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 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:role of metals in plants and animals?
Yes, I like alot of metal. My main genre is rock/alternative, but I like pretty much anything. My little brother got me listening to metal many years ago while driving to school. I allowed him 2 of 'his' songs to play while on the way, and it was 'Four Horsemen' by Metallica and 'Sweating Bullets' by Megadeth that got me into it. ;)
Copper is the most used metal in communications. Right now the cost is volitile due to demand by third world countries for infastructure. In small components there is gold and titanium as well as some exotics being used for plating to increase reliability and low resistant throughput.
Q:Hair Bands or Thrash Metal?
they are good conductors of heat.
Q:What the Heck is NU-metal?
Metals form what is called a metallic bond, a delocalised mess of electrons around all the nuclei. This is what give metals their metallic properties. Non metals have positively charged nuclei, and as such will attract electrons and form covalent bonds. I'd go into more details but its been a while since chemistry.
Q:will i need to play metal gear peace walker to understand metal gear solid 5?
Metal Gear online just means that you can go online and battle it out with your friends and such. Really I believe it depends on what platofrm you are using. It would have really helped us out if you had included that, maybe try adding it into the add details section.
Q:Do you consider Grunge to be Metal?
Opeth Dream Theater Tool Between The Buried and Me Russian Circles (instrumental band)
Q:Why are metals insoluble in water?
1) by adding a less noble metal (for example Zn or aluminum to steel), which will corrode faster, meaning will oxidize faster). It's the same principle as in a battery - a more active metal will dissolve faster 2)by galvanization - physical protection by coating a corrosion-prone metal with a protective agent like zinc. Also a layer of paint, enamel, or plastic can be applied.
Q:What are some good 2010 metal songs?
There are as many ways to extract metals as there are metals. It depends on: 1) what form the metal containing mineral is in 2) what is the composition of the metal containing mineral (oxide, silicate, carbide, carbonate, etc) 3) what other metals (impurities) are present 4) how pure does the final product need to be. This is the field of extractive metallurgy. If your project is to cover all aspects of extractive metallurgy, you have laid out a significant project, there are graduate level university programs just on the fundamental processes.
Q:The different sub-genres of metal?
Band names i like Testament, Really badass name Heaven Shall Burn, very bold statement right there Anata, I like how it's kind of beatiful but creepy at the same time Necrophagist, Eater of the dead, what else is as obscure and cool as this? The Faceless, Very ominous sounding band name i like it
Q:different method to extract metals?
Metal all the way. Metal expresses actual emotion, rather than happy pop music, which uses false representations, and exaggerated and untrue emotions and actions.
