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.

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:whats the best metal songs?
there are many. here is a quick list that i have on the ipod. a good variety of heavy metal and a bunch of progressive rock too. angra (progressive) armored saint (heavy metal) black sabbath (classic rock) children of bodom (black metal) dragonforce (progressive) dream theater (progressive) dream evil (progressive) edguy (progressive) evergrey (progressive) fates warning (progressive) gamma ray (progressive) queensryche (heavy metal/progressive) iced earth (heavy metal/progressive) in flames (heavy/black metal) luna mortis (female vocals)(heavy metal) stratovarius (progressive) helloween (progressive) machine head (heavy metal) megadeth (heavy metal) nevermore (heavy metal) nightwish (female vocals)(progressive) onward (progressive) ozzy (classic metal) pantera (heavy metal) sentenced (heavy metal/progressive) slayer (heavy metal) sonata arctica (progressive) stratovarius (progressive) symphony x (progressive) trans siberian orchestra (progressive/symphonic) although many bands claim the mighty met and maiden as influences. here is a bit of clarification. we all know heavy metal. black metal is a more extreme version of heavy metal. usually coarser sounding vocals. progressive metal is a different animal. the songs are usually longer. sometimes based around a concept. even whole albums based off one idea(i.e dream theater's metropolis pt. 2 or iced earth's the glorious burden) usually extremely proficient musicians. tenor vocalists are the norm. many times they have a lot of orchestration on keyboards. it is not for the faint of heart or mind. you should have a liking of classical music since there is a lot of references to it in there. but if you give some other stuff a chance you will see it is so much better than the crap that most american music is. most of the good metal is coming from europe.
Q:cowboy/western inspired metal?
Neoclassical bands combine metal and classical. Early megadeth is pretty jazzy also
Q:Whats next for metal?
Metals like iron, potassium, zinc, and magnesium are found in the human bloodstream and are needed or else we'd all be dead.
Q:Why do people consider bullet for my valentine not metal?
well these wont be greezy 80s metal bands like more current sexy metal bands the devil wears prada parkway drive my children my bride bring me the horizon in fear and faith the architects johnny truant underminded august burns red evergreen terrace etc. just buy and AP magazine (Alternitive Press) and more southern metal maylene and the sons of disaster mccarthy (local barrie yo) straight reads the line dead and divine eatmewhileimhot! (has some metal/southern breakdowns in , they are quite unique) but not metal . just potent ******* ROCK OUT MAN!! :)
Q:Extraction of metals.?
Bleed from within They arent satanic but the singer does kinda oppose god cause he's had a rough life and lost his mother so gotta understand where he's coming from
Q:POLL: Metal or Rap music?
GnR isn't hard rock, sorry. They were part of a huge genre that lated almost a decade, and while that rock is considered harder than the music you hear today it's not the same thing as ACTUAL hard rock Hair metal's not a bad thing, it just has an un-just bad connotation.
Q:Whats your opinion on Heavy Metal?
Slayer - Thrash Metal Cannibal Corpse - Death Metal Arch Enemy - Death Metal Mötley Crüe - Glam Metal Motörhead - Progressive Metal Deep Purple - Classic Metal Cream - Classic Metal 3 Inches of Blood - Thrash Metal Lamb Of God - Metalcore Mastodon - Metalcore Chimaira - Metalcore Amon Amarth - Death Metal Anthrax - Thrash Metal Dillinger Escape Plan - Metalcore Guns N Roses - Pop Metal Quiet Riot - Pop Metal Ted Nugent - Hard Rock Judas Priest - Power Metal Scorpions - Power Metal Kittie - Nu Metal Krokus - Hard Rock Opeth - Goth Metal Pantera - Groove Metal Ratt - Pop Metal Rob Zombie - Hardcore Sepultura - Thrash Metal Venom - Black Metal Wolfmother - Stoner Rock I should have put them into some order but the info is still there
Q:How did this happen to Metal?
Symphonic Metal!!!!
Q:Can you name all the Sub-Genre's to metal?
Nile Kamelot Death Morbid Angel Obituary Insomnium (early works of) Cradle Of Filth Agalloch At The Gates Kreator Carpathian Forest Entombed Carcass Cynic Dimmu Borgir Bolt Thrower Impaled Agathodaimon Dark Tranquility Leviathan Emperor This is mostly Death Metal, and some Black Metal...
Q:Metal Music?
Saying metal will never die out is like saying music will never die out. You can trace the roots of Metal all the way back to ragtime if you want. As long as musicians listen to music before they sit down and write songs of their own, the different genres of music, including Metal will evolve and move forward in new and interesting forms. The question is not whether Metal will never die out? The question instead is: Will you at some future point find the songs that evolved from Metal to be so different from the Metal that you know and love that you declare it to no longer be Metal by your definition?
