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: Black metal is never normally really associated with technical skill although there are definitely bands that are more than proficient. Some however seem to stand out abit more, and one of those bands imo is Abgott.
- Modern technical death metal is pretty god awful. As well as modern brutal death metal. Luckily the rise of new-old school death metal bands is overtaking the influence of those terrible, terrible bands. And Its not as bad as Nintendocore..., HEY, there's only one nintendocore band and that's HORSE the Band, and HORSE the Band rules. HtB only made up the term nintendocore as a joke, then other douchebags thought it'd be funny to try and make it a real thing. NO. But if you would consider crunkcore in the metal spectrum (which I probably wouldn't), then it is far and away the worst. But apart from that, probably nu-metal. I still love System of a Down and Deftones and I still respect Slipknot for getting me into extreme metal (I know they're not extreme metal themselves, but they got me into it), but just about every nu-metal band otherwise sounds absolutely boring as hell to me.
- Q: Best Metal song of all time?
- 1. Lustre = Metal 2. Tightly held in Valence electrons = Non-Metal 3. At the right side of the periodic table = Non-Metals 4. Semiconductors = Metalloids 5. Good conductors of electricity = Metals 6. Usually quite brittle = Metalloids 7. Properties intermediate between metals and non metals = Metalloids 8. A variety of colors = Metals 9. Three to eight valence electrons = I don't get it. 10. Poor conductors of heat = Non - Metals
- Q: What are some good heavy metal bands of the 2000's and present. Please give me a list.
- Yes!! Finally someone who agrees with me! Ah, those were some fun times! I went through a can of Aqua Net every three days! LOL
- Q: I'm Crazy about Metal music....so i wanted to know about the differnce between death n Black metal musi?...
- all labels are absolute crap now there's no way you can look at them bands label themselves on how they want to be seen when most of the times now they aren't actual that type of music I prefer black metal extreme metal is a waste of music that some band just came up with to make themselves sound cooler hardcore metal is probably the same thing, but there's black metal out there that is harder and faster then hardcore really, just listen to bands you like, who the hell cares about labels
- Q: Anyone know of any good metal bands that play with orchestras?
- Thrash Metal
