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 is the strongest metal?
I'm a guy. And no. Just no.
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:Can i stain metal???????
Metal as in heavy metal? The only things I can twell you without specifics is that metal evolved from blues and punk music Death metal vocals evolved from thrash metal vocals And Nu metal is not metal, it is modern hard rock.
Q:What do you think is the best era of metal?
Normal is defined by the society we are born into. There is no such thing as normal, because society changes and evolves over time. So you can love metal all you want, I do.m/
Q:The Best Metal Song of All time?
The answer is a combination of the above: fresh metal surfaces absorb light and immediately re-radiate the photons. If the metal is inert, like gold, it stays nice and shiny, but most metals react with air or with sulfur compounds in the air to form a surface coating of oxides or sufides. Silver tarnishes, iron rusts, pennies get dark and dull. Remove the coating, or cut into the metal, and you expose a fresh, shiny surface.
Q:What subgenre of heavy metal plays southern country sounding music besides groove metal?
Q:What is metal? [20 characters]?
Personally, My fave is Bodies by Drowning Pool, there's also Slipknot, Serj Tankian, System of a Down, Linkin Park, Nine Inch Nails, and def some Metallica (mainly older stuff, but you might like the newer stuff too). Just find some older CDs at Co-op or some other store like that, where you can buy them used instead of spending too much green on something you don't like.
Q:Why is Screamo not Metal?

Q:How to determin if an unknowen element is a metal, non-metal or metalloid?
I prefer thrash metal. To me metal should be heavy. I'm not saying that metal bands can't be melodic; there are some very good melodic bands out there, some of which I like very much. And a bit of melody can make a welcome change from all that brutality. But gebnerally I like my metal hard and heavy, and therefore I like thrash better, especially Slayer. Although black metal is my favourite.
