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:Do you respect heavy metal music?
My favorite death metal bands as of now are The Black Dahlia Murder, Fleshgod Apocalypse, Abysmal Dawn, and Bloodbath
Q:Why is Magnesium a metal?
I think the whole if it ain't metal, it's crap thing is complete bullshit. To say you love music and to call yourself a musician means you should appreciate and respect all forms of music.
Q:Why are metals are reacted with 3 different substances (water/ steam/ acid) ?
who or what is a metal slug
Q:Metal fans?
European Metal owns, especially British Metal.
Q:Examples of metal?
All metals can be classed as either ferrous or non ferrous. Ferrous metals contain iron. They may have small amounts of other metals or other elements added, to give any required properties. Also, ferrous metals are magnetic and give little resistance to corrosion. e.g steel Non-Ferrous Metals are metals which do not contain any iron. They are not magnetic and are usually more resistant to corrosion than ferrous metals. e.g aluminium, copper, lead. zinc and tin.
Q:What are your favorite metal bands in each genre?
They are a metal band, just an increasingly worse and worse one Yes, they did make Thrash riffs. This is heard on Scream Aim Fire and Waking The Demon among some other songs. (To correct the guy who said they didn't) But why is BFMV getting worse and worse? 1st 2 albums were good, 3rd ok, 1st 2 songs released from the upcoming 4th album are absolutely dissapointing....... what's going on with them really? Wtf?
Q:Black or Death metal?
a kid ive come to trust about matters such as these says that nu metal is any metal where the singer goes from screaming to singing or talking or anything not screaming
Q:American or Non-American Metal?
Q:Good metal............?
it's halogens... can't be alkali metals or transition metals because group 2a metals and alkali metals and transition metals all usually have positive charges, so they don't attract to each other, and noble gases are mostly unreactive.
Q:Why is metal always cold?
the only good heavy metal band is Metallica.
