Material:
Aluminium side plates with perforated aluminium mounting brackets;
with rolled-on U-profile made of rust-resisting special steel.
Flexible insert made of high quality synthetic rubber, long wearing, weather resistant, temperature resistant (-30ºC to +120ºC), extensively resistant to oils, acids and bitumen.
Standard colour | black, grey |
Production length | 4 m |
Special Properties:
- Good fixing by perforated mounting brackets.
- Suitable for high load.
- Positive connection of production length profiles by staggering the joints in the individual aluminium profiles
Installation instructions:
A 12 mm thick joint filler strip must be placed between the aluminium mounting brackets.
The height of joint filler depends on the overall height required, but it must be
sufficient to ensure that the screed is completely separated at the joint locations.
This strip also helps levelling the profile. The perforated legs of the profile are pressed
into the first fresh layer of mortar or screed and levelled. Then more screed is applied.
Depending on the thickness of the floor finish (measured from top edge of profile) the
profile must oversail the screed to suit.
