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.


2,Main Features of the Ductile Iron Manhole Cover:

·High endurance

·High Strength

·Pressure Resistence

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:Sooo.How are people suddenly getting all these stupid Metal Genres?
hair metal, all what grunge did was destroy some good fun rock music and it brought in some of the nu metal garbage and some of the angry rock bands, the hair metal bands were all about fun and good music that is easy to the ears :)
Q:What happened to metal?
They are nothing but d-block elements in periodic table
Q:is metal toxic to parakeets?
Well, iron is a metal that doesn't contain carbon. Both are elements i.e. substances that can't be broken down into simpler substances by a chemical reaction. Most of the known elements in the universe are metals eg. aluminium, gold, copper, but the non-metals are more abundant eg. oxygen, hydogen. They are termed metals because of their structure and the way in which they bond to other elements. Maybe by metal you meant metal alloy. Steel is an alloy (mixture) of iron and carbon. I think all alloys of iron have some carbon in them. Don't know if this is what you meant but it was good trying to think about an answer.
Q:***is it a metal or non metal? ****?
ALKALI metals: - 1 valence electron, so highly reactive - soft metals - silvery in color - low boiling and melting points - large atomic radi ALKALINE metals: - have 2 valence electrons, still very reactive - shiny, silvery-white colour - when heated in flame, Mg gives a brilliant white flame, Ca a brick-red, Sr a crimson, and Ba an apple green - harder and denser than sodium and potassium, and have higher melting points - found combined with oxygen and other non metals in earth's crust TRANSITION metals: - are electric conductors - have luster - malleable - most are hard solids with relatively high melting and boiling points - because of unpaired d electrons, they can have oxidation numbers of +4, +5, etc.
Q:Songs that define these genres of metal?
From autumn to ashes. I cant put a name to the genre i like... its wide
Q:What is metal? [20 characters]?
if you knew metal you wouldn't be asking this question, would you? HA! bet you shop at hot topic, too.
Q:If someone who listens to Metal is considered a Metal-Head, What do you call someone that listens to screamo?
look up kill you by dethklok. I'm not sure if it's even actually dethklok, I downloaded it from some sh*tty p2p server, but the intro is a pretty intense drum solo. Also define coolest. Some people who don't know much about music seem to think that fastest = best, which anyone who does know more than two sh*ts about music will tell you is untrue. Lots of metal drummers can play fast, not many can play really well. look up drum jams by Thomas Pridgen(sp?). he's the old drummer from The Mars Volta (not metal AT ALL), or even look up some Mars Volta stuff. His drumming style is really unique, he does things that you wouldn't expect and makes really original music with his kits. Also he can play fast hell. And of course, there's John Bonham of Led Zeppelin, may he rest in peace. check out Moby Dick (the solo starts somewhere in the middle. lasts almost 2 full minutes). he was incredible.
Q:Why is metal always cold?
A Metal category would be a bad idea. People will flood it with crap about slipknot, disturbed and other pop rock crap. But they are tons of Metal forums online. I'd rec Metal archives.
