Product Description:

1. Pre-Painted Galvanized/Aluzinc Steel Roof Description:

With GI as base material, after pretreatment (degrease and chemical treatment ) and liquid dope with several layers of color, then after firing and cooling, finally the plate steel is called pre-painted galvanized (aluzinc) steel. Pre-painted galvanized roof is good capable of decoration, molding, corrosion resistance. It generally displays superior workability, durability and weather resistance.

 

2.Main Features of the Pre-Painted Galvanized/Aluzinc Steel Roof:

• Excellent process capability

• Smooth and flat surface

• Workability, durability

• Excellent heat resistance performance

• High strength

• Good formability

• Good visual effect

Q:grain growth in steel?
Well, I can't answer the question for you because, if the press bending is done cold, the grains will not grow (at least not with normal steel alloys). One wonderful thing about metallurgy is that the real answer is it depends because there are all sorts of weird and unexpected things that can happen. Cold work (which is what press bending is unless it is done hot or the amount of deformation is extraordinary high and fast so the metal heats up a lot locally) adds stored energy (strain energy) which provides one of the driving forces for recrystallization. Recrystallization is not a yes/no process, it is a process that happens as a function of time and temperature. Recrysallization of a cold worked structure will refine the grain size if done properly but the final stage of recrystallization is grain growth and you can end up with a larger grain size than you started with. The other thing that can affect grain structure is the deformation itself. There are all sorts of transformations that can happen due to the deformation process (twinning/martensitic is one) but, again, these don't usually qualify as grain growth. It may be that the question was incomplete, maybe the question is how does the press bending affect the final grain size after a subsequent anneal? The metallurgy of steels is fascinating because there are so many different microstructures that can be produced, hundreds (or thousand) different alloys, equilibrium and non-equilibrium phases based on composition and thermo-mechanical processing. Hope this helps
Q:Are there different types of steel that are used in construction of beach houses that withstand corrosion?
No, usually they are just coated or galvanized. To make a steel that is truly more corrosion resistant raises it's cost quite markedly, where as coatings are pretty cheap. Almost all structural steel is just A36 mild steel (like 0.1% carbon, 0.05% Mn, and not much else). There are higher grades of structural steel, and bridges are made with truly more corrosion resistant carbon steels, but for a house it's just not the case.
Q:Why is the steel tape tape head not fixed?
It makes sense to be irregular;You can see the standard ruler of steel roll head is a gap, when you take the time to object quantity, the head will indent the gap, so you measure is the size of the head from the head of steel;When you hook the object, the head will pull apart and you'll take the dimension from the end of the steel head.
Q:buying Stainless Steel refrigerator?
it is indeed in style.. but they're very hard to keep clean. take it from me. i have one. and if you even toush it with your finger. there's a smudge or mark. you have to constantly keep cleaning it. but it's no different that having a regular new refrigerator. they're just more stylish. but overall you should get the stainless steal one. just keep up with it. lol. hope it helped.
Q:Aluminum alloy rolling doors and color steel shutter door that good
Among them, aluminum alloy rolling doors and ordinary rolling doors, both from the appearance, environmental protection or safety, have considerable advantages. Aluminum Alloy doors can be sprayed on the surface of various colors and patterns, but also with the concavity of the wood, sand grain coated, highlight the noble temperament, improve grades, if it is used in shops, you can let your talent shows itself in many shops in the.
Q:Is clorox safe to clean stainless steel?
I think not. I owned stainless steel sinks before that were they were in style. I used Clorox and more on them and they always turned out great. found wiping them out with a paper towel made them shine.
Q:Conductivity question for electricity through stainless steel?
Stainless steel is not such a good conductor as copper and the only metal with better conductivity is silver. Additionally, stainless steel will corrode in certain very corrosive environments without the presence of oxygen - i.e. when immersed in salt water. If you're getting problems caused by corrosion of the copper contacts you use there may well be a trade off so my advice is to do a trial and see what works best. You can check the conductivity of metals by simple online search for the period table:

Q:question on shotguns and steel...?
Damascus steel in gunmaking Prior to the early 20th century, all shotgun barrels were forged by heating narrow strips of iron and steel and shaping them around a mandrel.[22][23] This process was referred to as laminating or Damascus and these barrels were found on shotguns that sold for $12.[22][23] These types of barrels earned a reputation for weakness and were never meant to be used with modern smokeless powder, or any kind of moderately powerful explosive.[23] Because of the resemblance to Damascus steel, higher-end barrels were made by Belgian and British gun makers.[22][23] These barrels are proof marked and meant to be used with light pressure loads.[22] Current gun manufacturers such as Caspian Arms make slide assemblies and small parts such as triggers and safeties for Colt M1911 pistols from powdered Swedish steel resulting in a swirling two-toned effect; these parts are often referred to as Stainless Damascus.[24]
Q:Stainless steel sword?
Ya it could kill someone if it was sharpened enough but from experience stainless steel swords don't get as sharp as Carbon or higher grade steel. Not to mention it would probably bend if you hit someone with it all the way. Hell the one I let some people who were chopping a bush ( just a normal bush ) they were playing around and it got bent. I'm going to say I can't suggest a stainless steel sword for anything other then handing on your wall. Not even going into the whole If you use a sword for self defense is it considered self defense? debate. It's a sketchy situation not to mention you would need training with a sword to actually use it without it just getting brushed off.
