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:What are non-metal and metal oxides?
I have to reiterate since you did mention Thrash for the Extreme side, It too has it's roots from Hardcore Punk scene. Thrash is really just Thrashcore in todays genre sense. If the music is good listen to it. Labels mean squat. Screamo should never be added to a list of Metal genres, any REAL Metalhead would know that
Q:metal gear solid 4?
I never said it wasnt metal, I just said it's not good. I can barely find any good metalcore bands. Many sound way too emo also.
Q:need help bad unknown metal prob?
Metallica-Thrash metal Static-x-nu metal Nightwish-power metal Katatonia-doom metal with clear vocals Iron maiden-new wave british heavy metal type O negative-doom Dream Theater-progressive metal lacuna coil
Q:How many parts does Metal Gear Solid has?
Heavy metal definetly. But some alternative is okay. Q101 is the greatest radio station ever :P
Q:Where are my METAL HEADS!?
Kind of splitting hairs here aren't we?
Q:Are metals crystalline?
Pretty sure metal is more head-banging. Take 80's ROCK for example. How many of those songs were head-banging like some Nickleback songs can be? Almost none. So metal is hardcore rock or rock is a soft metal
Q:Clear Vocal Metal Bands?
Metal + hip hop influences + downtuned guitars Did you seriously not know? Nu Was THE mainstream rock of the late 90's.
Q:Do power metal and progressive metal count as extreme metal?
i dont
Q:Whats the difference between Death Metal, Melodic Death Metal, Deathcore, Doom Metal and Black Metal?
Because many people want to try to lie to themselves and say their bands are metal. Like Slipknot and Disturbed. Nu-Metal is not real metal. I can also guarantee that a lot of people who call bands like that metal are teens.
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.
