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:Extreme Metal Fans: Do you like Power Metal?
metal gear solid is a game with a very intense and fun story line. i would suggest getting the first game. But out of those I would go for metal gear rising as the metal gear solids and metal gears have a bit of a different story. And there are less metal gear games than there are metal gear solids.
Q:What are non-metal and metal oxides?

Q:what is working of a metal?
Black Metal, Blackened Death Metal
Q:Difference between all the metal genres?
I don't understand. it just dont seem right. Yes, it's okay I guess?; i mean, ur question sounds too vague to make any sense; Anyway, I prefer thrash, power, and death, not black. Because I'm more of a shred/technical dude, and black metal bands rarely play solos, plus they sometimes want to play poorly on purpose to be more trve(with the exception of blackened death, symphonic black, etc.)
Q:Favorite sub-genres of metal?
Q:Please suggest me some good death metal songs?
find a better periodic table and it will tell you
Q:what are some good metal bands?
metals are found in ores. these ore are comprised of other various elements ( like oxygen, sulfur, etc). for the metal extraction, the ore needs to be crushed, then frothed, then left to react with dilute acid, then smelted . ores can be found on the surface of the earths crust or deep in the earths crust. their is also a high percentage of iron in the mantle, outer core and inner core of the earth.
Q:What is the difference between varying types of metal?
Every decade has a watered down commercial version of metal that the community rejects but finds enormous success with teenagers who desperately want to be metal but don't want to have to learn to play or listen to it. It was the hair bands ages ago, grunge, nu metal, now the whatever-core kids are the next in line. It will pass soon enough and they'll be forgotten.
