Product Description:

1.Ductile 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.

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.

2.Main Features of the Ductile Iron Manhole Cover:                   

•High endurance

•High Strength

•Pressure Resistence

•Anti-corrosion

•Anti-theft

•Good visual effect

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. 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.FAQ:

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.
