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:Why is Magnesium a metal?
i find it stupid. i personally like almost any genre between punk rock and death metal. its because metal is so expansive and has so many sub genres that their like COMPLETELY different genres, so fans of different metal sub genres compare each other like a jazz fan to a country fan or something. the beauty of metal is that it contains so many different elements and can still be the same thing. a shame that everyone has to forget that everyone is entitled to their own opinion.
Q:What are your favorite sub-genres of metal?
Heavy metal is not a bad enemy anyway. I play for an all-girls-in-bikinis rock band called Charlotte Murphy as the lead guitarist and backing vocalist.
Q:name of iron(metal)which doesn't contain carbon?
Who says metal is dead? Sure, mainstream metal has gotten terrible and shot itself in the foot since the 90's (Metallica post-black album) but heavy metal is alive and well. Only problem is we have so many mental genres that people jumble together in this musical clusterfu**. We have Bullet For My Valentine fans who breathe My Chemical Romance and Led Zeppelin in the same sentence.
Q:how do you judge if an element is a metal or non-metal?
Disturbed Evanesance Lacuna Coil Saliva Slipknot and heaps others.
Q:Define Metals, Metalloids, and Non-Metals...need answers fast?
In all honesty I think it has a lot to do with the vocals and some of the instrumentation. A lot of the groups that are considered nu-metal tend to have cleaner vocals. By clean I mean they sing a lot more than traditional metal groups. Nu-metal groups with the exception of maybe Slipknot because of Jordison and his tempo usually aren't quite as fast-paced and don't use as much double bass either. Those are really the only things that stick out between them. However as someone mentioned genre grouping is subjective and there is no clear cut answer. I just see Nu-metal as a intermediate between hard rock and metal. The bands typically placed in this category are badass though (i.e. Slipknot, Korn, Disturbed, SOAD).
Q:death or black metal????????????????????????????
Q:England Heavy Metal Bands?
Black metal and death metal are two different things, and black metal doesn't necessarily have to bend your faith. You can listen to black metal and still believe in Jesus and all that stuff. Doesn't mean you have to worship Satan. Its just music. It shouldnt be a way of life.
Q:What some people call metal..?
You're an idiot.
Q:what metal is spoon/forks usually made of?
Glam metal, most definitely. Nu-metal started off as an experiment with bending the rules of metal and integrating elements of hip hop and other genres, while glam metal was pretty much just invented as a radio-friendly version of true metal from the start. In other words, nu-metal wasn't originally invented to be commercially viable, while glam metal was.
Q:What is the hardest type of metal music?
metal gear solid 3d all the way broskee ;D
