Purchase Manhole Cover Help

by Monroe Henson (2019-09-17)


Manhole covers are generally made of steel and are quite heavy. In fact every year many American Utility Staff will be injured due to the heavy covers. Fingers are crushed, heads banged and backs sent out of alignment. Today some metropolitan areas have gone to replacing the manhole covers with synthetic or composite covers that can take the same quantity of weight without cracking, don't rust, weigh considerably less and are not stolen to turn in for scrap metal.

Iron manhole covers often rust sending orange-ish mud and debris into underground utility holes and cause damage to components and contamination of ground water and urban run off storm drains with iron oxides.

You can find a couple of innovative companies already making these manhole cover covers from composite materials and several metropolitan areas are opting for the stronger, lighter and a lot more durable materials. Here are a couple of web sites to know more. One thing which has not been discussed is that since composite it made in layers, sensors may be contained within these units or covers. Sensors to detect underground gases alerting crews of toxicity or bad air, which is yet another killer amongst ground utility workers, can be quickly molded into the covers.

Sensors such as traffic counters with satellite relays can tell us of congestion, weight of vehicles and other important road upkeep upgrades needed. Sensors may also alert us of forced entry into our underground utility systems to protect against international Terrorism attacks. The new innovations in materials is well known in lots of industries such as aerospace, but we must also be looking at its uses underground because the sky isn't the limit of these new composite polymer based materials. Think on this.
