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:Non metals?
Well only the older players use wooden hockey sticks, if they still prefer. They are actually made of graphite now. I don't think they were ever made out of metal, maybe because it was expensive, but I'm guessing it was because they didn't want to lug around a solid metal pole to play hockey with. HEAV-YYY!
Q:Question For Those Who Don't Like Metal...?
Metal Gear and Metal Gear 2: Solid Snake are located within the main menu of Metal Gear Solid 3: Snake Eater.
Q:Favorite Trash and norwegian metal bands?
Steel and Iron....jk lol Groove Metal, Alt-Metal, Melodic Death Metal, and Symphonic Metal
Q:Great Heavy Metal Bands??????????
Probably your harder new stuff would be New Metallica Korn Disturbed Element Eighty
Q:Reactivity of Metals?
since electrons in the sea of electrons are mobile, metals are able to conduct electricity when solid or molten .metallic bonding is the bonding of metals
Q:what is a metalloid/semi-metal?
Magnetism has to do with unpaired electrons. Electrons spin clockwise or counter clockwise. Generally they are paired. When they are not they create magnetism. Iron has 3 unpaired electrons and demostrates tahe greatest magnetism. cobalt and nickle also demonstrate some magnetism. Also, some of the rare earths and some alloys such as Alnico and steel. RECENTLY, several papers have been published on the use of polarized light for revealing the grain structure of metals and alloys. Hone and Pearson1 showed that by examining under polarized light a polished aluminium surface which had been anodized in a suitable electrolyte, the grain structure was revealed, differently oriented grains appearing with different brightnesses. Woodward2, by etching 'Monel' metal in a specific reagent, has found similar effects. Polished surfaces of aluminium and 'Monel' metal, being optically isotropic, do not react to polarized light as do the optically anisotropic surfaces of tin, zinc, cadmium, etc., and the above authors1,2 have attributed the optical anisotropy of the anodized aluminium and etched 'Monel' metal to the anisotropic properties of the surface film formed during anodizing or etching. Although this explanation may be correct, there is a possible alternative which involves the surface contour of the specimen, for it is well known that if pearlite is examined under polarized light no reaction occurs unless the specimen is etched. This has been shown convincingly by Baeyertz3 to be due to the presence of fine parallel grooves on the surface, formed by etching away the ferrite and leaving the cementite lamellæ in relief. Furthermore, Jones4 has shown that polarization effects can be produced by deeply etching a metal surface.
Q:What type of heavy metal are Cradle of Filth?
. . . . thrash came after Heavy Metal Its still around whats playing today is whats called Nu Metal, this is your Disturbed, Slipknot, ect, ect bands like Anthrax, Slayer, Metallica, ect ect are still playing and recording but they're reaching the end of their careers, no one can keep that going forever. So its not dying its just that all the big names are slowing down.
Q:What are three metals, three semi-metals and three non metals?
Heavy metal!
Q:Why are coins made of transition metals?
