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.

4，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: please..i want loads of cool names of some metal rock bands
- normal okorder
- Q: SKA OR METAL!?
- metal legs. The stress placed on the body by always carrying metal arms would be bad for your back and legs.
- Q: someone said it was one of the genres of metal in a answer to my question but I don't know what it is!
- Well I can think of a number of them, though probably not all ! You must first find out about the characteristics of the metal, type of metal,- as a number of things are classified as metal , - such as steel, aluminum, copper, alloys, like brass nickel etc. Then you have tensil-strength, - which is the hardness of the material, - as working the material (such as stretching, bending,) in order to get the material formed like a (car fender or a bowl for instance). You will also need to know how to prevent oxidation (called rust or corrosion), and what primer/paints required for different metals. Also joining different metals, welding etc. So you can see that you need to learn a lot!
- Q: One of these bands are considered quot;Metalquot; and one is not. Which is which?
- Well the reason why I don't have much love for Nu is that it's too generic and unoriginal like the songs have the same 3-5 chords and no solos, the teen angst lyrics, and also the vocals are midrange mediocrity. I'm not saying Nu Metal is bad, I'm just giving my opinions about it. They are some exceptions in Nu Metal like Deftones, System of a Down, Sevendust, and some of KoRn's early stuff.
- Q: like metal is....and non-metal is..
- Every thing in this world tries to gain stability metals also lose electrons to gain stability by attaining the configuration of nearest noble gas.Metals usually have 1,2 or 3 electrons in their outer most shells so it is difficult for them to gain electrons( for completing their outer most shells),as compared to lose elctrons.Thats why metals lose electron.
- Q: I hate to be too much of a genre know it all, but this has been bugging me for a long time. I love all sorts of progressive metal bands, but I don't know what differentiates them from the other genres of metal. Bands like Symphony X, Suspyre, and Pathosray are examples of progressive metal bands that I like.
- 1) as almost all nonmetals are non conductive chance to electro magnetic interference is very low...( so great chance in electronics 2)its conductivity is almost independent of temperature 3)light in weight
- Q: (I listen to anything from Black Metal to Alternative, and I am just getting confused. Isn't Screamo, Thrash, Power Metal, and Black Metal, STILL METAL???)
- Heavy metal (often referred to simply as metal) is a genre of rock music[1] that developed in the late 1960s and early 1970s, largely in England and the United States.[2] With roots in blues-rock and psychedelic rock, the bands that created heavy metal developed a thick, massive sound, characterized by highly amplified distortion, extended guitar solos, emphatic beats, and overall loudness. Heavy metal lyrics and performance styles are generally associated with machismo and masculine sexuality.[3] Early heavy metal bands such as Led Zeppelin, Black Sabbath, and Deep Purple attracted large audiences, though they were often critically reviled, a status common throughout the history of the genre. In the mid-1970s, Judas Priest helped spur the genre's evolution by discarding much of its blues influence; Mot?rhead introduced a punk rock sensibility and an increasing emphasis on speed. Bands in the New Wave of British Heavy Metal such as Iron Maiden followed in a similar vein. Before the end of the decade, heavy metal had attracted a worldwide following of fans known as metalheads or headbangers.
- Q: This is my Physics homework and I'm stuck because I was ill for a few lessons.Whole question: ''Compare the similarities and differences between the process of conduction in metals and non-metals.''
- Metals will weaken acids so the pH will get higher. e.g. dilute HCl pH =1 add metal e.g. magnesium pH MgCl2 solution = 7
- Q: Explain how a pure metal is held together. (Include a definition of a metallic bond in your explanation). I'm not so worried about the information in the parenthesis but I do need to know how a pure metal is held together. The more detailed the explanation the better.
- here are a few, death metal bands: amon amarth children of bodom dark tranquillity dethklok insomnium kalmah nile ( although these guys are considered tech death, they also have really folly and melodic riffs and their drummer is the best) nightrage folk metal: balckguard claim the throne eluveitie (king of folk metal, listen to inis mona) ensiferum krampus suidakra black metal: behemoth cradle of filth dimmu borgir equilibrium necrophobic opera IX
- Q: If two metals that start at the same temperature and we add heat- metal B changes water from 5?C to 15?C, and metal A changes the temperature of the water from 5?C to 45?C, which metal has the higher specific heat?
- Black Metal sounding vocals doesn't make it Black Metal. They're probably labelled by some moron who hasn't a clue what REAL Black Metal is. The band sounds pretty tight though they need to lose that singer, even as a blackened style vocalist(?) he sucks! ps I consider Dragonforce as Power Metal just not good Power Metal.
