9. Shims
Generally, the vehicle barrier system should be installed so that shims are not
required. However, if shims are required due to conditions on site, then the following
points must be observed:
·
The regulation centre distance of the posts is to be retained as far as possible.
·
If the longitudinal elements have to be sawn, it is to be ensured that the cut is
made clearly.
·
The cut is to be executed so that the swarf cannot damage the hot-dip
galvanised sections (risk of extraneous rust or damage to the coating).
·
The burrs are to be removed and the cut area is to be protected against
corrosion with cold-galvanizing paint in accordance with EN ISO 1461.
·
The hole pattern for joining a shim must correspond to the regulation design
and the gaps to the corners may not be smaller than those of the regulation
design.
·
Flame cutting is generally impermissible for installation work!
