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:Good metal bands??? :)?
semiconductors - metal halogens - nonmetal noble gases - nonmetal Semiconductors are used for the transference of energy. They can be found in things such as solar panels. Halogens are the elements like chlorine and bromine and are the elements in the column second to the right. The noble gases are... clearly not metal... they're gases... it's in the name!
Q:Whats better metal or hard rock???
I always thought it was the odd song structure that made something progressive, as in it progresses as it goes, where as regular stuff has a common structure that it follows, and the song doesn't really change that much before the end, for example old Opeth songs almost never repeated the same riff that occurred earlier in the song.
Q:Old Metal vs New Metal?
Heavy Metal (20th Century) - Black Sabbath, Judas Priest Heavy Metal (All Time) - Metallica, Iron Maiden Groove Metal - Pantera, Sepultura Industrial Metal - Nine Inch Nails, Faith No More Thrash Metal (I think that's what you meant) - Trivium, Metallica Progressive Metal - Dream Theater, Kamelot Speed Metal - Gothic Metal - HIM Symphonic Metal - Kamelot, Epica Power Metal - Scar Symmetry, Solution .45 Metalcore - The Devil Wears Prada, Avenged Sevenfold/August Burns Red Nu Metal - It's kinda' hard picking bands for this because so many bands cover multiple genres but I did the best I could.
Q:could someone who likes metal explain this?
A ferrous metal is a metal that has been aggravated to the point of fury. They are best represented by the chemical equation: metal + trollface -> ferrous metal A good way to produce them is to combine older memes and internet forums, such as 4chan or reddit.
Q:Reactions of acids with metals?
sounds like a question I would have expected Heavy Metal Jesus to ask!
Q:how is nu-metal and metalcore the most hated metal sub-genre?
1. Slayer 2. Megadeth 3. Cannibal Corpse 4. Mastodon 5. Black Sabbath
Q:what is melodic metal?
Florida is where Death Metal originated and is still strong.
Q:Whats the difference between power metal and traditional heavy metal?
I'd like to say firstly: AC/DC, KISS and Led Zeppelin aren't metal, hard rock/ rock. Metal is the genre. Then there are the subgenres that are classified under metal for example: Turisas, Equilibrium, Korpiklaani, Eluvietie, Finntroll, and Ensiferum are all folk-metal Devildriver, Wintersun, Insomnium, and Children of Bodom are Melodic death metal. those are just a few band examples of sub genres. other genres include, death, viking, power, black, speed, sludge, doom, and progressive. Now a lot of bands that come out now are either Deathcore or metalcore. Basically its the roots of hardcore punk (the infamous screaming and fast playing) with death metal (deatchore) or metal (metalcore) influences. It's not true metal, but it has a metal sound. Bands like Suicide Silence, The Black Dahlia Murder (though they have some melo death influence), With Blood Comes Cleansing, Suffokate, etc etc are deathcore. Bands like As I Lay Dying for an example is metalcore. I hope this helped a little :)
Q:Why do people not like death metal!?
Progressive, but really depends on the band. Symphonic. Power. Heavy Metal. Thrash, Industrial and Sludge use what I call aggressive/harsh vocals - clean but shouting a lot. MDM and Metalcore often use a mix of clean and screams. Nu Metal use clean, aggressive, screams, growls and rapping. Post-Grunge and Alternative Metal. Doom Metal, again depends on the band. Bands with clean vocals from each genre I mentioned; Dream Theatre After Forever Blind Guardian Led Zeppelin Metallica Ministry Mastodon In Flames Bullet for My Valentine Sevendust Alter Bridge A Perfect Circle Paradise Lost
Q:what is attracted to a magnet but not a metal detector?
I don't know any screamo bands but here are some Metal/Metalcore bands Disturbed Black Sabbath Iron Maiden Metallica Atreyu Devildriver Falling in Reverse Escape the Fate Black Veil Brides Korn Slipknot Dragonforce Children of Bodom System of a Down Papa Roach A Day to Remember Megadeth Anthrax Pantera Slayer Stone Sour Drowning Pool Alice in Chains As the world fades Bad Religion
