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.

·High endurance

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:How does Metal Music affect me?
Blind Guardian (power metal) Running Wild (power metal) Bathory (black metal) W.A.S.P (traditional metal) Kreator (thrash metal) Mercyful Fate (traditional metal) Overkill (thrash metal) Dark Angel (thrash metal) Those are some good old metal bands, here are some good news ones: White Wizzard (traditional metal) Holy Grail (traditional metal) Eliminator (thrash metal) Warbringer (thrash metal) Skull Fist (traditional metal)
Q:What are some good Death Metal/Heavy Metal songs?
Dude ur forgeting Rammstein.
Q:Favorite sub-genres of metal?
Q:TF2: Is refined metal worth something?
it has a bit to do with the guitar technique used. Lyrics for black metal are also very pagan, very earthy about snow on trees in forests and ****. It is confusing as some Devin Townsend (for example) songs have a lot of black metal elements to them and if he wore corpsepaint he'd probably be labelled as such yet he has never quite rightly been known as black metal. Venom came up with the title black metal but yes many of their songs are not what these days is known as BM.
Q:is symphonic black metal Real black metal?
Black ,more atmospheric.
Q:Is there a difference between progressive metal and technical metal?
As free atoms, metals have exactly the same number of electrons as protons. In compounds, they lose electrons and become positive ions. As metals, the outer ring electrons can roam around throughout the metal and that is why they conduct electricity.
