The design for the APS Series aluminum floor doors is excellent for use in interior and outdoor applications where it is necessary for flood-tight or gastight performance.  The construction of the angle frame structure is for casting in concrete. The diamond plate door panel can withstand a live load of 1560 pounds per square foot (capable of holding up to 25 ft head of water). The door panel overlaps the frame, squeezing the gasket and ensuring a watertight/gastight seal.

Other features you can find include:

Material: Aluminum door & frame.
Lock/Latch: Type 316 stainless steel flood-tight cam locks and flush flood-tight handle.
Flange: 3/8 aluminum with 3/16 x 1 1/2 strap anchors welded around the frame for casting into concrete.
Hinge: Type 316 stainless steel butt hinges with tamper-proof stainless steel bolts and nuts.
Finish: Mill finish with a bituminous coating applied to the exterior of the frame.
