Complete package auxilaries like sleeves, supports, couplng rods
etc. |
|
| |
|
Fast
and reliable supply from our own factory |
|
| |
|
Optimal
profile shape, about 20% (strong side) to 75% (weak side)
stronger than comparable profiles from local suppliers |
|
| |
|
Because
of the high steel grade, on average 20% bigger span possible
compared to similar purlins |
|
| |
|
Extra
secondary stiffener, so no cutting edges for workers and quicker
and safer assembly |
|
| |
|
Eaves beams with distinct angle at no extra charge |
|
| |
|
Standard profile dimensions, supports and auxilaries are always
the same, independent on spans, truss distances etc. |
|
| |
|
Easy standardized details |
|
| |
|
Available for roof, wall and floors |
|
| |
|
Purlins
can be packaged per wall, roof and axis with no extra charge |

|
|

|
|
|
| |
|
Roof
purlins are produced at our own factory by measure and with
holes for assembly |
|
| |
|
3-span
purlins provides the greatest strength |
|
|
|
Use
sleeves to shorter purlins or assemble 2-span purlins staggered |
|
|
|
Keep a
space of approx. 15 mm between the truss and the purlin |
|
| |
|
Eaves beams are supplied
with an angled top flange, so only 1 profile is needed where
roof and wall meet instead of 2. See fig. A |
