The longtime leader in hopper car outlet gate design and manufacture, Miner now covers the car from top to bottom. DuraShield hatch covers are available in both round and square end-cover configurations to accommodate most 24” trough designs and are available in all standard lengths. The DuraShield is constructed of a high performance aluminum composite material (aluminum skin top and bottom and a solid polyethylene core) over a rigid frame. The result is a lightweight profile cover system that is more durable than fiberglass and lighter weight than all-aluminum hatch covers.
Miner DuraShield™ hatch covers offer maximum commodity protection by ensuring a consistent and reliable seal in real-world environments. Built for long service lifeand minimum maintenance.
