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:How many parts does Metal Gear Solid has?
Heavy metal definetly. But some alternative is okay. Q101 is the greatest radio station ever :P
Q:identity of metal question?
Technically Satyricon, Decide, Gorgoroth, Impaled Nazarene and Behemoth are all Black Metal bands. Dimmu Borgir is symphonic black metal. and also I think it is disgusting to even mention Green day and metal in the same sentence (that goes for Bullet for my Valentine too) -shudders-
Q:A question for heavy metal fans only?
All metals can be made to shine. It is not the structure of the base metal which affects the shine over a period of time. It is the oxide layer which forms on the surface. The more active the base metal, the thicker and looser in general the oxide layer. Think iron and red rust. You can shine a piece of iron to a very shiny mirrorlike surface and within a relatively short period of time, the surface will oxidize and the shine will disappear to be replaced with loose red rust. The amount of shininess of the surface of any metal is determined by the oxide layer on the surface, the thicker, the more it obscures reflections from the base metal, The thinner, the more reflected light shines through. Passive metals such as gold, develop an oxide layer but it is tightly cohesive and very thin, which acts to separate the base metal from the environment while being thin enough to allow a significant amount of light to be reflected off the surface so you see the yellow color of the gold. Red rust on the other hand is loose, and does not separate the base metal from the environment so it continues to oxidize and corrode the base metal. Alloys such as stainless steel are passive because of additives which form the oxide layer. In the case of stainless steels, it is chromium, which forms a tight cohesive oxide layer before the steel itself starts to rust. The chromium dioxide layer being tightly cohesive like gold, separates the steel from the environment so it stays shiny.
Q:Black Metal vs. Death Metal?

Q:Finnish Black Metal Bands?
Q:Anime about extreme metal?
Metals are malleable, ductile and sonorous...They have a metallic luster...and are electrically conductive.. On a chemical note metals..metals react with oxygen to form oxides..metal oxides are basic and neutral in nature..metals react with water and produce a metal oxide and hydrogen gas or metal hydroxide..metals react with dilute acids to give salt and hydrogen.. On atomic note, metals lose electrons and become positively charged ions and are called as cations..
Q:What is black metal about ?
Metal and rap often fight as to which is a more talented genre of music. I dont like rap in the least but I do admit there is talent involved in the genre. I am a lifelong metalhead and listen to mostly thrash, but also black metal and death metal. I think metal listeners mostly fight with each other as to which subgenre of metal is better. For example Nu Metal (terrible stuff... eg, Slipknot) verses Thrash ( True Metal... eg, Slayer)
