    Heavy Duty Ductile Cast Iron En124 Standard F900 Airport ...
    Cast iron airport manhole covers and frames are specialized, extra-heavy-duty components engineered to withstand immense loads (up to 900 kN or more) on runways and taxiways. They are commonly manufactured from gray or ductile iron for high compressive strength. These covers are often bolted or gasket-sealed to prevent displacement from jet blast and aircraft weight. 
    Key Features of Airport Manhole Covers: 
    • High Load Capacity: Designed for "extra heavy duty" (E600 or F900 ratings) to support heavy aircraft traffic, far exceeding standard road loads.
    • Material: Usually made from ASTM A48 Class 35B gray iron or ASTM A536 ductile iron.
    • Security: Features such as bolting or locking mechanisms are common, sometimes using gasket seals for watertight requirements.
    • Dimensions: Common sizes include 38-inch diameter, with various square or rectangular options for specific infrastructure.
    • Anti-Slip Surface: Castings often include raised patterns to prevent slippage on paved areas. 
    Typical Specifications & Types: 
    • Neenah R-3492-B: A common 38" diameter airport casting.
    • Rectangular/Square: Often used for specific telecom or drainage access within airport environments.
    • Installation: Involves setting the frame securely into concrete or asphalt, ensuring it remains flush with the pavement. 
    For specialized procurement, these are often sold by industrial foundries and airport construction specialists.
