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: This one may be tough to answer. I love Metal, all different genres of it. A while back i took the initiative to start a list of all these different Meal bands, genres, etc... etc... over time this list became quite extensive, extremely extensive actually... I became content with my creation. However, i made a mistake, and that was writing it all down on paper. My wife found it last week, she thought it was trash, so she threw it away... why she thought it was trash, i dont know. Anyways, im rebuilding my list but i need help. im going to list some genres of Metal and i need you all to list as many bands as you can that pertain to each genre. I know im asking a lot, but i am grateful for your help. #92;m/-Genres-Folk Metal Pagan MetalMedieval or Neo-Medieval MetalPower MetalSpeed MetalSymphonic MetalGothic MetalBlack MetalCeltic MetalMelodic Death MetalViking MetalMelodic Metal
- Well Anthrax, the famous thrash metal band have a rap metal song (in fact, one that founded the the genre of rap metal), and its lyrics are somewhat about rap and metal (For a heavy metal band raps a different way/We like to different and not cliche/They say rap and metal can never mix/Well all of them can suck our.../Sexual organ in the lower abdominal area!) and a lot of metal fans have liked it so....
- Q: Other metals that rust?
- Stupid much? I may be a genre Nazi when it comes to labeling bands, but your bigotry is extremely annoying. Hate liberals? If you're even using the word liberal than you're just another brainwashed conservative or fascist as I like to appropriately label.
- Q: give me some bands of todays heavy metal death metal or thrash metal scene.also give me some of the names of some awsome metal frontman of some bands in the metal seen today espicially the ones that sing and play guitar for them
- Metal Oxide implies that you have a metal and oxygen bonded together. Atomic mass of Oxygen: 15.9994g % of metal oxide containing oxygen: 100 - 91.4 = 8.6% This means that 8.6% of the mass is 15.9994g (15.9994g / 8.6%) * 91.4% = 170.0401g The mass of the metal is 170.0401g. Looking at the period table, we do not see a metal with that mass. We can assume then that more than one atom of the element may be present. Start by dividing the mass by 2. 170.0401g / 2 = 85.0201 g This is rubidium's atomic mass. The molecule is thus Rb2O.
- Q: Crying metal
- first rock songs would be something like elvis or little richard buddy holly something along those lines there really isnt a first of anything b/c it was more of a eveloution into what it had become metal well heavy, dark, black, hard rock could be a metal like the big hair bands heavy would be like pantere tool twisted sister drowning pool dark and black would be like deicide and the difference between the two has to do with the drums and the style in which they sing or lack there of also what its they sing about
- Q: What do you like and dislike about these sub genres of metal?Power MetalDeath MetalBlack MetalThrash MetalMetalcoreDoom MetalDeathcoreStoner Metal Groove MetalIf I forgot about one please add it and state your opinions.
- non metal + non metal = covalent (sharing of bonds) metal + non-metal = ionic (giving away of electrons by one and receiving by the other) e.g of covalent = O2, CO2, Cl2 e.g of ionic = MgCl, NaCl, NaOH
- Q: I know it'll find anything shiny, but which is the best and cheapest metal dector?Please and thanks!
- False Metal = Commercialized, watered down, and often incredibly generic bands that are passed off as Metal by MTV and Hot Topic despite the lack of Metal influences in these bands. Mainly comprised of Nu-Metal bands and certain Post Hardcore-influenced Metalcore bands. Examples: Slipknot, Atreyu, Bullet for my Valentine, Korn, Linkin Park etc. Yep, I like BFMV and Linkin Park.
- Q: Any form of metal works.
- Generally aluminium is used for making aeroplanes. TO be specific Duraluminium is used in the construction of the aircrafts body. This has a property of great strength and light weight and hence is suitable for aircrafts. For smaller aircrafts a special fabric is generally utilized for covering up the frame work.
- Q: Is it possible to react a metal with hydrogen? What would this be called ( for example would cu and h react to form copper hydryde?). I have observed in electolysis cells that the hydrogen metal (if it is not a good anode) turns black. Is this the chlorine frome the salt changing the andode? The other connection turns red from rust. Would this be possible, because hydrogen requires one electron to fulfill its energy level (2) and metals (such as copper) are looking to lose electrons? If not, why?
- Well, we happen to know that the metal in Drano is aluminum. To identify the metal, I would isolate the pieces of metal and measure the density. Most people think that the aluminum reacts with the NaOH. Actually the NaOH dissolves the oxide coating that covers the aluminum metal. Once the Al2O3 is dissolved, the aluminum metal reacts with the water to make aluminum hydroxide and hydrogen gas. Al2O3S) + 6NaOH --> 6Na+ + 2AlO3- This exposes aluminum metal which reacts with water: 2Al + 6HOH --> 2Al(OH)3(s) + 3H2(g)
- Q: I thought it was rap mixed with metal, but I constantly am being told that certian bands I thought were something else, like Slipknot for example, are actually Nu Metal. So, what exactly IS Nu Metal?
- Dragonforce Accept Judas Priest(I guess this could be considered power metal) Nightwish Metal Church Demons and Wizards(side-project of the bands Iced Earth and Blind Guardian)
- Q: Can you give some names of some Ferrous Metals? Thanks =)
- the difference between metals and non-metals are that the atom of a non-metal that non-metal radily accepts electron or give one but metals do. Metals are good conductors of heat and electricity. 2. They are malleable and ductile in their solid state. 3. They show metallic luster. 4. They are opaque. 5. They have high density. 6. They are solids (except mercury) 7. They have crystal structure in which each atom is surrounded by eight to twelve near neighbors 8. They have one to four valence electrons. 9. They have low ionization potentials; they readily lose electrons. 10. They are good reducing agents. 11. They have hydroxides which are bases or amphoteric. 12. They are electropositive.
