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.


2,Main Features of the Ductile Iron Manhole Cover:

·High endurance

·High Strength

·Pressure Resistence



·Good visual effect

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:give me any metal quote U know ....?
Groove metal is one of my faves now. Stuff like In Flames and (I don't care what people say they fall into the groove metal catagory) SlipKnoT are good examples. Rap metal has lost alot of respect with douches like Linkin Park and such. Metal in general is good. Lamb of God, All That Remains, Disturbed(more hard rock now but the sickness WAS metal), Mudvayne, ect. All good bands and all Heavy. I love to beat up people who listen to Justin Bieber to LoG! LOLZ
Q:Good Scandinavian Metal Bands?
Grunge. I never liked hair metal.
Q:heavy metal?
in Sumter South Carolina all there is are ghetto people and their gay rap music. Then the white people are all rednecks and listen to hillbilly country $hit. My friends Ipods have the likes of Lil Wayne, Lady Gaga, Justin Bieber, Gucci Man, Lady Antebellum, Taylor Swift, and Katy Perry. When I ask my friend's, Do you have any Five Finger Death Punch or Avenged Sevenfold. they are like who is that. facepalm.
Q:what are some good pump up songs? i prefer metal?
If In the Nightside Eclipse ain't Black Metal then nothin' is.
Jimi Hendrix Ace Frehley Eric Clapton
Q:Is this nu-metal?
I have to go with Power metal just for the simple fact that I'm also not that familiar with Epic Metal ~ sorry :( Also, I have to admit that the whole 'genre' thing is getting really confusing to me. SPEED METAL / POWER METAL~ are they not the same? I'm only curious ~ it has never occured to me to categorize the music I like into specific genres...until recently ;) ;) ;)
Q:What happened to thrash metal?
You know the way that a car battery works? What you do there is that you draw electrons from metals to have be drawn through the circuit ionizing the metals and vice versa when recharging the battery. Now as compared to the other metals gold is less generous when it comes to giving off electrons as compared to the other metals so when you are doing the same as in a battery to that of whatever compound contains all of above mentioned metals you will have gold the last remaining nonionized metal. Just pour in any chloride solution or any halide and you will soak up the other metals. Rinse and repeat til you have only gold left. Easy as pie!
Q:Could you please define the term metal for me?
let M be the metal ans as sulfide has an oxidation state of -2, then the metal sulfide would have a chemical formula of MS. The reaction is shown below. 2MS (s) + 3O2 ----------> 2MO + 2SO2 We know that 1 mole of metal sulphide will produce one mole of metal oxide. Let x be the molar mass of the metal we have that the molar mass of the metal sulfide is x + 32. The molar mass of the metal oxide is x +16. The number of moles of metal sulphide is 1.2/(x +32) The number of moles of metal oxide is 0.728/(x+16) As one mole of metal sulfide forms one mole of metal oxide, then 1.2/(x+32) = 0.728/(x+16) = 1.2 (x+ 16) = 0.728 (x+ 32) = 1.2x + 19.2 = 0.728x + 23.296 0.472x = 4.096 x= 4.096/0.472= 8.678g/mol.
Q:Where can I get free metal?
the metal with higher specific heat capity will cause a more severe burn, as the property of the metal will absorb more heat energy and as well the difference between it and the object your burning will be much more different as the difference in energy level is also higher, lets say - boiling water ( 100 dregrees) . will not cause the same damage in burn as one made by a metal object with higher s.h.c - metal will obviously scar you in a way boiling water burns arent capable of achieving
Q:Which metal is crying?
well everyone will have a different opinion on the first two. personally i think Black Sabbath started the whole metal scene. there are MANY different types of metal, doom metal, death metal, glam metal, alternative metal, nu metal, goth metal, power, progressive, speed, thrash, dark, extreme, industrial, black metal.... the list goes on and on. youll have to become a metalhead to recognize the wide varieties, but if you want examples of certain bands from each genre, i suggest Wikipedia.
