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:Least favorite Thrash Metal?
Black metal is an extreme subgenre of heavy metal. It often uses fast tempos, shrieked vocals, highly distorted guitars played with tremolo picking, blast beat drumming, and unconventional song structure. Death metal is an extreme subgenre of heavy metal. It typically employs heavily distorted guitars, tremolo picking, deep growling vocals, blast beat drumming, minor keys or atonality, and complex song structures with multiple tempo changes. Thrash metal is a subgenre of heavy metal that is characterized by its fast tempo and aggression. Thrash metal songs typically use fast, percussive and low-register guitar riffs, overlaid with shredding-style lead work. Thrash metal lyrics often deal with social issues using direct and denunciatory language, an approach which partially overlaps with the hardcore genre. Neo-classical metal is a subgenre of heavy metal music that is heavily influenced by classical music. It refers to a very technical performance consisting of elements borrowed from both classical and heavy metal music. Yngwie Malmsteen, the most notable musician in the sub-genre, contributed greatly to the development of the style in the 1980s. Progressive metal (sometimes called prog metal) is a subgenre of heavy metal, which blends the powerful, guitar-driven sound of metal with the complex compositional structures, odd time signatures, and intricate instrumental playing of progressive rock. Many progressive metal bands are also influenced by jazz fusion and classical music. Like progressive rock songs, progressive metal songs are typically much longer than standard metal songs, and are often thematically linked in concept albums.
Q:What exactly is the definition of Death Metal?
Basically, metal that was formed to bridge progresstive rock with metal, stealing the traits of both. It is more deatiled than ordinary metal, with odd time signatures that provide a unique effect. Read the article:
Q:R&P: What is your favorite obscure metal subgenre?
I'll answer the latter first. Metal is...well, without a better explanation for it...just Metal. Often considered to be pioneered by Black Sabbath, this genre has now evolved into many and many subgenres, including Death, Black, Power, and Progressive Metal. >_> *Note: I wouldn't say genres are meant to be subjective, at least not to the degree that anyone can claim anything to be Metal. There are certain defining characteristics to it, which can be interpreted loosely, but only slightly. Heavy Metal usually has two different meanings: 1. The proper term of 'Metal' is actually 'Heavy Metal'. Many use Heavy Metal in the same context as Metal. 2. It's also used to refer to Traditional Heavy Metal, like Iron Maiden, Judas Priest, and Accept, and modern bands that have the same sound (often clones). 3. Screamo is on a totally different tangent, it's a subgenre of Punk. I'll leave someone else to give the details of that, since I am not experienced. Now, my recommendations are divided by subgenre: Power: Helloween, Kamelot, Stratovarius, Sonata Arctica, Angra Progressive: Adagio, Winds, Symphony X, Pagan's Mind, Dream Theater. Melodeath: In Flames, Dark Tranquillity, Unanimated, Eucharist, At the Gates. Death: Monstrosity, Death, Necrophobic, Illdisposed, Edge of Sanity Black: Immortal, Catamenia, Stormlord, Dissection, Emperor Sludge/Stoner: The Ocean, Electric Wizard, Superjoint Ritual, Kyuss, Isis Gothic: Tristania, Sirenia, Orphanage, The Black League, Dark Lunacy. Doom: Candlemass, Grand Magus, Isole, Draconian, Novembers Doom Folk/Viking: Ensiferum, Eluveitie, Borknagar, Vintersorg, Windir Traditional: Iron Maiden, Judas Priest, Saxon, Black Sabbath, Accept. Thrash: Kreator, Holy Moses, Testament, Sodom, Coroner. Avant-Garde: Alchemist, Faith No More, Solefald, Unexpect, Maudlin of the Well.
Q:Metal + water (H2O) -> what?
I'm not really picky when it comes to metal. I listen to both, and don't really consider either the ultimate music. As for which is more evil, it really depends. Even black metal has a couple of different sub-genres, Norwegian black metal being the only one I would really consider evil. Of course, most Norwegian black metalists worship the devil (it's a proven fact). I wouldn't really consider either genre really dangerous. Biased answer though, been a die hard metal fan for years. And I'd say that both are pretty irritating to normal people.
Q:Reacting hydrogen and metals?
Well, we happen to know that the metal in Drano is aluminum. To identify the metal, I would isolate the pieces of metal and measure the density. Most people think that the aluminum reacts with the NaOH. Actually the NaOH dissolves the oxide coating that covers the aluminum metal. Once the Al2O3 is dissolved, the aluminum metal reacts with the water to make aluminum hydroxide and hydrogen gas. Al2O3S) + 6NaOH --> 6Na+ + 2AlO3- This exposes aluminum metal which reacts with water: 2Al + 6HOH --> 2Al(OH)3(s) + 3H2(g)
Q:Metal by Numbers Lyrics?
The ballast (transformer) is intended for specific lamps. high or low pressure sodium lamps will not work in a metal halide fixture and so on.
Q:What is metal music anyway?
The surface of the sun can go beyond burning metal, it can melt and vaporize all metals with no problem.
Q:What is viking metal?
Well I'm really into the Scandinavian Christian Extreme Metal scene, pretty big on Norwegian Black Metal, and also into Finnish Folk Metal.
