1.Cast Iron Manhole Cover Description :
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.
2.Main Features of the Ductile Iron Manhole Cover:
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.
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.
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. 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 to get rid of casting sand inside casting parts?
- Are you saying that in the sand casting cavity? We use the manual blast, he is like a pipe will be automatic shot out of the grit, into the casting cavity, to remove the internal cavity in the purpose of casting sand!
- Q: In theory, which is more expensive, forging parts or casting parts?
- It depends on the structure. In theory, the shape of the forging is relatively simple, but the requirement of internal structure is relatively high
- Q: What is the reason for 304 stainless steel precision casting parts to be changed?
- Mainly because of the cooling shrinkage caused by internal stress caused. There is the change of temperature distribution in materials element imbalance, is typical of surface and internal, thin wall and thick wall, bottom and top.
- Q: The difference between cement sand castings, resin sand castings and vacuum casting parts
- The clay wet sand castings casting weight from a few kilograms until tens of kilograms, but the clay dry type of casting production can be weighed dozens of tons.For medium and large castings, cast iron, cast steel can be self hardening sand with resin can be water glass sand production, can obtain the precise size, smooth surface castings, but casting precision, surface roughness, density and microstructure, mechanical properties and material cost of sand casting production is often poor, so when the higher performance requirements of castings, should adopt other casting methods, such as casting (lost wax casting), die casting, low pressure casting.
- Q: As shown, how do I achieve the tightness test of this product, and achieve industrial production? Seek expert advice.
- Precise and tight sealing of the surface to which the test piece is to be tested, equipped with an airtight test instrument, and an electrical control system. You can complete automated testing equipment
- Q: How can the casting be plated with ordinary zinc plating? The coating is too thin and requires 0.08 thickness
- Hot galvanizingGenerally 0.06 mm or more
- Q: Where is the precision casting factory?
- The National Precision Casting Factory is generally distributed in Shandong, Ji'nan, Jiangsu, Wuxi, Changzhou, Zhejiang, Guangdong, Panyu, Dongguan.The above are only the main distribution, many of Shandong are made supercharger, and Guangdong to jewelry industry based.
- 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: 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
- Q: The difference between sheet metal and casting parts
- Casting parts are made by casting (followed by a variety of processing), the shape can be simple, can also be very complex, usually large parts, as a base, bed, work table, and so on, good seismic performance.
