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.
2,Main Features of the Ductile Iron Manhole Cover:
·High endurance
·High Strength
·Pressure Resistence
·Anti-corrosion
·Anti-theft
·Good visual effect

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: Death metal would be nice, but I'd prefer black metal.If you are, will u b mein?
- Metal factors (i'm assuming we're talking about factors) are just right conductors of warmth and electricity, are usually malleable (will also be flattened into skinny sheets) and ductile (can also be rolled into wires), and type cations when forming ionic bonds with non-metals. Now not all metals are robust, although many are, and most have a high boiling factor, although mercury (a steel) is a liquid at room temperature. Non-metallic elements are the reverse. Poor conductors, on the whole no longer malleable or ductile, and form anions when in ionic bonds. Though most stable non-metals are brittle, some are very tough. Boiling elements vary wildly, though most covalently bonded compounds (two or more non-metals in a bond) are typically gases, some base factors, like carbon, have boiling features above 4000K.
- Q: music, rock, metal
- never let metal jewelry touch water. any kind of liquid. so take off metal jewelry off when you know its gonna be hot. - the sweat - i think metal jewelry not only smells like metal, but i think it rusts and turns brown.. so be careful! oh and the smell, put your jewelry in a tiny box of perfume samples, or a box that smells like perfume for about a day or two. (not only will it not smell like metal, it smells like your favorite perfume!, if your using your fav. one) if you wash it the smell will still be there, so don't waste your time washing it.
- Q: Why are metals and their atoms insoluble in water? Thank you.
- 1) by adding a less noble metal (for example Zn or aluminum to steel), which will corrode faster, meaning will oxidize faster). It's the same principle as in a battery - a more active metal will dissolve faster 2)by galvanization - physical protection by coating a corrosion-prone metal with a protective agent like zinc. Also a layer of paint, enamel, or plastic can be applied.
- Q: I need info about ferrous metals.
- metal will catch on fire in the microwave yes your microwave is probably ruined you should never put any form of metal in the microwave un less the metal comes with the microwave already
- Q: black metal, death metal, doesn't matter
- Metals are usually found in various ore. They look like rocks. Ore is usually metal elements mixed in with other unwanted elements. but when refined and the metal element is extracted the ore becomes metal. The ores is found all over the earth and inside of the earth. You can find Pictures of Metal ore on google images.
- 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.
- My least favorite Metal sub genres are Death Metal, Screamo, Glam Metal, and Today's Metal like A7X and Bullet for my Valentine I hate those bands I hate any Metal that has screaming. I like my Metal Old School like Black Sabbath, Judas Priest, Metallica, Megadeth, Anthrax, Dio, and Iron Maiden thats the only Metal I like and Grunge Metal like Alice in Chains and Soundgarden some of their music is heavy.
- Q: I need more bands to listen to, my top ten would probably be something like this:1. Immortal2. Ensiferum3. Stratovarius4. Amon Amarth5. Blind Guardian6. Be'lakor7. Powerwolf8. Behemoth9. Manowar10. VenomOther bands I like are: Heathen, Megadeth, Death, Exodus, Death Angel, Cathedral, Candlemass, Gamma Ray, Rhapsody (of Fire), Nile, Bathory, Mayhem, Carpathian Forest, Iced Earth, Gates of Slumber, big fan of the drummer Frost, 1349, Keep of Kalessin, Demons and Wizards, Korpiklaani, Entombed, Pathfinder, Wolves in The Throne Room, Cannibal Corpse, Pagan's Mind, Exodus, Black Sabbath, Dio, Omnium Gatherum, Emperor, Overkill, Demonaz, Accept, Belphegor, Mercyful Fate, FleshGod Apocalypse,Dissection, Taake, Aura Noir, Wintersun, Morbid Angel, limbonic art, Cloudscape, I know alot more, but I'm going to stop there. If I had to narrow it down I would say my favorite genres are all types of black metal (excluding raw) , finnish folk metal, and European power metal.
- Most commonly recycled metals include iron (and steel), aluminum, copper, lead, silver, gold, zinc, nickel, manganese, titanium, and mercury. The most commonly recycled metals from household recycling efforts are steel food cans and aluminum beverage cans. Scrap metal recyclers process primarily scrap iron, steel, aluminum, copper, and lead. Other recyclers specialize in higher-value metals like silver, gold, and mercury. Smaller amounts of metals are recovered as part of the purification process in primary metals recycling.
- Q: The metal where they scream the whole song
- Sub type's are quite lots the main ineffective issues ever. i'll tell you the version - there is none. helpful, a die-complicated metalhead will pass on approximately it and all of the tiny adjustments like there is greater orchestral strikes in this one and this one is a sub variety of this one yet with time differences and blah blah blah. relatively, you hear to the two considered one of those genres and you will't hear any distinction (a minimum of i can not). Why can not steel in simple terms be steel, like decrease back interior the 70s each little thing grew to become into in simple terms 'rock'. Even Led Zeppelin grew to become into categorized as rock (although no metalhead will admit). we've Heavy steel, Black steel, dying steel, Thrash steel, middle steel, creative steel, Nu-steel, Deathcore steel, Technical steel, Hardcore steel, velocity steel; or maybe Pirate steel! (No i'm no longer joking). element is, there is not any distinction; lol.
- Q: I dont need to know what metalsjust some of the reasons for alloying metals
- randy rhoads, adrian smith Kreator or Testament or Megadeth not a huge fan i hate glam who knows? old Metallica, otherwise Megadeth b/c new Metallica just sucks balls Bruce Dickinson Dimebag Nicko McBrain Tom Araya Van Halen Maiden never been to one no no no no NO i dont' care for hits, just good music i hated it
