Reasons to Use FRP Composite Manhole Covers and Rings
There are quite a few reasons why you should consider using FRP composite manhole covers and rings, as they are a very useful and popular alternative to manhole covers made with traditional materials. If you are thinking about purchasing them for your next project or have questions about them, this article will give you a good overview of their benefits and main features.
FRP Composite Manhole Covers have zero scrap value
One of the biggest benefits of using FRP composite manhole covers is the fact that they don’t have any scrap value at all. This means that they are far less likely to be stolen than metal manhole covers, as metal covers have a substantial scrap value.
Manhole cover theft has actually risen in recent years in several localities because of economic circumstances and rising crime rates. If your application happens to be in an any area where crime and theft is even remotely a concern, it is well worth it to purchase FRP composite covers rather than taking a risk and using metal. Remember that that there is a significant risk to people in any area where a manhole cover has been stolen, which is why FRP composite covers have been heavily adopted in China, India and other countries.
- Composite manhole covers are easier to work with and safer
Moving a cast iron manhole cover can sometimes take two to three people or equipment, as they can easily weigh 100 to 200 pounds or more. These bulky and gigantic manhole covers are also dangerous to move, as workers can have limbs crushed underneath them or easily strain their muscles, ligaments or back when lifting these heavy objects and moving them about.
FRP composite manhole covers don’t have this issue because they are plastic and weigh significantly less than cast iron. For example a 25 ½’ composite manhole cover is about 54 pounds, while a similarly sized cast iron cover is 180 pounds, over three times the composite cover in weight. This is a major inconvenience that can easily be solved with composite manhole covers, especially when workers have been injured in the past.
- Composite covers are durable, strong and lockable
The security of composite manhole covers superior to cast iron covers. Cast iron covers are often locked, but even the best locks can be cut through or otherwise compromised by clever thieves. FRP composite manhole covers are much harder to break into, and thieves have little reason to do so in the first place. They feature a worm gear or a locking mechanism that secures them in place. They are also fully traffic rated and are very durable and strong, just as one would expect with cast iron manhole covers.
There are plenty of other reasons why you should consider swapping traditional manhole covers for FRP composite. To learn more, contact Super Cover today at 956-281-2600.
