Larger greenhouses have perlins to increase strenght
in roof structures . A perlin can be a heavy or light
channel . It usually sits on top of a truss and is
bolted to the roofbars in the centre of he roof .
heavy perlin (at least 1/4” thick) requires 1/4” x
3/4” bolts . Smaller greenhouses use a light channel
– bolts used are the same as the greenhouse bolts,
1/4” x 1/2 .”
Installation of a perlin is a simple matter of sliding
the bolts into the roof bars and feastening the perlin
(see photos) .
Bolt Perlin with the open side facing up if you wish
to use it for hanging baskets .
