Water Treatment

EPD’s four fold doors are well suited for use in waste treatment and transfer facilities for numerous reasons:

EPD can provide doors with cladding materials that stand up to the corrosive effects of the caustic chemicals and materials associated with these facilities.

Vehicular traffic from commercial trucks and private citizens present situations where a door may be hit and damaged.

  • Four fold doors open horizontally (sideways) and operate fast (2 feet per second), reducing the likelihood of damage.
  • In cases when the door does get hit, the heavy structural steel used by EPD in the door’s construction minimizes damage.

Doors can be insulated for heated environments and for use in severe weather conditions.

Vertical lift doors are available from EPD for larger openings.
