Product Description:

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.

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. These covers are the T1G3, CLKS 450SR/46SL, CLKS 450SR and 300SR.

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. We also offer spring and gas assisted lifting.

Q:questions for metal fans?
Oldschool punk and metal are equals, don't forget your history. If it wasn't for punk, death/doom/black metal would have stayed in the underground and would have never gotten popular.
Q:Metal Gear??? Otocon & Rex?
Extracting a metal from a metal oxide IS reduction. Why? When it's part of an oxide, the metal has a charge (a metal oxide is an ionic compound). For instance, in MgO, Mg has a +2 charge and O has a -2 charge. In Al2O3, Al has a +3 charge and O is again -2. When the metal is extracted, it has NO charge. So if you extract Mg from MgO, Mg goes from a +2 charge to a 0 charge by gaining electrons ... that's reduction. At the same time, oxygen goes from a -2 to a 0 (the element O2 is formed) by giving up 2 electrons ... that's oxidation. In removing Al from Al2O3, Al goes from a +3 charge to a 0 charge. Again, that's reduction. Oxygen is again oxidized.
Q:What is the difference between progressive metal and metal.?
Metal isn't dead at all, the old, traditional, classic metal bands are still awesomely well respected and Metal is more popular than ever before, hence why their trying to make it a religion. It might not be blatantly obvious in the charts and what not, but damn, it has a huge amount of dedicated die hard fans and always will do. Indeed, their are an insane amount of terrible bands claiming to be Metal when they clearly arnt, but these are simply a phase, this is obvious because bands such as Iron Maiden are still amongst the biggest bands in the world. For example, in the 80's 'Glam Metal' was considered to be wannabe Metal, bands such as Poison and Warrent were classed as a disgrace. Theirs always going to be developments on genres, we wouldn't even have Metal if their wasn't. Chin up dude, theirs so, so many fans defending the faith. Its bigger than ever. (and yeah Metal started in the 70s, arguably with Black Sabbath being the first)
Q:What metals can become magnetised?
Q:Are covalent bonds formed with metals or nonmetals?
Progressive Metal, Progressive Death Metal, Melodic Death Metal, Technical Death Metal, Folk Metal, and Viking Metal. It's a 6 way tie haha. BQ: Dream Theater, Tool, Opeth, In Flames, Dark Tranquillity, Insomnium, Omnium Gatherum, Nile, Decapitated, Obscura, Meshuggah, Bathory, Venom, Death, Cynic, Atheist, Ensiferum, Agalloch, Between the Buried and Me, Metallca, Megadeth, Slayer, Testament, Kreator, Pantera, (Early and New) Machine Head, Black Sabbath, Judas Priest, Iron Maiden, Accept, and so many more I cannot even begin to name! BQ2: Great BQ3: You too man.
Q:What is the strongest metal?
Good luck with that. I haven't met one female that likes metal.
Q:extreme metal v.s core metal?
Metal is more heavier then rock, and the pace of the song can be more faster. Metal is more aggresive then rock!
Q:Is System of a Down heavy/death metal?
i've got b3een into metallic for 15 years and that i nevertheless do not understand what the hell sludge metallic is, a trouble-loose thought of the genres is unquestionably all you %, here is my rapid handbook. dying metallic: blast beats and cookie monster vocals, Cannibal Corpse, Decapitated, early Cryptopsy. black metallic: shrieking banshee vocals, sounds sort of medieval if it incredibly is clever, quicker than dying metallic, examples, Elite, Emperor, Borknagar, early Dimmu Borgir thrash metallic: decrease back interior the 80's there became into basically 3 varieties of metallic, heavy/potential metallic like iron maiden, hair metallic like poison, and thrash metallic like slayer, anthrax, metallica, megadeth etc. potential metallic: see previous answer, additionally, potential metallic many times has operatic vocals, human beings used to shaggy dog tale that to realize potential metallic variety vocals one had to tightly squeeze ones balls, Iron Maiden, Jag Panzer, Blind father or mom there is so a lot extra yet that's sufficient to get you all started, only be careful of stupid expressions like technical brutal melodic and innovative if a sort of adjectives comes in the previous the type call, like Technical dying metallic, it only potential that that's dying metallic which sounds technical/progish/melodic/etc, and comparable factor with the different variety, like melodic black metallic or innovative thrash or some junk like that, human beings abuse those words somewhat in many cases to purpose and sound sensible or something.
Q:Metal... Not Metal?
I like Nu Metal some of it is really off and popping, all really dope **** that is off the hook and people hate for no ******* reason. Let the haters hate, **** them. **** those *******. Ironically, Black Metal is a huge ******* pose, everything about that genre, way more than Nu Metal. I could say the same as Death Metal, since 90 percent of the listeners would never kill someone in their lives. Way much of bigger pose than Nu Metal ever was. By the way, Rob Halford was gay, does that mean all Metal fans are gay? no. So stop assuming everyone who listens to Nu Metal only wears big pants, has spiked hair with frosted tips/dreadlocks, only wears addidas clothing, wears red caps, looks like Eminem with bleached white hair, only wears Hip Hop clothing, etc.
Q:Im bored) tell me your favorite metal albums from these sub genres.?
Uhh, I just listen to metal period, sooo, kinda don't know how to categorize, but I'll do my best. Death Metal-Mushroomhead Black Metal-Cradle of Filth Melodic Death/Black-Nightwish Viking/Folk Metal-None Thrash Metal-Hatebreed Count? Heavy Metal (pre 80's) Black Sabbath or Iron Maiden?? Hair Metal- Never knew such a thing Power Metal-Have to go with Dragonforce on that one lol. Stoner/Sludge-None Progressive Metal-None ADDED Heavy Metal (90's and today's): As I Lay Dying Punk Metal-Bullet For My Valentine Industrial Metal-Rob Zombie Whatever works I guess. Good luck finding some good stuff.
