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

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:Different Metals?
please get this out of chemistry section.
Q:This type of music! Metal/classic/ Symphonic metal?Best Answer!?
Rock Roll. i've got in no way been into the great hip hop/rap element, u . s . a . is horrific, heavy metallic is only too screamy, jazz and classical (sorry if this offends actual each physique accessible) is extra for old human beings. If I had to place them so as, it would be Rock, Hip Hop, Heavy metallic, Jazz, u . s . a ., then Classical.
Q:Whats next for metal?
Metals like iron, potassium, zinc, and magnesium are found in the human bloodstream and are needed or else we'd all be dead.
Q:Metal Gear for Wii?
if the metals cannot be obtained by displacement reactions then u have to do it by electrolysis. this ensures that the metal is a lot purer than extracting it by heating its ore. it has to be pure in order to be used for a specific thing. the pure metal piece is made the cathode(negative electrode that attracts the positive cations) n the impure metal piece is made the anode(positive electrode that attracts the negative anions). metal ions leave the anode n go to the cathode. the anode in this way loses weight n in the end all the pure metal will be plated on the cathode. this means that the pure metal cathode has gained weight and its still pure. now what happens to the impurities? they fall to the bottom under the anode as sludge
Q:Nu-metal vs regular metal?
there are quite a few synthetic metals on the periodic table.
Q:why people think the Metal Gear Series is called Metal Gear Solid Series?
Q:Is it true in hockey the sticks are made out of wood beacuse metal would be more exspenive?
No, they aren't. Some metals are more reactive than some non-metals and some are less reactive. You can't say all the metals are more or less reactive than all the non-metals. The most reactive metal is Fr (francium) and the most reactive non-metal is F (fluorine). Elements become more reactive at the extremes of the periodic table. The elements in the lower-left corner are the most reactive metals and the elements in the upper-right corner (beside noble gases, they generally don't react at all) are the most reactive non-metals. There is a Pauling scale which measures the electronegativity of elements. In this scale, fluorine has a number of 4.0, oxygen 3.5 and francium -1.0. Hope that helps! Louise
Q:Help with semi-cunducting metals and just cundicting metals?
Carbides and Ceramic-metals are hardest ..
Q:Good metal bands please?
Black metal and Death metal originated from thrash metal thrash metal has a less heavy sound then black and death metal and black metal has a more high pitch hasty eviler sound than death metal examples of thrash metal:Metallica,Slayer,Nuclear Assualt,Kreator examples of death metal:Cannibal corpse,Dying Fetus,death examples of black metal:Mayham,Dimmu borgir,gorogoth
Q:Who killed the metal?????
Metal Gear Solid HD will keep you entertained for months, being that each game is pretty long. However, if you're an online player, go for Twisted Metal, as the online on it is pretty fun (or so I heard).
