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:Your least favorite metal sub genres?
I fully disagree with that statement. Hair metal is the one genre of metal I really don't like other than a few bands and I love Thrash.
Q:when metal is removed from metal oxide?
The typical death metal fan is a high-school dropout with anger management issues, an addiction to meth, and really lousy taste in music. Those guys can have that crap, I'll stick with bands like System Of A Down and Metallica, bands that actually have talent. And Christian death metal? That's a contradiction in terms. Christianity is all about celebrating one's spiritual rebirth and eternal salvation, therefore anything with the word death in it really has no place in Christian doctrine.
Q:POLL: Metal or Rap music?
GnR isn't hard rock, sorry. They were part of a huge genre that lated almost a decade, and while that rock is considered harder than the music you hear today it's not the same thing as ACTUAL hard rock Hair metal's not a bad thing, it just has an un-just bad connotation.
Q:Metal Chat?
i love metal. I live, breathe, and dream metal. me personally though i like the good old fashion old school death metal like death, old school. dying fetus, Nile immolation, krisiun, carcass. that stuff. but i still love progressive death metal, folk metal, original technical death metal not this faceless ****. I like heavy metal and melodic death metal as well. sorry if my answer is scattered im a little tired. lol
