1,Cast Iron Manhole Cover Description :
A manhole cover is a removable plate forming the lid over the opening of a manhole, to prevent anyone or anything from falling in, and to keep out unauthorized persons and material.
Manhole covers are often made out of cast iron, concrete or a combination of the two. This makes them inexpensive, strong, and heavy, usually weighing more than 50 kilograms (110 lb). The weight helps to keep them in place when traffic passes over them, and makes it difficult for unauthorised people not having suitable tools to remove them.
A manhole cover sits on metal base, with a smaller inset rim which fits the cover. The base and cover are sometimes called "castings", because they are usually made by a casting process, typically sand-casting techniques.

5,FAQ:
We have organized several common questions for our clients,may help you sincerely:
Q. Can I fit a square manhole cover into a round chamber?
A. Yes, there are a select few manhole covers which are square-to-round, meaning they will fit square or round chambers.
Q. I have a heavy traffic manhole cover but it has been broken by a forklift, why?
A. Forklifts have solid wheels which apply pressure differently to standard pneumatics and therefore covers must be specially adapted to suit this.
Q. I’ve measured my clear opening size but none of your covers match it, can you offer anything?
A. It’s likely that your cover is quite old and in imperial measurements which are no longer manufactured. However, we can offer bespoke solutions with manhole covers made to the specification you require.
Q. The project I’m working on requires a manhole cover with a quality finish, what’s available?
A. Naturally, galvanised steel of black polypropylene aren’t always ideal, and so we offer brass or stainless steel edging, as well as complete stainless steel covers.
Q. Odours are coming through where I have installed my manhole cover, why?
A. Your cover must be sealed and locked, or neoprene sealed, so you would require a T-Range Cover, or if you require a solid top, a selection of the PC range (e.g. PC2BG3, PC6CG3, not PC2BG) are suitable.
Q. I need access through my manhole cover on a regular basis, is this possible?
A. Yes, the majority of covers have built-in lifting keys, and for those that don’t we also supply lifting keys. However, the best way to obtain easy access is to have a bespoke, hinged manhole cover.
- Q: Any kind of metal
- Oh no....A metal combined with oxygen gives a metallic oxide. For example: 4Na + O2 --> 2Na2O Another one: acid + base --> salt + water This is a double-displacement reaction (neutralization, to be more exact). metallic oxide + water --> metallic hydroxide CaO + H2O --> Ca(OH)2 :)
- Q: i always thought it was a mineral or rock, someone told me it was a metal, anyone know?
- Metal Oxide Water
- Q: which superheros have anything to do with metal
- I try to go for that original heavy metal sound, with maybe some thrash metal bands. Here are my suggestions and some good songs to get you started off: Artist: Song--format Led Zeppelin: Stairway To Heaven Black Sabbath: Paranoid Metallica: Master of Puppets Iron Maiden: Hallowed Be Thy Name Judas Priest: A Touch of Evil AC/DC: Back in Black Megadeth: Holy Wars That's pretty much my preference. I tried to stick within metal, though Led Zeppelin has a blues sound to it too. I could also give you some hard rock bands and important bands influential to metal if you need.
- Q: which do you prefer? I personally prefer metal of course. :)
- I like some death metal bands, though Im actually more into the symphotic metal genre (things like Nightwish, Epica,Sirenia, etc.) I've never really been big on thrash metal though, but maybe its just because I havent listened to the right bands. :-P
- Q: I listen to all kinds of metal. Just shopping for suggestions on what CD to buy next.
- Thrash Metal – Thrashers (Death Angel) Power Metal - Eagle Fly Free (Helloween) Black Metal - Unholy Black Metal (Dark Throne) Death Metal - Death Metal (Possessed) Heavy Metal – Painkiller (Judas Priest)
- Q: 1) Which person in any metal gear game is your favorite?2) Which metal gear game is your favorite?3) Do you think metal gear will ever be made into a movie?
- try a song thats a bit softer and not as aggressive, like iron maiden or judas priest. no slayer
- Q: yes im asking this because there are so many like metal,clash metal, goth,black, and hardcore which sounds the same has metal...i know you all are going to commit on that but yes what are the difference that i am not seeing in the music can any one clarify this for me please and if you can list all the types of metal
- For the best answers, search on this site okorder
- Q: i was listening metal and rock since i was 5...i loved it so much...but there is one thing that i just couldn't understand...really quot;what is the difference between death and heavy metal??quot; i am sure that death metal have a lot of screaming in every song,but i just cannot figure that out!.. :P thank again..
- a metal is a chemical element whose atoms readily lose electrons to form positive ions (cations), and form metallic bonds between other metal atoms and ionic bonds between nonmetal atoms.[ and Metalworking is the process of working with metals to create individual parts, assemblies, or large scale structures
- Q: are alkali of alkali earth metals impossible of degrade by chemical process
- according to my opinion your question would be like what is the only pure metal which is available in the earths crust if that was your question the answer is platanium
- Q: How are some metals shiny and some dull?
- For the metal-to-metal coefficient of static friction, it depends a lot on the composition of the different metals, their surface finish, and the amount and composition of any lubricant or surface contaminant. Ditto for leather on metal. As a rule, for clean, smooth metal-to-metal surfaces, dissimilar metals tend to give lower values for static friction than two surfaces of the same metal that would have a tendency to stick to each other (i.e., seize) and refuse to slide at all. This is especially true if one of the metals is very hard and the other is relatively soft, which is one reason why sleeve bearings are made of relatively soft stuff. It also helps if the surfaces are smooth but not too smooth. Minimum values you can expect for the coefficient of static friction would be in the range of 0.1. From a theoretical standpoint, leather on metal is even more complicated than metal on metal because the leather is a chemically and structurally complex mix of substances that can be expected to change with age, usage, and environment. That said, the tables in the reference will give you some idea what to expect.
