Side wall columns are
2*80*80*4800 mm and are
made of galvanized steel
(hot-dip galvanized, 480 g/
m 2 ). Distance between side
wall columns is 2,5 m and
that for inside ones is 2,5 or
5 m, which is determined by
calculation of snow load.
For most regions brick wall
with height 40 cm is
required at the bottom of the
column to provide better
resistance to extreme
weather.
