Chapter The external lightning protection system
.
As steel girders may usually not drilled through,
the only other option fastening with construction
clamps.2.g. However, the supporting
steel elements the building are unprotected, other
technical equipment, e.7 Fastening steel structures
In industrial construction, steel constructions are fre-
quently used for the building structures.
At first, fastening support systems steel girders
seems barely possible. steel girders are used natural con-
ductor, they are connected the earthing
system, then construction clamps able carry light-
ning current must used.
However, approx. smoke extraction auto-
matic extinguishing systems, can compensate for the
bad properties the steel case fire limiting
the critical temperatures. Steel girders
and supports can also found power stations.2. Thus, unprotected
steel does not possess fire resistance, meaning that
special measures are necessary, such treatment
with fire protection coatings lining with non-com-
bustible plates
