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:twisted metal question?
Metal (so many different styles)
Q:What is your favourite subgenre of metal?
My fav metal band is Judas Priest. They're a British classic metal band. Check out Nighcrawler, Hell Patrol, and Living After Midnight (more of a rock song, but still great). There's also their song Metal Meltdown... That's a good one. Also, I love Iron Maiden... Another classic metal band!!! I'm sure you know who they are ;D A modern metal band... There's System of a Down, which is my fav. They're metal, so don't listen to somebody if they say they aren't... Just listen to their Toxicity CD. They're a progressive-rock/metal/doom-metal(psyche... genre. They rock pretty hard dude. Another modern one is Children of Bodem, which is more death metal than anything...
Q:Poll: Metal Music vs. Rap Music?
isn't it corpse paint and rawness some do it nicely some sound so undesirable that the 1st actual recording ever sounds greater advantageous its so wasteful. CC (new cd as reliable as ever), Morbid Angel (new album is arrive sometime quickly great!), and Carcass (who is conscious a pair of recent album yet they been traveling) they are death metallic. no longer many reliable Blackmetal out anymore like Darkthrone that's a could desire to as they been around continuously additionally the hurricane challenge Mutiilation is sorta nicely known yet constrained then I kinda pay attention to 3 new stuff like Kult Ov Azazel. i do no longer in elementary terms pay attention to easily metallic.
Q:what makes disturbed hard rock and not heavy metal?
a screamo fan
Q:How to Remember the properties of Metals and Non-Metals?
A good test by Albert Enstein to test for metal or non metal substance is to put the material under your armpit for 5 mins, if you removed it and it does not smell good, it means it's a metallic material
Q:Worse genre of metal?
Pop Singer all the way, Infact, as you can tell my fave Pop singer is on my avatar.
Q:plz help me!! how is metal made??
The moleculres are closer together and the molecules get excited and bounce around causing others near them to do the same. In a gas, the molecules do the same, they are just farther apart from one another.
Q:Favorite sub-genres of metal?
Q:Describe one chemical property of Group 1 metals...?
Love metal is not a genre Anything with Christian in it is not a genre, Christianity is a religion and has nothing to do with the style of the music Gothic thrash? I'd like to hear that. Same with gothic death, there exists fusions between the genres, but they shouldn't be considered own genres. Holy unblack metal: same as Christian metal; has to do with lyrical themes, not musical style What exactly is porncore? As for genres such as Blackened Deathly Thrash Metal and Industrial Gothic Death Metal, these are definitely not genres of their own, but rather fusions of different genres. The NWOBHM isn't exactly a genre, but a wave of music. New wave metal might refer to this, or bands from the NWOAHM (New wave of American heavy metal) Moshcore is a genre, better known as metallic hardcore. Ok, killcore maybe isn't. Alternative metal is, of course, a genre, but it's kinda weird because it just includes bands that don't fit in anywhere else. Pop metal=glam metal=hair metal. Traditional heavy metal refers to metal bands like Black Sabbath and Judas Priest, and also NWOBHM bands. Kinda means the same as just heavy metal, except it excludes newer bands playing in the same style. Norwegian black metal is the kind of black metal originated in Norway in the late 80's, but is now played by bands in many different countries, so calling Norwegian black metal a genre would be a little wrong. There is something called blackcore, but it's just a fusion between black metal and metalcore or hardcore. Same with doomcore and doom metal. Btw you forgot some pretty important genres, like folk metal, symphonic metal, groove metal and power metal. MAIN METAL GENRES Traditional/heavy metal Glam metal Thrash metal Power metal Progressive metal Gothic metal Symphonic metal Death metal Black metal Folk/viking metal Doom metal Groove metal Metalcore Nu/alt metal Grindcore The last three are often disputed in being metal or not.
Q:Is tin a transition metal?
not a big fan of metal but there is something more mellow which is kind of like progressive rock or i think there is even a genre called melodic metal? but anyway you may want to try bands like Opeth, dream theater, sonata arctic, stratovarius, angra, children of bodom etc etc etc. hope this helps
