Manlid cover (composite)

The manlid cover (500 mm in diameter, installed with 6 or 8 swivel bolts) can also be purchased for existing container solutions, such as tank containers, tank wagons, trailers and removable containers. Thus, the benefits of composite material – resistance to chemicals, durability, low weight, energy efficiency, cleanability, suitability for foodstuffs – improve the properties of the existing container.

Benefits of a manlid cover

  • Excellent chemical resistance

  • 50% lighter but more durable than a steel hatch

  • 100 times higher energy efficiency than in steel hatches

  • Compatible with a steel collar
