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 much is a ton of scrap metal going 4?
First thing is to define the terms. Wikipedia for example defines WASP as a Glam Metal band which is hilarious. Sound wise they were part throwback part pioneer. Glam no, yes they were 80s but very different from what I consider Glam Metal which is what we called poser Metal in the 80s. Glam and Hair Metal are in themselves distinct sub genres of Metal. The Glam boys like Quiet Riot, Poison, Ratt, etc contributed pretty much nothing to Metal. They had some good tunes but as a genre I'm not a big fan. Many of the hair Metal groups did however pioneer styles that heavily influenced later artists to come. Motley Crue for example, Iron Maiden, Whitesnake are some examples of Hair Metal groups that influenced later Metal genres and styles. There'd be no Metalica without some of these groups You can distinctly hear phrasings in many Metalica tunes that harken directly to 80s Metal. Many Metal groups were Metal before there was Hair Metal, Scorpions for example, but in the 80s the Scorps typified Metal and really helped define what 80s Metal was about despite the group having been around since the 60s. Even Deep Purple one of the pioneers of Metal released a Hair Metal style CD in the late 80s early 90s. Alice Cooper was another who tried his hand at Hair Metal with great success for one effort. Metal has many sub genres. There's no real unified Metal scene today. You have the Nu-Metal like Disturbed, Godsmack, etc. You have Death Metal, progressive Metal, Grunge influenced Metal and 1,000 other catagories. Some seem to blur the lines between Metal and Rock or Metal an Jazz in the extremes. Then you still have some old school So yes I consider 80s Hair Metal Metal. I even consider Rap Metal and Severely Jazz influenced progressive Metal as Metal. I also consider Grunge a sub genre of Metal or at the least a very close cousin.
Q:Epic Metal or Power Metal?
...why exactly did you choose baby oil? nevermind, you know there are many many solutions produced solely to bring out the luster of metal? Brasso, Tarn-X, Chromax, etcetra? I'd better suggest you use metal polishing liquids to polish metals.
Q:Is there a difference between Metal/Death/Thrashcore and Crossover?
Death Metal: Morgoth - Selected Killing Heavy Metal: Iron Maiden - Rime of the Ancient Mariner Black Metal: Siebenburgen - Thy Sister Thee Crimson Wed Speed Metal: Helloween - Heavy Metal Is the Law Power Metal: Helloween - March of Time Progressive Metal: Fates Warning - Fata Morgana Thrash Metal: Kreator - Toxic Trace Gothic Metal: Theatre of Tragedy - Siren Hard Rock: Scorpions - Lovedrive
Q:Nu-metal and alternative metal bands?
Here goes: Deep breath! Heavy Metal Metalcore Mathcore Thrash metal Black metal White or unblack metal Folk metal Death Metal Melodic death metal Power metal Sludge Metal Progressive Metal Alternative metal Nu metal (which sux) Grindcore Industrial metal Goth Metal Glam metal Scandanavian death metal Speed metal( there is a diference between speed and thrash metal even though some people may argue) Rap metal(Just as bad as nu metal) Groove metal Doom metal Post metal Neo classical metal Stoner metal Viking metal And I cant breath out.
Q:why do people consider as i lay dying or bullet for my valentine metal?
the Berzerker are Industrial Death Metal, while some of their their music is a **** to play (like downpicking massacre - fun), they aren't really a technical death metal band. check out Psycroptic. The Isle Of Disenchantment and Ob(Servant) are my favourite albums by them iv'e answered the re post of this question and listed more bands and given ya a link to the best metal torrent site i've found wooohoo 2 points.
Q:Metalloids vs true metals?
Electrolysis of the molten compound. As these metals are very reactive you need a very strong reducing system to produce the metal. A cathode is a powerful reducing system. If you try to do a displacement reaction, you would need a more reactive metal than the one you are trying to extract. Even if possible, it would be very expensive and dangerous to handle.
Q:Metal Oxide, Acidic or Alkali?
Metals are weak on holding their electrons so in reactions they tend to lose them to non metals and form ionic compounds in which they are positively charged and the non metal negatively charged. There is the reactivity series of metals and any metal higher than another will displace it from its compounds, reactivity decreases from top to bottom.
Q:What is the difference between Progressive Metal and Heavy Metal?
to go with the guys above, certain nonmetals, like refractories, can be used at high elevated temperatures. Nonmetals give different electrical properties than metals and need to be used over metals.
Q:What metals are recycled?
Deicide - Scars of the Crucifix Deicide - Bible Basher Slayer - Reigning Blood
