What is the problem with cast iron covers?  This traditional choice for manhole covers has a long list of disadvantages and needs to be replaced with something new and ergonomic.  Virtual Polymer Compounds, LLC is here to provide the rapidly changing market with fiberglass manhole covers.

Fiberglass covers are a better choice for many reasons; first of all, they are will not rust or corrode and create a hazardous or noisy situation.  The clanging of a rotten iron cover will disappear from streets.

Fiberglass has a very high strength to weight ratio, which allows a strong fiberglass cover to weigh 80% less than an iron cover.  Heavy iron covers create a hazardous work environment and have been the source of on-the-job injury, such as removal of fingers and toes, crushed limbs, muscular damage.  Fiberglass covers eliminate these problems and lead to a safer working environment.

Fiberglass has no re-sell value, leading to zero thefts.  All covers come with a locking mechanism that will secure the manhole from intrusion.  Iron covers are routinely stolen and sold for their scrap value, which makes owners liable for hazardous street conditions.

Fiberglass has no metallic properties, which include electrical conductivity and interference with radio frequency and telecommunications.  Advanced equipment installed inside manholes can be used remotely without the cover blocking signals and radio waves.

Durable and strong, fiberglass covers are vigorously tested against traffic loading standards, and offer incredible performance in dynamic and static loading.

VPC Fiberglass offers are wide range or manhole cover frame and opening sizes, along with dome covers and rectangular hatches.  Custom design and engineering of manholes and covers are available, please call with any questions.
