Thus, unprotected
steel does not possess fire resistance, meaning that
special measures are necessary, such treatment

.2.7 Fastening steel structures
In industrial construction, steel constructions are fre-
quently used for the building structures.
As steel girders may usually not drilled through,
the only other option fastening with construction
clamps.g. Steel girders
and supports can also found power stations. steel girders are used natural con-
ductor, they are connected the earthing
system, then construction clamps able carry light-
ning current must used. 500 °C, steel loses half its res-
istance, that, there fire, the building struc-
tures are exposed high risk
