1,Cast Iron Manhole Cover Description :
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.
1.Advantages: Good compressive, bending and impact strenth,anti-corrosion, not rust, long service life
(at least 30 years). The quality meets the same kinds cast ion manhole covers but the cost is 30% lower than. Contain no metal and no recovery value, anti-theft.
2.Applications: water supply and drainage, fire engineering, natural gas,
electricity and telecommunications, street lamp and outdoor illuminations.
3.Designs: based on EN124 standard and according to customer's drawing or samples.
4.Color: black, Grey, green, blue and Marble , etc.
5.Inspection: in-house or the third party as per customer's request.
2,Main Features of the Ductile Iron Manhole Cover:
1. Consequences of temporarily overloading
Temporarily overloading may cause smash of concrete covers, seriously deformation, even slightly split. But this will not happen to FRP fiber cloth manhole cover.
2. Safety options
There is no metal contain, directly reducing potential accident or further maintenance costs caused by thieves. Anti-slip surface offer a safe road condition even in extreme weather.
3. Light weight
Compared with cast iron manhole cover, FRP manhole cover is 30% lighter.
Light weight allows more loading per vehicle, more convenient transportation and economical savings.
Allows a safer working condition, which single workers is enough for installation without risk of injury.
4. Customer design
FRP manhole covers allow customers’ innovative design, logo, or etc. we have our own design team who can also offer design work for customers.
5. No color fading
The cover is not sprayed in surface but painted in whole material so that the color can keep no fading.

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.
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: Why does the surface of stainless steel casting mirror mirror ripple?
- The surface can be improved by a little more than Xiasha
- Q: What are the requirements for casting steel castings?
- 2, the plane should be placed on the following.3, thin parts should be placed below.
- Q: What is the ejection angle of the die casting (Tan Gang)?
- Because after the wax, wax parts will have a slight contraction, which is good for demoulding. Many moulds don't do the ejection angle
- Q: What are the casting parts processing engineering?
- At present, casting processing, according to metal classification, divided into cast iron, cast steel, casting non-ferrous metal.
- Q: Question, such as title, I hope I don't copy the definition of rolling and casting in Baidu encyclopedia, thank you
- The performance is too extensive, I think the following several people all fall into the erroneous zone directly, the performance includes a series of aspects:Mechanical properties: tensile strength, yield strength, elongation and contraction ratio of section and impact toughness after etc.
- Q: What is the casting material?
- The casting material is usually made of gray cast iron, nodular cast iron and vermicular graphite cast iron
- Q: What is the difference between casting and stamping parts?
- Cold stamping is generally no longer done by cutting, or only a small amount of cutting is required. The precision and surface state of hot stamping parts are lower than those of cold stamping parts, but they are better than those of castings and forgings, and the amount of cutting is less.Stamping is mainly based on process classification, can be divided into separation process and forming process two major categories.
- Q: What kind of flaw detector is better for casting parts?
- If you want to detect internal defects, you can use ultrasonic flaw detector, ray flaw detector can also, but the ray of the safety protection level is too high, not recommended priorityMacro Xu flaw detector answered, such as the magnetic particle inspection machine has the demand can contact us, Baidu "macro Xu flaw detection""
- Q: What foundry factories are used in the casting parts of China's major automobile manufacturers?
- For example Changchun FAW, under a casting, two casting and other casting plant, but there are more than half of all outsourcing in Tianjin Hebei Shandong purchase, many automobile enterprises to casting foundry.
- Q: Which master knows how the casting tolerances for malleable iron, gray iron and ductile iron should be chosen? Hurry up, thank youCan you provide a tolerance scale for castings, please?
- Our country has a national standard for casting tolerance levels. This national standard applies to you in malleable iron, grey cast iron, and ductile iron.
