The manufacturing material for the bearing frame is the steel metal profile, which provides the bearing capacity and geometric immutability of the building. The frame is developed in accordance with the requirements for the metal section factor specified in the certificate of conformity for the flame retardant used.

The adopted degree of fire resistance is justified by the design for structural fire protection of the metal frame. Non-load-bearing filler structures are made of certified materials with the required fire resistance limits.

The enclosing structures provide for unified cable entries with a seal, cable passage boxes, standardized blocks for passage of pipelines.

Depending on facility operating conditions and Customer requirements, the block-containers for fire suppression Vityaz can have a wide range of designs.
