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.

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:Rap or Metal?
Yes, Rust = oxidization, so the question should be what metals oxidize and that's most of them. But, to actually rust the metal has to contain iron, because iron oxidation is the process that creates rust and is unique to iron. That limits it to iron and its alloy (metal combined with other elements) steel. According to Wikipedia: Rust is a general term for a series of iron oxides, usually red oxides, formed by the reaction of iron and oxygen in the presence of water or air moisture. Several forms of rust are distinguishable visually and by spectroscopy, and form under different circumstances. Rust consists of hydrated iron(III) oxides Fe2O3·nH2O, iron(III) oxide-hydroxide (FeO(OH), Fe(OH)3. Rusting is the common term for corrosion of iron and its alloys, such as steel. Other metals undergo equivalent corrosion, but the resulting oxides are not commonly called rust. Given sufficient time, oxygen, and water, any iron mass eventually converts entirely to rust and disintegrates. The corrosion of aluminium is extremely slow because the resulting aluminium oxide forms a conformal coating, which protects the remaining aluminium. This process is known as passivation. Aluminum takes a long time to oxidize, copper takes on a green patina that stops it from further oxidization, other metals would eventually decay through oxidization, but only iron rusts. But even elements that we don't think of as metals oxidize like silicon.
Q:Metal bands??
Q:Your favorite Heavy Metal and Death Metal bands?
The d transitions metals are the ones in the middle of the periodic table between group 2 and 3...Ex:Cu ,Ni,Fe they have more than one oxidation state ...they form coloured compounds and solutions...they are used as catalysts Ex:Vanadium Oxide in contact process and Fe powder in Habour process...BTW they are called D-Transition metals bec their valence electrons are in the D Orbitals
Q:Progressive Metal bands?

Q:The Best Metal bands of this decade?
Hang on just a minute, [(Metal) + Oxygen have to react to get (Metal)-hydroxide and hydrogen]. Where does the hydrogen come from. Law of Conservation of Material or Mass - Atoms can be neither created nor destroyed. More correct would be (metal) + (Oxygen) react to give metal oxide. Now the metal oxide can react with water to give the metal hydroxide. 4Na + O2 --> 2 Na2O Na2O + H2O --> 2 NaOH
Q:Isn't metal just refined earth? ?
-q(metal)= c(calorimeter) x delta T -(2.44)(c metal)(72.5-100) = 1.23)(72.5-25.0) c(metal) = (1.23)(72.5-25.0) / -(2.44)(72.5-100) c(metal) =0.871 J/ g C
Q:why is guns n roses catigorized as hair metal there not hair metal ?
Dude you have to expand your thoughts if you think pointedly about anything art, life, and general other things you miss out on the greatest things. I love metal its my favorite style of music, but I'm willing to listen to anything.......exept christian music, country, and rap(rap does have a good beat sometimes though). Metal is a great way for me to get into any book I'm currently reading(that's hardcore) and go with the flow man.
Q:Metal lovers of R&P; a short survey?
yeah it is because of the review if u hav seen that then it says they will remove the left eye in the 4 part
Q:metal question???
Q:Engineering Catogeries for metals?
I've just now read zinc, lead, brass, and nickel are all toxic to parakeets. Rust is also toxic to them.........Stainless steel is safe. Steel is attracted to a magnet, so I would remove anything metal that isn't attracted to a magnet. ......It says plastic is safe, though I still wonder if there are different sorts of plastic. It does say PCV is safe.....I'm reading from a couple of different websites.
