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.

- Yes okorder
- Q:i dont want screemo i like the older stuff but all i love modern metal to
- there are many. here is a quick list that i have on the ipod. a good variety of heavy metal and a bunch of progressive rock too. angra (progressive) armored saint (heavy metal) black sabbath (classic rock) children of bodom (black metal) dragonforce (progressive) dream theater (progressive) dream evil (progressive) edguy (progressive) evergrey (progressive) fates warning (progressive) gamma ray (progressive) queensryche (heavy metal/progressive) iced earth (heavy metal/progressive) in flames (heavy/black metal) luna mortis (female vocals)(heavy metal) stratovarius (progressive) helloween (progressive) machine head (heavy metal) megadeth (heavy metal) nevermore (heavy metal) nightwish (female vocals)(progressive) onward (progressive) ozzy (classic metal) pantera (heavy metal) sentenced (heavy metal/progressive) slayer (heavy metal) sonata arctica (progressive) stratovarius (progressive) symphony x (progressive) trans siberian orchestra (progressive/symphonic) although many bands claim the mighty met and maiden as influences. here is a bit of clarification. we all know heavy metal. black metal is a more extreme version of heavy metal. usually coarser sounding vocals. progressive metal is a different animal. the songs are usually longer. sometimes based around a concept. even whole albums based off one idea(i.e dream theater's metropolis pt. 2 or iced earth's the glorious burden) usually extremely proficient musicians. tenor vocalists are the norm. many times they have a lot of orchestration on keyboards. it is not for the faint of heart or mind. you should have a liking of classical music since there is a lot of references to it in there. but if you give some other stuff a chance you will see it is so much better than the crap that most american music is. most of the good metal is coming from europe.
- Q:Does anyone know of ANY metal songs that have Dubstep drops?
- Metals cannot react with each other individually. Theymay only displace each other from their metal salts depending on their lace on the reactivity series. E.g AgCl + Na ---> NaCl (table salt) + Ag(silver metal) This is known as a displacement reaction. When we hear the name stainless steal or brass and itis a combination of metals, they aren't actually reacted but combined like a mixture.You can say it is like makinga cake e.g stainless steal is a combination of iron, nickel and chromium.
- Q:ive never played any metal gear games, and i heard the metal gear series is amazing, should i get it? if yes which one in the series?
- 3 and 4 were both pretty meh. Black took the game back to its roots (and its orignal developer), and was basically like the first two games. Not quite as fun, but much less frustrating controls.
- Q:What metal genre is the heaviest.
- I like a lot of different hard rock and metal bands. In my opinion, here are some of my favorites in no particular order: Led Zeppelin, Megadeth, Tesla, Dokken, Queensryche, ZZ Top, Alice in Chains, Heart, Ratt, Iron Maiden, AC-DC, Rush, Steel Panther, Motorhead, Foo Fighters, Motley Crue, Dio, The Cult, Crazy Lixx, Rose Tattoo, Airbourne, Big Cock. There are many others....
- Q:Name your favorite sub-genres of metal and name a few bands from each sub-genre you mention as well. My favorites are thrash metal, metalcore, death metal, deathcore, technical death metal, melodic thrash metal, and melodic metalcore. I don't mind symphonic black metal either, although I have only heard one band (Abigail Williams) that I like so far.
- Metal is my one outlet of aggression in an otherwise placid demeanor. metal=good
- Q:What is a definition of a metal?Why is mercury considered a metal when it is so quot;fluidquot;?
- Progressive Rock Post-Rock Alternative/Indie Electro-Indie Progressive Metal Doom Metal Black Metal

- hard problem. query in yahoo or google. just that can help!
- Q:What are two synthetic metals (not naturally ocurring) on the periodic table??
- It depends on their stability with other elements. The charges determine how many electrons it is giving up to a non-metal.
