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:metal bands with in between vocals?
Different metals have different properties which make them useful to humans, for doing a wide range of things. Shininess: metals such as bronze have been used as mirrors for thousands of years. Also, shiny things are attractive, so metals have been used for decoration and jewellry. High melting and boiling point: Some metals such as tungsten, have very high melting and boiling points. These are useful in places where you need metals which can stand a lot of heat, such as in smelters and boiler and such. Malleable: some metals such as copper and gold are very malleable: this means they bend and flatten easily when hammered or otherwise compressed. Very useful for coating things (a small amount of gold can be used to coat a large area: very useful for decorating buildings and statues and such!!), and anywhere you need a flexible metal. Also, malleable metals can be formed easily into all kinds of useful tools just by using a hammer and an anvil - blacksmiths use this property of metals to great advantage, to fashion useful tools and implements. Ductile: Ductibility is the ability of a material to be stretched into wires: copper, gold, aluminium, steel, etc. Wire is essential for electronics, which our civilization depends upon heavily. Ductibility can also be used to make things like nails: just stretch a piece of metal into a long, thick wire and cut it at reagular intervals and flatten one end: viola, nails!! Sonorous metals: for music, especially bells and brass instruments!!
Q:Your least favorite metal sub genres?
I like Thrash Metal better but Hair Metal has a few good bands that I like.
Q:Why is metal always cold?
the only good heavy metal band is Metallica.
Q:Who likes hair metal?
Metals- ususally solid- form cations (+)- usually hard-malleable/ductile-conduct electricity and heat-must lustre silvery (except gold, and copper)-many magnetic - on the lleft side of the (staircase)*mettaloids section on periodic table Non Metals- Make anions - on the right side of staircase (ex- Chlorine, Fluorine,Sulfur, Phosphorous....) - opposite of metal characterisitcs...
Q:does metal amplify sound?
cattle decapitation at the gates cannibal corpse black dahlia murder carnifex the red chord job for a cowboy thy art is murder hate vader tsjuder incantation napalm death pig destroyer decapitated morbid angel
Q:Why some people says the real name if heavy metal is metal?
This is a bit confusing but metalheads do not consider older metal bands to be the only real metal. I think what makes it confusing is that a lot of them don't consider the more popular poser bands to be metal (i.e. Avenged Sevenfold, Bullet For My Valentine, Disturbed, Killswitch Engage, Slipknot etc.) typically bands that fall into the subgenres of screamo, emo, metalcore, deathcore, nu metal and so on. However bands that fall into the categories of death metal, black metal, thrash metal, progressive metal, doom metal and the like, they do still consider to be real metal. Personally I could care less whether people consider poser bands to be metal or not, I just don't listen to them so it doesn't really bother me. I also consider metal and rock to be two separate genres today, yes metal did get its start as a subgenre of rock, but it has just evolved and changed so much over the years that there aren't many similarities anymore. It would be like comparing humans and apes, just because humans are a branch off of apes doesn't mean they are the same. Just compare Nickleback to Nile and tell me they both fall under the same genre.
