They regulate the movement of water, gases, dust, debris and environmental components.

Withstand Weights

Heavy-duty maintenance hole covers are located in heavy-industry spaces such as locomotive manufacturing units, shipbuilding factories, aerospace units, dockyards and steel production units. They are designed for the specific function of withstanding the heavy vehicular movement and weight in these areas.

The heavy-duty manhole covers remain intact despite heavy traffic running over them due to their strong weight-bearing capacity. These covers are capable of tolerating 400 kiloNewton/40 tonnes to 900 kiloNewton/90 tonnes of weight.

Offer Grips

These covers can be rough structures or loaded with patterns. In rainy seasons, the wet roads become slippery. These covers are the source of grip for both walkers and vehicle riders.
