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: I don't exactly know what is Speed Metal. Can you please explain me what defines a song to be quot;Speed Metalquot;..or is every Metal song automatically rated as Speed Metal when played at high tempo?At first I thought it was just Heavy Metal with high tempo in guitars and drums.But than I came across to some songs that I thought were Speed Metal but they are rated as Thrash Metal at high speed.Also I noticed two styles of supposed Speed Metals bands.1) Motorhead: Sounds like Punk-Rock mixed with Heavy Metal and the lead singer's voice sounds masculine.2) Judas Priest: Their music is alright but the lead singer's voice makes it feel like listening to Glam Metal with Heavy Metal riffs at high tempo.Can you please provide me with Speed Metal that has a more masculine voice in it. I'm not really into screams that sound like chipmunk.
- A current is run through the coil, which creates an electromagnetic field. This electromagnetic field is directed in the direction of the coil. If the coil is parallel to the ground, the current goes though the ground and back up. If the current interacts with any metal on the way up, it will give it an electromagnetic field of its own. Different metals create different electromagnetic fields.
- Q: Black metal is never normally really associated with technical skill although there are definitely bands that are more than proficient. Some however seem to stand out abit more, and one of those bands imo is Abgott.
- Nu Metal is one of the worst imo
- Q: Are metals crystalline? Explain.
- Like g had said, when metal had emerged in it's earliest form in the early 70's, it would have been considered a sub genre of rock. I mean when I think of Black Sabbath, I thought of them more as a hard rock band even though they are considered to have had a heavy influence on the Metal genre. But they didn't 'invent' Metal. It's something that progressed of the rock genre the same way Jazz had progressed off of spirituals, ragtime, classical, and brass band or the way the birth of Rock was influenced by jazz and blues. With that being said, although Metal being influenced heavily by 70's hard rock, it really is a genre of it's own. Keep in mind that what sets apart rock and metal is their riffs. It's sort of like rap and hip-hop. They're separate genres but they have similar elements. It's all about how those elements are used. So I would say Metal really is a genre of it's own. Hope I helped. Hope I made sense too xD
- Q: list your 10 favorite thrash metal albums of all time....
- Metal is a good conductor because the molecules inside metal are closely packed together. When heat is passed through the metal (the process of conduction) the molecules are so tightly passed that the heat moves through the metal quickly. D
- 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.

- A transition metal carbene complex is a organometallic compound featuring a divalent organic ligand. The divalent organic ligand coordinated to the metal center is called a carbene. All transition metals form such complexes. Many methods for synthesizing them and reactions utilizing them have been reported. The term carbene ligand is a formalism since many are not derived from carbenes and almost none exhibit the reactivity characteristic of carbenes. Described often as M=CR2, they represent a class of organic ligands intermediate between alkyls (-CR3) and carbynes (≡CR). They feature in many catalytic reactions in the petrochemical industry and are of increasing interest in fine chemicals. The characterization of (CO)5Cr(COCH3(Ph)) in the 1960's is often cited as the starting point of the area,[1] although carbenoid ligands had been previously implicated.
