The frame of the system is made by riveting and welding. The parts are fastened on the frame with screws. Our other product series can also be used in constructing a system that meets the special needs of each purpose, as the parts of the F NBS system are compatible with the S-series.

S-series provides a wide range of sizes and uses the same door structure as the E- and F-series. The available door sizes range from 140 to 1960 mm.

The frame of the system has been provided with pre-punched holes and grounding screws to enable easy grounding. Doors are grounded via hinges and screws.

Screen-protected structures can be built on one or two levels. For two-level installation, either plastic or metal partition covers are used.
