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: I can't decide which is betterFavourite Black metal band - SatyriconFavourite Death metal band - Bloodbath
- No. I havent looked at the second link... but Ektomorph is Groove Metal. I have also seen them listed as Tribal Metal. I haven't heard a lot of their stuff... but I actually do like what I have heard, Thanks for reminding me of them... now that I actually have the internet.. I'll look up some more of their stuff. As for NuMetal..
- Q: last time I asked this question to a girl who come from U.S she said their music are death metal! but one of my frinds said that Slipknot has dj, so their metal is electronic metal!I wanna make sure it...Thank you to tell me it!
- Yes, to a point. Metal detectors send out a magnetic pulse, which induces a current in nearby metal and results in a magnetic pulse generated by the metal. How strong and how pure the return pulse is can tell the detector how much metal there is, as well as something about what it's made of. For instance, gold is a better conductor than aluminum, so it'll generate a stronger pulse for the same size object (other sensors can give some idea how big the thing is physically). Handheld units probably can't pick apart an object into types. If you had a copper/zinc modern penny, it would probably have that info programmed in and be able to tell you. But if there were a roll of pennies of different types all clumped together, wouldn't be able to tell you how many were pure copper and how many were zinc with copper coating. Note that coin-operated devices use a similar effect to tell if you've put a real coin or a slug into the machine. One of the challenges in designing the current dollar coin was that it had to have the same magnetic properties as the Susan B. Anthony dollars, since a lot of vending machines had been designed to take those.
- Q: Whats your favorite early 90's music genre Grunge or Heavy Metal.Whats your favorite band, of the two genres.
- The most expensive metal on the legal market is Californium, for sale at the Livermore Labs for $100 per microgram. This translates to $100,000,000,000.00 per kilogram. Even black market Plutonium is cheaper than this, or it was last time I bought any lol.

- In the Scientific Community, Hydrogen is accepted as a non-metal. One of the most common reason's for this is because Hydrogen is a gas (at room temperature). But u would probably say that mercury that is liquid(in room temperature) but also considered a metal. Experiments that justify Hydrogen's placement among st the Alkali Metals include very low temperatures and very high pressures, at which Hydrogen acts like a metal, being more electrically and thermally conductive than silver. But it is so far not judged as metalloid. But no can actually say that it is metal or non metal. Hope I can satisfy u with it. If further confusion feel free to ask.
- Q: I hate metal music! It's nothing but hating people and demons! It is soooo not cool!
- As long as you aren't a fatty, you should be ok. I walk on mine all the time, just make sure to walk on the frame trusses and not the open panels. Much safer.
- Q: is a battery a alkline earth metal?
- metal≠screamo Fine . . . listen to Agalloch,they are an amazing folk metal band . . . or if that's even a real thing, folk metal, but that's the best way to describe them, I guess.
- Q: Black Metal for me. The only death metal band I really enjoy (though TBH, I'm still exploring the genre) is Death. Black metal is more ambient and atmospheric, IMO.
- The term scrap metal encompasses both ferrous and non ferrous metals: ferrous - steel, iron, HMS and Non ferrrous - copper, aluminum, brass, bronze etc. Within each scrap metal category there are different grades, for example there is #1 HMS steel, #2 HMS steel, Bare brite Copper, etc.
