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 dose metal fight against the most? Main stream pop? Indy? county? stuff like Enya?Pick something and explain why, and which style of metal you most prefer. Or if your not a metal fan but but another musics explain how you see metal opposing what music you like and how.Examples are welcome in your explanation.
- challenging aspect. lookup using a search engine. it can assist!
- Q: Okay, I got into this discussion with my roommate debating which of these genres is better. He says he thinks bands like Slipknot and Korn are better because they have a more aggressive stage presence and deep meaningful lyrics. I'm not saying they suck, I'm just saying that I believe that old metal bands are far better than new metal.I will agree with him that there are some pretty good guitarists in those kinds of bands, but with lyrics like I will eat your heart then wear it as a hat I have a hard time comprehending with that. I told him that it was because of bands like Led Zeppelin, ACDC, Aerosmith, and Van Halen that these new metal bands exist. Bands like Slipknot may be good in the musical talent sense, but they'll never be as big or as iconic as Led Zeppelin. Plus, I know for a fact that these guys wouldn't come as close as good as Jimi Hendrix, Eric Clapton, or Eddie Van Halen. So what do you guys think? Winner Gets 10 points!!!!!

- Q: thnx !
- Black Metal is, but Folk Metal too. I find both to be very appealing to me. I haven't heard anything that can make me feel the way I do when I listen to some epic Black or Folk Metal bands.
- Q: I go for metal music.
- isn't it corpse paint and rawness some do it nicely some sound so undesirable that the 1st actual recording ever sounds greater advantageous its so wasteful. CC (new cd as reliable as ever), Morbid Angel (new album is arrive sometime quickly great!), and Carcass (who is conscious a pair of recent album yet they been traveling) they are death metallic. no longer many reliable Blackmetal out anymore like Darkthrone that's a could desire to as they been around continuously additionally the hurricane challenge Mutiilation is sorta nicely known yet constrained then I kinda pay attention to 3 new stuff like Kult Ov Azazel. i do no longer in elementary terms pay attention to easily metallic.
- Q: By metal i mean Death metal, industial, melodic metal,that kinda stuff. Also who listens to these bands:-Devil Driver-Behemoth-White Chapel-In Flames-Cannible Corpse-Lamb of God
- The active ingredient in bleach is the hypochlorite ion ClO- (Na+ salt) which is a strong oxidizing agent: ClO- + H2O + 2e- -> Cl- + 2OH- E = 0.89V [1] I have +0.81 V from another source. From this reduction potential bleach should from a thermodynamic stand point oxidize just about every common metal with the exception of gold (Au) and possibly silver (Ag) as they are have higher reduaction potentials [1]. Let's take Ni as an example: Ni2+(aq) + 2e- -> Ni(s) E = -0.25 V turning the last equation around, changing the sign and combining it with the first equation we have Ni(s) + ClO- + H2O -> Ni2+(aq) + Cl- + 2OH- E = +1.14 V the +ve potential makes it highly allowed. But thermodynamics does not tell about the rate. What probably happens is that Ni(OH)2 precipitates and protects the surface from further attack Ksp for Ni(OH)2 is 5.48×10-16 [2]. Metals that are amphoteric (react with acid and base) such as Al and Zn will probably dissolve in bleach soln. But again the surface of Al is Al2O3 that may protect the Al from attack at RT. Things to think about.
- Q: it's juz that i read somewhere that it's the seed 2 black metal, n that death metal = black metal. n that black metal could bend ur faith or something like that. really, anyone offended by this q, i'm so sorry, but i juz need an answer that could, well.. satisfy my curiosity.after all, u ppl have better judgement on this than i am.
- Deathcore (early Job for a Cowboy, the Acacia Strain, Emmure, more recent Cryptopsy, Suicide Silence, Whitechapel, etc.) is number one, without question. There was a time when I would have said Nu-metal, but it's largely dissipated as a major force. A close second is (mainstream) Metalcore (Killswitch Engage, Trivium, Atreyu, Bullet for my Valentine, As I Lay Dying, etc.). I qualify with mainstream because some acts, most of them verging on Mathcore, such as Converge (who have admittedly achieved a decent amount of mainstream success) and Botch are quite good. Nu-metal will show with a near tie. Honorable mention goes to Post-metal. I have nothing against bands labelled as Post-metal (Pelican, Isis, Neurosis, Russian Circles, etc.), and, in fact, many of them are good. My problem is that it should not, by any reasonable argument, exist as a classification. Not only do the bands grouped under it have barely enough in common to group them together, they all fit neatly enough under another, already existing, genre.
- Q: why can metals conduct? and what is metallic bonding?
- Metals do become brittle - depending on their thermal history. Generally speaking, the harder a metal is, the more brittle it is. Some examples of brittle metals: Iridium, Bismuth, and man made Plutonium (Pu). Similar to most substances, metals solidify as many separate crystals. The line where two or more crystals touch is called the grain boundary. If the grain boundary is weaker than the crystals themselves, then a crack can easily propagate through this boundary and fractures occur. If the metal is treated in such a way so that many multiple crystals form simultaneously (as when the metal is heated to an extremely high temperature and then cooled rapidly), then multiple, interconnected grain boundaries form and an impact with a high enough force can cause these boundaries to break apart making the metal appear to have shattered.
- Q: There is so many names and different subgenres. Thrash, groove, metalcore, deathcore, death metal, doom metal, black metal, gothic metal, speed metal, power metal. I mean, it kinda makes it seem like black sabbath and judas priest are the only heavy metal bands, ya know what i mean? So what is considered heavy metal?
- Shinedown okorder
- Q: Just listen to 4 words and scream aim fire theres no way those 2 arent metal and they also have made rash metal riffs and matt screams quite a bit like Chester in Linkin Park or Corey in Slipknot/Stone Sour
- Random, eh? Obituary (Death Metal) Persuader (Speed/Power Metal) Enslavement of Beauty (Gothic/Melodic Black Metal) Cynic (Jazz Fusion/Death Metal) Hyades (Thrash Metal) Dark Empire (Progressive Power/Thrash Metal) Freedom Call (Power Metal) Theatres des Vampires (Gothic Metal) The Chasm (NWOBHM-influenced Death Metal) Mob Rules (Power Metal) Lake of Tears (Symphonic Gothic Metal) Communic (Progressive Metal) Witchery (Speed/Thrash Metal) Angra (Progressive Power Metal) Waylander (Folk/Black Metal) Dark Suns (Dark Progressive Metal) Blaze (Heavy Metal) Time Requiem (Neo-Classical Metal) Kreator (Thrash Metal) Should be enough.
- Q: NOT what does acid do to metal! I already know that it weathers it!!!What does metal(iron,magnesium,copper..) do to acids?Weaker or stronger?pH level changes??Please help! I need this 4 my project!Thanx!
- I'm assuming that you are asking about acids and bases in water in my answer. Metals should not be considered as bases in a direct sense, because their reaction with water, if any, must first involve oxidation - in which the metal donates electrons to water and the water reacts to form hydrogen gas, plus hydroxide (so, yes, after reaction the solution is basic). Some metals (so called active metals) do this reaction - these include all the group 1 and group 2 metals (Li, Na, K, Rb, Ba, Ca, Sr, and Ba - with Mg the reaction is slow and it is very slow for Be). Other metals will not react with water at all (like silver or gold), other only react with acidic aqueous solutions. In all cases where reaction occurs, there is oxidation of metal AND formation of hydroxide (or reaction of the hydroxide formed with H+). Metal oxides of electropositive metals often react to form hydroxides, which can then dissolve as bases. The metal hydroxides are bases (or yield the base hydroxide when they dissolve). Added note: Electropositive metals are those from which taking an electron is relatively easy - the most electropositive metals are those on the left hand side of the periodic table (like those I listed.)
