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

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:Whats the difference between black metal and death metal?
Prog is steeped in lots of scales, different time signatures throughout the song, and lyrics of more thoughtful subjects. Where as metal can have those exact same qualities, most metal songs don't last 7-10 minutes on average. Prog Metal can also be said to be pretentious at times. There can be a lot of argument regarding this subject.
Q:Who knows of any modern metal bands who are actually good and don't worship the devil?
Death Metal
Q:Thrash Metal?????????
metals are strong and nonmetals are weak
Q:are there any blue metals?

Q:is symphonic black metal Real black metal?
I like black metal more, because you can incorporate a lot more elements into it than in death metal, plus I'm not a fan of death growls (although there is one death metal band I like: Cannibal Corpse). I'd have to say my favorite black metal bands are Dimmu Borgir, Satyricon, and Gorgoroth.
Q:Does gorilla glue work pretty good on metal?
Is Hydrogen A Metal
Q:extreme metal v.s core metal?
Linkin Park, and Three Days Grace are most certainly not metal! they are maybe rock metal is FAST DISTORTED RIFFS... a good example of that is parkway drive they are metal
Q:What is the order of reactivity of hydrogen, metal X and metal Y?
volume of unknown metal = volume of water and metal - volume of water =23.4mL-15mL=8.4mL=8.4cm^3 Density of unknown metal =mass of the unknown metal/volume of the unknown metal=8.27g/8.4cm^3=0.985g/cm^3
