Read the Case Study
Traditional, cast iron steam manhole covers can reach extremely high surface temperatures due to the conduction of heat from within the manhole. Furthermore, removal of heavy, cast iron covers often puts the operator at risk of back and shoulder injuries.
Initially, the university decided to replace two manhole covers that were located near their football stadium to eliminate the hazards presented by hot steam manhole covers.
Since installing Fibrelite steam covers, the university has experienced significant reductions in heat transfer from the vault to the manhole surface. Further installations across the campus have now been scheduled as part of a replacement program for numerous 24″ steam covers.

Fibrelite’s Composite Manhole Covers – Cool to Touch!
The thermal gradient properties of Fibrelite’s composite steam covers significantly reduce the heat transfer from a steam vault to the surface of the cover. Typically, the surface temperature of the cover will be slightly above the ambient temperature at street level even when subjected to extremely hot temperatures on the underside. Fibrelite’s composite access covers have been tested to temperatures up to 400°F while still maintaining their “cool to touch” properties and ability to support vehicular loads.
