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: And do metals, metalloids, and non-metals have something in common.
- Yes, all metals occur naturally in the earth and its materials. However, it is rare to find a metal just sitting there in its native (pure) form. Copper is about the only metal I have ever seen that exists in places as metallic copper in amounts that make it easy to just pick up and use. Gold is sometimes found as nuggets or in its pure state, but is very rare to find that way and usually requires a lot of work to collect.. Metals are more commonly found as oxides, sulfides, or carbonates that have to be mined, concentrated, and purified (smelted). Metals also exist as parts of many silicate minerals and as secondary elements in other non-metal bearing minerals. Recovering metals into their pure forms for use can be technologically complicated and sometimes expensive, even where the metal occurs in very rich deposits. Normal metal concentrations in earth materials are so low that it isn't worth the cost and effort to collect and purify. Although it would be possible to mine the soil of your back yard and smelt out some iron (for example), the amount you would collect would not be worth all the effort. You wouldn't get much and it would cost you a lot of money, a lot more money than the iron you got would be worth.
- Q: what will happpen if i heat it.. and can metal carbonates and metal hydroxides be mixed together ??
- I honestly listen to every style of metal. I mean, I definitely listen to some more than others but a few of my favorites are Deathcore, Folk Metal, Symphonic/Melodic Black Metal, and Doom Metal. Although I do pretty much listen to every genre on your list.
- Q: To all of the Metalheads out there, do you really HATE when people try to classify something as Metal when it most certainly is NOT Metal? You know what bands I'm talking about.-Everything with the word quot;corequot; in it.-ScreamoWhat do you call Metal?Whoever answers most closely to my opinion gets best answer.
- Personally, My fave is Bodies by Drowning Pool, there's also Slipknot, Serj Tankian, System of a Down, Linkin Park, Nine Inch Nails, and def some Metallica (mainly older stuff, but you might like the newer stuff too). Just find some older CDs at Co-op or some other store like that, where you can buy them used instead of spending too much green on something you don't like.
- Q: Why are locating agents used when working with different metals? It isn't because that they are colourless, but rather to distinguish between cos all the metals have similar colours right? thanks. :D
- I guess, those songs with guitar distortions are metal. :D
- Q: Nelson: Called hair metalMairlyn Manson: I have no idea what they are but its not metalLimp Bizkit: There lead singer used to be a rapper so they are not metal
- Dude! okorder
- Q: metal detectors these days can detect metals with out iron in them.....so magnetism seems impossible...
- Maybe okorder
- Q: anyone know some good heavy metal bands?lyk they're really loud!! lolz ^^, tnx in advance!!
- Doom okorder
- Q: Hey i would like some help becuase I just really got into metal 1 year ago and I would like some help.I don't want to find some metal heads and act retarded in front of them or act like a poserAnd what to watch out for thx (:
- What is the formula of the metal oxide. MO? M2O? MO2? You need to know in order to solve the problem. I will show you how to solve it, assuming it is MO (if it is not, you will need to account for that). If we pick an arbitrary number, like 100g, 67.2 g is metal and 32.8 g is oxygen. Since the atomic weight of oxygen is 16.0 g, 32.8 g O / 16.0 g/mol = 2.05 moles of oxygen. This is the part where the stoichiometry is important. Depending on the formula, this would determine the number of moles of metal. MO gives you 2.05 moles M (1:1 M:O), M2O gives you 4.10 (2:1 M:O), MO2 gives you 1.025 (1:2 M:O), etc. 67.2 g M / # moles M = MW of M Then use the atomic mass values on the periodic table to figure out what metal it is. Good luck.
- Q: For those of you who know what you're talking about (No Slipknot and BVB here), would it be agreeable that Alternative Metal is not in any way related to Nu Metal? I'm not as familiar with the genre as I should be to make this evaluation, but is alternative metal a gunge-metal fusion? It seems to be, because Alice in Chains, Tool, Helmet, RATM and other bands that fit into this category seem to be just that. I feel like I could be totally incorrect here, but is this an agreeable statement?
- Yeah, Metal Gear Solid 3 is the first game in the series chronology. Here's the chronology: Metal Gear Solid 3: Snake Eater Metal Gear Solid: Portable Ops Metal Gear Solid: Peace Walker Metal Gear Metal Gear 2: Solid Snake Metal Gear Solid Metal Gear Solid 2: Sons of Liberty Metal Gear Solid 4: Guns of the Patriots Metal Gear Rising: Revengeance The gameboy color game Metal Gear Solid: Ghost Babel is not set in the same continuity as the original Metal Gear Solid, but instead serves as an alternate sequel to the events of the original Metal Gear, set seven years after Solid Snake's mission in Outer Heaven.
- Q: ive never played any metal gear games, and i heard the metal gear series is amazing, should i get it? if yes which one in the series?
- Get the new twisted metal thats coming out for the ps3. I heard it was gonna be sick awesome.
