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.


2,Main Features of the Ductile Iron Manhole Cover:

·High endurance

·High Strength

·Pressure Resistence



·Good visual effect

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:Can you use baby oil on metal?
Water, the conventional solvent, reacts very almost with any metallic. out of your checklist, the main resistant is Zinc (Zn). Water can oxidize metals with the O in H2O. As water's polarity makes it reactive with different polar components (people who can carry a value, and metals can carry a value, or beneficial valence). fee of reactions whether variety with each and each metallic.
Q:How to do these metal reactivity series questions?
* Metals are elements that have atoms arranged in rows. The electrons are easily released from metal atoms so that layers of metal atoms exist in a 'sea' of electrons. * Examples of Metals are gold, copper, lead, zinc, iron, magnesium, sodium, calcium and mercury. * Physical Properties of Metals include shiny lustre, greyish - silver colour, hardness, good heat and electricity conductivity, high melting and boiling points, malleability (can be hammered into a sheet) and ductility (can be pulled into a wire). Some exceptions to these are the metals - sodium and calcium (very soft), gold and copper (yellowish colour), and mercury (low melting and boiling points). * Chemical Properties of Metals Some metals are more reactive than others. This is because very reactive metals lose electrons easily. Metals such as sodium are very reactive and are explosive in air. Metals such as gold are very unreactive, and therefore do not corrode or tarnish in air.
Q:List your favorite (that means 1) metal bands of the following metal sub-genres...?
noble metals refer to elements having high resistant to chemical reaction or to corrosion.The term noble metals has its origins in ancient alchemy, the practice of attempting to transform base metals into gold. Noble metals is not synonymous with precious metals, (a term used to describe expensive metals used for making coins, jewelry, and ornaments) although gold, silver, and platinum are both noble and precious metalsosion meaning that they will not easily dissolve in solvents or in rust.,
Q:Could you please define the term metal for me?
let M be the metal ans as sulfide has an oxidation state of -2, then the metal sulfide would have a chemical formula of MS. The reaction is shown below. 2MS (s) + 3O2 ----------> 2MO + 2SO2 We know that 1 mole of metal sulphide will produce one mole of metal oxide. Let x be the molar mass of the metal we have that the molar mass of the metal sulfide is x + 32. The molar mass of the metal oxide is x +16. The number of moles of metal sulphide is 1.2/(x +32) The number of moles of metal oxide is 0.728/(x+16) As one mole of metal sulfide forms one mole of metal oxide, then 1.2/(x+32) = 0.728/(x+16) = 1.2 (x+ 16) = 0.728 (x+ 32) = 1.2x + 19.2 = 0.728x + 23.296 0.472x = 4.096 x= 4.096/0.472= 8.678g/mol.
Q:Would you consider Korn to be metal?
Because they are stupid and don't know what they are talking about. I've heard worse though, someone once told me Korn was Death Metal and Marilyn Manson was Black Metal.
Q:Is there such thing as "grunge metal"?
Alkali metals have one electron in the outer shell. Alkaline earth metals have two electrons in the outer shell. If the period number + the number of elctrons required for a full shell </=7 the element is a non-metal. Metals which are not alkali, alkaline earth or 'rare' earth (57-71 and 89-103) are transition metals.
