Product Description:

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.

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:What are your favorite sub-genres of metal?
NO! If anything, metal back then is better than metal now. People love stereotyping metal, saying oh its just satanic screaming and stuff and stupid accusations like that. Most people who hate metal, hear it everyday and just don't know it. Old school metal, especially, is what made rock and metal today, and even spawned off and inspired alot of other artists. Now then *waits for loads of agreements, or loads of pop and rap kids to start stating retarded crap, followed by some poseurs bringing up metalcore and nu-metal
Q:metal bands with in between vocals?
Different metals have different properties which make them useful to humans, for doing a wide range of things. Shininess: metals such as bronze have been used as mirrors for thousands of years. Also, shiny things are attractive, so metals have been used for decoration and jewellry. High melting and boiling point: Some metals such as tungsten, have very high melting and boiling points. These are useful in places where you need metals which can stand a lot of heat, such as in smelters and boiler and such. Malleable: some metals such as copper and gold are very malleable: this means they bend and flatten easily when hammered or otherwise compressed. Very useful for coating things (a small amount of gold can be used to coat a large area: very useful for decorating buildings and statues and such!!), and anywhere you need a flexible metal. Also, malleable metals can be formed easily into all kinds of useful tools just by using a hammer and an anvil - blacksmiths use this property of metals to great advantage, to fashion useful tools and implements. Ductile: Ductibility is the ability of a material to be stretched into wires: copper, gold, aluminium, steel, etc. Wire is essential for electronics, which our civilization depends upon heavily. Ductibility can also be used to make things like nails: just stretch a piece of metal into a long, thick wire and cut it at reagular intervals and flatten one end: viola, nails!! Sonorous metals: for music, especially bells and brass instruments!!
Q:What are some good pirate/viking metal bands?
Death metal. Its AWESOME!
Q:Is the band Arkhon Infaustus considered blackened death metal?
A semi conductor and a conductor differ mostly in the number of free electrons in the element. I'm not clear on what you mean by generate electricity as they do not normally generate electricity but are used to make various electronic components (transistors and such ) silicon,germanium are two examples.
Q:Metal Category.?
1984-1990 Pretty much all of the best thrash metal releases were released between these years, in addition in the late 80's you started to get the sub-genre split up, so there'd be speed metal just about to edge into power metal, death/thrash popping up more often (a godly combo), Exhorder starting the in your face rude boy groove sound with the immense album Slaughter in the Vatican, great for more technical thrash metal fans too, the amount of awesome releases in 1989 alone is staggering. A lot happened in those 6 years, and most of it was goooood. The 90's is underrated though if we're talking about true metal, the major rise of Black, Death, especially Power and even folk metal as we know it happened during the 90's, so just 'cause a load of kids thought slipknot and linkin park were metal doesn't make the 90's bad for actual metal.
Q:Metal fans?
America is home of some of the best metal bands out there- Slayer, Metallica, Megadeth, Exodus, Testament, Pantera, Cannibal Corpse... But Europe has some really good and some of the best- Kreator, Behemoth, Iron Maiden... Plus most of the black metal bands So maybe Europe by a hair.
Q:What is the order of reactivity of hydrogen, metal X and metal Y?
volume of unknown metal = volume of water and metal - volume of water =23.4mL-15mL=8.4mL=8.4cm^3 Density of unknown metal =mass of the unknown metal/volume of the unknown metal=8.27g/8.4cm^3=0.985g/cm^3
Q:Do you like my page of metal?
Metal isn't really disrespected, metal fans just have a persecution complex.
Q:What is the heaviest metal genre?
I would call them Alternative Metal. There are a lot of Alternative Metal bands that get compared with Nu Metal bands even though I don't believe that they sound similiar to Nu Metal at all.
Q:pro wrestling most metal wrestlers?
Here are the main ones Classic - Iron Maiden Thrash - Anthrax Avant garde -Celtic Frost Power - Lost Horizon Stoner - Corrosion of Conformity Progressive - Dream Theater Death - Carcass Black - Dissection Doom - Candlemass Grindcore - Napalm Death Gothic - Flowing Tears Folk - Falconer Viking - Bathory Symphonic - Therion Note - Metalcore IS NOT a subgenre of metal. It is a subgenre of hardcore which is a subgenre of Punk. I can not stress this enough.
