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:Is heavy metal bad.......................?
I would estimate that it's probably New York - New York being one of the main origins, if not THE main origin, of the Hardcore music scene in the US. Other areas/cities I would think that have been highly influential in the US or have very active metal music scenes: San Diego, CA Atlanta, GA Detroit, MI St. Paul, MN
Q:Is base metal real silver?
Death Metal
Q:Favorite category/ sub-category of METAL?!?
Metals are soluble in water. You can buy vitamin fortified water which contains iron zinc and other metals too.
Q:Metal Gear for Wii?
We are a mining operation. We mine for copper and out t comes, tonnes and tonnes of copper bearing rock. But our customers do not want that. They cannot use it. They want pure metallic copper to make into pipes or whatever else copper gets used for. We need a pure plate and onto this we can deposit the copper atoms from our mining operation. We get rid of all the other stuff we don't want. But we must use pure copper to keep the copper pure in our end product, which is much greater than the bit of pure copper we started off with. Think of it like a computer is. Rubbish in, rubbish out. Nobody wants to pay copper prices for impure product.
Q:what are the topics covered in metal working.?
When you can't go forward,you must go back to the roots and reinvent them.I'd rather have a new Sabbath or Priest type metal band than some nu metal,psuedo metal crap.Metal has always been about the feeling,the rush,the excitement,the power.That has nothing to do with speed or technicality.Metal is famous for being extremely tight.if a band could incorporate that tight but loose feel of a Stones or Zeppelin into pure metal,that would be a good step.
Q:are there any blue metals?
Most of these are a bit old, but these are some of the heavy metal bands I listen to: in flames carcass amon amarth death morbid angel nile cradle of filth vader behemoth novembers doom deicide (old) testament slayer pantera overkill life of agony type o negative danzig judas priest iron maiden savatage shadows fall vision of disorder suicidal tendencies
Q:What music genera dose metal most fight against? (apply s no non metal fans too)?
Thankyou all for your replies and opinions.
Q:Reactions of acids with metals?
There are some good, interesting bands, but a lot of it is just poser garbage. Far more marketing than any * true * inherent evil. Most of the fresh-faced suburban adherents wouldn't know what to do if they confronted real evil. They'd probably equate evil with daddy's BMW being in the shop.
Q:Can the sun burn metal?
the metal gear series started all the way back on a little known system called the MSX here are a couple of links that give the game history and even a fictional timeline of what supposedly was going on in the world.
Q:Name as a Metal, nonmetal, or Metalloids?
Wow, I can't believe someone just called Pantera wannabe metal. I hate them, but they're metal. If I really wanna go into what Heavy Metal is/was as a genre, the bands I think of are Metallica, Megadeth, Iron Maiden, Pantera. But I also believe that 'Heavy Metal' is gone now and now we have all the tons of subgenres of metal. Slipknot and Korn are nu metal, Unearth is metalcore, Protest the Hero is mathcore, Dream Theater is progressive metal, the Faceless are technical death metal, and so on. But genres are pointless in my mind.
