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.

- Do yourself a favor and check out Epica, Nightwish, Lacuna Coil, and Tristiana. These are progressive metal bands with female lead vocals and growly male vocals. Each of these bands have many songs that have a mix of both vocal styles. Hit Myspace or Facebook and check them out. Look up Epica's Living a Lie: The Embrace That Smothers off of their Divine Conspiracy album.

- Q: tell me some epic metal songs....
- Death Metal grew out of thrash metal in the late 80's except throw in some gritty lyrics of morbid obsession, death, pain, suffering, blah blah blah. Speed up the tempo sing with loud inaudible lyrics. Talk about raping dead babies, wear nothing but black and smell like $hit. Have album art of hell and death. Maybe throw in some stage antics with fake sacrifices and fake blood. Then boom you have a metal band, in other words an excuse of for not being able to actually play. It's a formula like anything else anymore.
- Q: I enjoy both, but i don't consider them Metal because if you mix lemonade and milk, it's no longer lemonade, because of the non-lemonade elements that were just added.I can't really think right now, i'm tired. Sorry.Discuss.

- Q: heavy metal songs
- sub genres help when I'm trying to describe a band, or when I'm looking for more of a particular sound, but it's a double edged sword because I think it limits people's imagination, everything has to fit perfectly in a category, but I find the best bands often do not fit perfectly in a category. some genres are superfluous duplicates of other genres, for example Folk metal is a real genre, as you can imagine it's tradition folk music + metal, but pirate metal is just folk metal + lyrics about pirates, that's not really a genre when you think about it, and neither is Viking metal.
- Q: any good metal,heavy metal,screamo bands you know
- Black metal is defined by it's rasped or screeched vocals, blast beat drumming and fast riffs. Not all of it is Satanic or Anti-Christian as some may believe. Topics are very broad from sci-fi to nature. Speed metal is much similar to thrash metal. Fast riffs, shouted vocals. Think of it as thrash metal's older brother. Death metal is most well defined by guttural vocals. The guitars can be anywhere from mid-paced to as fast a black metal. Although the more popular bands are known for their gorey themes, many do not conform to this set standard. Lyrics themes are very broad.
