1,Cast Iron Manhole Cover Description :
A 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.

5,FAQ:
We have organized several common questions for our clients,may 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 3 properties of metals and define each.
- I never really got why people hate different genres of metal and then take it personally when someone doesn't like what they like. It's all childish. It's as if they don't want a variety of music. Can you imagine if all the greatest rock n roll musicians listened to what others said when they were starting bands? There wouldn't be rock or metal. Music would be so bland.
- Q:For me, It's currently Industrial Metal.
- My fav metal band is Judas Priest. They're a British classic metal band. Check out Nighcrawler, Hell Patrol, and Living After Midnight (more of a rock song, but still great). There's also their song Metal Meltdown... That's a good one. Also, I love Iron Maiden... Another classic metal band!!! I'm sure you know who they are ;D A modern metal band... There's System of a Down, which is my fav. They're metal, so don't listen to somebody if they say they aren't... Just listen to their Toxicity CD. They're a progressive-rock/metal/doom-metal(psyche... genre. They rock pretty hard dude. Another modern one is Children of Bodem, which is more death metal than anything...
- 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:whats the story order of the metal gear solid series is it like 3 then 1 then 2 and finally 4
- Godspeed You! Black Emperor they are minimalism and rock (post-rock)
- Q:tell me some epic metal songs....
- It's a sub-genre of heavy metal. Death metal may include violent or dark lyrics which focus on death as a nihilistic metaphor(Although, many do not) chromatic chord progressions and a varied song structure without a standard verse-chorus arrangement.
- Q:I think that metal bats go further. My friend thinks wood bats go further
- Y'know, okorder
- Q:what are teh metals used for communications and their cost., efficiency resistance?
- Metal + Acid = Metal salt + Hydrogen for example: Sodium + Hydrochloric Acid -----> Sodium Chloride + Hydrogen. 2Na(s) + 2HCl(aq) 2NaCl(aq) + H2(g) boring much? :) hope this helps
- Q:And, what are three ways other than welding to fasten metal?
- Metal Man. Your name doesnt do you justice. Being Metal Man you should know that there are still tons of real metal bands out there besides just the emo metalcore emocore asking alexandria type stuff. There is a thrash revival and and a traditional metal revival happening with tons of amazing new bands coming from places like Sweden, Finland and Germany etc. Stop complaing about the mainstream metal scene in the US and start living up to your name.
- Q:I prefer Black Metal
- some metal sucks, some rap sucks.. but they both have great traits and talents and tunes. I'm more of a metal person. but I'm open to anything. I hate bad metal/new metal/fake metal like friggen... system of a down and slipknot and sh it. that stuff is lame. its not even METAL. so what the hell.
- Q:im lookng for some good grindcore death and brutal death metal bands i know dying fetus, six feet under, disavowed, napalm death, cannibal corpse and nasum.please no melodic death/black, black, ghotic, doom metal
- Folk and power metal. I mean I'm a dork, but I'm not that big of a dork. Putting on a kilt and playing a hurdy-gurdy while someone chugs away at a recycled Gothenburg riff and sings about mead and slaying the Midgard Serpent over an oom-pah rhythm doesn't make your band innovative. Or cool. BQ: Does The View count? If not, take your pick out of Six Feet Under's Graveyard Classics collection or anything under the ignominious banner of pirate metal.
