Product Description:

1,Cast Iron Manhole Cover Description :

A 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.

5,FAQ:

We have organized several common questions for our clients,may 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. These covers are the T1G3, CLKS 450SR/46SL, CLKS 450SR and 300SR.


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 installed a recessed manhole cover in my garden, filled it with grass but it’s just dying; what can I do?

A. We produce bespoke GrassTops which feature drainage holes and geotextile membranes, allowing the water to drain through and your grass to grow. These are also suitable for other infill materials such as chippings, gravel and suchlike.


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:Tell me What is real metal?
Metals usually have high melting points and high densities. The exceptions are certain alkali metals, but they react with hydrochloric acid (quite violently I might add). So the element is a non-metal (and appears to be phosphorus.)
Q:What is the difference between Progressive Metal and Heavy Metal?
1) as almost all nonmetals are non conductive chance to electro magnetic interference is very low...( so great chance in electronics 2)its conductivity is almost independent of temperature 3)light in weight
Q:What happens if you swallow metal?
Metal Gear Solid 5 is technically two games. Ground Zeroes (the prologue) is set in 1975, a year after Peace Walker. The Phantom Pain (the actual game - Guns Of Patriots is another) is set in 1984, 11 years before Metal Gear. Just play Metal Gear Solid, Metal Gear Solid 2, Metal Gear Solid 3 (Peace Walker), and Metal Gear Solid 4.
Q:POLL: RAP or METAL ?!?!?
To me there's a huge difference between Nu Metal and Grunge. 1. Grunge bands had more of a variety of sounds. Not only apart from other bands but even different sounds within the same band. The was light, shade, heavy, sparse, etc. Nu Metal bands have pretty much one sound and different bands sound similar. 2. Grunge had a lot of power chords, open chords, leads, picking, sometimes all in the same song. Much like 70's bands did. Nu Metal is mostly low power chords. 3. Grunge had a lot of female singers. Nu Metal barely did. 4. If you strip away hip hop from Nu Metal, you get Disturbed. Disturbed is no where near sounding Grunge. They sound Nu Metal without the Hip Hop. I still consider it Nu Metal. 5. I always thought 90's Grunge/Rock was like 70's Rock if you simplified it and added a punk element to it. Nu Metal is like a mix of Korn, Metallica, and Tool except even more simplified. Oh, and Hip Hop too. Something like that anyway. Maybe has an element of Grunge in it too but it not Grunge. 6. Grunge wasn't glam Metal. Glam Metal is like Kiss, Motley Crue, and Poison. Grunge is what put those stupid bands out of style. Grnge was a lot more Punk and had elements of 60's and 70's Rock.
Q:Is System of a down considered metal?
play them all, even the old school ones
Q:POLL: Heavy Metal or Rap?
It's a gas, honey. Are gases metal or metalloid?
Q:Black metal extinct!!?
I think that metal falls into the rock catagory. With out Rock 'n' Roll there would be NO metal! Both are awsome because the writers have talent. There is to muc cRAP out there today and not as many actual musicians.
Q:CHEM : Metals and Non-metals = Doubts!?
Viking metal is a sub-genre of Black metal, and people already talked about the lyrics. But I just wanted to point out that, yes, Amon Amarth (my favorite band if I must add) does sing about vikings and has lyrics about Norse paganism and mythology, but I though I would just state that even the band members don't consider themselves viking metal. So in my opinion, I just call them Melodic Death metal, but everyone has different opinions.
Q:What kind of heavy metal do you listen to ?
Check out Nightwish's first two albums, Angels Fall First and Oceanborn, seriously leagues above the newer albums with the new vocalist.
Q:isnt 5fdp heavy metal?
they're probably named this because of the fact the gang IIA metals style steel oxides that react with moisture to style bases. Soils that incorporate those bases are reported as being alkali or alkaline.
