Product Description:

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.

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:Good metal bands??? :)?
semiconductors - metal halogens - nonmetal noble gases - nonmetal Semiconductors are used for the transference of energy. They can be found in things such as solar panels. Halogens are the elements like chlorine and bromine and are the elements in the column second to the right. The noble gases are... clearly not metal... they're gases... it's in the name!
Q:So how many metal heads do we have online right now?
Thrash,Crossover,Heavy,some Death, some Doom
Q:how do metal detectors work? magnetism?
Check me out on YouTube. I mix dubstep with metal. I remix pop songs and rap songs into metal dubstep. Trust me you'll love my work.
Q:Thrash Metal?????????
The only real difference is the energy level of the valence electrons. In a metal the electrons are free to move. In a non-metal they are not free to move.
Q:identity of metal question?
Alright, but what's the question? I define Metal as heavy on guitar or drums, has a lot of screams (although some alternative metal has far more singing) and with generally angsty or angry lyrics. Does that answer your question?
Q:Where and when was death metal and metal originated?
It's hard to properly go into detail over the differences but they're very different. Aesthetically, their appearances are different. Death metal artists just look like normal people really, while a big part of black metal is use of corpsepaint and other **** like that. Also in the 90s there was a big feud between Norwegian black metal fans and Swedish death metal fans.
Q:is black sabbath metal or rock?
In flames == Melodic death metal Tool==Art rock. Progressive metal, progressive rock Killswitch Engage==Metalcore Dream Theater==progressive metal. progressive rock Alice in Chains==alternative metal, grunge, hard rock, heavy metal.. Soundgarden==alternative metal, alternative rock, grunge The Offspring==punk rock.pop punk. alternative rock. skate punk Nine Inch Nails==alternative rock. industrial rock Firewind==heavy metal. power metal. thrash metal Beastie Boys==hardcore punk. hip-hop Children of Bodom==melodic death metal. power/speed metal. neo-classical Radiohead=alternative rock. art rock. electronic music think i might be close ....
Q:What types of ''Metal'' do you like best out of the following?
Q:What is the worst thing that happened to Metal?
Furry Handcuffs
Q:Who, or what band, started metal?
Alternative Metal is related to Nu Metal, there's no denying it. In fact many Alternative Metal bands were direct influences on Nu Metal, Faith No More, Primus, and Helmet to name a few Alt. Metal bands who were massive influences on Nu Metal. I'd say System of a Down is an example of an Alternative Metal band that sometimes get labelled as Nu Metal, although it could be argued that they're Nu Metal, their music is more in line with Alt. Metal, some of Mike Patton's work in Faith No More and Mr. Bungle is a huge influence on their music and it's more apparent than it is in most Nu Metal.
