steel coil

  Al-Zinc coated Steel Rolled Coil for Roofing

Description of Aluminum Zinc Rolled Coil
The detailed information for the Al-Zinc coated steel coil is as following and it is mainly using for roofing producing, making ceiling grid and all kinds of roll forming structure.
Thickness: 0.20mm to 1.20mm
Width: 914mm, 1000mm, 1200mm, 1219mm and 1250mm, or slit narrow strip according to customer request, can be slit from 20mm to 610mm.
Coil ID: 508mm
Coil weight: 3 tons to 6 tons
Thickness tolerance: +/- 0.02mm or according to customer request.

 

 Main Feature of Al-Zinc coated steel coil

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:Is Steel a Metal or Non - Metal ?
steel is an alloy - mix of two meatls alloy is a mixture and metal is an element so no comparision
Q:A steel rod AISI 1040....?
Aisi 1040
Q:Best steel for a all purpose knife?
There is no right one answer, because the term all purpose knife covers a very broad spectrum. The same knife that would be good for wood carving will not be the same for food prep, and will not be the same for general utility purposes. I'll just give you my humble opinion. For fixed blade, hard use blades. Where you will be doing bush tasks like chopping, carving etc... 1095 carbon is generally the standard. Now, 1095 is a great steel, it isn't the BEST steel. There are other steels that can outperform it. But for the price and availability its hard to beat. For folders, I prefer a decent stainless, like aus 8. It holds a good edge, and will hold up to any tasks you need a folding knife to do. Contrary to what you will read on the internet, stainless steel is not all crap. Its just that cheap stainless is just that, cheap. Stainless steel is only as good as its tempering process, some companies such as boker do amazing things with the steel and make for an impressive blade. Just stay away from crap stainless. So to sum up. 1095 for fixed blades. aus 8 for folders. These are both common steels used by different companies. If you get caught up on finding the perfect steel, you may overlook more important aspects of the knife itself. Unless your fixed blade is mostly going to be a food processing, and skinning knife, then I would suggest a QUALITY stainless as well. Remember that all high carbon blades need to be kept oiled or they will start to rust very fast. Btw, I suggest anyone looking into knives to check out mora fixed blades. Incredibly cheap, sharp and durable. They are the rockstars of bushcraft.
Q:Damascus steel sword question?
There are many makers that use blue on there Damascus. My question, what the heck are you wanting to mess with the finish for? If you had a true Damascus blade made that that thing cost a fortune, and I don't mean under a grand either. Then there is the question of what it is made from, some steel combinations react well to the gun blue, others not so much. If it is a stainless blade it won't work at all and you shouldn't be using it either. I can tell you, my Damascus blades start at $100 for a small cable knife and go up from there. If you wanted a sword it would push 10 g's easy. None of my customers would mess with the finish, most would cry if it got scratched. If it's has a pretty pattern don't mess with it.
Q:What is the difference between steel toe boots and composite toe?
steel toe boots are just that a piece of steel fitted over the toes, composite toe boots use other materials that are just as hard BUT they do not have the connectivity levels as steel. if you are working in a cold climate steel toes will freeze them toes right off, also electrical environments. my advice get a good pair of composite ones, and you get what you pay for, its worth the investment. more than you could ever imagine. proper foot support. helps legs cramps, back pain etc...
Q:Steel Buildings?
it is possible...but with the current ever rising cost of steel...it is more expensive than reinforced concrete..... ...one more disadvantage is tat u have to use large I sections for the columns as steel do not take compression as good as concrete... ..tat is why u see..almost all totally steel structures are bridges where tensile strength rules more than compression.
Q:What is INOX Steel?

Q:buying Stainless Steel refrigerator?
I think it's just the popular choice at the moment like avocado green was the hottest thing in the 1970s. I bought a Whirlpool Sateen. It has the look of stainless steel, but magnets will stick to it. There is no functional difference.
Q:Spyderco or cold steel?
What exactly are you using it for? Personally I would go with Cold Steel AK47. It's a good all around knife for hunting, combat, stabbing and slashing as well as everyday use. Well balanced tip and very little bladeplay which can be a problem with a cheaper knife. Both are good companies but the CS AK47 wins hands down for me.
Q:Mag. Wheel (steel and aluminum info)?
Negative facts for steel wheels: (1) Not as many style choices as aluminum. (2) Rust easily even when painted or powder coated, due to rock chips. (3) Heaver than aluminum, as far as fuel economy. Negative facts for aluminum wheels: (1) More sensitive to proper torquing of lug nuts. IE torque must be checked more often. (2) Susceptible to impact damage from road hazards much more than steel. (3) Need constant attention to prevent oxidation. Are these what you are looking for? I hope so. Wingman
