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 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:Alternative Metal bands?
I enjoy every sub-genre of Metal. Black Metal, Prog Metal, Tech Death, Thrash Metal, Power Metal, Folk Metal, Metalcore, you name it. I enjoy Hair Metal. My favorite Hair Metal bands include, but are not limited to, Guns N Roses, Mr. Big, Quiet Riot, Twisted Sister, Motley Crue, Ratt, Skid Row, Europe, and old Def Leppard. I think the main reason that most metalheads dislike Hair Metal is because it's a lot less heavy than other Metal and gets more attention than it deserves. I can't say I disagree, but personally I enjoy Hair Metal because it's catchy, upbeat, and requires talent to play (listen to Mr. Big if you don't believe me. You can't deny that Mr. Big is awesome).
Q:Good Japanese metal songs?
Basically, metals are elements that can't hold onto their electrons tightly. I think this is because as you go down the periodic table and atoms get larger, elements get less electronegative, which is a measure of the ability of an element to hang onto its electrons. The most electronegative element is Fluorine. Moving to the left or down will just make them less so, and more like metals.
Q:What to you is not real metal?
Ska! Specials! Police! Skavoovie! o_o
Q:10 points: What is Neo-classical metal?
nicely i can in basic terms answer the 6th one it would could be saved in petroleum to maintain it removed from moisture...because of the fact it wud react with water and whilst it reacts it would reason dorobium(g)
Q:Facts about Transition metals?
Their guitar aren't distorted enough to be metal.
Q:Difference between Grunge and Nu metal?
You're discarding the entire genre because of the bullsh** lyrics some bands write. That just shows that you're an idiot and couldn't be bothered listening to metal properly. All metal bands members play an instrument, so they know something about music. Just because some singers are too inarticulate to write good lyrics doesn't mean they can't play guitar brilliantly. Ps: Nirvana suck NP: Opeth - A Fair Judgement
Q:Would you consider Korn to be metal?
Probably because they're metalcore.. some people don't always know the difference but lol at death metal, that's just dumb
Q:Whats the diff. between the DDR dance mat and the DDR metal dance pad?
Well, since 2000, most of the new metal bands have been FALSE metal bands. These are REAL metal bands that have released albums since 2000 and my favorite albums from each one: Lamb Of God-Sacrament (Groove Metal) Children of Bodom-Follow the Reaper (Melodic Death Metal) Arch Enemy-Doomsday Machine (Melodic Death Metal) Amon Amarth-With Oden on Our Side (Viking Death Metal) Vader-Revelations (Death Metal) Behemoth-Demigod (Blackened Death Metal) Demonoid-Riders of the Apocalypse (Death Metal) Bloodbath-Nightmares Made Flesh (Death Metal) DETHKLOK-The Dethalbum (Melodic Death Metal) Dimmu Borgir-Death Cult Armaggedon (Symphonic Black Metal) Five Finger Death Punch-The Way of the Fist (Groove Metal)
Q:Metals, Non-metals and metalloids question!?
Most metals exist in nature as chemical compounds salts. Iron exists as oxides and sulfides usually. Copper may exist as metal but most of it in the form of salts. Gold, of course, exists mostly as the metal.
Q:So what do metal-heads consider metal?
My favorite would be Morbid Angel.
