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: Espially considering that Metal evolves from Sabbath(Original Metal) - Metallica(Trash) - Antrax + Public Enemy(Trash + Rap)=(Nu-Metal )Korn,System of a Down,Linkin Park
- Metals are metallically bonded. this means there is a lattice of metal cations surrounded by delocalized electrons. This means that no electron is bonded to any specific ion in the metal lattice. (these ions are nuclei and inner shell electrons). this means that electrons are less tightly bound to the structure of the metal. this is why the photoelectric effect can occur (where light frees electrons from a metal surface completely).
- Q: k. I lovee metal i want to know the whooooole story... can anyone help?
- Order: *Full Metal Panic! *Full Metal Panic! Σ (Σ is the symbol for sigma not stigma.) *Full Metal Panic! Overload *Full Metal Panic! Surplus *Full Metal Panic! Comic Mission Σ is a sequel to the original Full Metal Panic!. Surplus is a sequel to Overload. Both Surplus and Overload are comedy/gag versions of the original Full Metal Panic! only. Comic Mission is just like Surplus and Overload in being a comedy/gag version of the original Full Metal Panic! but it also uses characters from Σ.
- Q: Why does people still refer slipknot as an Nu metal band?I hate it,it`s true that slipknot debut album is rapcore but now,their new album is heavier.What do you guys think???
- Metal, I like rock but a lot of it now just doesn't sound good anymore.
- Q: What kind of music do you like better between grunge or hair metal? For me it's the hair metal bands
- AMON AMARTH! They're like the kings of Viking metal
- Q: Hey all,Just got Metal Gear Solid The Lecagy Collection for PS3. Disc one has one game on it: MGS4. Disc 2 is supposed to have all the other MG games, including the original. When I start it up however, it only gives me the option of MGS2, 3, and Guns Of The Patriots. Any idea how to access the original Metal Gear game, plus the other titles listed on the back cover? Thanks!
- I personally think the whole 'Real metal' vs 'Fake metal' debate is kinda pathetic too. mostly because people just seem to put all the band that THEY like under the 'real' category and all the bands they don't like under the 'fake' category. I don't pay much attention to the whole thing personally. If I like a band I like them! I couldn't care less weather they're 'real' metal or not I just don't happen to be a huge fan of screemo and Metalcore but I have nothing against it
- Q: I'm looking for folk metal, power metal, and metalcore bands! thanks :)
- Group III to XI are all transition metal for me i would always look at the abbreviated electron configuration of the atom when you see D orbitals with electron then its a transition metal same goes for f orbitals the groups i mentioned are all transition metals hope this help
- Q: does anyone known any good metal instrumentals, open to metalcore, metal, hardcore, deathmetal anything heavy or some good metal bands that play instrumentals
- Well KP, I don't know {or care} what the 'experts' say, my personal opinion is that #2 is *not* Metal... It's a form of Rock {a sort of blend of goth and symphonic}, but not Metal. I'm not sure what my opinion of #1 is... Okay, basically, just because a group is female fronted doesn't mean they *aren't* Metal, but a lot of them just don't have that extra 'something' that lifts them into that genre. That's my tuppenceworth, but it's probably not even worth a ha'penny...
- Q: 92;m/ i love metal!!!!!!!!!
- Copper, Tin, Zinc, Magnesium, Nickle, Silver, Gold, Platinum
- Q: what is your opinion of this song.I like it alotYou should all know this song
- European, it traditionally always had a good number of bands and now, America has very little metal while the European metal scene, especially in the Eastern region, is still very fresh.
- Q: Metal started up really nicely in the 80's-EVERYONE was a metal-head!then in the 90's there were less metal heads, but still a steady flow of good, pure, heavy, wicked metal.now in the worst time in history-the 20th century, most ACTUAL metal bands are dead. there are few that spit out true metal, and the few that do are covered by bands claiming to be metal that are ultimately 'emo-screamo' which gives a bad name to metal itself. a true disgrace.so what EXACTLY happened to kill metal. when and where did this happen, why did this happen, how can we prevent it from happening again? it's like a pandemic.was it just rap music that killed metal, ore something more?
- They are nothing but d-block elements in periodic table
