1,Cast Iron Manhole Cover Description :

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.

 5FAQ:

We have organized several common questions for our clientsmay 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: Metal!!

Q: Everyone keeps telling me they are not real metal.
People consider As I Lay Dying and Bullet For My Valentine and all those other horrible nu metal,and emo bands that claim to be so called metal because they believe everything they see on MTV, and think their definition of metal lyrically is oh my girlfriend dumped me or whining and slitting my wrists. I'm sick of it as well as these poser metal bands like.. 1)Slipknot 2)As I Lay Dying 3)All That Remains 4)Hawthorne Heights (yes people have told me these are death metal but aren't) 5)My Chemical Romance (not metal but their myspace claims it to be metal some mainstream metal websites do to) *Basically anything that claims to be metal and is mainstream isn't true metal These guys are really twisting the truth of the metal message and even death metal its not supposed to be talking about like I said my girlfriend dumped me personally I take the message as genocide of the human race and kill and destroy everyone either that or I'm just a misanthropist. Real underground unheard of metal > all mainstream wanna be poser, controlled by the music corporation,emo so called wussified version of metal *true metal and death metal to is not whining about teen angst which these poser mainstream so called metal bands to. All those bands are a joke, and are the far from metal. Whats even worse these posers think they are the top s*it just for listening to so called Death metal bands like... Slipknot and think Marilyn Madson is black metal (which both aren't) its just a joke.... *Look at a band called Otep and their song Blood Pigs on youtube they are a horrible example of Death Metal that most people believe they are but they are just poser nu metal and their lyrics are just about whining about why their gf or bf dumping them
Q: I will give someone as many points as possible if you give me a scale (lightest to heaviest) of types of metal music like heavy, black, thrash, etc.
you skipped glam lol, glam's like WWII for Germany but it did happen. you went over the history of metal and glam's in it
Q: I have some thin sheet 'tin' metal I believe I bought from home depot. I'm trying to make some sheet metal panels with a patina on it. Does anyone know what the sheet metal at HD is made out of and can you oxidize or put a patina on it? If not, is there a certain type of sheet metal I can buy that would work for a decorative patina?
Ah yes, but Nu-Metal has so many other influences an open-mind is mandatory to listen to it, Electronica, Grunge, Metal, Rock, Hip-hop besides every black metal fan I know hated Ulver while he was black metal so...
Q: When it comes to........Death Metal?....Black Metal?....Melodic Death Metal?....Heavy Metal?....other Metal?
Aluminium metal combines with the oxygen from the air on heating to form aluminium oxide. The reaction can be represented using a balanced equation as 4 Al (s) + 3O2(g) => 2Al2O3(s)
Q: It is a fusion of hardcore and METAL. So why isnt it metal? I agree that some metalcore bands are in it for the money, but all bandsgt;
This is the correct order to play the games in: Metal Gear Solid 3: Snake Eater [PS2] Metal Gear Solid: Portable Ops. [PSP] Metal Gear [NES] Metal Gear 2 Solid Snake [SNES] Metal Gear Solid [Playstation] Metal Gear Solid VR Missions [Playstation] Metal Gear Solid 2 [PS2] Metal Gear Acid [PSP] Metal Gear Acid 2 [PSP] Metal Gear Solid 4 [PS3] Metal Gear 1 and 2 are on MGS3: Subsistance, as extra's. If you wanted to play the games in the correct timeline, this is the order you should play them. Naked Snake [Big Boss] was the star of MGS3 and Portable Ops. You play as Solid Snake in every other Metal Gear game. Metal Gear Solid 3 and MGS Portable Ops took place before any other Metal Gear games, in the 1960's. Every other game takes place in modern times, 1990's up til now. I hope this helps!!
Q: I thought it was rap mixed with metal, but I constantly am being told that certian bands I thought were something else, like Slipknot for example, are actually Nu Metal. So, what exactly IS Nu Metal?
Primal Fear Angra Gamma Ray
