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.

Specific Heat Capacity Of Metals
Q:Grunge or Heavy Metal?
Prices change hourly as commonly used precious metals are bought and sold. 20 minutes ago, platinum was selling for $1053/ounce, rhodium for $1050/ounce. Those two metals are used in catalytic convertors for cars.
Q:What is metal music anyway?
look for the solar power plant in spain (maybe near madrid) ... it has a lot of mirrors around the ground with the light focused on a tower in the middle of all the mirrors this tower uses the heat reflected from all the mirrors to heat water to power a steam turbine im sure i heard that the tower had to be constructed taking into account that metal will melt up there also most of the more powerful telescopes (ie the biggest ones that NASA use) if you put some thin metal in the Focal point it will melt ive seen it with my own two eyes enjoy
Q:About Metals.Why is it good that metals are shiny?
When metals are taken out of the earth, they are usually found in ores. In the process of purifying the metal, it is smelted. For example, iron. When iron is smelted sulfur dioixide is a by-product. It is released into the atmosphere and causes acid rain. The acid rain plays around with the pH balances in the environment. For example, it can decrease the pH of soils making them unable to support plant life. It can also lower the pH of aquatic environments. This can kill organisms such as fish - thier larvae is killed by slight pH changes - therefore acid rain disturbs the ecological niche.
Q:What makes a band metal...?
Don't use plural terms when you're referring to metal. I thought you were asking a science question for a second, haha. Its THRASH not TRASH by the way. Unless you're a fan of black and death metal, they're both gonna sound the same to you.
Q:What are Your top Metal bands?
Eaither: Enter Sandman- Metallica Creeping Death- Metallica Sonne- Rammstein Ace Of Spades- Motorhead Can I Play With Madness- Iron Maiden Ozzy Osborne- Crazy Train
Q:Why do Metals...?
From your list of Old - only metallica! From Nu-metal list - all groups! =)

Q:why people think the Metal Gear Series is called Metal Gear Solid Series?
I don't really like nu-metal. My brother goes crazy for it though, he's trying to get me to like it too. So far, the only band that's grown on me is Rage Against The Machine. As for it being 'real' metal...I consider it a branch of metal, but it's a pretty weak branch. @->-->-
