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:any good melodic metal ?
Heavy metal, TRUE metal would be bands like Judas Priest, Black Sabbath, Ozzy Osbourne, Deep Purple, etc. BFMV is more of a Metalcore band. Bring me the horizon is Deathcore, (death Metal/Metalcore/crap) The stuff you are listening to isn't heavy metal, Tool, and Mastodon might be a different style of sub genre though. The rest is just screamo crap. Death Metal is music that has fast drums and guitar, high distortion guitar, and usually really rough low growling/screaming vocals.
Q:is chimaira hardcore or metal?
Define nu metal ? if you mean all the pretty boy bands that took a different direction and market, no I cant stand that stuff. But what nu metal I like Mushroomhead, and they've been around for 14 years, so would they be considered nu metal ? theres alot of good bands out there that have a hard sound I dont like lumping bands into a grunge, nu metal whatever label. You have to admit though alot of bands sound too much alike especially the newer stuff I like bands that have their own sound, as to why people hate it ? all about your personal preference in music I hate Rap and alot of the new Country, then again I hated alot of the pretty boy hair bands see another label like Poison Warrant...
Q:What are some good Metal bands?
I'm sorry, but you asked the question and then you concluded it yourself. What else do you want? They 'shred' I guess you haven't heard 'Sulfur' 'Psychosocial' 'Pulse of the Maggots' or a lot of their newer songs, cuz they do have a lot of guitar going on between Mick and James. (Since you probably aren't a big fan...) And, what, they don't have high screams? I never knew it was a specification of metal to be able to scream really high-pitched. Corey can growl and he can definitely scream, have you not heard any of their music? Especially the album Iowa or their self-titled? Check out the song 'Scream' for God's sake. Or 'Get This' 'Spit it Out' 'Surfacing' 'Eyeless' 'People=****' or 'I Am Hated' if you want some good examples of what Corey can do. They are in some cases considered Heavy Metal but they are definitely Nu-Metal. In fact, they stand as founders of the sub-genre itself. You do know metal has many different sub-genres, right?
Q:compare metal and non metal?
Christian Black Metal or sometimes called simply white metal was really created just to be a counter to Satanic Black Metal bands. Most likely by Christians who liked the sound of Black Metal but not the message. As for Pagan black metal, I imagine the same only not so much a counter against Satanic black metal (Pagans are very accepting of other religions) but probably as a way to express their religion and culture through black metal. Don't quote me on that last paragraph.
I think metal is a genre of rock and if they separate into metal and rock they would also have to make progressive rock and other genres separate.
Q:Why are Alkali Metals so reactive?
Metal Hydroxide
Q:Is adamantium a real metal?
Here are my top 10 metal/rock bands. I included what type of metal/rock they are and my favorite album by them. 10. Disturbed (Down With the Sickness) Nu Metal/Heavy Metal 9. Godsmack (Faceless) Alternative Metal/Hard Rock 8. Guns N' Roses (Appetite for Destruction) Heavy Metal/Hard Rock 7. Staind (Dysfunction) Nu Metal/Alternative Metal 6. Iron Maiden (Killers) Heavy Metal 5. Seether (Karma and Effect) Post-grunge/Hard Rock/Alternative Metal 4. System of a Down (System of a Down) Progressive Metal 3. Metallica (Ride the Lightning) Thrash Metal/Heavy Metal 2. Machine Head (Burn My Eyes) Thrash Metal 1. Korn (Korn) Nu Metal/Alternative Metal I realize not all are modern, but alot of the modern stuff I listen to is metal core and death metal.
Q:How do you reconize metal genres?
Where did you find that sick question? Did you leave anything out? There are many, many metal oxides and they expect you to find the percentage of the metal in every one of them and go through them all while hoping to find the one that has specifically 74.2% of the metal in it. Was there a specific metal named instead of just metal?
Q:cowboy/western inspired metal?
Nightwish...power metal
Q:Who killed the metal?????
Metal Gear Solid HD will keep you entertained for months, being that each game is pretty long. However, if you're an online player, go for Twisted Metal, as the online on it is pretty fun (or so I heard).
