Material:
Our hatches are made of 3 mm thick stainless steel, which increases their strength and resistance to deformation during installation, and the use of actuators makes opening even very large hatches easy.

Strength:
Class B125; the hatch should be filled with concrete, and there is additional reinforcement inside the flap.

Sealing:
EPDM gasket application, which, under the weight of the hatch, is properly compressed, giving us full waterproofing and odor sealing; in exceptional conditions, additional seals can be applied.
