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.

4，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 want to know if cradle of filth is black metal
- Ummm, okorder
- Q: Why does people still refer slipknot as an Nu metal band?I hate it,it`s true that slipknot debut album is rapcore but now,their new album is heavier.What do you guys think???
- Both are good. Rock AND Metal need to stand together against alternative rock...and tear down the over-done Seattle sound that's so early 90's, for God's Sake!!
- 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: What are the different genres of metal? And could you name a band as an example please?I do know some but theres so many people always talk about it gets confusing hahaThanks
- Power metal is the genre that usually has those kinds of lyrics, but genres aren't named for lyrical themes alone; you could have any of those genres with lyrics about mythology and fantasy.
- Q: does anyone know about any good metal/ rock websites that keep you updated on bands, shows, new singles etc. ?????
- Heavy metals are generally considered metals that are dense in the metallic form and they were originally produced inside stars. They reacted with O or S or C or combinations of these as the earth formed. They are in the natural ecosystem. As far as Tasmania, no idea.
- Q: I have noticed that many Death Metal, mostly Technical Death Metal musicians seem to be ICD about how quot;perfectquot; their records sound. Chuck Shuldiner, Mohammed Suicmez, and others. Anyone else?
- This question will require a very long answer. Some important ptoperties are: Metals. 1. Usually solid (except Hg), good conductor of heatand electricity. roduces abang when hit hard, usually very hard, metalic lusture, mellable, ductile, heavy, low IE, form cations,etc. etc. 2. Liberate H2 on reaction with acid, very few react with alkalies, react with nonmetals to form salts, oxides are mostly basic and so on. Nonmetals 1. Usually gases or liquids and very few are solid, low mp and bp, low density, brittle, dull, not mellable, not ductile, etc 2. Combine with netals and nonmetals, oxides are acidic, high electonegativity, high ionization energy, form acids with hydrogen, oxides are acidic, etc
- Q: Listen to these metal songs by Korn and try telling me they are not metal:Korn - ClownKorn - Shoots and LaddersKorn - Ball TongueKorn - *****Korn - Blind
- It all comes down to their chemichal and physical properties.
- Q: It is a fusion of hardcore and METAL. So why isnt it metal? I agree that some metalcore bands are in it for the money, but all bandsgt;
- This is the correct order to play the games in: Metal Gear Solid 3: Snake Eater [PS2] Metal Gear Solid: Portable Ops. [PSP] Metal Gear [NES] Metal Gear 2 Solid Snake [SNES] Metal Gear Solid [Playstation] Metal Gear Solid VR Missions [Playstation] Metal Gear Solid 2 [PS2] Metal Gear Acid [PSP] Metal Gear Acid 2 [PSP] Metal Gear Solid 4 [PS3] Metal Gear 1 and 2 are on MGS3: Subsistance, as extra's. If you wanted to play the games in the correct timeline, this is the order you should play them. Naked Snake [Big Boss] was the star of MGS3 and Portable Ops. You play as Solid Snake in every other Metal Gear game. Metal Gear Solid 3 and MGS Portable Ops took place before any other Metal Gear games, in the 1960's. Every other game takes place in modern times, 1990's up til now. I hope this helps!!

- Q: is it a metal that acts like a non-metal or other way around?
- Magnetism has to do with unpaired electrons. Electrons spin clockwise or counter clockwise. Generally they are paired. When they are not they create magnetism. Iron has 3 unpaired electrons and demostrates tahe greatest magnetism. cobalt and nickle also demonstrate some magnetism. Also, some of the rare earths and some alloys such as Alnico and steel. RECENTLY, several papers have been published on the use of polarized light for revealing the grain structure of metals and alloys. Hone and Pearson1 showed that by examining under polarized light a polished aluminium surface which had been anodized in a suitable electrolyte, the grain structure was revealed, differently oriented grains appearing with different brightnesses. Woodward2, by etching 'Monel' metal in a specific reagent, has found similar effects. Polished surfaces of aluminium and 'Monel' metal, being optically isotropic, do not react to polarized light as do the optically anisotropic surfaces of tin, zinc, cadmium, etc., and the above authors1,2 have attributed the optical anisotropy of the anodized aluminium and etched 'Monel' metal to the anisotropic properties of the surface film formed during anodizing or etching. Although this explanation may be correct, there is a possible alternative which involves the surface contour of the specimen, for it is well known that if pearlite is examined under polarized light no reaction occurs unless the specimen is etched. This has been shown convincingly by Baeyertz3 to be due to the presence of fine parallel grooves on the surface, formed by etching away the ferrite and leaving the cementite lamell? in relief. Furthermore, Jones4 has shown that polarization effects can be produced by deeply etching a metal surface.
