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.

5FAQ:

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:What are some of the advantages of recycling metal?
Oh no....A metal combined with oxygen gives a metallic oxide. For example: 4Na + O2 --> 2Na2O Another one: acid + base --> salt + water This is a double-displacement reaction (neutralization, to be more exact). metallic oxide + water --> metallic hydroxide CaO + H2O --> Ca(OH)2 :)
Q:Alternative Metal bands?
I like some Glam metal. I think the current generation doesn't seem to hate Hair metal with a passion, they/we seem to respect it as classic stuff So I kind of wonder if one day my future kids will respect the Asking Alexandrias and whatnot of today as classics, even though right now metal elitists are like ZOMG THAT SIHT SUX!!!
Q:Is Kamelot progressive metal, or just power metal band?
Some of my favorites... Death Metal: Between the Buried and Me Cannibal Corpse Carcass Morbid Angel Napalm Death Sacred Reich Shadows Fall Vader Glam Metal: Autograph Def Leppard Motley Crue Ratt Skid Row Warrant Groove Metal: 5 Finger Death Punch Lamb of God Pantera General Metal: Alice in Chains Black Label Society Black Sabbath Crooked X Dio Godsmack Infliction Iron Maiden Judas Priest Lizzy Borden Lordi Ozzy Osbourne Quiet Riot Rob Zombie Slipknot Tenacious D White Zombie Misc. Metal: DragonForce Melvins Maylene and the Sons of Disaster Nightwish Progressive Metal: Devin Townsend Dream Theater Savatage Tool Thrash Metal (the best): Sodom Overkill Annihilator Anthrax Dark Angel Megadeth Metallica Slayer Sorry this is so long but hopefully it helps!

Q:Who likes heavy metal!?
There is no transparent metal in any phase except the gaseous phase. Other than that, the metal would just have to be thin enough to let light through, or be cross-hatched or something. But no, there is no transparent or even translucent metal.
Q:Easiest metal and hard rock intros, riffs, and solos?
Metal elements are prepared to give up electrons. Non metal elements either gain electrons or share electrons. it's all according to where the element is in the periodic table, and they all want to get an inert gas configuration. That's why metals conduct electricity- because the electrons they give away can move around the lattice. (and why most non-metals don't conduct; because electrons are ll tied up in covalent bonds) Most non metals form simple covalent molecules with low melting and boiling points, wheras metals are mostly solid, since the metallic bond holds together lots and lots of metal ions. If you base the properties on the fundamental facts; electron gain or electron loss, it'll be easier to associate them. And try explaining them to other people. Writing in your own words is a better memory aid then copying.
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.
