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:Whats next for metal?
Metals like iron, potassium, zinc, and magnesium are found in the human bloodstream and are needed or else we'd all be dead.
Q:How many parts does Metal Gear Solid has?
I prefer to like underground metal to Mainstream rock and I good Reason why for example: In my home town in october The band Random hand are comming to play the ticket about £6(in dollars about $11) cheap as chips, they wont sell out, becasue not many people are there Ill be able to meet them after the show and there merchandise isnt that expensive. However In december Slipknot, A very Mainstream band, are comming to play in my home town. The Tickets are £30(about $50 something dollars) however I think they have sold out and are going very expensive on OKorder, I wont be able to meet them cause of the people and their merchandise will be very expensive. I do like a band for it's music but I just don't like underground bands to get that famous if you get my point. And alot of rock is Mainstream.
Q:HELP me list 5 properties each for metals & non-metals?
Every thing in this world tries to gain stability metals also lose electrons to gain stability by attaining the configuration of nearest noble gas.Metals usually have 1,2 or 3 electrons in their outer most shells so it is difficult for them to gain electrons( for completing their outer most shells),as compared to lose elctrons.Thats why metals lose electron.
Q:what are some BADASS METAL SONGS???
Type O Negative Spineshank Stone Sour Slipknot Tool Static-X Ministry Ill Nino Rammstein A Perfect Circle Korn Marilyn Manson The Deftones Chevelle Rob Zombie Lacuna Coil Nine Inch Nails Overkill
Q:extracting alkali metals?
Basically. Black Metal is largely based on satan - See Mayhem, Dark Funeral, Dark Throne. Death Metal is based on Death. - See Deicide, or Morbid Angel. Melodic Death is death but mixed into classical music or other melodic rhymes - See Opeth or In Flames Power Metal is music from the 80s, very fast and usually up beat. See Extreme, and newer, Dragonforce. Progressive Metal is more, unusual. Best thing i can advise on that is someone like Tool, or even Ghost Reveries from Opeth. Gore Metal is based on brutality, mutilation, murder and rape. See Cannibal Corpse, Decapitated, Incision or Exhumed. Industrial sounds electric, as if played by machines, check out Fear Factory or Static X. Heavy Metal is the basic from the 80s, just heavy, see Judas Priest, Iron Maiden, Manowar. Thrash Metal is similar to heavy metal but faster and usually with more technical solo's. See Metallica, Slayer or Anthrax. Doom Metal is slow going, not much happens, see My Dying Bride. Gothic metal normally means Operatic vocals, check out Nightwish, Leaves Eyes, After Forever or others like that. Folk Metal is based main on Folklore, but i can't think of any specific bands, though you could put Arkham in there, who are H.P. Lovecraftian Metal. Viking Metal is just music based on Ancient Norsk. Most Black Metal bands include parts. The BEST kind of metal at the moment though, appears to only have 1 band, and thats pirate metal!!!! Check out Turisas for that! Hope this helped :) But to me, metal is metal, its all good =D
Q:What makes a band metal...?
Don't use plural terms when you're referring to metal. I thought you were asking a science question for a second, haha. Its THRASH not TRASH by the way. Unless you're a fan of black and death metal, they're both gonna sound the same to you.
Q:metal question?
depends on the weight of the metal roofing. I had aluminum shingles installed on my roof over the original shingles. but the total weight of the aluminum shingles is 400 lbs. spread out over the whole roof. so ther is very little danger if overweight.
Q:Is metallica considered metal..?
Q:is black metal/death metal satanic?
Some that I can think of off the top of my head would be: Death Thrash Gothic Symphonic Doom Glam Power Speed Stoner Extreme Folk Alternative Black Unblack Experimental Progressive Groove Rap Nu Neo-Clsssical Funk Metalcore Deathcore Grindcore Avante-Garde Drone Industrial Viking Sludge
Q:easy metal accoustic songs on guitar?
It means that Metal B is denser than metal A so it takes longer to warm.
