Take The Bite Out of Cast Iron

The GMI composite manhole cover and frame system provide an 80% average weight reduction when compared to similar iron products. This weight reduction prevents injury to personnel in the field during the installation and maintenance of underground infrastructure.

The injuries caused by heavy municipal castings are appalling: amputations of fingers and toes, limbs being crushed, repeated muscle strains and sprain, wrenched backs, and the repetitive trauma caused by a lifetime of lifting the impossible weight of a manhole cover. 

GMI composite manhole frames and covers are characterized by the light weight and ease of handling. Patented features to encourage proper lifting technique and safe handling are available as part of the GMI composite manhole cover and frame system. Injuries are prevented, and worksites are safer and more productive when using GMI products.

Added safety and accident reductions will also make an impact on the budget. Lost time accidents and workman’s compensation expense will decrease. Insurance premiums can be lowered saving the entire municipality a great deal of money.
