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.

·High endurance

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:gold from metal?
Q:Rap or Metal?
Yes. 'Rust' specifically means iron oxide. All other metals oxidize, but only metals that contain iron can 'rust'.
Q:What are your favorite sub-genres of metal?
Heavy metal is not a bad enemy anyway. I play for an all-girls-in-bikinis rock band called Charlotte Murphy as the lead guitarist and backing vocalist.
Q:Do pure metals form crystals?
Metals, in general, are malleable and ductile; they are good reflectors of optical radiation and good absorbers of longer-wave radiation such as microwaves and radio waves; they are good conductors of heat and electricity. They form positive ions in combination. Most metals combine fairly easily with other (nonmetallic) elements; metals can dissolve in each other to form alloys.
Q:Metal Gear Solid - Should I play the first two Metal Gear games first?
3 Examples of metals which are used to coat other metals would be Gold, Chromium, and Zinc. Gold is used to coat other metals for a couple of reasons, 1) Gold is a ‘pretty’ metal which people will pay money to have things made of. But Gold is also an expensive metal (several hundred dollars per ounce), so one can get the same visual effect of having a gold ___ if it is just gold-plated and not solid gold, thus making it cheaper. 2) Gold is a chemically inert metal; it will not react with many things, and also has a very high electrical conductivity, so coating some other metal with gold will improve its chemical resistance to corrosion and lower its electrical resistance. Chromium metal is used to coat other metals for similar reasons, --Chromium is less reactive than many other metals so one can “Chrome-plate” a more reactive metal with Chromium and help protect the metal from corrosion. For example, many car’s have ‘chrome-plated’ bumpers. is --Also, Chromium is a visually appealing metal so having a nice shinny Chrome-plate bumper is considered more desirable than a rusty old Iron bumper. Zinc metal is used for a much different reason, --Zinc is more chemically react than most other metals and is not a particular pretty metal either. Zinc is often used as a sacrificial metal to help protect other metals. For example, many things like nails, screws, washers, …., are Zinc-plated to help protect those [Iron] parts from rusting. The Zinc will oxidize before the Iron, thus protecting the Iron at the expense of the Zinc.
Q:Metal/Nu Metal Songs 10 points for be best selection.?
Depends on the metal and the state it is in. Alkali metals burn very rapidly, whereas metals like titanium and tungsten will not burn unless they are heated very strongly in a source of high oxygen content.
Q:what is heavy metal music?..............?
id leave the legs alone metal is not meant to be stained try spray paint or metal paint for the legs. dont be afraid to call home depo or lowes
Q:Reactions of acids with metals?
1. I would like to say that i absolutely LOVE THE LORD 2. I also must say that i absolutely LOVE METAL. I do not like alot of Grindcore, Deathcore, or Black Metal because the LYRICS can be very VULGAR. Not because the MUSIC is EVIL. However, i really love the band DEATH. My favorite Subgenre is METALCORE. My favorite metalcore Bands are all Christian: -August Burns Red -Underoath -Becoming the Archetype I love metal, and I think that Christians can display and evangelise about their faith in the Lord, and their lifestyle THROUGH they're music. Whether its traditional Praise and Worship, or metal.
Q:I want to get into metal?
Q:Do you prefer metal or pop?
I like some death metal bands, though Im actually more into the symphotic metal genre (things like Nightwish, Epica,Sirenia, etc.) I've never really been big on thrash metal though, but maybe its just because I havent listened to the right bands. :-P
