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.
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,Main Features of the Ductile Iron Manhole Cover:
1. High load capacity & resilience
Hardness is same as cast iron, while FRP manhole covers have overwhelming advantages on resilience recovery. They are designed to exceed A15/B125/C250/D400 load capacity, according to EN124: 1994.
2. Designed structure & pressure dispersion
Arc-shaped bottom structure allows the pressure they bear disperse averagely on the whole surface. Besides, the products are made not by SMC, it was put in several layers of fiber cloth to enhance the structures. So they are stronger than SMC composite manhole covers.
3. 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.
4. 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.
5. 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.

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: There is a little trace of polishingShock polishing is even worseElectrolysis can not be uneven, there is a slight bump
- Use the vibrator to polish the material: the high aluminum porcelain 4cm (with a polishing agent that has an automatic mending function), you go find this polish,
- Q: What is normalizing, annealing, tempering, quenching? What is the difference between forging parts and casting parts?
- For the nodular cast iron, the hardness, strength and wear resistance are improved, such as used in the manufacture of automobile, tractor, diesel engine crankshaft, connecting rod and other important parts. A normalizing and hypereutectoid ball annealing before, can eliminate the mesh two cementite spheroidizing annealing, to ensure that all spheres of cementite. Annealing is a metal heat treatment process, which means the metal is slowly heated to a certain temperature, sufficient for a long time, and then cooled at an appropriate speed. The purpose is to reduce hardness, improve machinability, eliminate residual stress, stabilize size, reduce deformation and crack tendency, refine grain, adjust microstructure and eliminate tissue defects. Its purpose: (1) reduce hardness and improve machinability; (2) eliminate residual stress, stabilize size, reduce deformation and crack tendency; (3) refine grain, adjust microstructure and eliminate tissue defects. In production, annealing process is widely used.
- Q: Domestic large steel castings factory which is better, recommend!
- At least spend money on research and development, then the quality should be all right.
- Q: How much is the amount of electrophoretic paint per square meter used in the casting?
- It was a very simple question, and it was complicated by what you said.
- Q: Question, such as title, I hope I don't copy the definition of rolling and casting in Baidu encyclopedia, thank you
- Service performance: heat conductivity, friction reduction, shock absorption, heat resistance and corrosion resistanceTo compare these properties, it depends on the specific material, structure, and use of the parts. Otherwise, there is no comparisonS
- Q: What are the causes of pitting on the surface of a precision casting?
- The quality of the shell surface is out of order. Or shot blasting out of question.
- Q: Why should pig iron be used in casting?
- Not necessarily is iron, steel, stainless steel, aluminum, copper can be cast iron, is cheaper, and better properties of cast out, for example, is not easy to rust, high strength, easy processing and so on, and is the only iron iron cast out, it is not necessarily the raw pig iron, plus some other material
- Q: When the blank is a casting, the margin is evenly distributed, how should rough machining?Please help friends from mechanical classes.There is another problem: in the NC milling plane contour machining, when the rough margin is large, how to deal with.Who can help in time, add 20 reward. Urgently!!
- Even distribution is a good thing. Generally, the machining allowance of the casting is uneven.If the processing depends on how your processing techniques have been arranged.In the NC milling plane contour machining, when the rough margin is large, how to deal with.1. Return to the foundry, too large margin improvement.2. Then you can spend more time on it.
- Q: What reason is the bronze statue choking fire?
- The casting process in boiling phenomenon, is the setting of the exhaust hole positioner position or number is not reasonable, the air cavity can not be discharged, overwhelmed by a material inlet, reflux, change mould, sincerely help you look forward to adopt,
- Q: Is 316 casting better than 304 casting?
- It is comprehensive. There is no simple comparison of the material to determine the degree of difficulty in processing
