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: Does anybody know some good chats for metal music?
- pee yew
- Q: Are these metals or non matels?-Semi Conductors-Halogens-Noble Gases
- metal is an element smart one, no one invented it
- Q: Or any metal band
- Metals - good conductors of heat and electricity, good reflectors of light, malleable, ductile, tend to lose electrons in forming bonds, low electronegativity, low ionization energy Nonmetals - poor conductors of heat and electricity, poor reflectors of light, soft or brittle, tend to gain electrons in forming bonds, high electronegativity, high ionization energy
- Q: CTeGaXePoAgCaGdWhich of these are non-metals?
- Metals crystallize but owing to their other characteristics the crystals are rarely discussed. Some metals such as gold are too soft to use if not alloyed. Alloying can deal with substitution of specific metal atoms into the matrix so one might achieve the same strength with a lighter density. Some alloys are made to resist wear by achieving hardness--Read more about (Rockwell Hardness). or precious metal as such as gold and alloys of 12, 14, 18 and 24 karat. Other alloys provide for a more uniform expansion or resistance to expansion. or resistance to corrosion, such as brass or a controlled corrosion such as the patina of bronze
- 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: 10 pts. for the most knowledgable metal head on here.
- What exactly would you consider metalcore and how is it not metal? Bands like August Burns Red and As I Lay Dying have just as much a right to be considered metal as anything else. Elitists that ask questions like this are the reason metal is so fragmented in the first place. Hard rock nu-metal bands like Disturbed and Korn I can see being excluded but I don't understand one of the heaviest genres being left out.
- Q: and how many metal gear games are there and howmany metal gear solids?
- Metal, because it has structure and is more versatile than Hardcore. There are also more styles and requires more skill than hardcore. Hardcore focuses on repitition, chanting, breakdowns and stupid dancing. You basically tune your guitar to drop C and use one or two fingers to play the same riffs over and over. Hardcore is so boring that it occasionally tries to get lumped in with the metal crowd by adding heavier distortion to their guitars. So yeah, I pick Metal.
- Q: I'm Crazy about Metal music....so i wanted to know about the differnce between death n Black metal musi?...
- all labels are absolute crap now there's no way you can look at them bands label themselves on how they want to be seen when most of the times now they aren't actual that type of music I prefer black metal extreme metal is a waste of music that some band just came up with to make themselves sound cooler hardcore metal is probably the same thing, but there's black metal out there that is harder and faster then hardcore really, just listen to bands you like, who the hell cares about labels
- Q: And is Nu Metal really dying?
- Metal have delocalized valance electrons. With other atoms we look at the s and p orbitals mostly but with metals we also take into consideration the d block electrons in metals these can be bonding electrons to form complex ions When thinking about conductivity and metals picture the atoms in a organized crystal structure with the electrons moving freely between the lattice work, This sea of electrons that are delocalized make it easy for metals to conduct both heat and electricity.
- Q: can anyone name (all) the metal gear solid ps2 games? & how many there are?
- That mainly depends on who you ask. Personally, I consider most the Metalcore bands such as Killswitch Engage and Time of Grace to be Metal. Others maybe not. I think Deathcore would be, I haven't really listened to any of it though.
