Special metal spreading anchors
are offered for false ceilings.
Injection mortar
The VMS Plus injection mortar system particularly
suitable for fastening hollow brick, concrete and
porous concrete, calcareous limestone, sand-lime
brick and masonry. Al-
though the load capacity the injection mortar sys-
tem below the load capacity when cold, this load
capacity completely sufficient for fireproof fastening
of the different routing types. This load data is
contained the appropriate European technical ap-
provals and appropriate test documentation.

Appropriate proofs are available for the tests carried
out. Although
the load capacity the anchors during fire below
the load capacity when cold, this load capacity is
completely sufficient for fireproof fastening the dif-
ferent routing types. The connection free from
spreading pressure and created through the form
fitting the injection mortar with the substrate and an
anchor rod.The components are tested and approved
for fire resistance period minutes.Metal spreading anchor
OBO Bettermann's metal spreading anchors for
mounting concrete were tested for fire protection. Depending the fire resistance length (up to
120 minutes), maximum load capacity was determ-
ined when anchored concrete. The maxim-
um load capacity depending the fire resistance
period and the fastening substrate documented ac-
cordingly the available fire protection certificate
