Product Description:

1,Cast Iron Manhole Cover Description :

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.

·High endurance

·High Strength

We have organized several common questions for our clientsmay 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:Discussion questions about heavy metal?
If you literally mean futures as in commodity futures, pewter is an alloy of tin, lead and other metals and commodities deal entirely with pure metals like gold, copper, steel, etc. If you are stumbling over wanting a company that has a future in the metal or information on its future, you will find that there is very little. It has been almost entirely replaced with Britannia Metal because food holding containers with lead in them are frowned upon and plated metals are cheaper than they were in the past.
Q:Is Deathcore considered real metal?
if your gonna listen to heavy metal try Iron Maiden. The music is good and the lyrics have meaning, the albums Somewhere in Time and Powerslave theyre are excellent and i personally think there the best albums they put out
Q:Best band from each metal subgenre?
Personally, I find a lot to love in either. Favorite glam band: W.A.S.P. Favorite thrash band: Definitely Metallica.
Define metal.... like Escape the Fate or Disturbed or black metal? EDIT: Srry for the late reply. and thx for the rtard who thumbed me down. I don't think you trust in my... self-rightous suicide. I... cry... when angels deserve to die... Awesome quote. Chop Seuy by System of a Down. (Its nu-metal but it sounds really metal-like to me) Let the bodies hit the floooooooooooooooooooor! Bodies by the Drowning Pool. I think the singer died or smth. :( A certain girl, she took my hand and ran it up her thigh... She licked her lips and pull my hair I fell in love for the night... Another awesome quote. Situations by Escape the Fate. (You must get that song if u like emo music) I push my fingers into my eyes... its the only way... so it stops the ache... Duality by Slipknot. Everyone knows this song. I slide... through the wasteland that's my world, my hunger takes your life, preyed on to keep me alive... Mercy's all that you need, mercy is empty in me... Sidewinder by Avenged Sevenfold. Awesome song, especially the acoustic part. Toyota Fujitsu Sashimi Honda... WHATS UP PEOPLE!!!!!!! Whats up, people by MAXIMUM THE HORMONE. A japanese band, I got no idea what they are saying but they sound awesome.
Q:Is adamantium a real metal?
okay, then. Waking the Cadaver Ratt Despised Icon DevilDriver Carcass Exhumed Whitechapel Impending Doom Dokken Aborted you never said no deathcore and no goregrind :3
Q:Wood bat vs. Metal bat?
Q:What types of ''Metal'' do you like best out of the following?
Hmm...this is the major problem these days. And it just doesn't end with hair metal, nu metal, and metalcore. Bands like AC/DC, Alice in Chains, Soundgarden, Guns N' Roses, Rage Against the Machine, even Nine Inch Nails on their Broken album, have been labeled metal countless times. Now, with regards to hair metal stuff, some like early Def Leppard, Motley Crue can be considered metal, but would one even dare to call something like Poison, Warrant, Bon Jovi metal? Bands like Guns N' Roses and Van Halen fall into metal a little bit, but for the most part, both bands stay as hard rock bands. Alice in Chains's first album Facelift was more closer to heavy metal. On Dirt, just a few tracks are heavy metal and the rest are hard grunge rock and on the third album, it's pretty much hard rock. Now to the nu metal case. I always considered bands like Evanescence as alternative rock. With nu metal, some bands are more alligned to alternative rock...these include Linkin Park, Papa Roach, P.O.D., and Limp Bizkit. However, some are closer to metal than to rock...Disturbed, Mudvayne, Stone Sour, Slipknot, etc...I normally consider them to be metal while bands like Limp Bizkit and Linkin Park are just rock. And for the record, the majority of all metalcore bands are way too heavy. I almost always consider metalcore (and deathcore) bands metal...Killswitch Engage especially.
Q:Name some Metal Rock bands?

Q:Metals???!?!?!?!?! 10 points!!!!!! best!!!?
Everything is fine Katz but you definition of what you called Gore Metal is wrong darls quote Having it’s routes in Goregrind, Gore Metal crosses it with Melo Death Metal and produces what is just a straight up breed of the two sounds. The vocals are clearer and less distorted, but still growled. There is less distortion and more melody to the guitaring and more rhythm to the drumming. Examples– Carcass, Impaled, Carrion. First of all its called GRINDCORE the reason being that its a cross between Hardcore, a bit of Death Metal and some Thrash Metal ..the vocals are clearer? have you heard Napalm Death or Carcass ever? less distortion and more melody to the guitaring? I don't think Carcass is a good example of what you're trying to expose here, Carcass's Symphony of Sickness less distortion more melody ? kidding right? more rhythm at 200 mph to the drumming ok in bands like Napalm Death and Terrorizer Not trying to outshine your knowledge at all I think your answer is great, but Carcass was a band that evolved from Grindcore (they became famous for their unique style) to a more melodic stuff that could not be categorized, perhaps you are basing your answer on Heartwork or Swansong albums, .so I honestly believe Carcass should not be under that category Under Industrial Metal you forgot to mention some of the most important exponents of this genre Laibach Godflesh Just trying to help Katz, please dont take it personal.. : ) Cheers
