We manufacture FERT joists and provide the supplemental certificates.

• FERT joists are being used for the support of light-weight prefabricated ceilings, roofs, or floors.
• Being the supporting construction elements, FERT joists must meet defined static regulations.
• Besides the basic joist girders (girder 2ø7), in the case of wider spacings, additional girders are being built in (400/500). Girders design is calculated for the uniform distributed load q=4,80 kn/m2 and point load of p=2,0 kn/m2.
• Inter-floor constructions made of FERT joists are to be applied only in the constructions exposed to static pressure. If the dynamic pressure (machines, mobile units etc.) is present, they must not be built in because of the fragile construction that can be easily broken.
• Depending on the customers needs, the length of the joists & girders can vary
  from 1 to 6,40 m.
