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.

4FAQ:

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:Which metal subgenres have clean vocals?
Ibanez = Heavy Metal. I don't think they make much that isn't made to play metal, and when they do they make it pretty visible apparent.
Q:POLL: RAP or METAL ?!?!?
Nu Metal came off of Glam Metal and Grunge also came off of Glam Metal. They both have the same roots, so they do sound similar.
Q:England Heavy Metal Bands?
Black metal and death metal are two different things, and black metal doesn't necessarily have to bend your faith. You can listen to black metal and still believe in Jesus and all that stuff. Doesn't mean you have to worship Satan. Its just music. It shouldnt be a way of life.

Q:What is the difference between hair/glam metal and regular metal?
Bloodthirsty for Metal gave a great answer I guess I'll just sum up what I think: -It's more rapping with down-tuned guitars than actual metal -Most nu-metal bands just tried to copy Korn (the originators of this b@stard genre) rather than find their own sound, and hence most sound exactly the same -99% of all nu-metal lyrics revolve around teen angst, whining about how painful life is, more angst, and some more angst -Guitarists of this genre aren't particularly talented or innovative, in fact, I would say that they're completely untalented hacks: nu-metal guitar parts usually just consist of playing power chords on down-tuned guitars -Limp Bizkit, enough said
Q:Is metallica considered metal..?
Well think of it like a tree... there are the main genre branches and then there are other genres that branch off from it. so yes you are right but also at the same time your wrong. It all depends how you look at it. Not that I am an expert, ha, far from it. Screamo in particular branched off mainly from hardcore punk if I am not mistaken, Thrash is an extreme subgenre of heavy metal that is characterized by its fast tempo and aggression. Power metal is a style of heavy metal music combining characteristics of traditional metal with thrash metal or speed metal. Black metal is an extreme subgenre of heavy metal. It often employs fast tempos, shrieked vocals, highly distorted guitars played with tremolo picking, double-kick drumming, and unconventional song structure.
