1,Cast Iron Manhole Cover Description :
A 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 is your favorite band of the following genres?Art RockSouthern RockPunk RockFolk RockPower Metal Symphony MetalMelodic Death MetalThrash Metal
- Hard rock usually still keeps some elements of the blues. Metal, for the most part, dispenses with the blues altogether. I <33 Chloe (: - Metal is screamo? F*ck you, ignorant douchebag. Don't answer if you don't know what the hell you're talking about.
- Q: Here is the question:Someone left two containers on the lab bench but there were no labels on the bottles with the names of the chemicals inside. If one bottle contains a metal and one bottle contains a non-metal, how could you tell which is which?
- The periodic table on the left separates the elements into three groups: the metals, nonmetals and metalloids. Most elements are metals. They are typically shiny, good conductors of heat and electricity, have a high density, and only melt at high temperatures. Metals are ductile and malleable, so their shape can be easily changed into thin wires or sheets. Metals will corrode, gradually wearing away like rusting iron. Nonmetals, on the right side of the periodic table, are very different from metals. Their surface is dull and they are poor conductor of heat and electricity. As compared to metals, they have low density and will melt at low temperatures. The shape of a nonmetal cannot be changed easily as they tend to be brittle and will break. Elements that have properties of both metals and nonmetals are called metalloids. They can be shiny or dull and their shape is easily changed. Metalloids typically conduct heat and electricity better than nonmetals but not as well as metals
- Q: I was listening to Metal on the radio one day, and I didn't recognize it and I liked it. Am I a metal musique fan?
- Germans have a long history of metal quality, I am afraid most modern metals may not be available in the market, as these are project specific, and very expensive too. Keep trying, may be you could get a piece for your treasure of metals.
- Q: whats ur fave hard rock band and metal band?
- i remember my teacher saying in class that copper is diffrent from most metals cuz it can be wanting to gain or lose electrons.... something cuz metal and metal is covalent bonding ...and metal nonmetal is ionic bonding.
- Q: Gunna try to write some songs. stuff that is genres like melodeth, satanic metal, and just regular ol metal. what would be a good heavy tuning for me?
- Agent Steel
- Q: music, rock, metal
- That okorder
- Q: I listen to all kinds of metal. Just shopping for suggestions on what CD to buy next.
- Thrash Metal - Reign in Blood - Slayer Power Metal - San Sebastian (Revisited) - Sonata Arctica Black Metal - Nattestid Ser Porten Vid I - Taake Death Metal - Von Unaussprechlichen Kulten - Nile Heavy Metal - I Speed At Night - Dio I know there are probably better songs and bands to put but thats what I came up with, my brain feels like jello right now......
- Q: since most salts contain a metal and a salt, how can one be sure that it is the metal atoms that emit photons when the salt is burnt (and analyzed under a spectroscope) and not the non-metals?
- I don't fully understand your question. Manufactured metals? or are you referring to ore minerals? If you are referring to manufactured metals, iron tends not to rust so much - not just because it seldom rains but because the humidity (water vapour present in the atmosphere) is so low. Cars left abandoned in the desert will remain in a useable condition years later. If you are referring to ore minerals, you find similar minerals in the desert to what you find in places with wetter climates. Evaporites, especially gypsum halite, are frequently found in a desert environment but these are not metals. Sulphide minerals of copper, lead and zinc would tend not to oxidise and hydrolyse so much but that said, I have personally seen oxidised copper minerals in the Atacama desert which is one of the driest places on Earth.
- Q: I want to add to my collection some good german metal, but something current, no scorpions or crud from the 80's, im talking current bands like, Rammstein, Megaherz, Eisbrecher . . stuff like that. I've only found 1 decent answer and it was Hanzel Und Gretyl, The rest were mroe along a trance industrial with Grendel, Reaper, odd stuff that doesn't even seem to relate to metal. Not sure if its just me, but it seems like Germany doesn't really have HEAVY METAL like US does, and canada, they got good stuff.I would like to be able to make out the words aswell, so no german deathmetal, power metal is ok, but lets try to keep it understandable.
- It is not possible for a metal to react with another metal. In chemistry, opposites attract and since both are positive ions, they cannot react with each other in a chemical reaction.
- Q: are cars really metal
- Dimmu Borgir, Symphony X
