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:Name Some Good Metal bands?
Favorite metal band is Dream Theater. For song, it's a toss-up between Home and The Glass Prison.
Q:Good Scandinavian Metal Bands?
For me i choose the same as you, Hair metal. I live my teenager life when the hair metal music really exploding the world. Their music are so amazing for me, they bring a genre that really make me love them so very much. Their music is a brand new kind of music, their sound, their lyrics, their attitude, their dressing and their artwork for their cover, all are so unique, very unique, so when you see their cover in their cd then you will know that their music must be Hair metal. Grunge music is also cool, nice riff and also have a unique sound, so seattle. But their music is so temporary, their music can't be forever. They ever blow the world once but that's never make me love them as much as hair metal. Hair metal is still the best for me until now. Hail to you to love it.
Q:What are some of the advantages of recycling metal?
A metal replaces another metal from it's compound if this metal is more reactive than the one present in the metallic compound. The reaction of a metal with a metal compound results in a new metal compound, with the original metal present in the compound replaced by the reactant metal, IF AND ONLY IF this metal lies above the metal present in the metallic compound in the reactivity series. This can be written as: If a metal say metal1 reacts with a compound of another metal, say metal 2, then the reaction can be written as: Metal1
Q:Identify the unknown amphoteric metal?
Progressive metal (sometimes shortened to prog metal) is a subgenre of heavy metal, which blends the powerful, guitar-driven sound of metal with the complex compositional structures, odd time signatures, and intricate instrumental playing of progressive rock. Many progressive metal bands are also influenced by jazz fusion and classical music. Like progressive rock songs, progressive metal songs are typically much longer than standard metal songs, and are often thematically linked in concept albums. I believe that kamelot is power, but i might be wrong since i don't really listen to them :)

Heavy- Judas Priest, Black Sabbath, Iron Maiden Hard Rock- AC/DC, T. Rex, Def Leppard Alternative Metal- Deftones, Tool, Mr. bungle Thrash Metal- Metallica, Slayer, Megadeth Industrial Metal- Ministry, KMFDM, Nine Inch Nails Metalcore- Converge, Botch, Cave In Hardcore Punk- Black Flag, Bad Brains, Cro-Mags Deathcore- The Red Chord, The Acacia Strain, Suicide Silence Nu Metal- KoRn, Slipknot, Linkin Park Death Metal- Cannibal Corpse, Death, Atheist Post-Hardcore- Fugazi, Quicksand, Refused Gothic Metal- Type O Negative, My Dying Bride, Tristania Black Metal- Burzum, Bathory, Mayhem
