Product Description:

0.4mm-0.5mm Pre-Painted Galvanized Steel Roofing Sheet PPGI/Hot Dipped Galvanized Steel Coil

Product Description

1. Galvanized steel coil simple introduction:

Galvanized steel coil means that steel coils has gone through a chemical process
To keep it from corroding, so this protective metal, zinc layers, does not get rusty as easily. The coating also gives the steel a more durable, hard to scratch finish.

(1)Thickness:0.14-1.2mm
(2)Width:600-1250mm
(3)Material:SGCC,DX51D,S350GD,SPCC,CGCC
(4)Zn:40-275gsm
(5)Surface:oiled,chromated
(6)Application: Corrugated,Wall,Roofing,Structure and so on
2. Galvanized steel coil technical processing:
1)Uncoiled and sheared
2)Cleaned using a caustic solution, which can remove oil/grease, dirt, and paint
3)Entry looper to revised and then annealing furnace
4)Steel is dipped into the molten zinc bath
5)Cooled in a quench tank to reduce its temperature
6)Post treatment and crimper

3. Galvanized steel coil quality control:
Strict procurement process---skillful technical workers---final products inspection
(resistance to corrosion, salt spray test, exposure test, machinability, thermal resistance)
---standard packing

4. Galvanized steel coil advantages:
1)Zinc coating has good adhesion
2)Resistant to corrosive factors
3)High strength&quality

Q:can anyone tell me were i can find strontuim steel dowel pins?
Strontium steel is created by soaking a mild steel in strontium chromate, which has a pH of about 4 or 5, roughly the equivalent of acid rain. Chromate affects the cathodic reaction, with reduction of Cr6+ to Cr3+, and the surface film was composed of magnetite and hydrated chromium hydroxide. The Strontium is a radioactive isotope. The acid bath permeates the mild steel causing it to become mildly radioactive. Simular to oil imprengation of brass and other metals. Strontium Steel has a very high value of inhibition. However due to it's radioactive properties it is not a commonly used or manufactured material. As for where to actually obtain Strontium steel dowels. I have no idea i would speculate that you would have to purchase the raw stock and have it machined into a dowel for you.
Q:Stainless steel versus plastic bowls?
My cats will eat their food from a stainless steel bowl but only drink their water from a plastic or ceramic bowl. This is a little far fetched, but maybe they get scared when they see their reflection in it. You know like when you look into a stainless steel toaster, you're face looks all distorted -- maybe the water in addition to the stainless steel is scary to them. The stainless steel pet dishes I have claim to be non-microbial (bacteria free) or something like that. Maybe whatever they use for this is affecting the taste of the water. The food, on the other hand, since it already has a flavor (water has no flavor), maybe it's not so noticeable.
Q:Car accident with a steel mailbox?
This will be a collision claim for you, if you have collision you can file a claim and you'll have to pay a deductible, whatever it is. The owner of the mailbox can also file a claim on your insurance since you damaged his/her mailbox. If you don't have collision coverage you won't get squat - this accident is 100% your fault. The steel mailbox didn't cause your car to get totaled, your driving did.
Q:Is there Non-Corrosive stainless steel?
All stainless steel will corrode in certain conditions. Some varieties are worse than others. For instance grade 409 which is used for car exhausts (and other things) will rust. For the most suitable grade call a local steel supplier which carries stainless steel. Some of these companies will have a catalog of available grades and the appropriate uses. It would probably help to let them know what types of chemicals are present and what temperature the water is. You may want to call several suppliers, the quality of answer you get may vary quite a bit from company to company. The cost of exotic grades of stainless can be quite high. you may have to use a less appropriate grade if you can't justify the cost. If corrosion is a very serious concern for this be forewarned that stainless steels can be contaminated by contact with carbon steel (ordinary steel). I have seen rust form on stainless steel after a carbon steel bar was set down on the stainless steel. The carbon steel will leave trace amounts under prolonged contact. I have even seen signs of contamination of stainless steel direct from the supplier.
Q:Silver OR Steel Jewellery.?
Steel necklaces are popular these days. They certainly have a different look than silver. I think they have an 'edgier' look, so it depends on your girl's style. If you like it, and you think she will, go for it. If you're into showing emotional affection, you could accompany the gift with some sort of card or note saying something about your love is as strong as steel. She'd probably dig it. I would.
Q:steel or aluminum on fixie?
Aluminum Fixie
Q:what is cast steel? what is the contain? it is diffrent from cast iron?
another name is Grey iron, come from groups of ferrous alloys
Q:steel or graphite?

Q:Steel used to be made in the \Bessemer Converter...?
Steel making today is a faster process as use Blast furnace which Coke Limestone Iron ore are fed into the top of the furnace. after these are fed in a exothermic happens and converts these ores into Iron. Iron is not strong enough to be used in thing this is formally known as pig iron. To convert Iron ore into steel it has to go to a process called the BOS Basic Oxygen Steel-making were oxygen is blown onto the iron ore for about 30 to 45 min and this then turns it into steel as all the impurities are taken out and this floats on top and known as slag and used for things such as road building. Once you have steel this is then pored into ladles and taken to the continuous caster and rolled into slabs, billets and bars and then cut off and rolled into a finished products and then taken to compniaes to be made into thins you see made out off metal such as skyscrapers. Hope this helps :o)
Q:Handgun steel question...?
The chrome moly alloy used in blued steel guns is the strongest thing out there today. Stainless guns sacrifice a little in strength in exchange for their rust resistance. Every maker has their own special alloys for various parts as well as proprietary techniques for hardening and tempering depending on the use a part will be put to. Keep in mind that the harder you make steel the more brittle it becomes. Especially true in knife blades also. A custom knife blade could be made much harder than they are, but would shatter under hard use.
