General Information Of  Prepainted Galvanized Steel

 

With GI as base metal, 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 steel. Pre-painted galvanized steel is good capable of decoration, molding, corrosion resistance. It generally displays superior workability, durability and weather resistance.

Q:Question for carbon steel ?
None. Mn is a trace impurity in all steels, if you look carefully enough. If you want to find a steel where Mn is not intentionally added, start looking at the alloy composition specifications, there are hundreds of steels. Why are you worried about Mn? Mn is typically added to steels for a very good reason.
Q:Does stainless steel cookware really cause cancer?
No, the studies done and published in JAMA showed that the over cooking of the food MAY lead to higher incidents of SOME cancers but the cookware did not contribute. Humans do well filtering heavy metals which is why spring water tastes so good to us. This author is wrong if not she'd win a Nobel prize for finding a simple way to prevent cancer.
Q:Stainless Steel Appliances?
Stainless steel is pretty much stainless steel. The differences in tone you can get is when you get stainless steel look appliances. They tend to be a bit more like a charcoal color than true stainless steel color. When I bought my house, it had a stainless steel GE microwave, dishwasher, and stove, and a Braun stainless steel range hood. When we remodeled last year, we got a Maytag Ice20 stainless steel refrigerator and a Kholer stainless steel sink. They all look fine together.
Q:Steel Clutch Vs. Transmission?
First of all it's not really a steel clutch..it is called a sintered iron clutch disk... a sintered iron clutch has a very aggressive amount of friction and is generally only used in racing application because of this...also it is ushually a non sprung disk. all of these factors = a very abrupt ingagement of the clutch which will shock the driveline very badly...say he's making 400hp and has really sticky tires..there is bound to be a weak link between the engine and the tires, in a factory driveline this would probably have been the clutch(it would slip) but since he has upgraded it he has now found the next weekest llink..in this case the transmission, he either needs to look into a beefier box or not launch the car so hard.
Q:Question about steel type used in bridges.?
Do you mean galvanized steel?
Q:Conductivity question for electricity through stainless steel?
I can only guess. I can't even tell if you are plating some other metal with copper OR if you are plating copper with some other metal. you state that you use the copper clamps only to confirm the current, but I don't see how that works. I suspect that the plating current actually goes through these clamps, so conductivity is very important. But, the conductivity of SS is about 1/5th that of copper, so that will definitely have an effect, and not a good one. .
Q:How durable is stainless steel jewelry?
This Site Might Help You. RE: How durable is stainless steel jewelry? I know sterling silver can tarnish, so I was just wondering, how does stainless steel hold up?

Q:Stain on stainless steel sink...?
in your super market their is a pad that is green and is called scooth bright use it on the stain and it will remve it
Q:A simple question: Corten steel?
Bill summed it up pretty quick and provided a link. For some reason you are focusing on the copper content when it really is insignificant in the overall picture of the sun hitting its surface. If you could elaborate more, maybe we could offer a better answer.
