1,Cast Iron Manhole Cover Description :

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.

 5FAQ:

We have organized several common questions for our clientsmay 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: looking for a good metal band that is just insane on guitar. something with a heavy metallica-like crunch to it, and with out of the world solos. is there like a screamo band like that, besides lamb of god?
Well okorder
Q: So well, I'm kinda exploring other genres of metal and I was wondering if you guys know some good folk/viking metal, already know of Ensiferum (epicness) and Wintersun (same story).
They react vigorously with water...vigour increasing down the group.
Q: Like Thrash metalDeath metalGoove metalNu metalMetalcoreEtc
Yeah, I agree: Nightwish. Also look at a band called Metal-X's YouTube video: Classical Metal
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.
No Spokey Dokey is wrong!!!!! A co-valenet bond is formed when a non-metal reacts with a non-metal.e.g 02 is a COVALENT COMPOUND.
Q: ok their are huge fights over what is quot;realquot; metal people say any band that is in any genre with quot;corequot; in it isn't metal or nu-metal isn't. some say power metal isn't real metal since it uses clean vocals and sometimes symphonic sounds like rhapsody of fire. well you get what I am asking. people say that these certain bands are metal and these others arn't. personally I consider a wide range of bands to be metal except for a few mostly the bands supported heavily at hot topic since their quot;fansquot; are mostly young kids who think dressing quot;scene/emoquot; is cool and since I never see any older metal heads liking any of these bands so yeah
Death metal is an extreme subgenre of heavy metal music. It typically employs heavily distorted guitars, tremolo picking, deep growling vocals, blast beat drumming, minor keys or atonality, and complex song structures with multiple tempo changes. Black metal is an extreme subgenre of heavy metal music. Common traits include fast tempos, shrieked vocals, highly distorted guitars played with tremolo picking, blast beat drumming, raw recording, and unconventional song structures.
Q: Name one metal which must be extracted from it's metal ore by electrolysis, rather than by using carbon.... Please Help!
There have been a lot of new Twisted Metal games since TM4. in order from oldest to newest AFTER TM4: Twisted Metal: Black (2001) Twisted Metal: Small Brawl (2001) Twisted Metal: Black Online (2002) Twisted Metal: Head-On (2005) Twisted Metal: Head-On: Extra Twisted Edition (2008) There is also plans for a new Twisted Metal for release in 2011. Most, if not all, of the mentioned games were for PS2 and possible the original Xbox. I don't think there's ever been a Twisted Metal release on the PC.
Q: METAL KICKS F U C K I N G A S S! What are the Metal by Numbers lyrics? Its awesum.

Q: i have been listening to metal for a few years but i still feel like there are a lot of bands i'm missing out on. currently i'm listening to bands like finntroll,sepultura, amon amarth and blood shot dawn. i'm not a huge fan of black metal but i don't listen to to that much so maybe a few black metal bands for beginners would be nice also i'm not really interested in any core bands especially grindcore. I figure im mostly in the melodic and folk stuff but i wouldn't mind getting into some of the harder bands though. if anyone can help it would be much appreciated

Q: Electricity is defined the flow of electron.Then why the non metal do not conduct the electricity.
The reactivity of metals depends on the ease with which they lose electrons. The most reactive metal atoms (K, Na, Ca, ) lose electrons easily to form positive ions. Less reactive metals such as Cu and Ag do not lose electrons easily. In the reactions you are thinking about more reactive metals will displace less reactive metals from solutions of their salts because they are able to 'force' the less reactive metal ion to take electrons and the less reactive metals are displaced from teh solution eg Zn (s) + Cu2+(aq) ---> Zn2+(aq) + Cu Zn atoms give 2 electrons to Cu2+ ions
