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

We have organized several common questions for our clients,may 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:What is your favorite band....[[[metal]]]?
Aluminium metal combines with the oxygen from the air on heating to form aluminium oxide. The reaction can be represented using a balanced equation as 4 Al (s) + 3O2(g) => 2Al2O3(s)
Q:POLL: Heavy Metal or Rap?
1 luster- metals have luster also known as the shinyness of the element 2 malleable- metals are malleable or the ability to be flatened without shatering (to test hit with a nail and hammer and if there a dent it metal if it shaters it not) 3 conductivity- metals conduct electricity and non metals dont, and a metaloid can do eather 4 heat- metals conduct heat beter so if it conducts heat its a metal (to test put hlaf of element into ice cold or hot water and if u can feal the heat or coldness when holding it outside the water it a metal if not its a nonmetal or metalloid can do both) a metaloid could have some of each proporties so its best to do all tests and if it has properties of nonmetals and metals its a metaloid
Q:im black and i love heavy metal, death metal, black metal, goth metal.are there other blacks who love metal?
a lot of bands use Drop B tuning like Parkway Drive, BMTH, Ect i know they are metalcore A Day to Remember use tunings in Drop C aswell as Drop B
Q:i need soem good metal bands now?
do you know anything about valence band, conduction band, band gaps etc? may be you can search these terms in google. Metals do not carry more electrons than protons. metal electrons are loosely bound cause they have lower electron affinity, and their band gap is smaller, so conduction band and valence band is close to each other.
Q:Does Deathcore/Metalcore count as Metal?
Well maybe a naked woman?
Q:difference between types of metal?
In Flames  Death  Opeth  Insomnium  Dark Tranquillity  Machine Head  Meshuggah  Agalloch  Ensiferum  Equilibrium  Devin Townsed  Decapitated  Black Sabbath  Dio  Candlemass  Electric Wizard  Judas Priest  Metallica  Megadeth  Slayer  Kreator  Overkill  Exodus  Nile  Dream Theater  Tool  Strapping Young Lad  Scar Symmetry  Amon Amarth  Bathory  Venom  Celtic Frost Gojira Obscura Iced Earth Iron Maiden Anthrax Omnium Gatherum Children of Bodom Testament Kalmah Symphony X Katatonia Accept Motörhead At The Gates Carcass Morbid Angel Decide Cynic Atheist Sepultura  Kataklysm Vader High on Fire Sleep Burzum Wolves in the Throne Room Isis HellHammer Dark Throne Alcest Behemoth Dimmu Borgir Eluveitie Diamond Head Saxon King Diamond Merciful Fate Pantera Pentagram  Entombed Obituary Pestilence Necrophagist  Belphegor Voyager Alchemist Fates Warning Nevermore Queensrÿche Animals As Leaders Fear Factory Between the Buried and Me Mastodon Porcupine Tree Pagan's Mind Born of Osiris The Faceless While Heaven Wept Baroness Sodom Destruction Death Angel Dark Angel Ne Obliviscaris
Q:Metal Gear Solid Series Confusion?
metals are malleable (they can be formed into wires. In other words, they bend, they don't break) metals conduct electricity (the best conductor is silver, followed by copper) metals conduct heat metals are shiny because of their sea of mobile electrons
Q:Metal songs with both death metal growls and epic/power-metal style clean vocals at the same time?
Metal is a normal constituent of soil because many rocks contain metals and soil is weathered rock. Higher concentrations of heavy metals, like copper and arsenic for example, can be found in industrial or heavy traffic areas because of fine particles of metal emited from factories and car exhaust, as well as rubbing off of tires and corroding/breaking down of waste and trash.
Q:What are some good Metal bands?
Being from Des Moines I would have to say they definitely push towards a new direction after Iowa came out. In subliminal verses they toned some songs while shredded others Its just how they evolved as a band. In sublimial verses the whole idea was that it was progressing into a newer sound. And it told the fans that hey were changing some s hit, but were going to keep our s hit our s hit and with Blister Exits he basically said i wont let you get away without hearing what i had to say , basically an untone for the whole cd and band in a changing form. you gotta look at them not only as music you push play but the art of a human Duality so i hope that answered some questions or confused the s hit out of ya. eighter way thanks for question.
Q:rock & metal?
Obituary, Bolt Thrower, Cynic, Morbid Angel, Death, Dismember, Dissection, Vader, Dark Funeral, Dark Tranquillity, Hypocrisy Are some of the real heavy ones. Some older bands... Dio, Black Sabbath, Helloween, Magnum, Saxon, Dokken, Megadeth, Metallica, Judas Priest, WASP, Iron Maiden, Motörhead, Accept, Ratt, Mötley Crue, Guns 'n' Roses, Van Halen, Kiss, Europe, Dare, Tygers Of Pan Tang, Diamond Head, Trash, Mercyful Fate. More heavier older bands: Slayer, Exodus, Pentagram, Sodom, Saint Vitus, Kreator, Death Angel... Ugh there are a billion bands. These should give you something of a metal inspiration. Good luck with your metal experience. Love// Kriss.
